5 GHz radio supporting the 802.11a standard – The 802.11a standard is an
extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in
the 5-GHz band. The 802.11a standard uses an orthogonal frequency division
multiplexing encoding scheme, rather than Frequency-Hopping Spread Spectrum
(FHSS) or Direct-Sequence Spread Spectrum (DSSS).
2.4 GHz radio supporting the 802.11b/g standards – The 802.11g standard
applies to wireless LANs and specifies a transmission rate of 54 Mbps. The
802.11b (High Rate) standard is an extension to 802.11 that specifies a
transmission rate of 11 Mbps. Since 802.11g uses the same communication
frequency range as 802.11b (2.4 GHz), 802.11g devices can co-exist with
802.11b devices on the same network.
The radios are enabled or disabled through the HiPath Wireless Assistant. Both
radios can be enabled to offer service simultaneously. For more information, see
Section 7.3, “Topology for a VNS”, on page 168.
The Unlicensed National Information Infrastructure (U-NII) bands are three
frequency bands of 100 MHz each in the 5 GHz band, designated for short-range,
high-speed, wireless networking communication.
The Wireless AP supports the full range of 802.11a:
• 5.15 to 5.25 GHz – U-NII Low Band
• 5.25 to 5.35 GHz – U-NII Middle Band
• 5.725 to 5.825 GHz – U-NII High Band

Outdoor APs to walls, rails, and poles.
The HiPath Wireless Outdoor AP supports the 802.11a, 802.11g, and full
backward compatibility with legacy 802.11b devices.
