Non-geostationary satellite systems – Licensing updates
1. Overview
One of Ofcom’s major priorities is getting everyone connected. We want to make sure people and
businesses can access key communications services and to improve access to broadband services in
the hardest-to-reach locations.
There are a range of terrestrial technologies that can provide broadband services. In addition,
satellite broadband can be suited to connecting remote areas which do not have reliable mobile or
fixed broadband. To date, the performance of these services has been limited by the time delay
(latency) caused by signals travelling the long distance to the satellite and data caps that are
commonly imposed. There are relatively few satellite broadband customers in the UK.
There are new broadband satellites systems being developed, which use many satellites in a non-
geostationary satellite orbit (NGSO) closer to the Earth than earlier satellites. These offer lower
latency and greater capacity. A number of companies are developing these systems (for example
Amazon, OneWeb, SpaceX, and Telesat) and we want to enable as many of them as possible to
provide services and increase choice for people and businesses in the UK.
NGSO systems are technically more complex than earlier satellite broadband systems as they plan to
use many hundreds, if not thousands, of satellites orbiting the Earth. Satellite dishes need to track
these satellites as they move across the sky, unlike existing satellite networks where the dishes are
fixed pointing at a single satellite which is stationary in the sky.
This means it is more complex for NGSO satellite operators to agree how to operate their networks
without causing harmful radio interference to each other. They are required to do this under the
International Telecommunication Union (ITU) Radio Regulations, although in many cases these
agreements are yet to be concluded. This creates a risk that interference between NGSO networks
could cause localised degradation to the quality and reliability of these services.
We therefore propose to update our approach to licensing NGSO systems. In particular, where
possible, we want to ensure that that quality of services is not adversely impacted. To do this we are
proposing new checks on interference risks when we consider NGSO licence applications, along with
greater visibility of those applications, as well as strengthening our ability to deal with harmful
interference if it occurs.
We also want to mitigate the risk of earlier systems hindering the deployment of those coming later
because of the interference they could cause, and therefore potentially restricting competition. To
do this we are proposing new checks on competition when we consider NGSO licence applications.

Non-geostationary satellite systems – Licensing updates
• Satellite (Earth Station Network). These licences allow the use of NGSO user terminals, for
example the dish and equipment installed at a customer’s premises, and must be held by any
satellite operator wishing to deliver services in the UK.
• Satellite (Non-Geostationary Earth Station). These licences authorise gateway earth stations
which are large hubs that connect the satellite network to the internet and/or to private
networks and cloud services.
The key changes we propose to the application process are:
• to include a check that systems being licensed can coexist without degrading consumer services;
• to include a check to guard against any restriction of competition that could arise if granting the
licence could prevent subsequent parties entering the market; and
• to publish applications for any licences which we expect to grant and allow a period for
comments where stakeholders can provide information regarding interference or competitive
impact.
The new licence conditions we propose would:
• require technical cooperation between operators;
• enable us, where required, to manage local cases of interference that are impacting services
thereby protecting UK consumers; and
• be included in new licences.
We would expect to update the small number of existing licences accordingly.
If we receive any licence applications during this consultation period, we will not progress them until
we have made a decision on the proposed process and licence conditions.
We want to ensure that all relevant satellite equipment would be subject to these updated rules and
therefore propose removing an existing licence exemption for certain user terminals (those
operating in Ka band).
We recognise the growing significance of these new systems to the space sector more broadly and
will be considering this in more detail as part of our Space Sector Spectrum Strategy, to be published
in the Autumn. We do not expect this further consideration will impact or remove the need for the
changes we are proposing now.
Next steps
The consultation closes on Monday 20th September. Following this consultation, we will confirm and
implement the appropriate licensing changes.
The overview section in this document is a simplified high-level summary only. The proposals we are
consulting on and our reasoning are set out in the full document

Non-geostationary satellite systems – Licensing updates
2. Introduction
2.1 One of Ofcom’s major priorities is getting everyone connected. We want to make sure
people and businesses can access key communications services and to improve access to
broadband services in the hardest-to-reach locations.
2.2 The deployment of new satellite broadband systems operating in non-geostationary orbit
(NGSO) is creating new options for people and businesses to access broadband services.
However, they may also create new challenges which we need to address to ensure their
benefits can be fully realised.
2.3 In this document we set out proposals to update our spectrum licensing approach in order
to manage the risk of radio interference between NGSO satellite systems, which can
impact the quality and viability of services, as well as safeguard competition. We believe
these updates are necessary and important now as systems are rolling out.
2.4 In the Autumn we will be considering the wider (beyond spectrum licensing) and longer
term implications of these systems as part of our Space Sector Spectrum Strategy.
2.5 In this section we introduce satellite broadband systems in general and the significance of
NGSO systems in particular; set out Ofcom’s duties and role; and outline the rest of this
document.

