The RV-M8S OEM data radio modem is designed for embedded OEM applications where long-range data communications is necessary. It is available in UHF, VHF frequency bands and the 216-220MHz frequency band.
It communicates with and has the features of Raveon’s M7 series of data radio modems, at a smaller size and better efficiency. Its small size, lower power consumption, 1/2W to 5W of RF output, and versatile digital interface makes it easy to integrate into your product. It has user-selectable protocols, either packet data or POCSAG paging data reception.
With fast over-the-air data rates and fast transmit-to-receive switching, Raveon’s M8 data radio transceiver works exceptionally well in telemetry systems, polled metering systems, and anywhere when fast response time is required. Included in each unit is advanced networking, encryption, error correction, and local and remote diagnostics.
Because it is built using rugged “single-board” construction, it is extremely reliable – and cost effective. With prices for radio transceivers starting below $250, in OEM quantities, the M8S is the most versatile and economical embedded data radio available. And its price will pleasantly surprise you.

This OEM data radio modem has incorporated many many advanced features and functions. This product may not be used for communicating with medical devices, controlling irrigation equipment with paging protocols, or tactical military applications.
This module is targeted for low-power, solar, and battery-powered applications. Exceptional DC power savings is accomplished by:
A. Advanced CPU. Using the latest CORTEX micro-processor, it uses half the DC power as the CPU in our M7 used while running twice as fast. And has twice the memory. This is one powerful little radio modem.
B. Digital I/O. The power-hungry RS232 I/O driver has been eliminated. The input and output voltage levels are 3.3V logic, as well as the serial I/O. This saves power and cost. USB I/O is also available.
C. Switching Regulators. Raveon designed custom DC/DC converters with low RF energy for this product. We used double shields, many ferrite beads, and a 3X the required filter capacitors to make sure the power is clean, and the efficiency is excellent.
D. Integrated Modem. Raveon data radio products use software-based modems, so there is no external modem IC chip drawing additional power.
The 20 pin interface connector on the front of the board is the Universal OEM Wireless Connector (UWORC). This application note: AN224(UWORC) describes Universal Wireless OEM Radio Connector (UWORC) used on Raveon’s OEM data radio modems.
In this website, see the 20 pin UWORC info in: UWORK Connector Info
t is available in VHF, UHF, and 220Mhz bands. The 220MHz band is often used for Positive Train Control, and around the world 220MHz is popular in industrial communications. VHF and UHF commercial bands are usable in most all countries.
