What are the advantages of Lora?
Sep 26, 2018

1---greatly improves the sensitivity of the receiver and reduces the power consumption. The link budget of up to 157db makes it possible to communicate distances up to 15 km (environment-related).

Its receiving current is only 10mA, sleep current 200nA, which greatly delayed the battery life.

2---The gateway/concentrator based on this technology supports parallel processing of multi-channel multi-data rate and large system capacity. A gateway is a bridge between a node and an IP network (via 2G/3G/4G or Ethernet). Each gateway can handle communication between nodes 5 million times per day (assuming a 10Bytes, network occupancy rate of 10% per delivery).

If the gateway is installed in the location of the existing mobile communication base station, transmitting power 20dBm (100mW), then in the building dense urban environment can cover about 2 km, and in the lower density of the suburbs, covering a range of up to 10 km.


3---The system based on the terminal and Concentrator/gateway can support ranging and positioning. Lora measurement of distances is based on signal-to-air transmission time rather than traditional rssi (Received Signal sterngth ind-ication), while positioning is based on a multipoint (gateway) measurement of the air transmission timing of a point (node). Its positioning accuracy is up to 5m (assuming a range of 10km).
