B5CH118AA Product Manual
DRU-E 5 GHz WLAN Radio Module
Page 3 of 17
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.

Conditions of Use
General Conditions of Use
This manual is intended to supplement training provided by Ericsson or
authorized parties. The module B5CH118AA is only intended for use in Ericsson
products and is not for sale to the general public as a stand-alone module.
Please read this entire document, including the Regulatory Statements section
before attempting to install or operate the module.
Warning: Any use of B5CH118AA in any manner which is not expressly specified
within this manual or specifically approved by Ericsson or its authorized agents will
void the user’s right to opera te this module, and is expressly forbidden by Ericsson.
This includes any modification of the module, installation of the module in a
configuration or used with antennas which are not expressly listed in this document
or approved by Ericsson.

Country of Use
B5CH118AA is certified with limited modular approval for use as an Intentional
Radiator in the United States as device: FCC ID: RAR5000500 1 and in Canada as
IC: 4674A-50005001. Please read all regulatory statements at the end of this
document before any attempt to ins tall or operate this module.
The module is only certified for operation in the United States and Can ada. Before
attempting to install and operate this module in any other country, contact
Ericsson for approval.
Module Labeling
One or more labels are applied to the module during manufacture, including a
label which identifies the FCC and Industry Canada identification numbers. Do not
attempt to remove any labels from the module.
Module Installation and Service
Installation into a Product
The module shall only be installed by a technician trained by Ericsson or its
authorized agents. It should only be installed into an approved product (see
above) following all manufacturing and service procedures for that product. The
module should only be installed into a final product in a manufacturing or service
depot site.
Caution: B5CH118AA is an electro-static discharge (ESD) sensitive device. All
appropriate ESD measures must be taken when handling the module. Failure to
employ appropriate ESD protection may damage the modul e.
Module Service
The module is not intended as a field-serviceable unit. It contains no fieldreplaceable or field-serviceable parts, or any external adjustable mechanisms. The
module should only be serviced in a manufacturing or service depot site approved
by Ericsson or its authorized agents.
