It is intended as a supplement to training and documentation by BelAir Networks Inc. or its authorized agents. RAR20005004 Product Manual – 5 GHz WLAN Radio Module Page 3 of 12 Introduction The RAR20005004 (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 device. 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.

1 December 15, 2006 Attn: Reviewing Engineer Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 RE: LIMITED MODULAR APPROVAL FOR FCC ID: RAR20005004 AS PER FCC PUBLIC NOTICE DA 00-1407 To Whom It May Concern, The module FCC ID: RAR20005004 is submitted for Limited Modular Approval (LMA) by BelAir Networks Inc. In keeping with FCC Public Notice DA 00-1407, Part 15 Unlicensed Modular Transmitter Approval, this letter affirms that BelAir Networks shall retain complete control over the final installation of the device and ensure compliance of the end-product to FCC regulations. The module shall only be installed into a final product by technicians trained by BelAir Networks. The module shall not be distributed, marketed or sold to the general public. It will only be available installed in a complete BelAir Networks BelAir200 product. The complete BelAir product shall only be sold by BelAir Networks directly or through a BelAir Networks-specified sales channel to authorized resellers, and will be installed by professional installers with training by BelAir Networks or authorized representatives. As illustrated by the accompanying documentation, the module FCC ID: RAR20005004 is a module with its own RF shielding, contains the complete radio within the module, provides its own power supply regulation, will be labeled with FCC ID, meets RF exposure regulations, and was tested in a representative enclosure for use in the BelAir200 product. The following is a point-by-point response to the items listed in DA 00- 1407: 1. The module has its own RF shielding. It has been tested for radiated emissions with the module in a representative package for the product in which it will be sold (BelAir200). BelAir Networks U.S. East 11921 Freedom Drive Suite 550 Reston, VA USA 20190 703-736-8306 BelAir Networks U.S. West 1902 Wright Place Suite 200 Carlsbad, CA USA 92008 760-918-5544 [email protected] BelAir Networks Inc. 603 March Road Kanata, Ontario Canada K2K 2M5 613-254-7070 [email protected] www.belairnetworks.com 2 2. The input to the module is an Ethernet interface. All modulation and 802.11 protocol elements reside within the module. There are no modulation or data inputs to the module which could alter the performance or behaviour of the modulator or radio which could cause it to exceed FCC limits. 3. The module has its own power supply filtering and regulation for all modulation and radio circuitry in order to avoid any issues with varying power supply inputs. The module is powered by several DC voltage rails. In order to test power line conducted requirements for the module, it was tested with the power supply and package as intended for the complete product which will be manufactured by BelAir Networks. BelAir Networks maintains complete control of the AC-to-DC power supply and packaging of the complete product and therefore ensures that compliance will be maintained. 4. The module incorporates MCX RF connectors and does not have an integral antenna on the module. The module was tested in conjunction with the intended antennas (see accompanying documentation). Considering our submission is seeking Limited Modular Approval, BelAir Networks will ensure professional installation of the complete product. In this manner we will ensure that only the approved antenna type is used in conjunction with this module. 5. The module was tested in an enclosure representative of the BelAir200 product. Since the module itself is not AC powered, power line conducted emissions were tested with the power supply and package in the configuration with which it will be installed in the product. This configuration is also tested to ensure the complete product will meet all Class B radiated and conducted emissions requirements. 6. The module will be labeled with its own FCC ID number. Since this label will not be visible when the module is installed in the complete product, the manual indicates that the final product shall include a permanent label which uses the wording “Contains FCC ID: RAR20005004”. See the labeling information provided with this submission. 7. The module operates under Part 15.247. Since all modulation and 802.11 protocol elements reside within the module, users will not have access to controls which may cause the module to BelAir Networks U.S. East 11921 Freedom Drive Suite 550 Reston, VA USA 20190 703-736-8306 BelAir Networks U.S. West 1902 Wright Place Suite 200 Carlsbad, CA USA BelAir Networks U.S. East 11921 Freedom Drive Suite 550 Reston, VA USA 20190 703-736-8306 BelAir Networks U.S. West 1902 Wright Place Suite 200 Carlsbad, CA USA 92008 760-918-5544 [email protected] BelAir Networks Inc. 603 March Road Kanata, Ontario Canada K2K 2M5 613-254-7070 [email protected] www.belairnetworks.com 3 operate outside its normal mode of operation. All timing and control for RF and modulator sections are inaccessible from outside the module. 8. The module has been evaluated with the intended antenna and complies with RF exposure requirements. The manual states the safety distance must be maintained between any person and the antenna. As BelAir Networks or its authorized agents will retain control of the final installation through the requirement for professional installation, BelAir Networks shall ensure that this distance is maintained in all installations. Sincerely, Marcel Chenier, Vice-President Engineering, BelAir Networks Inc.

RAR20005004 MPE Engineering Analysis Engineering Analysis MPE for 5 GHz Transceiver with Antenna Switch Module FCC ID: RAR20005004 BelAir Networks This analysis was performed as part of the FCC certification requirements for spread spectrum devices, according to the requirements of: FCC part 15, and FCC OET Bulletin 65 “Evaluating Compliance with FCC Guidelines for Human Exposure to Radio frequency Electromagnetic Fields”. • Module RAR20005004 will be mounted in BelAir Networks host units and will be professionally installed (Fixed) to provide a minimum separation distance from all persons as detailed in co-location compliance tables below. • Module RAR20005004 may be co-located with other modules in BelAir Networks products as shown in the co-location compliance tables below. Worst- case configurations are shown below. • This device will only be operated according to the exposure conditions described in this application. • End users and installers will be provided with antenna installation and transmitter operating conditions for satisfying RF exposure compliance. The measured worst-case transmit power yielding the worst-case EIRP were used for the MPE calculations. Calculations were performed based on FCC OET Bulletin 65. The calculations are performed based on the following formula provided in OET 65: S = EIRP / (4πR 2 ). Co-location compliance for multiple frequency exposure criteria to the power density exposure limit is detailed in the table below. This calculation is a worst-case analysis since it assumes all devices are continuously transmitting. The device utilizes the 802.11 WLAN protocol which operates in time-division duplex (TDD) mode, so the transmit duty cycle can never be 100% in normal operation. It is also assumed that all directional antennas are aligned to point in the same direction so that power from all radios add.
