Which frequency range corresponds to Ultra High Frequency (UHF)?

The frequency range that corresponds to Ultra High Frequency (UHF) is 300 to 3,000 MHz. UHF is part of the electromagnetic spectrum and is used primarily for television broadcasting, mobile phones, satellite communication, and various forms of two-way radio communications.

Understanding the classification of frequency bands helps in identifying the specific applications and characteristics associated with each range. UHF is known for its ability to penetrate building materials better than higher frequency bands, which makes it suitable for urban communication. It also has favorable propagation characteristics for line-of-sight communication, making it effective for mobile and handheld devices.

In contrast, other frequency ranges listed either fall well below or above the UHF category. For instance, the range of 30 - 300 GHz refers to millimeter waves, which are used in advanced communication technologies but are not categorized as UHF. Similarly, the range of 3 - 30 MHz is categorized as Medium Frequency (MF) and is typically utilized for AM radio broadcasts, while the 3 - 30 GHz range refers to Super High Frequency (SHF), which encompasses microwave communication and satellite transmissions.
