Airaya American Telecommunications Certification Body, Inc. 6731 Whittier Avenue Suite C110 McLean, VA 22101 October 5, 2002 Dear Examiner: I am writing to avoid the possibility of an inadvertent disclosure of proprietary information. The accompanying Form 731 is being filed with the commission on our behalf by Elliott Laboratories, Inc., a consulting and testing laboratory. Included as exhibits with the enclosed application are block diagrams, schematics, both detailed descriptions of the theory of operation of the device from Atheros and Airaya, and the test report R#48540. It is our intention to provide the commission with a full disclosure of our product so that its merits can be evaluated. Indeed, we are pleased to provide any further information that the commission might wish to see. It is not our intention, however, to make our proprietary process a matter of public record. In view of the fact that the block diagrams, schematics, and associated theory of operations disclose the mechanism of our process, we ask that these portions (block diagrams, schematics, and theory of operations) of our application be withheld from public inspection as provided under FCC section 0.459. These documents contain details of the proprietary operation of product. These details are not readily discernible - even to technically sophisticated individuals - from our hardware and constitute trade secrets. We request therefore that these documents and this letter be segregated from the body of our evaluation report and withheld from public inspection. Thank you for your attention. Please let the undersigned know if the Commission disagrees with our position or requires further justification. Sincerely, William G. Pabst Vice President, Engineering AIRAYA

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 11, 2002 RE: FCC ID: QED-AI108 Attention: Juan Martinez I have a few comments on this Application. 1 Your summary of results states antenna(s) of 18 and 24dBi. Page 8 of the report states 18 and 21dBi as antenna gain and on page 31 it states 24dBi gain. The theory of operations also states 18 and 24dBi. Please note that the reference to using a maximum power out of 250mW (24dBm) + 6dBi antenna or 30dBm total, should be the guide for maximum power given any specific antenna. This means that with an output as measured at 10.9dBm the maximum gain antenna would be 19.1dBi. The 18dBi antenna meets this requirement. For a maximum power of 8.9dBm, the maximum antenna gain would be 21dBi. As mentioned above, your report section “Antenna Requirements” states 21dBi antenna. However, your summary of results and other documentation states 24Bi (3 dB higher than allowed). Please correct the report and/or all other documentation to be consistent about the maximum antenna(s) used and tested. Alternately, please retest your device to show a maximum power of 5.9dBm using a 24dBi antenna. xxx 2 FYI no response needed. Please note, 15.407(b)(2) states, “For transmitters operating in the 5.25-5.35 GHz band: all emissions outside of the 5.15-5.35 GHz band shall not exceed an EIRP of -27 dBm/MHz. Devices operating in the 5.25-5.35 GHz band that generate emissions in the 5.15-5.25 GHz band must meet all applicable technical requirements for operation in the 5.15-5.25 GHz band (including indoor use) or alternatively meet an out-of-band emission EIRP limit of -27 dBm/MHz in the 5.15-5.25 GHz band.” This is not an either or statement and applies to both indoor and outdoor systems. This means that the –27dBm limit outside the 5.15 to 5.35 band applies to both inside and outside use. It also means that any emission in the 5.15-5.25 GHz band, regardless is indoor or outdoor use, must meet the technical requirements for that band or must –27dBm limit in the 5.15-5.25 GHz band. xxx 3 Please note that as of September 9, 2002 conducted emissions for Part 15 devices is 150kHz to 30MHz. Your report states 450kHz to 30MHz. Please also note that the 13dB relaxation no longer applies under the new rules since an average limit now exists. Your report conflicts with test data. The data states you used EN55022/CISPR22 while the above states you use FCC limits. Please correct your report to be consistent as to what test was done. xxx 4 In one part of the report, it appears to state that the device is capable of indoor and outdoor use. In another part of the report, it states that the device is indoor use only. Please correct the documentation (all) to be consistent with the intent of the device as tested. xxx 5 In one part of the documentation and report you state that only integral non accessible antenna(s) are used. In other documentation, it states external detachable antenna(s) are used. In other documentation, you state profession installation. Your summary of results also declares the antenna(s) tested are detachable type and yet the report is only for internal integral antenna(s). The photos appear to show the external portion of the system is the transmitter connected to the ‘internal’ portion of the system via RJ45 cable. Is the reference to ‘external antenna’ simply meaning that part of the system which includes the transmitter that is outside. And if so, are the antenna(s) internal to the outside box. On the other hand, does it mean something else? Please clarify antenna usage in all documentation to agree on the type, and purpose of this device as tested. Please provide evidence that the antenna(s) used with this device meet the definition of ‘integral’ as tested. Please clarify your definition of internal and external as pertains to this device and its antenna(s). xxx l Page 2October 11, 2002 6 Your report is not clear as to what type of power measurements were made. Please clarify in the power measurements beginning at page 34 of the report are conducted or other. xxx 7 The manuals say the AI108 is a Class A device, yet the label on the AI108 is for Class B. This is in violation of the rules for DoC of Part 25 devices. Please correct and clarify as needed. xxx Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

