UHF radio modem

UHF Radio Modem

Ultra High Frequencies (UHF) radio modems have been used fordata radio communications since the middle of the last century. Bands withing the frequency range of 400-500MHz are used throughout the world for reliable communications. Initially, radio modems were made by combining telephone modem capability with a two-way voice radio, to make a radio modem. Although some companies today still take such an approach, Raveon's M7 series of UHF radio modems are the most highly integrated and cost effective UHF radio modems on the market.

In the USA, and in many other countries, the 450-512 MHz range is used for commercial wireless communications. Raveon has UHF radio modems in these bands:

A) 403 - 433MHz

B) 419 - 440MHz

C) 450 - 480MHz

D) 480 - 512MHz

 

UHF Radio Modem Frequencies

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

There is no one best band. VHF and UHF frequencies 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.

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