Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 February 17, 2000 RE:Re sponse to FCC Re que sts Correspondence Reference Numbe rs: 12038 FCC IDs: HZB-S58-25 Form 731 Confirmation Numbe rs: EA95966 Dear Mr. Dichoso 1. Please see attachment 1 for the latest version of section 3-10 of the Installation and Maintenance Manual. This warning was recommended by Greg Czumak on a similar product (HZB-S58-12) which just received FCC approval. The 5-meter distance is based on calculations in attachment 2. We are aware from a previous FCC request (#11532 regarding the HZB-S58-12) that the Commission is also looking at applying rule 1.1307 to our spread spectrum radios. Even though we still disagree with this approach of the Commission (please refer to my response to request 11532 on HZB-S58-12 in attachment 3), we are willing to lower the certified output power of HZB-S58-25 to 24.6dBm (290mW) to comply with the 1640W EIRP limit set in rule 1.1307. Please refer to attachment 3 for the supporting calculation. 2. Please see in attachment 4 for the confidentiality request letter. Please note that we only requested items listed in this letter to be held confidential. The other items were unintentionally marked as confidential while uploading the application. 3. Please find in attachment 5 the photo showing the component side of the RF board; the omission of this photo was unintentional. 4, 5Please find in attachment 6 a reply to your questions regarding processing gain. Greg Czumak raised a similar question recently when HZB-S58-12 was under review, which uses an identical spreading scheme. Grant for that product was awarded on Feb. 14, 2000. 6 For the flat panel antennas, we recommend only up to 2 foot in size. We did not mention this specifically because 2 foot is the biggest flat panel antenna available in the market. We will make modifications to the manual to be more specific about the antenna sizes to recommend only 1’, 2’ flat panel and 2’, 4’, 6’ and 8’ parabolic antennas for 5.8G spread spectrum radios. Please refer to Attachment 7 for a list of the antennas we recommend in the manual and the supporting technical specifications of the flat panel antennas from some typical manufacturers. As you can see, the maximum gain for the 2’ panel antenna is 28dBi, which is below the gain of the antenna used in testing. Therefore, at 5m distance and far field the radio will not introduce any RF exposure exceeding the level as calculated in attachment 2. As far as out-of-band emissions are concerned, the use of a 28dBi-panel antenna does not in anyway deteriorate the test results of the radio. Therefore, in addition to the 2’-8’ parabolic antennas, the 1’ and 2’ flat panel antennas should be allowed to be used with the HZB-S58-25 radios. I hope this response has addressed all your concerns and the grant for the HZB-S58-25 will be awarded soon.

Attachment 2RF exposure statement Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Attention: Reviewing Engineer The HZB-S58-25 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 applications. The HZB-S58-25 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 3-20 (section 3.10) of the product manual recommending installers stay at least 5 meters away from the antenna during system operation. The maximum output power tested for the HZB-S58-25 is 420 mW (+26.2 dBm), and the biggest antenna to be used with our 5.8 GHz radios is of 8’ diameter (41dB gain). Due to the fact that the HZB-S58-25 radio is used for fix-mount point-to-point communication that requires line-of –sight clearance in the path and that the radio is single-unit in-door equipment, the antenna sites are always far away from the radio equipment room. The typical length of RF cable that runs from the output of the radio to the antenna input is over 100 feet. In situations w here an antenna site is extremely far from the equipment room, waveguide may be used as a means to reduce the loss from RF transmission. A typical distance between antenna and radio when waveguide is used is over 200 feet. To give a worst example, let’s assume 100 feet Andrew 5/8” foam coax cable or 200 feet Andrew waveguide is used. Given 0.5dB loss for the connectors on each end, the loss introduced by RF cabling is at least 3.5-5.5 dB (please refer to the table below for Loss/100’ data). As for the majority of cases, the transmission line loss is usually in the range of over 10dB. When the transmission line loss is taken into consideration, the maximum possible EIRP will be: Maximum Output power + Maximum Antenna Gain – Minimum Implementation Loss = 26.2 + 41 – 3.5 = 63.7 dBm. the power density at 5 meters from an antenna is: S = EIRP/4 π R 2 = 7.5 W/m 2 = 0.75 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 2’, 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 the certified power, η =1, and the antenna diameter D=2 ft. S nf max = 16x0.42/ π (2x0.3048) 2 = = 5.7 W/m 2 = 0.57 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.

Attachment 3 1.FCC Request 11532 To: Ken Ruppel, Glenayre Western Multiplex From: Greg Czumak [email protected] FCC Application Processing Branch Re: FCC ID HZB-S58-12 Applicant: Glenayre Western Multiplex Correspondence Reference Number: 11532 731 Confirmation Number: EA95627 Date of Original E-Mail: 01/14/2000 1. We will need a list of all antennas to be used for this 5.8 GHz ss transmitter. 2. Your recent UNII filings had only 200 W EIRP output (due to 53 dBm limit for UNII). Even though the same type of antennas are proposed for the current filing, this device can have an output up to 2.7 kW EIRP when using a 41 dBi dish. This transmitter has an output nearly 10 times higher than the previous 2 UNII filings. Its output is also above the general categorical exclusion limits for routine RF exposure evaluation for licensed transmitters (see 1.1307 Table 1). Even through the rules do not specifically require a spread spectrum transmitter to perform routine RF exposure evaluation, because operations in the 5.8 GHz band do not have any EIRP restrictions for point-to-point operation, and there is a much higher potential for devices with high EIRP to exceed RF exposure requirements, we may need to apply 1.1307 (d), if there are no other effective solutions. The following are possible choices and/or issues which you may want to address or consider - (a) Tests for emission requirements have been based on a 29 dBi antenna. With RF exposure requirements in effect, we have concerns for approving antennas with gains higher than those tested, especially when the EIRP is substantially high. In this case, we may need to limit the maximum antenna gain to 29 dBi, as tested, in order to make it reasonable/acceptable for RF exposure compliance purposes. (b) Alternatively, you may choose to voluntarily limit the maximum EIRP (to similar levels used by your recent UNII filings) and we will indicated the maximum EIRP as a grant condition. This would allow you to consider antennas with higher than 29 dBi gain for this transmitter, with effective power reduction mechanisms. Again, a list of all antennas used by this transmitter must be submitted, including installation and power reduction procedures. (c) If both of the above options are not desirable, and you want to maintain the full 23.3 dBm output for antennas with higher than 29 dBi gain (the maximum EIRP is about 2700 W for the proposed 41 dBi gain antenna), we will need to consider the alternative in 1.1307(d), which may lead to an Environmental Assessment. This high EIRP is substantial, and is also above the general categorical exclusion limits of 1640 W EIRP for licensed transmitters, which typically have minimum antenna height requirements. This means that you may need to address environmental impact issues for RF exposure at all sites using this transmitter, including any antenna co-location issues for all sites (that generally also reduces the allowable limits for individual antennas since the total output of all antennas at the site is expected to be higher, see 1.1307(b)(3)). Please respond, informing us which of these options you select, or other alternatives you may propose, allowing us to complete the review of this application. Once an effective solution has been determined, we will determine the procedures for satisfying compliance and the type of antenna installation requirements, separation distances or any warnings etc.needed. The items indicated above must be submitted before processing can continue on the above referenced application.

The antennas must be highly directional, and the transmission path must have line-of-sight clearance. The radio antennas must be installed either on top of a tower or a very high building so that the line-of-sight condition can be met. Therefore, the antenna sites are not accessible to the general public. Installation of the radios and antennas must be performed by professional installation engineers. The transmission paths of the radios are well above ground level radiating in a beam point to point rather than omnidirectional to the gen…
