What is LoRa?
LoRa (Long Range) is a LPWAN (Low Power Wide Area Network) based technology. It is a wireless WAN that allows long-range data transmission at a low bit rate and at low power.
Really long. 2 to 5 km long. And that’s just in urban areas. The technology has a range of 5 km to a whopping 15 km in rural areas. And with a direct line of sight, it goes above even that!

How does it work?

The network is built on 4 major components: the end node, gateway, network server, and application server.

End nodes transmit data to nearby gateways, which further transmit it to the network server.
Network server selects gateway with best reception and forwards data to appropriate application server.
End user processes sensor data at the application server. Application server may send a response to the end node.
LoRa Gateways form the bridge between devices and The Things Network.

Why LoRa?

LoRa is the basis of the Internet of Things, which refers to a network of physical devices connected to the internet and can communicate with each other. Smart Homes, Logistics and Some examples of LoRa technology usage are:

Health and Hygiene

Temperature and Humidity monitoring, Smart wearable devices, Patient trackers

Upgraded Utilities

Monitoring of Water, Electricity, Fuel, Waste level


Smart Lighting, Radioactivity Measurement


Tracking Animals, Monitoring crop growing conditions
