Which of the following frequency bands is NOT typically used in wireless communication?

The correct choice indicates that the GHF band is not recognized as a standard frequency band utilized in wireless communication. In wireless communication, frequency bands are categorized into specific ranges based on their wavelength and applications.

VHF (Very High Frequency), LF (Low Frequency), and SHF (Super High Frequency) are all established frequency bands used in various wireless communication technologies. VHF is used for FM radio and television broadcasts, LF is commonly associated with navigation and AM radio, while SHF is widely applied in microwave communication, radar, and satellite communications.

In contrast, GHF (Gigahertz Frequency) is not a formally defined frequency band in the context of wireless communication standards. While the term might sound plausible and could imply frequencies in the gigahertz range, there is no recognized band specifically labeled as GHF in standard wireless communication practices. Hence, this makes it the correct response to the question regarding which frequency band is not typically used.
