Unlicensed National Information Infrastructure - regulations for UNII devices operating in the 5.15 to 5.35 GHz and 5.725 to 5.825 GHz frequency bands.

Unlicensed National Information Infrastructure. UNII band refers to license-exempt frequency band in the 5 GHz range. 802.11a wireless LAN standard operates at this frequency band to avoid interference as in the crowded ISM band. But the higher the frequency, the shorter the distance it can cover. Also see ISM band.

Unlicensed National Information Infrastructure. An FCC regulatory domain for 5-GHz wireless devices. UNII bands are 100 MHz wide and divided into four channels when using 802.11a OFDM modulation.

Unlicensed radio bands that operate at 5.2GHz.

The Unlicensed National Information Infrastructure radio band is part of the radio frequency spectrum used by IEEE-802.11a devices and by many wireless ISPs.
