The role of the Base Station is to act as an internet gateway for the local LoRa network. It uses a Telstra 3G connection (850MHz band) to upload LoRa data to the web. Each Base Station can have up to 200 LoRa Nodes within its range, reporting on an hourly basis. Proper installation of the Base Stations is critical for maximising performance of the system.
The Base Stations come with a capped 50MB monthly plan by default. Once the monthly data allowance is exhausted, it will stop forwarding LoRa messages until the start of the next monthly period (this will not necessarily fall on the 1st of the month). The Base Stations need to be externally powered using either the provided AC/DC 12V power pack or the optional solar energy kit.
By default, the Base Stations comes with a high performance Cellular antenna and a 1/4 wave whip LoRa antenna which will deliver high performance over very long distances. To extend the range further it is possible to remove the antenna provided and replace it with a high gain SMA antenna mounted on a mast (not provided)
