In the IoT world, the LoRa communication protocol is seen as the holy grail because it comes to solve many challenges, like ensuring high-density connectivity for large-scale architecture sensors.
With the innovations & surprising
outcomes of the LoRaWAN technology, we have jumped a step ahead on the ladder
of Growth & Developments. Undoubtedly, the three C’s plays a crucial role
over the years, in the stream.
Connect: First C is for “Connect”. It
means how we can integrate the external world to the digital world. And the
answer is “Sensors”. Through Sensors we can capture the data from the external
world & forward it to the next C.
Control: Second C is for “Control”.
The data from the Sensors then collected & processed through the
Microcontroller & Microprocessor which is the controlling unit here &
sends it to the Cloud. All the control programming logic is written in the tiny
small chip.
Communicate: The third C is to
“Communicate”. We need to communicate the data to the User. Hence the data will
then be communicated over the cloud to monitor & control from anywhere in
the world. HTTP, MQTT are some of the communication protocols.
Among all these steps, the first &
foremost C is contributed through LoRa Module. These LoRa modules are the base of IoT.
These are secure, regulatory-certified, programmable, low-power RF modules,
providing long-range, low bit rate IoT data connectivity to sensors and
actuators.
These
LoRa Modules allow harnessing the power of Data to streamline the operations. They're
LoRaWAN compliant, providing bi-directional data communication up to 10 miles
line-of-sight and 2-3 miles in buildings, using the global sub-GHz frequencies.
The
LoRa Module complies with three LoRaWAN classes that operate simultaneously.
Class A is purely asynchronous. There is a delay between
the end of the uplink transmission and the start of the receive window. If the LoRa
Network Server does not respond during these two receive windows, the next
downlink will be after the next uplink transmission. Hence, it is low power
LoRa module.
Class B systems work with battery-powered nodes. Every 128
seconds, the gateway transmits a signal called beacons. All LoRaWAN base
stations simultaneously transmit signal/beacon messages at one pulse-per-second
(1PPS). All Class B nodes are assigned a time slot within the 128-second cycle
and are told when to listen to the packet coming.
LoRa System, for instance, indicates to the server when end device can listen. Hence it allows for a downlink message to be transmitted.
Class C allows nodes that can
receive downlink messages all the time except in transmit mode. So, it is ideal
for the applications requiring more downlink transmissions. Hence, we can say
that Class C devices are always in listening mode. This system is used
primarily for AC-powered applications because it consumes a lot of energy to
keep a node/module constantly running.
The LoRa
Module is designed to plan, optimize, and simulate real-world scenarios
ensuring a robust network that covers all devices and meets performance
requirements. Concluded that LoRa wireless technology has significant role in
the IoT market. The Interconnecting devices
are utilized to create smart cities, industrial and commercial solutions, while
reducing the limitations from other wireless technologies such as power and
other overheads.
The
Internet of Things (IoT) is thus termed as a revolutionary technological
advancement that can dramatically change the way we live, work, and play..
