The 5 GHz band is also an unlicensed frequency range which has been used more for enterprise applications, controlled environments such as hospitals or government networks, and for timing critical applications. There are however some consumer applications that are beginning to adopt 5 GHz. In part this is due to the fact that it is far less crowded than the 2.4 GHz band, so performance is greater due to less interference. This band is also much larger than the 2.4 GHz band, so it has wide channel spacing and 20+ non-overlapping channels. There are some downsides however, one being that operating at a higher frequency can degrade the range of a device. Also, to operate in this band requires added hardware which can increase the device cost. Furthermore, the FCC regulates this band more strictly and radars are allowed to operated at this frequency which can cause interference.
