What communication methods are used between sensors (Clipper, FlexR, TMV) and the Gateway Hub?

Communication between the Clipr, Flexr and TMV- sensors and the Gateway Hub is conducted via the LoRaWAN protocol. There are several protocols capable of sending small data packages over long distances using only battery power. Factorylab specializes in LoRaWAN.

Other known protocols are:
➢ LoRaWAN: a world standard wireless data (machine to machine) protocol. Open source, no license needed to broadcast
➢ Sigfox: like LoRaWAN but far less used
➢ NB-IoT: uses e-SIM technology. Ideal for sites with only a few (< 5 pcs) sensors. No need for a gateway but telecom companies charge relatively high fees (± £ 2 per sensor per month only for data)

Customers might expect some kind of Bluetooth or WiFi connectivity but we don’t use that. Bluetooth hasn’t got the range and WiFi needs plugging into a mains electrical connection.
