Montreal-based Radio IP Software Inc. has inked an agreement with Motorola Inc. to jointly develop and deliver next-generation products for the terrestrial trunked radio (TETRA) community. The systems under development will enable trunked radio users to add more data applications onto the Motorola’s Dimetra IP TETRA network system.  The Radio IP software allows users to combine a variety of wireless network protocols including HSDPA, WiFi, WiMAX and others to their existing Dimetra network and terminals, while at that same time maintain a continuous, reliable secure connection.
