It is very different per situation. We always test with line of sight and we get more than 100m but that is in Alberta where the humidity is very low. A lot of stuff has effect on the range like walls, antenna, stuff close by, etc. The link budget for devices with the Nrf52 is about 100dBm (-96 sensitivity and +4 output power). We have a number customer that uses the mcMod120 for outdoor asset tracking to see if the asset is in a restricted place. It is beacon based so more information is received and it requires only one way communication.
Our new gateway has +20dBm output power. This does not solve everything because the devices are still sending at +4dBm but the gateway also has two antenna's for better antenna diversity.
Our new mcMod120LR also sends at +20dBm and has been tested up to 1KM line of sight. In practice it will not reach that but it will operate much better in a ware-houses and other restricted indoor environment. All software is 100% compatible between the devices. It will be powered by 2 AA batteries.

Engineering samples will be available within a few weeks
