Does anyone know how much data one of these receivers will use per day or month?
I ask because I want to place one in a remote mountain radio shack and will be using a WiFi hotspot for data.
Hard to say what yours will use specifically because it is highly based on the amount of aircraft traffic in your area but it can be anywhere from 3 to about 10GB per month. You can cut that down a bit by turning off MLAT and there are other tweaks you can do to cut down how often stat is sent. There are remote areas it has been tweaked down to work over 64kbps cellular connections.
I would definitely suggest you join our discord server which is much more active than here and has a bunch of knowledgeable people who can help you get it working.
