November 2007 Page 4 of 14
PM-B2CH079AA Version 2
Introduction
The B2CH079AA (hereafter referred to as “the module”) is a 5 GHz radio module
compatible with the IEEE 802.11 standard for Wireless LAN operation. It is
designed to be interoperable with WLAN products which are based on Direct
Sequence Spread Spectrum (DSSS) radio technology.
The module contains a complete 802.11a radio and Medium Access Control (MAC)
protocol engine which allows implementation of an 802.11a module.
The module is not intended for stand-alone operation. It will only be marketed as a
complete product, in conjunction with a package, DC power supply and antenna
(hereafter referred to as “the product” or the “final product”).
Since the module has a BelAir networks proprietary digital interface, it cannot be
directly connected to any standard telecommunications or computer devices. It can
only be used with final products designed and authorized specifically for that
purpose.