Non-geostationary satellite systems – Licensing updates
2.8 These existing systems have used one or more large satellites in geostationary orbit (GSO),
at around 36,000 km above the Earth’s equator. This means they remain in a stationary
position relative to the Earth (revolving at same speed and direction).
2.9 We are now seeing investment in new (Very) High Throughput GSO satellite broadband
services which offer the promise of much improved services, although the latency of
communications will be similar to existing GSO satellites. These new GSO systems could
contribute to the overall broadband landscape in the UK, but their basic architecture and
use of spectrum is similar to previous systems, so do not generally raise fundamental new
challenges for how we manage spectrum.
2.10 In contrast, NGSO satellites are set much closer to the Earth and move in relation to the
Earth’s surface. The lower altitudes of these satellites means lower latency services (as less
time is taken for a signal to travel to and from the satellite), which can improve the
consumer experience, particularly for interactive applications. Additionally, these satellite
systems require a fleet or “constellation” of satellites to ensure a continuous connection,
with some NGSO broadband networks in Low Earth Orbit (300-2,000 km from the Earth’s
surface) proposing to use hundreds or thousands of satellites. More satellites, each with a
smaller footprint, means the total capacity of the network can be higher than a single
geostationary satellite. Greater capacity means higher speeds can be offered and/or more
users can be served.
2.11 Table 1 below sets out some of the commercial NGSO systems currently being deployed or
planned based on publicly available documentation. This demonstrates that a range of
different network architectures and business models are being adopted for these systems.
2.12 A number of other constellations are being planned by operators around the world,
including in the UK. We have limited ourselves here to the constellations that are either
launching or plan to launch services in the next 2-3 years and could serve consumers in the
6

UK but recognise that there may be other operators in the future. Our proposals take this
into account.

2.13 The more dynamic nature of NGSO satellite systems introduces new challenges for
managing spectrum (discussed in Section 3), which have prompted to us to develop the
proposals in this document.

constellations and are indicated in the FCC references below. These may evolve.

Non-geostationary satellite systems – Licensing updates
2.20 Ofcom’s role can involve supporting satellite operators with their ITU filings and taking
such action as may be necessary to protect UK filings. This can include assisting with co-
ordinating their systems with other operators and administrations and helping to resolve
disputes where necessary. Ofcom is also responsible for representing the UK in
international forums that deal with spectrum, including at the ITU and European
Conference of Postal and Telecommunications Administrations (CEPT). In relation to
satellites, we help to develop international rules that support the efficient use of spectrum
by satellite networks, including by NGSO systems. For example, we supported new rules for
the ‘Bringing into Use’ of non-geostationary satellites systems that were agreed at the
ITU’s World Radio Conference of 2019.
2.21 Ofcom’s legal functions and duties for these activities derive from section 22 of the
Communications Act 2003. 17
17 (The judgment by Mr Justice Goldring in the case of the Government of Bermuda v Office of Communications & Ors
[2008] EWHC 2009 (Admin) (13 August 2008) gives a particularly clear explanation and summary of the legislative
background. It is available on www.balli.org.)

Non-geostationary satellite systems – Licensing updates
2.26 We also have a duty to have regard, in particular, to the desirability of promoting:
a) the efficient management and use of the spectrum for wireless telegraphy;
b) the economic and other benefits that may arise from the use of wireless telegraphy;
c) the development of innovative services; and
d) competition in the provision of electronic communications services.
Looking ahead
2.31 The nature of NGSO systems will continue to develop, with future generations already
being planned with more satellites, new frequency bands, greater use of inter-satellite
links etc. We are therefore also starting to consider future scenarios and use cases for
NGSO systems. These changes could bring further benefits to people and businesses
and/or introduce additional or different regulatory challenges.
2.32 We will consider these wider and longer-term implications of NGSO systems as part of our
forthcoming Space Sector Spectrum Strategy. We do not expect this further consideration
will impact the need for the changes we are proposing now.

Next steps
2.33 The consultation closes on Monday 20th September. Following this consultation, we will
confirm and implement the appropriate licensing changes.
Detail of proposals
2.36 Sections 4 to 7 set out the detail of our proposals:
• Section 4 sets out the new process we are proposing for NGSO licence applications.
• Sections 5 and 6 set out our proposals for new conditions in the licences authorising
NGSO user terminals (referred to as network licences in this document) and NGSO
gateway earth stations (referred to as gateway licences in this document). The new
licence conditions are listed in Annex 2 and 3.
• Section 7 sets out our proposal to remove licence exemptions for Ka band terminals so
that these will need to operate under the same type of licence as Ku band terminals.

