REPORT About Airport and aircraft Communication.

Airport Communications: The Future is Wireless

Without faultless communication systems, airports would not be able to
function on a daily basis. Elisabeth Fischer finds out how aging infrastructure
and incompatible systems are pushing many operators towards wireless
solutions

The question for airports today is not whether to implement a wireless network,
but rather how to implement it. Aging infrastructure and incompatible systems
push many operators towards wireless surface solution.
Passers-by had to do a double take at the massive sculpture in one of the
hallways of the Ronald Reagan Washington National Airport in Washington DC
in March and April this year. ‘Wireless’ was written there, in big letters, with
the distinctive universal wireless logo used instead of the dot on the “i”.
A representation of the wireless communications industry by the International
Association for the Wireless Telecommunications Industry, the sculpture is a
clear indicator of the direction that communication processes at airports are
heading in. Wireless applications have also pervaded the management of
airports ? just as they have in countless other industries.
Sébastien Fabre, network and mobility director of Specialists in Air Transport
Communications and It Solutions (SITA), believes that wireless systems
“enable significant improvements in operational efficiency and real-time
information exchange”.
The global company, which specialises in communications and IT solutions for
airports and is headquartered in Switzerland, has long realised the potential of
wireless for airports. Business travellers want internet access, airport retailers
need to communicate, security staff need network connectivity, air traffic on the
ground needs to be handled and airlines want to exchange information with
airport departments.
“
Current systems are very reliable and they need to be as they support mission-
critical operations.”
“SITA has witnessed an impressive growth of demand for both passengers as
well as professional users, especially in the area of baggage management and
process mobilisation,” says Fabre.
Wireless airports
A number of different wireless solutions can be used at airports to enhance
communications. These are mostly digital solutions, and include WiFi networks
for data and voice, GPRS and 3G, as well as professional mobile radios. The
applications can be used to mobilise most airport processes from maintenance to
security and asset tracking.
“Current systems are very reliable, and they need to be as they support mission-
critical operations,” explains Fabre. “Our system designs try to prevent a
specific service from ever going down. At all times the right balance is found
between the ideal system architecture and its cost to the customer.”
The infrastructure of an airport wireless system can roughly be divided into two
areas: airside wireless and terminal wireless systems. The first area includes
communication handling for planes, caterers and mechanics, as well as security
solutions such as cameras and perimeter security. The second area includes all
communication within the terminal between airline employees, the passenger
flow process, and communication between security and first responders.
Airport communications challenges
The size and architecture of airports complicate the implementation of wireless
systems, which have to be reliable, redundant, easy to use and robust. “The
biggest challenge is the need to provide coverage inside a large building while
at the same time covering a large area outdoors, and this must be done while
paying close attention to the final cost,” says Fabre. “A unique situation for
airports is the presence of the large metal bodies of aircraft, which can pose a
challenge for radio transmission and reception.”
Wireless communication systems face another problem. As different airlines
 and other air transport industry players use an airport’s network on a regular
basis, a global standard WiFi service is necessary to regulate the traffic on the
runways without failure of the system. SITA, for instance, has overcome this
problem with a system that interconnects local WiFi providers at different
locations.
“With this system, an airline can use the same mobile devices at any airport
without any configuration change,” explains Fabre.
Wireless runway lighting systems
The extent of how far the use of wireless technology at airports can go is seen in
the example of runway lighting systems, used to ease aircraft movements. With
traffic of, for example, ten million flights in the US alone every year, a reliable
system is probably the most important factor for the safe and controlled aircraft
handling at active runway intersections.
“The biggest challenge is the need to provide coverage inside a large building
while at the same time covering a large area outdoors.”
Usually, the lightning infrastructure on the airfield, which includes the runway
and taxiway edge lights, threshold lighting, airfield guidance signs and the
apron areas where aircrafts are loaded and refuelled, is managed and
communicated over fibre optic cables. The cables run all around the airport and
are therefore in danger to be damaged during works. The control system could
be knocked offline ? with fatal results for the traffic on the runways.
Several airport IT providers have started to consider the advantages of those
wireless networks as a back-up to fibre lines. One driving factor is the reduced
installation and maintenance costs of wireless applications.
The underlying idea is that if a fibre system goes down, the communications
and operations of the lightning system would continue flawlessly on a wireless
radio network.
Today, most airports have switched to a radio network as the primary line of
communication for lighting systems, triggered by economic and structural
advantages compared to fibre.
Case study: Düsseldorf International Airport
One of the airports realising the benefits of wireless applications is Düsseldorf
International Airport, Germany’s third largest airport after those of Frankfurt
and Munich. With an average of 600 aircraft movements a day and 19 million
passengers in 2010, every single step in the airport communication is heavily
dependant on reliable technologies and systems.
In 2008, its management decided to replace the airport’s wired system with
wireless communication applications, to meet the increasingly high demand of
operational processes. SITA, which provided its professional mobile radio
solution, met the special requirements of the airport with the installation of a
digital radio platform and a digital radio system.
Since then all users, including all ground operations staff and airlines, have
drawn on a single radio platform for every possible communication process ?
and according to the airport, it has brought about a major improvement in
operational efficiency.
The applied system includes a flight-oriented dialling application to enable
immediate communication among every person involved in aircraft turnarounds
at the gate.
Another part of the system is the security guard control. All guards use a
portable device to swipe a radio-frequency identification tag at pre-defined
control points on their patrol routes. This ensures that security personnel follow
their routes and alerts supervisors of any problems or deviations.
“We believe that these types of new mobile and wireless technologies will
change the way airports operate in the future.”
The third feature of the solution is the passenger emergency call, which
provides calls from the Sky Train, a monorail connection that operates between
the terminals of Düsseldorf International and the nearby railway station.
According to SITA, this ensures reliable communication and fire alarm signals
from the train in the event of an emergency.
Speaking at the launch of the system at Düsseldorf International, Boris
Padovan, SITA’s regional vice-president of sales and relationship management
for East and Central Europe, said: “We believe that these types of new mobile
and wireless technologies will fundamentally change the way airports operate in
the future, by creating innovative, cost-effective services for airports, airlines
and passengers alike.”

