To: Federal Communications Commission 7435 Oakland Mills Road Columbia, Maryland 21046 Subject: FCC 15.203 Compliance, Non-Standard Antenna Connector Requirement Gentlemen, The Nortel Networks access point radios are available in versions that incorporate only internal antennas as well as a version that incorporates antenna connectors for connection to external antennas. FCC ID: RVW2230 Model 2230 FCC ID: RVW2231 Model 2231 IC: 332R-2230 Model 2230 IC 332R-2231 Model 2231 These connectors used in these models are “Reverse TNC” connectors and are currently FCC 15.203 compliant. Additionally, it is Nortel’s intent that these IEEE 802.11 access point radios be professionally installed and NOT installed by the end user of the system. If you have any questions, please do not hesitate to contact me at: [email protected] or (408) 832-7053 Sincerely, David Waitt Consultant representing Nortel Networks

4655 Great America Parkway Santa Clara, California 95054 www.nortelnetworks.com To: Mr. Tim Johnson, American TCB From: David Waitt Subject: IEEE802.11 B/G access point A/B/G up-grade process Date: 25 Mar 2004 This letter outlines the procedure that will be followed to allow upgrade of the IEEE802.11 B/G access point to an IEEE802.11 A/B/G access point. If there are any questions or if additional information is required, please contact me at [email protected] On behalf of Alcatel, David Waitt Upgrading from 802.11 B/G to 802.11 A/B/G This grant is for an 802.11 B/G radio. It is possible to upgrade the radio to a dual band 802.11 A /B /G radio by installing an additional 802.11 card in the open slot within the radio. Alcatel understands the FCC concerns regarding “User Upgrades”. In order to assure that the Alcatel radios remain compliant after an upgrade from 802.11 B/G to 802.11 A/B/G and has been performed correctly, Alcatel will handle upgrades in the following manner. Alcatel has negotiated contracts with different contractors qualified to install and perform the upgrade. Alcatel has instructed the contractors on how to properly perform the upgrade. Once the process is complete, the contractor is then placed on an “Alcatel Approved List” of upgrade contractors. The end user (typically an IT department) of the Alcatel access point will then be instructed that in order for the Alcatel 802.11 network to remain FCC compliant, any “multi-band” upgrade effort must be performed by one of the Alcatel qualified contractors in their area. The upgrade process consists of two basic steps: 1: Installing the module: To preclude the opening of the access door by someone other than the trained professional responsible for upgrading/maintaining the system, Alcatel has elected to secure the access door with “Security hardware” that can only be removed using very specialized tools not available at local hardware stores. It should be noted that removal of the access door only allows access to the various connectors to allow installation of an 802.11A card. It does NOT allow access to the antennas inside the device. The contractor opens the radio via the access door and simply installs an 802.11 module in the “A” slot of the radio. Connect the internal coax cables to the module and re-install the access door. 2: Re-labeling the device: The installer will then re-label the device over the previous FCC ID label to indicate the correct FCC ID for the newly upgraded device.

To: Federal Communications Commission Industrie Canada From: Nortel Networks Subject: Justification for Class A classification of the following FCC IDs FCC ID: RVW2230 RVW2231 IC: 332R-2230 332R-2231 Date: 5 March 2004 Gentlemen, The purpose of this letter is to provide justification for classifying the above products as Class A. All of the devices are similar IEEE802.11 access points with the exception that they are either A/B/G or B/G radios as indicated by their FCC ID.

To: Federal Communications Commission Industrie Canada From: Nortel Networks Subject: Theory Of Operations FCC: RVW2231 IC: 332R-2231 Date: 11 Mar 2004 Gentlemen, Below is a brief explanation of the operation of the Nortel access point Radio The Nortel radio is an IEEE 802.11 B/G Access point (AP) intended to be professionally installed and configured in corporate and industrial environments. The access point is powered either by an external 48V power supply or via power over Ethernet. The device utilizes a mini PCI module manufactured by an outside vendor. The modules incorporated into the Omni Access Point radio are IEEE802.11 A/B/G mini PCI modules. However the functionality of the module is determined by the mini PCI slot in which the module is inserted. (See internal photos) The device does not include a “Turbo” mode. INTERNAL ANTENNA VERSION The AP utilizes integral antennas on the 802.11 B/G band. The access point effectively includes only a single 2.4GHz patch antenna, however, there are actually two 2.4 GHz antennas internal to the access point chassis. The module switches rapidly between the two antennas and when a signal is detected, the access point uses the antenna offering the best transmission characteristics. At any one time, there is only one antenna connected to the internal PCI module. The effective gain of the 2.4 GHz internal antenna path (the antenna switch and the antenna itself) is 6.8dBi. The diagrams below outline the RF path from the output of the mini PCI module to the integral antennas within the access point. In the internal antenna version shown below, the software prohibits the switching of the FET antenna switches. 2.4 GHz RF Block Diagram (Internal Antenna Version) 802.11 mini PCI module Antenna Diversity FET Switch Approx -1dB Trace Internal Patch Antennas, 7.8 dBi Each Trace Net effective 2.4 GHz antenna gain: 6.8 dBi Primary Output Aux Output FET Switch Approx -1dB INTERNAL/EXTERNAL ANTENNA VERSION Additionally, there is a version of the access point which allows connection of external antennas. When External antennas are connected to the access point, the configuration software switches the internal antenna switches into the EXT position. The antenna diversity functionality described earlier works in the same manor for the external antennas. The external antennas used with the access point must be “patch” type antennas and have a net effective gain (antenna gain - cable loss) equal to 6.8 dBi or less. At any one time, ONLY the internal or external antennas may be selected. It is NOT possible to configure the access point to rapidly toggle between external and internal antennas. The only difference between the internal only version and the internal / external version of the access point is the addition of a small coax cable to an external 15.203 compliant antenna connector in the chassis. 2.4 GHz RF Block Diagram (Internal / External Antenna Version) Additionally, the device has been tested for compliance to the FCC Part 15 Class A limits. A report has been prepared and is on file at Nortel Inc. If any further information is required, please do not hesitate to contact me at the email address below.