Page 1 of 3 RE: FCC ID: QED-AI108 Attention: Dennis Ward Date: October 18 th 2002 In response to your comments raised on October 10 th , 2002 regarding this Application, please find my answers below: 1 Your summary of results states antenna(s) of 18 and 24dBi. Page 8 of the report states 18 and 21dBi as antenna gain and on page 31 it states 24dBi gain. The theory of operations also states 18 and 24dBi. Please note that the reference to using a maximum power out of 250mW (24dBm) + 6dBi antenna or 30dBm total, should be the guide for maximum power given any specific antenna. This means that with an output as measured at 10.9dBm the maximum gain antenna would be 19.1dBi. The 18dBi antenna meets this requirement. For a maximum power of 8.9dBm, the maximum antenna gain would be 21dBi. As mentioned above, your report section “Antenna Requirements” states 21dBi antenna. However, your summary of results and other documentation states 24Bi (3 dB higher than allowed). Please correct the report and/or all other documentation to be consistent about the maximum antenna(s) used and tested. Alternately, please retest your device to show a maximum power of 5.9dBm using a 24dBi antenna. The antennas to be used have maximum gains of 18dBi and 24dBi. The RF output level at the antenna connector for the 18dBi antenna is 10.9dBm. The RF output level at the connector for the 24dBi is 8.9dBm, but the actual power delivered to the antenna is reduced by 3dB (using either an internal 3dB attenuator or via the use of a length of cable for external antennas with a loss of at least 3dB at 5.27GHz) to meet the FCC output power limitation. This statement can be found on the revised report page 5 of 18, Professional Installer guide page 29 of 29, and Theory of Operation page 1 of 4. The test report and test data have been revised to be consistent in the description of the antenna gains and to clarify the output power measurement. The “Professional Installation Manual” and the “Theory of Operations” have both been revised to describe the use of the attenuator or cable to ensure compliance with the EIRP limitations. 2 FYI no response needed. Please note, 15.407(b)(2) states, “For transmitters operating in the 5.25-5.35 GHz band: all emissions outside of the 5.15-5.35 GHz band shall not exceed an EIRP of -27 dBm/MHz.

It also means that any emission in the 5.15-5.25 GHz band, regardless is indoor or outdoor use, must meet the technical requirements for that band or must – 27dBm limit in the 5.15-5.25 GHz band. Noted, thanks. 3 Please note that as of September 9, 2002 conducted emissions for Part 15 devices is 150kHz to 30MHz. Your report states 450kHz to 30MHz. Please also note that the 13dB relaxation no longer applies under the new rules since an average limit now exists. Your report conflicts with test data. The data states you used EN55022/CISPR22 while the above states you use FCC limits. Please correct your report to be consistent as to what test was done. The report has been corrected to reflect the new limits and frequency range for conducted emissions tests. 4 In one part of the report, it appears to state that the device is capable of indoor and outdoor use. In another part of the report, it states that the device is indoor use only. Please correct the documentation (all) to be consistent with the intent of the device as tested. The EUT is primarily intended for outdoor use. The report has been revised to remove any confusion. 5 In one part of the documentation and report you state that only integral non accessible antenna(s) are used. In other documentation, it states external detachable antenna(s) are used. In other documentation, you state profession installation. Your summary of results also declares the antenna(s) tested are detachable type and yet the report is only for internal integral antenna(s). The photos appear to show the external portion of the system is the transmitter connected to the ‘internal’ portion of the system via RJ45 cable.

On the other hand, does it mean something else? Please clarify antenna usage in all documentation to agree on the type, and purpose of this device as tested. Please provide evidence that the antenna(s) used with this device meet the definition of ‘integral’ as tested. Please clarify your definition of internal and external as pertains to this device and its antenna(s). The EUT has two antennas coax connectors for attaching either 1 or 2 antennas to the device. The operation of the hardware prevents the unit from transmitting on both antenna connectors at the same time. This is located on the Theory of Operation page 2 of 4 For certain applications only one antenna connector will be used to provide a connection to an antenna. When one antenna is connected to the EUT, it can be mounted on the EUT or used externally with an N connector through the enclosure. When two antennas are connected to the EUT, one antenna will be mounted to the device and the other connected externally via an N connector attached through the enclosure. The two types of antennas available for the system are 18dBi or 24dBi. All configurations that use an external antenna are supplied via a professional installer of the system, thereby allowing the use of the “standard” N connector. Configurations that only use the internally mounted a…

These installations require a trained installer to insure the operation of the unit is correct and meets the requirements of the FCC and Industry Canada (IC). We believe that the product has a very specific set of applications that make having the external N-type a necessity. For instance, in extreme cold weather conditions, the electronics of the radio unit will need to be sheltered from the elements to prevent its operating temperature from being sustained below 0 degrees for any length of time. An external cabling system will allow for this. With no active components in the antennas, the antenna can be mounted in the extreme elements, allowing the unit to operate normally while the radio unit is protected from the elements. In addition, as antenna technology improves, costs drop, and new antenna suppliers enter the market, we believe that this version of the product will allow us the flexibility needed to meet new requirements for these types of products and unforeseen user requirements. Any new antenna that will be used, inside the US and Canada, with this version of the product, will be tested and a permissive change submitted for approval before release to our Professional Installers. Before a qualified reseller/professional installer is allowed to purchase an external N-type connector version of this product, the reseller will 637 Adair Court ● Morgan Hill, CA ● 95037 Tel: 866-224-7292 ● Fax: 408-776-9583 certify that the unit will be used only with currently approved antenna’s for the AIRAYA AI108 product family with only a cable connected between the primary radio unit and the antenna. All qualified resellers in the US and Canada will sign an affidavit, agreeing, that any configuration of the AIRAYA AI108 with an external N-type connector, sold by them, will only be attached to an approved antenna for this version of the product. The reseller will provide the necessary Professional Installation to the end user guaranteeing that the unit does not exceed the output power requirements of the US and Canada. Also, the reseller and the Professional Installer will be responsible for guaranteeing that the end user has an FCC and IC approved configuration of the product. Training for the reseller and Professional Installer will be provided by AIRAYA. These training sessions will include the latest information on acceptable (approved) antenna’s for the AI108, path and the use of the encrypted access to on-board firmware. Sincerely, William G.