The future has already started: in recent years, many airports have moved
towards wireless applications to replace aging infrastructure and out-of-date
communication systems. Increased security, increased competence when
handling mission-critical communications, airport-wide coverage, integrated
voice and data opportunities, and cost-effectiveness have made the change easy.

Airport terminals and buildings by HTS TENTIQ are engineered using an
aluminium frame. This combines lightweight, non-corrosive qualities with
strength and durability. It also makes the buildings quick and easy to
manufacture, transport and install.

Despite this, all buildings are engineered to meet site specific snow and wind
loadings, ensuring they can provide a more permanent solution if required and
remain in place for fifteen years plus.
The buildings will be designed to your exact specification, including
dimensions, insulation levels, roof systems, wall cladding, glazed panels, doors
and windows.
An airport building from HTS TENTIQ can also be supplied with all the
necessary equipment needed for a fully functioning terminal, including
temperature control, PA systems, video surveillance, baggage handling systems,
.counters, furniture, and fire detection
When would you need a temporary airport building?
Instead of a permanent building
Permanent building projects can be a drain on resources, especially time and
budget. As an alternative, a HTS TENTIQ semi-permanent airport terminal
building means you can achieve the same result as a permanent structure but for
much less time, cost and headache.
Seasonality and events
Unforeseen peaks in seasonality or a large global event could mean existing
airport facilities can no longer cope with the increase in passengers. In turn this
might cause frustration and delays. In the case of a high-profile world summit or
event, having the right transport infrastructure in place might be key to the
event’s overall success. This additional space can be easily provided with a
HTS TENTIQ airport building or terminal, creating the space needed for the
exact time period required.
Fire or flood damage
Fire or flood damage can cause chaos at any airport, with passenger and cargo
flights drastically reduced. The ability to have the airport operating at full
capacity quickly is essential, and something that can be achieved by using a
HTS TENTIQ airport building.
Improvements and Refurbishments
A structural or aesthetic improvement to existing airport buildings and facilities
can affect operational capacity. To avoid this, a temporary airport building from
HTS TENTIQ can be provided for the duration of the work.

