The IP501M LTE mobile PTT radio provides instantaneous wide-area communication using Icom’s CONNECT network. Users can make individual calls, group calls or all calls the same way as a conventional two-way radio. The IP501M does not require its own repeaters or IP network, which eliminates the costs of building and maintaining a wide area radio network. The mobile’s small size is perfect for vehicles with limited space. The IP501M also allows ethernet connectivity to interconnect with GPS software and other potential functionality in the future.
