B2CH079AA Product Manual – ERM2, 5 GHz WLAN Radio Module
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.

number BMA000281-A
Warning: Use of this module in conjunction with any antenna not expressly
listed above will void authority to install or operate this equipment.
Warning: Setting of module transmit power above the limits specified in the
above table for a particular combination of antenna type, frequency of operation,
and type of usage, will exceed FCC or Industry Canada limits and void authority to
install or operate this equipment.
Product Installation
Products which contain B2CH079AA-A shall only be installed by professional
installers trained by BelAir Networks or its authorized agents. In addition to normal
installation procedures and good installation practice, professional installers are
responsible to ensure that:
1. Only an approved antenna (see above) is connected to the module, and,
2. The antenna is mounted in such a manner and in such a location that access to the
antenna by the general population is minimized. Access to the antenna by the
general population should be limited to more than the minimum safety distance.
This distances are outlined according to product type and whether high gain
antennas are used:

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions (1) this device may not cause
harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
FCC Interference Statement
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
November 2007 Page 11 of 14
PM-B2CH079AA Version 2
B2CH079AA Product Manual – ERM2, 5 GHz WLAN Radio Module
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Manufacturer’s Industry Canada Conformity Statement
This device has been designed to operate with an antenna having a maximum gain of
30 dB. Antenna having a higher gain is strictly prohibited per regulations of Industry
Canada. The required antenna impedance is 50 ohms.
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference
that may cause undesired operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (EIRP) is not
more than that required for successful communication.
This Class B Digital apparatus meets all the requirements of the Canadian
Interference-Causing Equipment Regulations.
RF Exposure Statement
This Wireless LAN radio device has been evaluated under FCC Bulletin OET 65C
and found to be compliant to the requirements set forth in CFR 47 Sections 2.1091,
2.1093, and 15.247 (b) (4) addressing RF exposure from radio frequency devices.
This device complies with FCC RF radiation exposure limits for an uncontrolled
environment. The radiated output power of this Wireless LAN device is below the
FCC radio frequency exposure limits. However, this device should still be installed

and used in such a manner that the potential for human contact during normal
operation is minimized. In order to comply with RF exposure limits established in
the ANSI C95.1 standard, this equipment should be installed and operated at a
minimum distance between the radiator and a human body. This minimum distance
is:
