EDGE series products are Internet of Things devices that speed up IoT project deployment on field sites in an easy and scalable way. There are two major wireless LPWA solutions: LoRaWANTM and LTE NB-IoT/Cat-M1 are deployed on the Edge nodes products respectively, fulfilling wireless monitoring and controlling needs under an IoT framework.
EDGE 2 conveniently and transparently connects the existing field site sensors/serial devices with only basic configuration to NB-IoT/Cat-M1 Internet network.