3.5 Given the large number of NGSO satellites that are being deployed by operators, there is a
risk of satellites from two different operators appearing to be in the same part of the sky
(see Figures 3 and 4). Interference between different systems can occur as they line up in
the sky. This is referred to as “in-line event”. This interference can arise on:
• User links between the satellite user terminals and the satellite – both in uplink and
downlink directions (Figure 3).
• Gateway links between the satellite gateway earth stations and the satellite – both in
uplink and downlink directions (Figure 4).
3.6 This interference can disrupt the connection between an earth station and the satellite it
connects with, impacting the service provided to users.

Network 2
impact for users could be on their ability to send and/or receive data, depending on the
nature of the interference and the nature of the service being provided. For example:
• If a user is sending data (e.g. uploading a file) it may not get to its final destination as
intended or be delayed, due to harmful interference affecting the satellite-to-gateway
downlink and/or the user-to-satellite uplink.
• Conversely if the user is wanting to download data (e.g. watch a videostream) this may
be disrupted by interference to the satellite to user downlink and/or gateway to
satellite uplink.
3.9 Because the provision of broadband internet service to users depends on both the user link
and gateway link, interference arising on any of these links can disrupt or degrade user’s
internet connection. However, the impact of interference on gateway links would be much
greater than on individual user links as each gateway provides connectivity for many users
(perhaps hundreds or thousands of users depending on the design of the system), so a loss
of connection due to interference at the gateway will be experienced more widely across
the network.
18Systems may be entered into the Master International Frequency Register under No.11.41 of the Radio Regulations;
however, they shall operate on a non-interference non-protection basis with respect to those earlier systems where
coordination has not been achieved. If harmful interference is caused by the later system then under No. 11.42 of the
Radio Regulations the administration responsible needs to “immediately eliminate” it.
15
Non-geostationary satellite systems – Licensing updates
mitigate any negative impacts. For example, disputes may be referred to the ITU Radio
Regulation Board that meets three times a year, during which time there may be sustained
impact.
3.15 Therefore, we do not think we can solely rely on the ITU framework to effectively deal with
all concerns impacting NGSO services provided in the UK.
Gateways
3.17 We understand that NGSO gateways are likely to require large minimum separation
distances (for example 10s of kilometres or more) from the gateways of other systems, in
order to avoid harmful interference, even if there is agreement on coordination of the
satellite systems as a whole. 19 This results in a need for there to be some cooperation
between operators and/or a process for coordinating the location of gateway earth
stations within a country, in order to avoid sites being located too closely together.
3.18 This contrasts with GSO gateway earth stations, as multiple GSO gateways can be located
on a single site, each communicating with a different satellite system in a different orbital
location, without causing harmful interference to each other (see Annex 1). This means
that GSO operators do not have to be concerned about where other GSO operators are
locating their gateway earth stations.
3.19 If the separation distances needed between NGSO gateways were to be very large (say
much greater than 100 km) and/or demand for sites were sufficiently high, then this
introduces the possibility of a scarcity of sites within the UK. This scarcity could contribute
to competition being restricted if enough sites were acquired by a single player (or
concentrated number of players) such that other operators requiring UK sited gateways
could not enter the market.
3.20 At present we do not think there is a significant risk of this scarcity materially constraining
the deployment of NGSO systems in the UK. This is because not all systems will technically
depend on a gateway in the UK in order to be able to offer services in the UK, and our
understanding is that those that do would need only a limited number of gateways
(depending on their system architecture). Based on the current information that operators
have provided to us about their plans for gateways, we believe that sufficient sites will be
available.
19The requirement for a minimum separation distance can in principle be avoided for NGSO user terminals if there is a
choice of satellites for the terminal to point at, thus avoiding the possibility of an in-line event. Gateways may not have a
choice of satellites with which they need to communicate, although this will depend on the design of the system.
16
Non-geostationary satellite systems – Licensing updates
3.21 However, scarcity of sites could be (artificially) exacerbated if the separation distance
needed to protect a gateway were to be very large as a result of unrealistic levels of
protection being claimed; and/or if operators apply for gateway licences that they never
actually use for a real system.
3.22 In addition, there are uncertainties over how the design of NGSO systems will develop in
the future, with technology and system architecture changes potentially increasing or
decreasing gateway requirements. We will continue to engage with stakeholders (including
through our Space Sector Spectrum Strategy consultation in the Autumn) to understand
their future plans for future generations of NGSO systems.
User terminals
3.23 A lack of agreement over how user terminals of different systems can coexist in the same
area and band could restrict competition as a result of earlier deployed systems hindering
later ones.
3.24 Once one operator starts deploying user terminals, other operators wishing to launch
services using the same band may expect to experience harmful interference from the
existing user terminals. In the worst case this could mean that the quality of their
broadband services would not be sufficiently reliable in order to enter the market.
Nonetheless, the established player could have an incentive to cooperate given that the
interference is likely to be mutual, i.e. their services could be degraded as well.
Encouraging cooperation
3.26 Cooperation between operators is key to avoiding the risk of disruption to NGSO
broadband users. As noted above, there are obligations to coordinate under the ITU Radio
Regulations (where operators are filed through different administrations), but our
international role is limited to encouraging coordination by or with UK filed systems. In
addition, ITU coordination does not tend to deal with the specific siting of gateway earth
stations within a country.
3.27 We are therefore proposing to introduce an additional explicit licence condition requiring
NGSO licensees to cooperate so they can co-exist and operate within the UK without
causing harmful radio interference to each other. We are proposing to introduce this
condition into NGSO network licences, as this licence should be held by the entity
responsible for coordinating the entire system. Section 5 on network licences includes this
proposal.
17
Non-geostationary satellite systems – Licensing updates
3.28 For the avoidance of doubt, this would complement (and not change or replace) existing
obligations that licensees may have to coordinate under ITU coordination procedures.
3.29 Cooperation between operators in relation to the siting of gateway earth stations can also
be improved by us publishing applications for new licences before granting them. This
should assist Ofcom and operators in identifying potential interference risks and taking the
steps required to mitigate these. For example, the additional transparency could alert
other operators who are considering establishing a site, or nearby sites, for their own
gateway, to potential for interference issues. Section 4 sets out our proposals for updating
our licensing process to include publication of licence applications.
Managing interference
3.30 We are proposing two measures to manage the risk of interference adversely impacting
NGSO broadband services. They seek to avoid this situation arising and to deal with it if it
does. We would:
a) Introduce checks when we issue new NGSO licences so that these are only granted if
all systems (existing and new) are able to coexist and provide services to end users.
These checks are explained in Section 4 where we set out the new process.
b) Introduce new conditions into NGSO licences enabling us to take action to resolve
degradation to services if this were to occur at a particular location or location(s) in the
UK. These conditions would be included in network licences (see Section 5) and
gateway licences (see Section 6).
3.31 We are also proposing changes (in Section 7) that will ensure that operators with Ka band
user terminals will need to hold a network licence, and so would be subject to the same
conditions as those with Ku band user terminals (who already need to hold a network
licence).
Supporting competition
3.32 As discussed above, there is potential for the deployment of NGSO gateways and user
terminals to create competition concerns by introducing barriers for future systems.
3.33 To guard against these risks we are proposing to introduce a competition check into our
process (see Section 4) for issuing new NGSO licences for gateways and user terminals.
This check would need to take into account of the technical constraints that the gateway or
user terminals could create on future licensees. If they need too much protection or have
too little flexibility, then they would be more likely to restrict competition from emerging.
3.34 Our proposals above to encourage operators to cooperate and to manage interference
risks will also support competition by enabling multiple systems to coexist.
3.35 In addition, the risk of scarcity of gateway sites can be reduced by introducing a
requirement for gateway licensees to commence and maintain transmissions within 12
months.

