The M21 is Tech Series with a Myriad of IO options, and GPS tracking capability.

Raveon’s RV-M21  Tech Series radio modems are industrial-grade, high-speed, data radios designed for telemetry, SCADA, AVL, wireless data, mobile-data and remote control applications.

The Optional internal GPS ( GX option) enables the M21G to transmit its position, data, and status (voltage, speed, heading, temperature, I/O bits.) a pre-set intervals using either conventional carrier-sense methods or with efficient TDMA channel access. A GPS tracking system built with M21G transceivers, can track up to 20 radios with one-second updates or 200 with 10-second updated. The M21 is the fastest most efficient UHF AVL radio available. See details on its GPS tracking and TDMA abilities.
Designed by Raveon for long-range reliable communication using high-performance RF circuitry, up to 5 watts RF power output.
Filters for reliable data communications up to 19.2k bps on a 25kHz channel, 9.6k bps on a 12.5kHz channel., or 4.8k on 6.25k channel. It is feature-rich.

M21 Radio Bands and (Modem Module Used)

  • VHF Narrow band RV-M22S-VB   IF bandwidth: 6.25kHz, 12kHz, 25kHz,  RF Power: 1-5Watts  (RV-M8 OEM modem)
  • UHF Narrow band RV-M22S-UC   IF bandwidth: 6.25kHz, 12kHz, 25kHz,  RF Power: 1-5Watts  (RV-M8 OEM modem)

GPS Antenna Connects in the Back

A GPS tracking system built with transceivers, can track up to 20 radios with one-second updates or 200 with 10-second updated.
The M21 is the fastest most efficient UHF AVL radio available. See details on its GPS tracking and TDMA abilities.
The M21 is Tech Series with a Myriad of IO options, and GPS tracking capability. We have a great new GPS chip that is reliable.
Now there are many GPS features.

M21 GPS IS Popular and Long Range

Raveon built GPS with transceivers, to track up to Many radios. Our GPS radios have been used by many systems.

SCHOOL-BUSSES have used our GPS radios to track BUSSES and monitor Doors to see if it is correct.

US ARMY used our GPS radios to keep people safe. It monitored Vibration, Temperature, and Alert Buttons of a Soldier needed help.

US MILITARY used our GPS radios to monitor Airplanes and see location and speeds and temperatures.

RACE SPEEDs used our GPS radio to monitor Racing Cars. Monitors location, speed, and collisions and failures.

And Raveon has great Engineering, so any GPS features you need Changed or Added, we can do this for your system.
