WHAT THE KIT DOES
The phone is the interface. J25 is the local radio layer.
Use familiar controls
Operate PTT, text and voice messages, offline maps and supported team-location functions from the phone.
Communicate through LoRa
J25 terminals exchange local team information without relying on cellular data for the local radio path.
Use a participating path
Where configuration and field placement allow it, participating J25 nodes can provide an additional mesh path.
RANGE · READ WITH TEST CONDITIONS
Distance depends on the route, not only the radio.
ChatField reports an ideal communication distance of up to 10 km in open terrain such as plains, open line-of-sight routes or areas with limited hills, and around 5 km in urban conditions with high-rise buildings and structural obstructions. Buildings, dense urban obstructions, terrain, interference, antenna position and node placement can reduce usable distance.
