3004ML LoRa WAN datalogger utilises the LoRa communication system, LoRa WAN network, which utilises MQTT as its method of sending sensor data from the field to the Neon Server. The NRL LoRa operates in what Unidata calls LoRa Mode 2. In this mode, sensors are read by the logger according to the scheme. A set of short data packets will be sent, as set by logging interval, to the LoRa WAN gateway over either private or public LoRa network. LoRa WAN gateway transfers data packets to Neon Server using Ethernet, cellular or satellite network. The LoRa Wan system has a typical range of to 5 Km, the range reduces in built-up areas depending on building density and increases where there is a line of sight and with use of a larger antenna.
