Introduction

The B5CH118AA (hereafter referred to as “the module”) is a 5 GHz radio module
compatible with the IEEE 802.11 standar d for Wireless LAN operation. It is designed
to be interoperable with WLAN products which are based on Orthogonal
Frequency Division Multiplexing (OF DM) radio technology.

The module contains a complete IEEE 802.11a/n radio and Medium Access Control
(MAC) protocol engine which allows implementation of an IEEE 802.11a/n access
point (AP).

The module is not intended for stan d-alone operation. It will only be marketed as a
complete prod uc t, in c onjunction with a package, DC power supply and antennas
(hereafter referred to as “the product” or the “final product”).

The module can be used in the 5 GHz U-NII / ISM bands.
Since the module has an Ericsson 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.