Consultation questions
Question 1: Do you have any comments on our assessment of the interference challenges
raised by NGSO systems and their potential impact on a) service quality; and b)
competition?
Question 2: Do you have any comments on our approach to dealing with the interference
challenges raised by NGSO systems?
19
Non-geostationary satellite systems – Licensing updates
Managing interference
4.5 In issuing new licences our aim is to be satisfied that it is reasonable for all authorised
systems to be able to coexist (in bands they are using in common), such that they are all
able to provide good quality services to their users. Our intention is not to specify how this
coexistence should be achieved, as we believe this remains best determined by the
companies involved, including through the established ITU process for coordinating
satellite systems.
4.6 This means that the actions that operators take to coexist with each other could involve
reasonable mitigations and adjustments by any or all parties, including existing system
operators agreeing to take reasonable action to accommodate new ones as a result of an
ITU coordination agreement.
4.7 We are proposing to continue considering licence applications in the order we receive
them, but that earlier licence applications should not have the ability to block later systems
if it is reasonable for them to be able to coexist. We propose that in practice this would
mean that:
20
Non-geostationary satellite systems – Licensing updates
a) For gateways operating under a NGSO earth station licence: We would want to avoid
authorising new gateway earth stations that are located too close to existing gateway
earth stations such that (even with reasonable mitigations by either party) one or both
would be unable to operate and support services to end users without experiencing
harmful interference.
b) For earth station network licence authorising user terminals: We would want NGSO
terminals authorised under such a licence to be able to coexist with other authorised
NGSO systems (gateways or terminals), taking account of the ability of either party to
make reasonable efforts to mitigate interference.
4.8 In undertaking these assessments, we would take into account information which previous
applicants have provided about the technical flexibility of their system (see competition
discussion below).
4.9 Note that in the following section we also propose an obligation for all holders of network
licences to cooperate with other licensees to ensure that the NGSO system they are
responsible for can coexist with others authorised in the same band.
Competition
4.10 Our aim is to reduce the risk that issuing the licence(s) applied for (if combined with other
licences held or applied for by the applicant) would restrict competition. In particular, we
would be concerned if issuing the licence(s) had the effect of creating barriers to
competition emerging in the market. The implications for gateway and network licences
are discussed below.
4.11 As noted in section 3, gateway earth stations of different NGSO systems may require large
separation distances, for example 10s of kilometres or more, in order to avoid harmful
interference, which has the potential to be a constraint on the number of licences that
could be accommodated in the UK.
4.12 The number of gateway earth stations needed in the UK, if any, in order to offer UK
services will vary from system to system. Some will not technically require a UK gateway as
they will rely on a gateway in nearby countries or may require one at most. Others may
require a small number say 4 or 5. Given this, and the range of options for siting earth
stations across the UK, we propose that it is reasonable to continue to issue licences as
people request them provided that we have the opportunity to consider/take account of
any competition concerns arising from an application (for example, if one or a number of
operators was seeking to acquire licences for a large number of sites) which would limit
options for others to the extent they could not enter the market.
4.13 In considering whether acquisition of additional gateways could restrict competition, we
propose that a relevant factor would be the extent to which the satellite system has the
flexibility to accommodate other operators deploying gateways near to them in the future.
For example, systems which are likely to require other gateways to be at least 200 km
21
Non-geostationary satellite systems – Licensing updates
away from its own gateways (whilst recognising this is a function of both systems) would
likely raise greater competition concerns than those that are flexible enough to
accommodate others much closer.
4.14 A network licence is necessary for an operator to deploy user terminals in the UK. 20
Therefore issuing a new network licence supports market entry, and has the potential, if a
service is deployed, to support greater competition (assuming as discussed above that it
can coexist with other authorised systems).
4.15 Therefore, competition concerns would primarily arise from the constraints that systems
operating under a network licence could impose on subsequent entrants due to the
technical barriers to coexistence between systems (e.g. due to lack of flexibility in the
design of systems). In particular in a market that was concentrated, if there was limited
prospect of the licensee system and future systems (applicants) being able to technically
coexist, then this could form a barrier to future entry to the market.
4.16 As a result, we are proposing that a key piece of information that applicants should provide
when applying for a network licence is credible evidence about the technical ability for
their system and future systems to coexist. This would include evidence about the
flexibility of their system and/or what reasonable steps new licensees could easily
undertake to protect them. This information would also be used when assessing whether it
is reasonable for new applications and existing services to coexist, to understand the
reasonableness of mitigations being undertaken by existing licensees.
Order of processing
4.17 We believe that each of these objectives can be achieved whilst continuing to process
licence applications in the order that we receive them. As a result we are proposing to
consider each (complete) application in the context of existing issued licences and earlier
applications.
4.18 However, and for the avoidance of doubt, this does not affect our support for operators
undertaking coordination of their satellite networks in accordance with the ITU Radio
Regulations. Successful coordination in accordance with ITU coordination procedures, such
that multiple NGSO systems can coexist and compete in the UK, supports our national
licensing objectives.
Overview of process
4.19 In light of the objectives above, we propose to introduce a new process for considering
non-geostationary licence applications, which will provide an opportunity for stakeholders
to comment. In summary, we propose to:
20 See our proposals in Section 7 to bring Ka band user terminals in line with Ku band user terminals
22
Non-geostationary satellite systems – Licensing updates
23
Non-geostationary satellite systems – Licensing updates
4.22 Each licence application would have its own separate process which would be initiated
when Ofcom receives the licence application. Applicants would need to submit the
relevant licence application form(s), along with the following additional information:
• Coexistence with other NGSO systems. Applicants should demonstrate how
coexistence is possible between their networks and:
- Existing non-geostationary systems that are already licensed in the UK.
- Non-geostationary systems that have applied for a licence and whose application
has been published for comment.
- Applicants can demonstrate coexistence preferably by stating that an agreement
with the other party already exists, or if that is not available providing a technical
coexistence analysis. 21 In the former case, Ofcom will check with the other parties
that the agreement exists.
• Ability to coexist with future NGSO systems. As noted above, the competitive impact
of issuing a new licence will depend on the ability of the system to be able to coexist
with future networks. Therefore, the applicant should state what flexibility their system
has to coexist with future networks. These should include the measures they would be
able to put in place if another network comes along in the future, and the expected
benefits of such measures; it could also suggest measures future networks could
reasonably be expected to put in place in order to coexist.
• Competitive impact. Optionally, applicants would be able to provide information on
the competitive impact of issuing the licence (combined with other licences held or
applied for by the applicant). This may refer to their ability to coexist with other
systems.
• Ability to comply with NGSO conditions. The applicant would state that they have the
ability to comply with the terms of the licence, in particular the new NGSO conditions
that we are proposing. Sections 5 and 6 set out the conditions we are proposing to
include and the responsibilities these imply for the licence holder. In particular:
- Those applying for a network licence – we would expect them to have control over
the whole satellite network (including the associated user terminals and gateway
earth stations) and the ability to negotiate and agree coexistence arrangements
with other licence holders, so that they are able to comply with the conditions
associated with that licence.
- Those applying for a gateway licence – we would expect them to have control over
the gateway earth station. In addition, applicants for gateway licences would need
to state that they are operating with a satellite system for which we have issued a
network licence (and state the licence number and licensee) to an appropriate
entity. This would be to ensure that there is an entity with the responsibility and
ability to agree coexistence for the whole satellite system (including the gateway).
21 As a reference, applicants may consider the type of technical analysis usually carried out during bilateral coordination
discussions, e.g. comparison of the statistical distribution of the interference-to-noise ratio (I/N), impact on average
spectral efficiency and availability, etc.

