Shows and Events Radio Systems Marketing Participated

RSM introduced several new features to the Mobilcom van, most notably a fully operational Software Defined Radio. Visitors were invited to bring any radio they had, public safety, family radio system, citizen's band, anything that operated between 1 and 1,200 MHz. Their radios were quickly "sniffed" by a special application in the Software Defined Radio and they were immediately patched to talkgroups established on the van's own 50, 150, 450 and 800 MHz radio systems which were fully operational. Multi-party interoperable radio communications were demonstrated to hundreds of visitors.

Visitors were invited to bring any radio they had in any band between 1 MHz and 1,200 MHz, and they were immediately connected to radios in the bands of 50, 150, 450 and 800 MHz using a Software Defined radio

The Software Defined Radio was a pre-production unit, it could simultaneously emulate up to three radios on trhee separate frequency bands.(Production units emulate and can crosspatch nine radios simultaneously) It was built on a Desktop PC platform and was controlled from the keyboard and display console on the left side

RSM obtained permission to place its own Mobilcom van at the entrance of the downtown hotel where PSWN was being held. There were numerous visitors from Local, State and Federal agencies visiting the Mobilcom van and testing the various ground and satellite Public Safety radios and interoperable communications systems on-board. RSM had installed and also demonstrated to several agencies a just launched new high speed 1xRTT Wireless Internet service from Verizon, which provides download speeds of up to 153 Kb/s.

The van was parked outside the Marriot Hotel on the Willamette River watefront, facing East. The rooftop antennas are Inmarsat M-4 64 Kb/s portable terminals that were connected to the Inmarsat AOR-W Satellite with an elevation of just a few degrees above the horizon, nearby buildings prevented a connection to another Inmarsat satellite with higher elevation.

The van was also connected to what was then the only high speed wireless internet access in the West Coast, the Verizon Express Network 1xRTT system operating at speeds of up to 100 Kb/s real throughput.

Radio Systems Marketing introduced a vehicular add-on interoperable kit to provide voice and data communications between different agencies, using Public Safety radios, wireless Local Area Networks, public wireless Internet access and satellite communications. The system demonstrated live voice, data and video communications, including Voice Over IP hand-held radio/phones at RSM's booth in the show.
