The 15 GHz band, as defined by the ITU Radio Regulations ITU-R F.636, is a frequency band that falls within the microwave section of the electromagnetic spectrum. This band operates from 14.4 to 15.35 GHz and is specifically designated for fixed wireless systems, which are commonly used for broadband data transmission. The 15 GHz band is particularly advantageous due to its high frequency, which allows for the transmission of large amounts of data at high speeds. However, it also has a relatively short range and is more susceptible to atmospheric interference, such as rain fade. As such, it is typically used for short-range, line-of-sight applications, such as point-to-point links in telecommunications networks.