4.23 The licensee may indicate that some of the additional information requested is
commercially confidential if they do not wish Ofcom to publish this alongside their
application.
4.24 If the standard licence application form(s) were not completed correctly, or if the
additional information set out above was not submitted, Ofcom would ask the applicant to
provide additional information where appropriate and to re-submit their application.
4.27 If the application is to vary an existing gateway licence, we would assess whether the
changes would increase the interference environment that is already imposed by the
gateway site. For example, if the application adds additional antennas operating within the
same frequencies already authorised by the licence, we may decide there is no impact and
therefore issue the licence without inviting public comments. On the other hand, if we
decide that an application to vary an existing gateway licence changes the interference
environment, for example if there are additional frequencies or increased transmit power,
then we intend to proceed with the proposed new licensing process including the
commenting period.
Commenting period
4.28 Under these proposals, once Ofcom publishes details of a licence application, a short
commenting period will begin, allowing anyone to make representations on matters
related to granting the licence. The commenting period would normally run for four weeks.
Each licence application would have its own separate commenting period, so it is possible
there may be multiple commenting periods running in parallel.
25
Non-geostationary satellite systems – Licensing updates
4.29 If we publish an application for comments, we intend to provide a response form and the
closing date for responses. We would also notify stakeholders that we have published a
licence application.
4.30 We would expect the response form to provide specific questions that stakeholders should
answer with respect to the licence application, including the feasibility of coexistence and
the impact on competition. As we do for other Ofcom consultations, we would publish
responses in full on our website unless a respondent specifies that all or parts of their
response is confidential.
Ofcom decision
4.31 Following the end of the proposed commenting period, Ofcom would review the responses
and publish a decision on whether or not to grant a licence. As part of this process, we may
wish to make additional assessments on matters related to technical coexistence and
competition.
4.32 We would then publish our decision setting out whether or not we will grant a licence and
the reasons for making the decision.
Timeline
4.33 Under these proposals, we would aim to follow the indicative timeline shown in Figure 5,
however we may need to extend these timings in certain situations, for example if the
coexistence and competition assessment is particularly complex or if we were to receive
multiple licence applications in quick succession. If we need to allow a longer commenting
period, we would do this by setting an appropriate closing date when we publish the
application for responses.
Consultation question
Question 3: Do you have any comments on the proposed updates to our process for
NGSO gateway and network licences?
26
Non-geostationary satellite systems – Licensing updates
27
Non-geostationary satellite systems – Licensing updates
5.6 A number of NGSO satellite systems may be licensed to operate in the UK, and these
systems may overlap in some or all of these frequencies that they operate in. The
overlapping frequencies may include the bands used for links between satellites and
gateway earth stations, and/or the bands used for links between satellites and user
terminals.
5.7 As already discussed, in order for these systems to operate and provide services to end
users in the UK, there needs to be some arrangement for them to be able to coexist in the
frequencies that overlap.
5.8 Therefore we are proposing to introduce conditions that will require NGSO licensees to
cooperate with the other NGSO licensees operating in the same frequencies to enable their
systems to coexist, so that each satellite system is able to offer services to end users.
5.9 Note that although the network licence is authorising the use of the user terminal to
satellite links, the proposed requirement to cooperate so that different systems can coexist
applies to the whole system - comprising the satellites, earth stations and user terminals.
This is because (as discussed in section 3) the service provided to end users in the UK can
be negatively affected by harmful interference arising on a number of different links in the
system, including the uplinks and downlinks to/from gateway earth stations.
5.10 Satellite network coordination as required under the ITU Radio Regulations is the most
important element of the cooperation needed, although it may not always be sufficient to
ensure that services can be provided in the UK. In particular:
• Coordination between networks filed through the same country is not dealt with under
the Radio Regulations, which only deals with coordination between different countries.
• Even where a ITU coordination agreement exists, this may not deal with the specific
locations of gateway earth station sites within the UK, even if the general conditions
for coexistence between gateways is. Therefore, given that the NGSO gateways for
28
Non-geostationary satellite systems – Licensing updates
5.11 Ofcom will identify which NGSO licensees are operating on common frequencies and notify
this list to the licensee. In determining this list we will review all licensees holding NGSO
network licences and NGSO gateway earth station licences and establish whether the
frequencies used 22 overlap with any of the other NGSO licensees. We will initially do this
following the conclusion of this consultation and will thereafter update the list, and notify
licensees if appropriate, following the issuing of new NGSO licences.
5.12 Under this condition we would expect to notify that the “NGSO licensees” are:
• Network Access Associates Ltd (UK) (trades under the name “OneWeb”)
