The TAA-50-220 Bus Telematics Transmitter provides a cost effective, spectrally efficient and reliable alternative to using PMR radios or retro-fitting legacy PMR radios with a data channel for the broadcast of bus information/telematics services on the Band III.

Applications include the broadcasting of messages containing bus identity and time of arrival for passenger information signs and the broadcasting priority messages for traffic light controllers.

In both of these roles the TAA offers the ultimate in performance with respect to spectral efficiency, unlike a PMR radio, it is able to operate at power levels even as low as ten milliwatts and has a key-on time measured in microseconds rather than tens of milliseconds.

Both of the aforementioned substantially reduce spectral pollution and hence the subsequent risks missing messages due to overlap clashing by factors as great as 200:1, prerequisite in guaranteeing the success of any city centre bus priority scheme.

We manufacture a range of professional radio modems called the rtcom. These include the Global which is approved to ETS 300 220, Australia Standards, FCC Part-90 and MPT1329. The other modems include the Universal which is approved to MPT 1340 and ETS 300 220. All products are EMC Class-1 certified to ETS-300-683. For long range, radio modem, radio communication links we have the Outback. This The Outback is available as both modems and telemetry systems. These modems are ideal for scanning telemetry and SCADA applications and are 100% MODBUS transparent.
