Ultra High Frequency (UHF) refers to a range of radio frequencies from 300 MHz to 3 GHz. This frequency band is commonly used for television broadcasting, mobile phones, and two-way radios. UHF signals can carry more data and provide better sound quality compared to lower frequencies, making them ideal for modern communication systems. UHF waves have shorter wavelengths, which allows them to transmit signals over shorter distances. However, they can penetrate buildings and obstacles better than higher frequencies, making them useful in urban environments. Devices like Wi-Fi routers and GPS also utilize UHF frequencies for effective communication.