• Kepler Communications Inc.
• STARLINK INTERNET SERVICES LIMITED (Starlink satellite broadband services are
provided by SpaceX)
5.13 As coordination discussions can take many months, we would wish to see evidence that
they are progressing in a timely fashion and that both parties are participating
constructively. We may ask licensees for evidence on the progress of these discussions and
may facilitate discussions between operators in order to ensure sufficient and timely
progress is made.
5.14 In addition, in considering whether licensees are cooperating sufficiently and making
satisfactory progress under this condition, we may take account of:
• The practical feasibility of licensees cooperating to ensure coexistence, if for example,
the design of the systems operated by other NGSO licensees is not yet sufficiently
completed or stable.
• Whether services are intended to be provided by other NGSO licensees and when they
are expected to be provided. If no services are intended to be offered by other NGSO
licensees then coexistence between systems becomes irrelevant.
5.15 Failure to cooperate under condition 2, “such that network services can be provided to end
users” will increase the likelihood that user services will be disrupted such that the
conditions 3-5 (discussed below) are triggered.
22 Note that the network licence currently authorises the use of multiple bands, not all of which may be planned to be used
by the licensee. In this case Ofcom may seek additional information from the network licensees in order to establish which
ones are overlapping in frequencies actually used or planned to use.
29
Non-geostationary satellite systems – Licensing updates
• one (or more than one) of the NGSO Licensees suffers a material and recurring
degradation of services to its users at a specific region or location in the United
Kingdom; and
• the degradation of services is resulting from radio transmissions from the earth
stations, the satellite or any other part of the satellite system operated by another of
the NGSO Licensees, including the Licensee;
Ofcom may instruct the Licensee to cease or change the use of particular equipment or
particular radio frequencies which are authorised under a wireless telegraphy licence
(including but not limited to radio frequencies authorised under this Licence) and are
used by any part of the satellite system.
4. Any such cessation or change must be for the purposes of ensuring that such
interference is avoided and the degradation of services to users at the particular
regions or locations is resolved.
5. Following receipt of such notice, for such period of time as may be specified in the
notice, the Licensee may only operate in accordance with the terms and conditions of
the notice.
5.16 The aim of draft new conditions 3-5 is to enable us to require operators to take action,
including requesting a change of frequency if needed, in cases of interference between
NGSO systems which materially degrades the provision of services to users in specific
location(s) in the UK.
5.17 In considering whether to take action under condition 3 we propose that we would
consider:
• Whether there is a material and recurring degradation of services to users in the UK.
What constitutes material degradation will depend on the nature of the service being
offered, for example, what is ‘material’ would vary between a high reliability link to a
business customer and a consumer broadband service. Evidence we may look at could
include degradation to availability, throughput (both uploading and downloading data
from the user) and signal to noise ratio at the user terminal. We recognise that any
impact of NGSO-to-NGSO interference is likely to be recurrent, rather than continuous,
in nature due to satellites of both systems moving in non-geostationary orbits.
• Whether this degradation is being caused by transmissions from a NGSO operator
(rather than for example some fault or limitation arising solely within one particular
NGSO system). In establishing this we are likely to consider the timing of degradations
30
Non-geostationary satellite systems – Licensing updates
to user services and the correlation of that timing with (predicted) in-line events
between two different NGSO systems (based on ephemeris data).
5.18 Consistent with our regulatory principles, 23 we would look to see if operators have
attempted to resolve issues between themselves and whether it is possible for them to do
so, before resorting to regulatory action, and aim to ensure that any action we do take is
evidence-based and proportionate.
5.19 The specific action we will require will depend on the facts of the situation, but may
include changing the frequencies used by earth stations at specific location(s), changing the
power levels used by a particular earth station, introducing an angular separation between
satellite systems or – in the most extreme cases – switching off equipment. Factors we will
take account of would include statutory duties, including ensuring the optimal use of
spectrum, and the UK’s responsibilities under the ITU Radio Regulations including, where
appropriate, the status of the filings supporting those systems.
5.20 If we consider that it is appropriate and proportionate to take action, then we will send a
notification to the licensee telling them what they should do to rectify the degradation of
services to consumers, and when they should do it.
ITU obligations
5.21 As noted in section 2 it is the regulation of radio frequencies within the UK, under the
Wireless Telegraphy Act licensing regime, which is the focus of the document and the
proposals in it. The licensees holding Wireless Telegraphy Act licences, including the
network licence discussed in this section, may separately have obligations that flow from
the ITU Radio Regulations. We are proposing to add a new note, for avoidance of doubt,
that the conditions in the licence do not affect these obligations.
is unlikely to have the required control over the whole system, nor have the role of
agreeing how the NGSO system will coexist with other NGSO satellite systems.

