Explain UHF Band in detail?
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range
between 300 MHz and 3 GHz, also known as the decimeter band as the wavelengths
range from one meter to one decimeter. Radio waves with frequencies above the UHF
band fall into the SHF (super-high frequency) or microwave frequency range. Lower
frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio
waves propagate mainly by line of sight; they are blocked by hills and large buildings
although the transmission through building walls is high enough for indoor reception.
They are used for television broadcasting, cell phones, satellite communication
including GPS, personal radio services including WiFi and Bluetooth, walkies-
talkies, cordless phones, and numerous other applications.
