How Good is Lora Radio Technology?

The internet enables people to tackle routine tasks, communicate with others and provide remote services. But, very few people are aware of the fact that internet technologies are also designed for devices to communicate amongst themselves. LoRa is one of them. It allows electronic devices to interact with one another without human intervention. Interesting, isn’t it?

Let us explore more about LoRa Radio Technologies and their uses.

What is LoRa?

LoRa devices and networks enable smart IoT applications that help troubleshoot the challenges our planet faces, such as natural resource reduction, energy management, infrastructure efficiency, pollution control, and disaster prevention.

LoRa, or long-range, is a spread spectrum modulation technique derived from CSS or Chirp Spread Spectrum technology. LoRa is a long-range, low-power wireless communication protocol that has become one of the de-facto wireless low-power protocols of the IoT.

LoRa devices have garnered several use cases for smart homes, buildings, cities, communities, agriculture, metering, supply chain, logistics, and more. With millions of devices connected to networks in more than 100 countries, a smarter planet is what LoRa creates.

What is LoRa Radio Technology?

As a radio signal modulation technology, LoRa enables data exchange in IoT networks and becomes a foundation for private, public, and hybrid networks. A LoRa network provides broader coverage than cellular networks, where signals can travel up to 15 kilometers while consuming less energy. A LoRa network requires a central server, a base station (gateway), and endpoint devices to function properly.

The Endpoint devices observe metering equipment and provide telemetry. The Base stations accumulate data from endpoint devices and transfer them to the central server. The central server, named LoRaWAN Network Server (LNS), processes and stocks up the data obtained, and it handles the base station and endpoint device operation.

LoRa uses radio frequencies on the sub-gigahertz band. They are –

  • North America and Australia: 915 MHz
  • Asia: 923 MHz
  • Europe: 433 MHz, 868 MHz

These frequencies are license-free in most countries. Hence, all you require is the equipment to establish a LoRa network. The server gets connected with the LoRa gateway via an IP channel. The LoRa gateway communicates with endpoint devices through radio waves with spread-spectrum modulation. Two-way communication is secured amidst the endpoint devices and the gateway. One gateway can obtain data from numerous endpoint devices.

How is this LoRa technology used?

The LoRa protocol has multiple implementations in numerous fields. The technology allows the automation of monitoring, management, and control systems, simplifying their functioning. Here are a few ways LoRa technology is put to use –
