Please note that this list will be retransmitted as a second notice for the corresponding FCC application as it appears that the intent is to use the same report and other documentation for both applications. AN07I1974 Cisco 2461B-102062 Review Notes 1. Although the test report includes test parameters, it does not include reference to the specific standards and procedures employed. Please confirm that standards and procedures listed below were used in the testing of this product. Please either revise the test report or in this case it will be adequate to provide this confirmation via email. It is recommended that future test reports include specific references to the standards and procedures used. "Measurement of Digital Transmission Systems Operating under Section 15.247" FCC, March 23, 2005 ANSI C63.4-2003 <answer>Cisco confirms that the standards and procedures conform to the referenced document. 2. Page 23 of the test report includes reference to testing performed in the 5150-5725 MHz frequency range. This appears to be erroneous. Please revise the test report or provide additional explanation. <answer>revised test report is attached. 3. Page 8 of the test report refers to 5GHz average power that appears to be in error. Please revise. <answer>revised test report is attached. 4. Page 6 of the test report makes reference to Appendix E. The test report submitted has no Appendix E. Please revise the report. <answer>Cisco has removed the reference from the test report. 5. MIMO and Beamforming modes of operation are mentioned on page 5 of the test report. Please provide additional information in the test report, operational description or separate document relative to compliance with sections 15.247(c)(2)(i)-(iv) and the issues in the documents which can be accessed at the following URL's. http://www.fcc.gov/oet/ea/presentations/files/may05/Smart_Antenna_Systems_JD.pdf http://www.fcc.gov/oet/ea/presentations/files/oct04/Oct_04-Part_15_Updates-JD.pdf Specifically, provide information relative to the following: (a) number of beams formed <answer> When in beam forming mode, one beam is formed. (b) Confirm that the system uses Spatially Multiplexed MIMO technology only and not in combination with phased array or sectorized antennas. <answer> Most operating modes use only Spatially Multiplexed MIMO technology. Beam Forming is supported and covered in both the test report and theory of operation. (c) Confirm this is not a "Smart Antenna System" <answer> Beam Forming is supported and covered in both the test report and theory of operation. (d) Provide a block diagram and or description of how the test equipment was connected for output power, PPSD, and spurious measurements <answer> A photo of the conducted test setup is included in the test filing. It consists of the EUT connected to the spectrum analyzer through a combiner. http://mail.google.com/mail/?ik=2a69a1bf8a&view=cv&search=inbox&th=112009712a95480c&ww=1131&lvp=0&cvp=5&qt=&zx=zc3j243gj4hd (1 of 2)4/17/2007 3:01:46 PM http://mail.google.com/mail/?ik=2a69a1bf8a&view=cv&search=inbox&th=112009712a95480c&ww=1131&lvp=0&cvp=5&qt=&zx=zc3j243gj4hd (e) Whether simultaneous operation on multiple channels is possible and if so if this was investigated. <answer> Operation on only one channel at a time is possible. 6. The test setup photos show setups with co-located 2.4 and 5 GHz antennas. The EUT for radiated measurements has 6 rather than 3 antenna ports. No 5 GHz mode of operation information or 5 GHz measurement data (except spurious emissions) is included in the test report. Please provide additional information explaining the test modes and configuration. <answer>The 5 GHz radio shown in the test setup was submitted to the FCC in a separate filing(FCC ID: LDK102061). 7. The internal or external photos should show how and where connections are made to the antennas or antenna connectors. <answer> The antenna connections are clearly demonstrated in the Assembly Photos document included with the filing. 8. Please revise the user manual to include the following statements as required by IC RSS-GEN 7.1.4 and 7.1.5. "This device has been designed to operate with the antennas listed below, and having a maximum gain of [x] dB. Antennas not included in this list or having a gain greater than [x] dB are strictly prohibited for use with this device. The required antenna impedance is [y] ohms." "To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication." <answer>Revised on page 5-2 of the attached manual. 9. The test report does not include receiver spurious emissions data as required by RSS-Gen Clause 4.8. Please revise the test report to include receiver measurements. <answer>Added to the attached …

Cisco Systems, Inc. Page 3 of 7 Company Confidential 1. Introduction This document describes the set of specifications for a single patch antenna to be used in the 2.4 GHz band. The basic features of this antenna are as follows: • Directional antenna for indoor/outdoor operation • RP-TNC Connector with 3-ft of plenum rated, cold temperature capable cable. • Operates over the entire 2.4 GHz band. • Peak gain is around 6 dBi In general, this antenna will be housed in a white polycarbonate radome very similar to the Coho AIR-ANT2485P-R. It will be built with 3 feet of off-white plenum rated cable and terminated in an RP-TNC. The specifications for this antenna will be presented sequentially with Electrical Specifications first, followed by Mechanical/Environmental Specifications and General Specifications. 2. Physical Appearance The actual antenna inside the radome is expected to be built on a fairly large ground plane of about 90 mm x 100 mm (3.5 in x 4.3 in). This large ground plane size allows for the use of a simple radome that fits over the ground plane rather than use two pieces of plastic to form the enclosure. This will lend itself to a (roughly) square radome that may look something like that shown in the preliminary drawing in Figure 2.1.

Basically, this is a single patch antenna built with a high density polyethylene dielectric over a ground plane. The antenna will have 3 feet of white/off-white plenum rated coaxial cable capable of operating down to -30 C. 3.1. Antenna Electrical Specifications and Patterns The electrical specifications for this antenna are summarized in Table 3.1.1 below. H- and E-plane patterns covering the whole band are shown in Figures 3.1.1.and 3.1.2.

The basic features of this antenna are as follows: • Directional antenna for indoor/outdoor operation • RP-TNC Connector with 3-ft of plenum rated, cold temperature capable cable. • Operates over the entire 2.4 GHz band. • Peak gain is around 6.5 dBi In general, this antenna will be housed in a white polycarbonate radome very similar to the Coho AIR-ANT2485P-R except that there will be two cables. It will be built with 3 feet of off-white plenum rated cable and terminated in an RP-TNC. The specifications for this antenna will be presented sequentially with Electrical Specifications first, followed by Mechanical/Environmental Specifications and General Specifications. 2. Physical Appearance The actual antenna inside the radome is expected to be built on a fairly large ground plane of about 110 mm x 165 mm (3.94 in x 6.5 in). This large ground plane size allows for the placement of two patches over the same ground plane as well as the use of a simple radome that fits over the ground plane rather than use two pieces of plastic to form the enclosure. This will lend itself to a rectangular radome of about 110 mm x 165 mm x 25 mm. The actual antennas will be arranged on the ground plane as shown in Figure 2.1. The radome has not been designed at this time.