Question 4: Do you have any comments on the proposed updates to existing and new
NGSO network licences?
32
Non-geostationary satellite systems – Licensing updates
operator, the licensee may not have control over the wider satellite network and, related
to this, does not take responsibility for coordination discussions with other satellite
operators. Therefore, we are not proposing to include the equivalent of condition 2
(requirement to cooperate with other licensees) that is included in the earth station
network licence.
6.8 Although we are not proposing to include a condition requiring cooperation with other
licensees in the gateway licence, there will still be a need for cooperation (for example
between satellite operators) to ensure the gateway can co-exist and operate without
causing harmful radio interference to other satellite systems. This role should be
undertaken by the entity holding the network licence.
6.9 Therefore we are proposing that the gateway licence includes a condition (draft condition
2) that requires it to only used with a satellite system which has transmissions authorised
under a network licence. In other words, so long as there is a network licence which covers
the satellite system with which the gateway is communicating, we believe this will be
sufficient to ensure there is appropriate cooperation.
34
Non-geostationary satellite systems – Licensing updates
• one (or more than one) of the NGSO Licensees suffers a material and recurring
degradation of services to its users at a specific region or location in the United
Kingdom; and
• the degradation of services is resulting from radio transmissions from the earth
stations operated by the Licensee;
Ofcom may instruct the Licensee to cease or change the use of particular equipment or
particular radio frequencies which are authorised under this Licence.
4. Any such cessation or change must be for the purposes of ensuring that such
interference is avoided and the degradation of services to users at the particular
regions or locations is resolved.
5. Following receipt of such notice, for such period of time as may be specified in the
notice, the Licensee may only operate in accordance with the terms and conditions of
the notice.
6.10 Proposed conditions 3-5 of the gateway licence are similar to those proposed for the
network licence in section 5 and have a similar rationale, to enable us to deal with cases of
interference between satellite networks. However condition 3 in the gateway licence is
simplified to reflect that the licensee may be a teleport operator and, if so, will not (unlike
a satellite operator holding a network licence) have control over other elements of the
satellite system beyond the specific link authorised under this licence.
6.11 Otherwise our explanation and proposed guidance on use of these conditions is unchanged
from that set out in the previous section.
6.12 As discussed in section 3, although we think the risk of real scarcity in gateway sites is low,
there is a risk of artificial scarcity if operators apply for licences far in advance of a
35
Non-geostationary satellite systems – Licensing updates
potential need and then never actually deploy. To mitigate this risk we are proposing to
introduce a requirement for gateway licensees to commence and maintain transmissions
within 12 months.
6.13 The licensee will have to start transmitting within twelve months of being issued a licence
and continue to remain operational after this. If spectrum is not used in this timeframe or
is subsequently no longer used, Ofcom may revoke the licence with one month’s notice.
Alternatively, we may no longer take this licence into account when assessing the
interference that may be caused by a new site when considering a new licence application.
ITU obligations
6.14 As for the network licence, we are proposing to add a note for the avoidance of doubt in
relation to obligations under the ITU Radio Regulations.

