INTRODUCTION
EXITING TECHNOLOGIES AND DRAWBACKS
PRINCIPLE OF LORA TECHNOLOGY
Features OF LORA AND APPLICATIONS
CONCLUSION
INTRODUCTION
• LoRa stands for Long Range Radio and is mainly targeted for
M2M and IoT networks.
• This technology will enable public or multi-tenant networks to
connect a number of applications running on the same network.
• LoRa is a new found technology that is emerging rapidly.
• The LoRa technology addresses needs of a battery operated
embedded device. The LoRa technology is a long range low
power technology
EXISTING TECHNOLOY AND
DRAWBACKS
• Bluetooth and wifi have short range
covrage
• Cost of wifi module is high
• Wi fi consume more power
Principle of lora
Fig. architecture of LORA
The LoRa network consist of four basic elements
The LoRa node or End Points The Network Server
Application Server The Gateway
The LoRa Node or End Points
• The end points or LoRa nodes comprises sensors or application where sensing and control
takes place such as sensors, tracking devices, etc.
• This is the heart of an embedded system. These include water meter, smoke alarm, gas
monitoring and such application sensors, tracking devices, etc.
• This is the heart of an embedded system. These include water meter, smoke alarm, gas
monitoring and such applications
The Gateway
• The gateway comprises the net element of the LoRa network. There are a
number of gateways . Each gateway is connected to every end node.
• The data transmitted by the node is sent to all the gateways and each
gateway which receives a signal transmits it to a cloud based network server
via cellular, Ethernet, satellite, or Wi-Fi.
The network server
• The network server has all the intelligence. The data received from different gateways
is filtered, security checks, adaptive data rates etc., are performed and
acknowledgement is sent to the gateways
• The network server is the one who identifies whether the data received is intended for
any application server and is thus sent to the intended application server via some
backhaul.
The Application Server
• They receive the intended data from the network
server.
Feature of lora
A. Long Range of Lora :
As the name implies LoRa is a long-range protocol. It is capable of transmitting
data over long distances. A single gateway can cover hundred-kilometer square
of area.
B. Battery lifetime
The low battery consumption in a LoRa networks accounts to the asynchronous
communication of the nodes in the network. In a LoRa network the nodes
communicates only when they have any data to send whether energy driven or
scheduled. They adopt the ALOHA method.
C. Network Capacity
Star network is used in Lora network. The LoRa network gateway receives data
from large number of nodes. For this the gateway must have high capacity.
APPLICATION OF LORA
A. LoRa for street light monitoring
• LoRa technology can be used for street light automation. The given block
diagram can be implemented for the automation of streetlight using LoRa
module.
• The whole system optimizes the power consumption and is very easy to install.
B. LoRa for smart parking
• The LoRa sensor can detect if the parking place is full and notify the driver who
is looking for a parking spot.
• This can significantly reduce the time to search for a place because the driver
can be notified beforehand about the availability of space
CONCLUSION
• LoRa or LPWA is a very recent technology that has been evolved. In 2013 or
before that, the term did not even exist. Now the technology has developed
and is being promoted and used worldwide because of its various technical
advantages.
• This technology that an application uses depends on its requirement and other
factors. it is a preferred and most suited technology for the IoT applications
that need to communicate a long distance and in which the battery lifetime
and power consumption is a major limitation.
• LoRa technology also offers high security. It is expected that by 2024 3.6
billion LPWA connections will be established.
