Which is a common use for the UHF frequency band?

The UHF (Ultra High Frequency) frequency band, which ranges from 300 MHz to 3 GHz, is widely used for television broadcasting. This is because UHF frequencies offer a good balance between coverage and resolution for television signals, allowing them to transmit high-definition video over considerable distances and penetrate obstacles effectively. UHF is particularly suitable for the transmission of digital television signals, which require the capacity to carry large amounts of data.

Television broadcasting in the UHF spectrum allows for several channels to fit into a relatively small bandwidth, accommodating multiple broadcast stations in a given geographic area. This is particularly useful in urban environments and areas with a high population density, where efficient use of frequency space is critical.

Other options, while related to wireless communication, do not typically fall under the primary uses of UHF frequencies. For instance, microwave ovens predominantly operate at a specific frequency of 2.45 GHz, which, although within the UHF range, is a specialized application. Satellite communication generally employs frequencies in the L-band, S-band, C-band, Ku-band, and Ka-band, which are distinct from the core UHF television band. Cellular networks operate across various frequencies, including UHF as well as others such as GSM, PCN, and