What I learned about communication at the airport

Airports have always been a very comical experience for me, and it is
guaranteed that I will have acquired a great story during my journey.
There are many opportunities for verbal and non-verbal exchanges
between people at the airport whether it is waiting in the security line,
waiting to board the plane, or during the actual flight itself. Depending
on the duration I will either quietly sit back to people watch, or I will reach
out to start a conversation with the person next to me. There are three
particularly memorable experiences that have provided me valuable
lessons about communication.
1. Several years ago as I waited to board my plane I sat watching the
arriving/departing planes, when I overheard the conversation a
man was having on his cellphone with a colleague. He made a
comment that was relatable to me at the time. He said “if I ask
someone to do something, I expect them to get it done.” I sat
there and thought about my team and how I frequently had to
follow up on tasks multiple times and essentially micro-manage. I
really wanted to be the screaming fan in the stands, at a popular
sporting event, putting my fist in the air while yelling “yeah!”
because I completely understood his frustrations. Having read the
book “First Break all the Rules” I now have a different perspective.
As leaders/managers, it is our responsibility to assess whether or
not an employee is in the right role and if he/she has the proper
 tools/resources to fulfil their tasks. When we communicate our
expectations are we also ensuring the person is set up for
success?

2. A second memorable encounter I had at the airport occurred in

security line. I walked through the body scanner and was pulled to
the side by a TSA representative. She told me I had to get my
palms scanned, at the time I was unsure why they had to scan my
palms, so I obliged. I was cleared to gather my belongings and
proceed to my gate. As I walked towards the boarding gate, with a
colleague, a man who was walking towards me described my
expression as priceless when I had to have my palms scanned.
My colleague and I looked at each other perplexed, because we
did not see him anywhere near the security area. We assumed
that he must have been up in a separate room watching through a
video camera. In case you are wandering it was only later that
evening, when talking to my husband, that I learned they were
searching my palms for drugs. Apparently I displayed suspicious
behavior when I patted my pockets to ensure I removed everything
before going through the scanner. How does this relate to
communication? There are ears and eyes everywhere, and we
need to be mindful of this in the workplace. The things we say and
do can all leave lasting impressions with our employees, whether
good or bad. We need to be careful that any form of
communication is delivered in the most proper way at all times.
 3. The third memorable encounter was when I was traveling back
from Charleston, SC from a conference. The conference was
incredible and I met so many great people. During the flight home,
I sat with a client so we could talk during our short one-hour flight.
About half way through the flight I started sharing the experience I
had when learning about the DISC personality assessment (see
my blog from a few weeks ago). The older woman to my left
interrupted me to let me know that I was too loud and disturbing
her reading. She appeared very irritated, and proceeded to turn
her attention towards the window so she could continue reading.
For the remainder of the flight I softened my voice, while thinking
that maybe she needed a lesson on personalities. Sometimes the
way in which we communicate can have unintended
consequences. It is important to understand the intended
audience of your communication and the respective surroundings,
so the message is received as intended. If the message is
unwelcome, additional consideration needs to be given as to the
approach used.
Effective communication is so critical and must be handled in a way that
leaves people with a feeling of transparency and honesty. Do you need
to better understand your employees, do you need to be more aware of
your surroundings, do you need to alter your communication method,
etc.? These are all questions to reflect on, especially if someone is
struggling to understand the message you are trying to convey.
