VHF/TETRA/UHF/RFID

UHF and VHF stand for ultra-high frequency and very high frequency;
UHF radios work between 300 MHz and 3 GHz; they have shorter wavelengths that are better able to penetrate through steel and concrete, which makes them well-suited for indoor use. VHF radios broadcast between 30 MHz and 300 MHz, and are generally speaking more appropriate for outdoor use and areas of open terrain.

The VHF TETRA solution enhances TETRA’s accessibility for operations where long-distance coverage is crucial. VHF signals travel farther than UHF, whether above or below ground, providing a simpler and more cost-effective way to expand radio coverage in expansive rural outdoor areas or large underground environments.
