Wireless Modem Card and Subsystem Overview The Cisco high-speed point-to-point broadband fixed wireless system provides a fixed, dedicated wireless link from one site to another. This link delivers full-duplex data in the licensed MMDS band (2.500 to 2.690 GHz), or unlicensed U-NII band (5.725 to 5.825 GHz). The broadband fixed wireless system consists of a Cisco uBR7200 series universal broadband router (Cisco uBR7246 or Cisco uBR7223) and one or more wireless modem cards (see Figure 1), each with a power feed panel (see Figure 2), and one or two wireless transverters (see Figure 3). (The diversity option, which minimizes the effects of fading, uses two wireless transverters, one for each of two antennas.) Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration 3 Wireless Modem Card and Subsystem Overview Final Review - Cisco Internal Use Only NoteThe wireless transverter discussed in this document is manufactured and sold by Cisco for MMDS links. Transverters for U-NII links must be purchased from third-party vendors. Refer to that vendor’s documentation for installation instructions. Figure 1Wireless Modem Card Figure 2Power Feed Panel Figure 3Cisco Wireless Transverter for the MMDS Band The wireless modem cards are installed in a Cisco uBR7200 series router. Each modem card is cabled to a power feed panel installed either in the same equipment rack as the router or mounted on a wall. Cables from the power feed panel are attached to one or two wireless transverters, which are installed on the antenna mast. The system is managed via a command-line interface (CLI) or CiscoView.

CokeniasEMC & Radio Type Approvals Test & Consulting Services for Commercial, Military, International Compliance P.O. Box 1086 El Granada, CA 94018 2 December Greg: Your questions and my responses Tom Re: FCC ID NTTSX1115 Applicant: Watkins Johnson Company Correspondence Reference Number: 10902 731 Confirmation Number: EA95108 Date of Original E-Mail: 12/02/1999 Please address the following questions (given that the maximum proposed EIRP is quite high, there is no way to avoid these issues). 1. The original antenna list has a 8 dBi antenna which has been changed to a 18.5 dBi antenna in the revised antenna list; please clarify if this is a replacement or addition. ANS: The flat panel antenna gain is 18.5 dB. The 8 dBi entry is a typo. 2. The MPE info has a 22 dBi antenna, the uploaded antenna list has a 23 dBi 1- ft dish (the closest match), please clarify which is the correct one. ANS: The Radio Waves model SP1-5.8 1 ft diameter antenna gain is 22 dBi. The 23 dBi entry is a typo. 3. There is no antenna or other info for the 14 dBi antenna (Mobile Mark, SCR 14-5723). Please upload appropriate antenna info, photo if applicable, and installation requirements for determining MPE compliance requirements. ANS: Information has been uploaded. See 14dBispec.pdf 4. The uploaded installation instructions and requirements are CISCO procedures for using this transceiver. Please provide Watkins Johnson's antenna installation procedures and requirements for non-CISCO operations. The applicant is proposing professional installation. Specific antenna installation procedures and requirements for the 5 (or 6) antennas proposed in this filing may be provided to the professional installers to ensure MPE compliance; if applicable, please upload a copy of the specific installation instructions. Instructions and/or warnings must indicate installer responsibility and identifying the purpose of installation requirements is for FCC RF exposure compliance. ANS: Please disregard the Cisco draft manual previously submitted. The Cisco manual currently addresses the MMDS ODU head and will require additional revisions to include page 2of 4 pages tel: 650-726-1263 fax: 650-726-1252 internet: [email protected] the UNII transceiver. Instead, please refer to the WJ draft, with modified page 7 amendment. 