Since our LYNX.sc Installation and Maintenance manual covers the whole spread spectrum LYNX.sc product line, these changes applies to the product manual submitted for this application as well. Please find in the attached an updated page of page 3-22 for section 3.10. Please use this page to replace the same page of the submitted manual.

Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 May 3, 2000 RE:Response to FCC Requests Correspondence Reference Numbers: 12911 FCC IDs: HZB-S24-08 Form 731 Confirmation Numbers: EA96599 Attn:Errol Chang Dear Mr. Chang: This is in response to your request 12911 regarding the application of HZB-S24-08 product. In our product manual, we recommend antennas to be used with our equipment by their size and gain. At 2.4GHz band, we recommend 2’ panel antennas and 2’-8’ parabolic antennas. The gains of these antennas range from 27dBi to 33.5dBi. As examples, we recommend to our users some typical antenna vendors now in the market, such Gabriel, Radio Waves, Andrew, Comsat, etc. Though of different make, antennas of the same dimensions have very similar gains and other specifications. The gains of antennas of various sizes are as in the following table. Antenna Type and SizeRange of Mid Band Gain for Antennas by Various Vendors (dBi) 2’ flat panel21.7 2’ parabolic20.6-21.6 4’ parabolic26.6-27.6 6’ parabolic30.1-31.1 8’ parabolic31.8-33.6 We believe as long as the antennas are consistent in their technical specifications, the differences in brand name, model number, and type should not cause discernable differences in radiated emission and RF exposure. We hope when grant conditions are necessary, these conditions will be made in the form of specifications (for example, size, gain range, or EIRP) rather than in the form of model names and vendors. I hope I have addressed questions in your request. Please contact the undersigned should there be any further questions.

Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 July 5, 2000 RE:Response to FCC Requests Correspondence Reference Numbers: 13858, 14162 FCC IDs: HZB-S24-08 Form 731 Confirmation Numbers: EA96599 Attn:Errol Chang Dear Mr. Chang: This is in response to your request 13858 and 14162 regarding the application of HZB-S24-08 product. 1. The antenna used during testing was a 4-foot grid antenna, Comsat RSI Mark part number P- 24A48G. The gain listed in the report is 27.7 dBi. Please find in attachment 1 the specifications of the antenna. At the time of equipment testing, we were not aware that our equipment needs to be tested separately with a panel antenna. Prior to that point in time, we were able to certify equipment for a range of panel and parabolic antennas by testing with the 4’ grid antenna only. It was not until more recently that the Commission has imposed additional antenna testing on our products. Given the timing of this testing, we request that the Commission permit the use of panel antennas up to 2’ in size without additional testing. Note that the 2’ flat panel antenna specifications are by no means worse in any respect than that of the 4’ parabolic antenna that was used during testing. 2. We request that the HZB-S24-08 radio be allowed to operate with up to 8’ antennas. There are several needs/benefits of using a higher gain antenna. First, a higher gain antenna has narrower beamwidth, which allows better frequency reuse and less interference. Also, in situations of considerable RF cable loss, additional antenna gain may be needed to compensate the cable loss. Occasionally, there are cases where a customer already has antennas of this size in use, and we like to allow them to use these existing antennas. We feel that these customers should be able to take advantage of the existing antennas by using the radio under a reduced output power, rather than having to invest in new antennas. We recognize the fact that the radio was tested with a 4’ antenna of 27.7 dBi gain. We suggest that the best solution is for the Commission to limit the EIRP for this system to that of the tested EIRP of 50.5 dBm. We will include information in our manual to instruct the customers how to properly adjust the output power to ensure that the tested EIRP is not exceeded. Please see in the attachment 2 for the information we shall include in page 3-19 of the manual. Please note, that even with 8’ antennas, in some cases where there is considerable cable loss, the tested EIRP will not be reached and the narrow beamwidth of the antenna is considerably beneficial to spectrum sharing. 1196 Borregas Ave., Sunnyvale, CA 94089-1302, USA Tel: +1 (408) 542-5200,Fax: +1 (408) 542-5300 3.

