Description
SATELLINE-3AS VHF is a half-duplex VHF radio modem that
operates on 135 … 174 MHz or 218 … 238 MHz frequency band. Channel spacing 12.5
and 25 kHz are available, with over-the-air data rates of 9600 bps or 19200 bps,
respectively.
A special advantage of the VHF frequency band is the wider
coverage. With the same carrier power and antenna gain, the connection ranges
are 30 to 50 percent larger than those reached with an equivalent UHF radio
modem.
The radio modem is compatible with the most widely used serial interfaces RS-232, RS-485, and RS-422. The SATELLINE-3AS(d) VHF with 5 W output power and a heat sink is the appropriate choice when continuous transmission (when the transmitter duty cycle exceeds 20%) is required. In mobile fleet management applications, the use of VHF frequencies reduces signal fading significantly. A SATELLINE-3AS(d) VHF network consists of remotely adjustable radio modems controlled through the master station by the SATEL NMS (Network Management System) software. The SATEL NMS provides a powerful graphical tool for designing and monitoring the radio network.
