TRUNKED RADIO SYSTEM WITH DEMAND-CONTROLLED BROADBAND NETWORK EXPANSION

摘要

The trunked radio system (10) according to the invention comprises a trunked radio network (12) having narrowband transmission channels (17) with high area coverage and a wireless data network (13) with broadband transmission channels (27), the wireless data network (13) having incomplete area coverage. If, when necessary, a trunked radio terminal (22) requests expansion of the area coverage of the wireless data network (13) via the trunked radio network (12), in order to expand the wireless data network at least one mobile converter device (55) is positioned such that the location of the requesting trunked radio terminal (22) is reached with the wireless data network (13).