Yours truly Caroline Yu International Product Manager Western Multiplex Corporation INSTALLATION AND MAINTENANCE MANUAL LYNX.sc E1 FAMILY SPREAD SPECTRUM RADIOS SEPTEMBER 1999 SECTION 3: INSTALLATION & ADJUSTMENTSPAGE 3-39 3.13.1 Output Power Adjustment The LYNX.sc radio requires professional installation. In certain cases, it is necessary to adjust the output power from the factory setting, for example: vto meet EIRP (effective isotropic radiated power) limits, such as +6 dBW in Canada. vto meet transmitter output limits in the 2.4 GHz band for USA installations. vto avoid exceeding the maximum far-end RSL of 0 dBm. vto coordinate a hub or repeater location. To ensure maximum protection of the radio circuits, always ensure the antenna connector is terminated when power is applied. For precise measurement of transmitter power, a calibrated RF power meter (such as the HP 435B with Power Sensor HP8481) is recommended. This power sensor can be connected directly to the output of the radio without exceeding the power rating. With some power meters, it may be necessary to place a calibrated in-line fixed attenuator between the radio antenna port and the power meter so as to not exceed the power meter’s maximum input level. Thruline power meters do not operate at LYNX.sc RF frequencies. If adjusting the output power to meet an EIRP limit, it will be first necessary to calculate the overall system gains and losses, including feeder losses for the type of transmission line installed and the antenna gain. Also refer to Table 3-C or 3-D for transmitter output power settings where installed with various transmission line lengths and antenna sizes. You may determine the radio transmit power for EIRP limited installations by the following equation: Tx Power (dBm) = EIRP Limit(dBm) + Feeder Loss(dB) - Antenna Gain(dB) In the USA, 2.4 GHz models have an output limit which is determined by: Tx Power (dBm) = 30 - [(Antenna Gain - 6)/ 3] + Feeder Loss (Note: For the LYNX.sc2 4xE1 model, the transmit power should be the lesser of Tx Power as calculated above or [50.3-Antenna Gain + Feeder Loss] ) Output power may be adjusted using a small screwdriver and rotating the potentiometer which is recessed behind the front panel. Clockwise rotation increases output power while counter-clockwise rotation decreases output power. In lieu of a calibrated RF power meter, the PWR test port voltage can be used to estimate the output power. Figures 3-16 & 3-17 illustrate the voltage reading for vario…

Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Attention: Reviewing Engineer The HZB-S24-08 (MODEL 31350) radio is a full duty-cycle product exclusively designed for fixed-mount point-to-point applications (Please refer to Page 1-1 of the Installation and Maintenance Manual ). Each radio’s inputs are connected to external equipment through the radio’s interfaces. The RF output port is connected to a RF cable or a waveguide, which connects on the other side to an antenna usually installed on top of a building or a tower. It is impossible to use the radio in any mobile application. The HZB-S24-08 (MODEL 31350) radios need to be professionally installed outdoor either on top of a tower or a tall building. The installation sites are inaccessible to the general public. Only installation engineers may get close to the radio antenna during system installation. For the safety concern of the professional installers, we put a warning message on Page 3-22 of the product manual recommending installers stay at least 5 meters away from the antenna during system operation. The maximum output power allowed for the 2.4GHz spread spectrum radios is 1W, and the biggest antenna to be used with our 2.4GHz radios is of 8’ diameter (33.5dB gain). The worst case EIRP is when the highest gain antenna is used: Maximum EIRP = 30 + 33.5 – (33.5-6)/3 = 54.3dBm (269W); The power density at 5 meters from an antenna is: S = EIRP/4 π R 2 = 0.9 W/m 2 = 0.09 mW/cm 2 < 1 mW/cm 2 Where: S = Power density R = distance to the center of radiation of the antenna In the cases of using 4’, 6’ and 8’ parabolic antennas, the near field power density is S nf = 16 η P/ π D 2 . The worst case of near-field power density is when the radio output at 1W, η =1, and the antenna diameter D=4ft. S nf ma x = 16 x1/ π (4x0.3048) 2 = = 3.4 W/m 2 = 0.34 mW/cm 2 <1 mW/cm 2 Where: S nf = maximum near –field power density P = power fed to the antenna η = aperture efficiency D = antenna diameter So in all the above-mentioned situations, the power density is compliant with the limit for General Population/ Uncontrolled Exposure as specified in rule 1.1310.
