We are now selling the remarkable Talkpod A50P walkie-talkie.
It works well as a general-purpose UHF business radio, but it includes technology that allows a group of these radios to work together to create and ad-hoc "meshing" network, where radio calls are relayed from one radio to another automatically and seamlessly.
This can drastically increase the area of coverage of the whole group.
Each radio can "relay" radio messages on other Talkpod radios in the area.