bands, 25 were previously awarded on a technology neutral basis. Further information about
the holders of these ‘Spectrum Access’ licences, including the specific frequency bands and
geographic areas, can be found on Ofcom’s website. 26
A1.8 Although not limited to satellite use, the spectrum covered by these Spectrum Access
licences can be used by transmitting satellite earth stations. Because the licences are
tradable (both leasable and transferable), earth station operators can access the spectrum
by making commercial agreements with the Spectrum Access licence holders. More
information and guidance about spectrum trading can be found in Ofcom’s trading
guidance notes (document OfW513). 27

these applications) as they typically provide services to a range of different sectors (e.g. air,
maritime and rail). There is, however, no formal requirement to do so.
Geostationary satellite
remains at a fixed position relative to the ground
A1.15 Many GSO satellite services operate on a co-channel basis, i.e. they use the same
frequencies in the same location. For some wireless services (like terrestrial mobile
services) if operators used the same frequencies in the same location there could be
harmful interference between them. However, multiple geostationary operators can
operate using the same frequencies and provide services in the same location because:
• Satellites are spaced out in the sky (for example, separated by at least 2 degrees).
• Satellite dishes on the ground are fixed to point quite precisely towards a specific
satellite in the sky.
• By pointing at different angles to different satellites, interference between satellite
systems can be avoided (see figure below).
