M7 UHF Data Radio Products

RV-M7-U Data Radio Modems


Ultra High Frequencies (UHF) have been used for voice and data radio communications since the middle of the last century. Bands within the frequency range of 400-500MHz are used throughout the world for reliable communications. Raveon has wide-channel (25kHz) and narrow-channel (12.5kHz) versions. The RV-M7 data radio modem can be setup for 1- 5 watts for RF output.  It has built in modem, security, ID cods, and 100+ features. And lost cost.

In the USA, and in many other countries, the 450-512 MHz range is used for commercial wireless communications.

Raveon has UHF data radios in these bands:

A) 403-433MHz
B) 419-440MHz
C) 450-480MHz
D) 480-512MHz

UHF Radio Frequencies

The two major data radio modem bands used worldwide are the Very High Frequency (VHF) band and the Ultra High Frequency (UHF) band. Raveon provides data radio modems in both bands.

There is no one best band. VHF and UHF each have advantages and disadvantages to them. UHF has a shorter wave length, so the antennas are more compact and less obtrusive. VHF antenna are typically larger than UHF, but in many instances, the communication range will be greater with a VHF system. Raveon’s CE compliant UHF modem for use in the EU, is compatible with all other RV-M7 series modems.

In open areas, most users will find that VHF data radios communicate further then UHF data radios. But in heavily wooded areas, or rough terrain, UHF data radios may work better. UHF signals penetrate foliage better, and will reflect off of rock and other obstructions quite well. UHF will also work indoors a little better than VHF and it penetrates buildings better.

This is a list of many of the features in  Raveon’s data radio modems:

Application note AN125 M7 Competitive Features describes the features in Raveon’s RV-M7 modems.

  1. Backed by a 2-year warranty.
  2. A variety of frequency bands.
  3. Small and highly integrated, making it the most economical modem on the market.
  4. Outstanding receiver sensitivity, and with their programmable data rates, the user may select long-range and slower data or faster-data at reduced sensitivity.
  5. Dual-Mode.  Unique to the M7, it operates in either a Streaming or Packetized modes.
  6. Flexible I/O    The M7 has more I/O options than any other radio modem.
  7. Integrated Repeater. in Every Unit All M7 modems have integrated store-and-forward repeater capabilities in them.
  8. 16-bit Modem Addresses    The M7 modems in a system may be configured with a 16-bit address and network mask.
  9. Reliable Data     Raveon’s M7 incorporates 16-bit CRCs, and reverse error correction, so that all data that comes out of an M7 is 100% perfect.
  10. Common Port    Similar to all telco/Hayes type modems with the AT command set, the M7 uses a common serial port for operation, configuration, and diagnostics.
  11. Remote Ping    The M7 supports a variety of remote diagnostics, including a remote “Ping” command.
  12. Auto-Status Reporting   An M7 may be configured to automatically and periodically report its status over-the-air.
  13. TDMA Option   Al M7 modems have the option of being ordered with a unique TDMA (Time Division Multiple Access) feature. TDMA orchestrates the transmissions of an entire field of M7 modems to ensure that no two transmissions occur at the same time.
  14. WMX Communications  The Wireless Messaging Exchange protocol is an option to communicate with the radio and send data over the air. WMX features include specifying radio IDs, issuing commands, sending data, and monitoring RSSI.