5. Please address the following and revise info and/or appropriate manuals and installation guides accordingly (both CISCO and Watkins Johnson if appropriate): (a) The filing, as indicated on the EAS, is requesting for 316 mW (25 dBm). The highest conducted output indicated in the MPE info is 27.8 dBm (603 mW). The maximum conducted output indicated in the WARNING statement in the CISCO installation manual is 33 dBi (should it be dBm ?), which is higher than those requested and measured. ANS: Please disregard the Cisco draft manual previously submitted. The Cisco manual currently addresses the MMDS ODU head and will require additional revisions to include the UNII transceiver The 33 dBm output refers to the MMDS band and is not applicable to this UNII product. Maximum power for the UNII 6 MHz channel is 24.8 dBm, and for 12 MHz channels the maximum allowed power is 27.8 dBm. Please update the 731 form for NTTSX1115 to state 27.8 dBm, or 603 mW, as the maximum power output from this product. (b) The antenna gain and separation distance for compliance indicated on the subsequent page (Table 6) of the CISCO manual only goes up to 30 dBi. This filing is proposing to use antennas up to 34 dBi, please revise accordingly. ANS: Please disregard the Cisco draft manual previously submitted. The Cisco manual currently addresses the MMDS ODU head and will require additional revisions to include the UNII transceiver. The antenna gains shown in Table 6 are for MMDS at an output power of 33 dBm . The corresponding table for this UNII product is found on the revised page 7 of the WJ installation instructions The table reflects highest EIRP values allowed by Part 15 and are applicable to 12 MHz channels. Power and EIRP for 6 MHz channels would be 3 dB lower. This table will be reproduced on revised page 7 of the WJ instruction manual. The revised page 7 is submitted as a separate attachment to this correspondence. (c) Distances for both uncontrolled and controlled exposures are indicated in Table 6. There is no explanation to the installer or user on which exposure distances are applicable for what conditions. Note: unless professional installers have been specifically trained on RF exposure requirements and know how to satisfy controlled exposure limits, uncontrolled limits should be used. ANS: Please disregard the Cisco draft manual previously submitted. The Cisco manual currently addresses the MMDS ODU head and will require additional revisions to include the UNII transceiver. The revised page 7 of the WJ draft installation manual will contain Table 2 showing only uncontrolled exposure distances. Controlled exposure limits will not be addressed, only uncontrolled exposure limits will be used. (d) It is not clear if the minimum distances indicated in Table 6 for controlled and uncontrolled exposure requirements are antenna installation requirements or distances for persons to maintain. The WARNING statement indicates hazard may exist, determine antenna gain and locate minimum acceptable distance; but there is no RF exposure compliance requirements. It should indicated to users and page 3of 4 pages tel: 650-726-1263 fax: 650-726-1252 internet: [email protected] installers about their responsibility to install antennas according to requirements in order to comply with FCC RF exposure requirements. ANS: Revisions have been made to the WJ manual to address these items. Please refer to the revised page 7 for the WJ draft user manual. 5.

Page 7 of the WJ Beta Draft 2 instruction manual will be modified as follows: BETA DRAFT2 - WJ CONFIDENTIAL Antenna Installation Instructions: FCC RF Exposure Limits The WJ SX11xx series of UNII transceivers, used in conjunction with 18 - 34 dBi gain antennas, are to be employed in point -to- point applications only. Antennas used for these transmitters shall be professionally installed on permanent structures for outdoor operations. The installer is responsible for ensuring that the systems using high gain directional antennas are used exclusively for fixed, point-to-point operations. The installer shall mount all transmit antennas so as to comply with the limits for human exposure to radio frequency (RF) fields per paragraph 1.1307 of the Federal Communications Commission (FCC) Regulations . The FCC requirements incorporate limits for Maximum Permissible Exposure (MPE) in terms of electric field strength, magnetic field strength, and power density. The WJ UNII transmitters are intended to be installed in restricted access areas, where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security. Regardless, antenna installations shall be engineered so that MPE is limited to 1 mW/cm 2 , the more stringent limit for "uncontrolled environments". Table 2 below specifies the minimum distance that must be maintained between the antenna and any areas where persons may have access, including rooftop walkways, sidewalks, as well as through windows and other RF-transparent areas behind which persons may be located.
