THE CORE OF LORAWAN:®LORA MODULES
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 & Development. 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 into the digital world. And the answer is “Sensors”. Through Sensors, we can capture the data from the outer world & forward it to the next C.
Control: Second C is for “Control”. The data from the Sensors are 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 on a 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 and 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, that provide long-range, low-bit rate IoT data connectivity to sensors and actuators.
These LoRa Modules allow harnessing the power of Data to streamline 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: It 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 subsequent downlink will be after the next uplink transmission. Hence, it is a low-power LoRa module.
- Class B: Systems work with battery-powered nodes. Every 128 seconds, the gateway transmits a signal called a beacon. 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.
- Class C: Allows nodes that can receive downlink messages simultaneously except in transmit mode. So, it is ideal for 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 a significant role in the IoT market. The Interconnecting devices are utilized to create smart cities, and industrial and commercial solutions while reducing the limitations of other wireless technologies such as power and other overheads.
The Internet of Things (IoT) is thus termed a revolutionary technological advancement that can dramatically change the way we live, work, and play.
