1) Long Range: LoRa devices can transmit signals over distances from 1km — 10km.
2) Low Power: LoRa end nodes wake up only at a fixed time, which can extend battery life. End node batteries can last for 5-10 years (Class A and Class B devices).
3) Security: data encryption using AES128 between end nodes and network servers/ Data encryption using AES128 at the application level.
4) Network Capability: single LoRa gateway device is designed to take care of thousands of end devices or nodes and easy to extend network capability by increasing gateways.
A LoRaWAN gateway capability is influenced by these factors:
• Tunnels: different tunnels can receive data from end nodes simultaneously; the greater quantity of tunnels, the more end nodes a gateway can connect to;
• Data size and reporting interval: large data size and reporting interval will reduce the end nodes that a gateway can connect to.
• ADR (Adaptive Data Rate): the distance between end nodes and gateways is closer, the data rate is higher, which can save the bandwidth of gateways.
5) Low Cost: work in free frequencies and no upfront licensing cost to use the technology.
6) Easy Deployment: simple network architecture and easy to deploy by yourself.
1) Not for large data transmission;
2) Not for continuous monitoring (except Class C devices);
3) Wake up only at a fixed time, so you can’t communicate with end nodes at any time (Class A and Class B devices);
4) The transmission rate is slow and easy to get interference because of using free frequencies.
