The system has an output power of around 125 W operating in the 10-10.25 GHz band.

The device uses the 5.8 GHz band for wireless transmission.

They broadcast the pre-wimax 802.11a signal on the 5.7 GHz band in a 1.5 mile radius.

The 5 GHz band was even known as the "common carrier" band.

The 2.4 GHz band is a general use band.

The 5 GHz band can solve some of these problems, but it introduces others.

WiFi takes up five channels of the 2.4 GHz band.

Microwave ovens operate by emitting a very high power signal in the 2.4 GHz band.

Older devices have poor shielding, and often emit a very "dirty" signal over the entire 2.4 GHz band.

Like 802.11b, 802.11g devices suffer interference from other products operating in the 2.4 GHz band, for example wireless keyboards.
