Definition
(Context: General)
Designated by the FCC to provide short-range, high-speed wireless networking communication at low cost. U-NII consists of three frequency bands of 100 MHz each in the 5 GHz band: 5.15-5.25GHz (for indoor use only), 5.25-5.35 GHz and 5.725-5.825GHz. The three frequency bands were set aside by the FCC in 1997 to help schools connect to the Internet without the need for hard wiring (Adapted from Wi-Fi Planet).
