UHF (Ultra High Frequency) is the Internation Telecommunications Union‘s designation for radio frequency identification in the range between 300 MHz and 3 GHz. The UHF frequency range is further allocated for various purposes that vary by geographical location (see the Wikipedia page for UHF for more information on UHF frequency allocations). UHF is used for television broadcasting, cell phones, GPS, Wi-Fi, Bluetooth, and RFID business applications that require longer read ranges than lower frequency bands can provide (think livestock tracking and race timing).
