Page 1 of 3 Please make the following changes to the N2-X Ethernet Extender Manual: Change antenna gain numbers (dBi) in Table 3.1 to values shown below, and add text between table heading and table as shown: Table 3.1 - Maximum Transmit Power Level Setting vs. Antenna Type (for compliance with FCC EIRP limits) in the 5.3 GHz band Per the following table, in the 5.3 GHz band the highest power setting (approximately +12 dBm) can only be installed with the lowest gain antenna which is the 6” Flat Panel Plane Polarized (DFPD.5-52) with 17.5 dBi. Each radio is shipped from the factory with a standard 6’ coaxial cable for connection between the radio and the antenna. The cable has a nominal loss of approximately 2.6 dB. UNII radios are covered under CFR 47 FCC part 15, 15.407 Subpart E. 15.407.a.2 which states Ptransmit = 11 dBm + 10 log B where B is the -26 dB BW with a 6 dBi antenna. Above 6 dBi antenna gain there is a 1:1 reduction in Ptransmit to maintain the same MAXIMUM EIRP. This is accomplished by the changes in output power setting for the alternative antennas. The FCC EIRP limit for the 5.3 GHz band with our transmitter bandwidth is +28 dBm. With the transmit power set to +12 dBm, the EIRP with the 6” Flat Panel antenna, and standard 6’ coaxial cable will be: 12 dBm + 17.5 dBi –2.6 dB = 26.9 dBm.

This is a duplicate of the above statements. Table X.X - Maximum Transmit Power Level Setting vs. Antenna Type (for compliance with FCC EIRP limits) in the 5.3 GHz band Per the following table, in the 5.3 GHz band the highest power setting (approximately +12 dBm) can only be installed with the lowest gain antenna which is the 6” Flat Panel Plane Polarized (DFPD.5-52) with 17.5 dBi. Each radio is shipped from the factory with a standard 6’ coaxial cable for connection between the radio and the antenna. The cable has a nominal loss of approximately 2.6 dB.

Each radio is shipped from the factory with a standard 6’ coaxial cable for connection between the radio and the antenna. The cable has a nominal loss of approximately 2.6 dB. UNII radios are covered under CFR 47 FCC part 15, 15.407 Subpart E. 15.407.a.3 which states Ptransmit = 17 dBm + 10 log B where B is the -26 dB BW with a 6 dBi antenna. Above 6 dBi antenna gain there is a 1:1 reduction in Ptransmit to maintain the same MAXIMUM EIRP. This is accomplished by the changes in output power setting for the alternative antennas. The original FCC EIRP limit for the 5.7 GHz band with our transmitter bandwidth is +33 dBm. With the transmit power set to +12 dBm, the EIRP with the 6” Flat Panel antenna, and standard 6’ coaxial cable will be: 12 dBm + 17.5 dBi –2.6 dB = 26.9 dBm. The corresponding settings are included in the following table. Antenna TypeManufacturer P/NMaximum Transmit Power Setting (dBm) 2’ diameter dish with radome, Plane Polarized, 28.1 dBiGabriel SSP2-52ARI0 2’ diameter dish with radome, Dual Polarized, 28.1 dBiGabriel SSD2-52ARI0 6” Flat Panel, Plane Polarized, 17.5 dBiGabriel DFPD.5-52+12 12” Flat Panel, Plane Polarized, 23 dBiGabriel DFPD1-52+8 24” Flat Panel, Plane Polarized, 27.5 dBiGabriel DFPD2-52+4 The FCC will also allow higher EIRP for point to point links with higher gain antennas. Page 703 of the FCC document, CFR 47 FCC part 15, 15.407 Subpart E, FR 40836, July 31, 1998 has the provisions for these power limits. The path length isn’t increased, since the 5.3 GHz transmitter isn’t allowed the higher EIRP. We recommend the higher power settings only when absolutely necessary. This rule states " fixed pt-pt U-NII devices operating in this band may employ transmitting antennas with directional gain up to 23 dBi without the corresponding reduction in transmitter peak output power or peak power spectral density”. Also above 23 dBi antenna gain there is a 1:1 reduction in Pout to maintain the same MAX EIRP. We are in compliance even at the maximum antenna gain and transmitter power, since the corresponding output power is over +27 dBm in our BW and the resulting EIRP for a 6 dBi antenna is +33 dBm. This EIRP limit is further …

Corrections to N2-X Ethernet Extender Installation and Operation Manual (12-17-99 .pdf version) Page viii Change second paragraph to read: Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal Communications Commission's Office of Engineering & Technology, limits for the maximum permissible exposure (MPE) to microwave signals have been adopted by the FCC for General Population/Uncontrolled environments. This limit is 1.0 mW/cm 2 , with averaging time of thirty minutes. Change 8 th paragraph to read For example, a logarithmic power gain of 17.5 dB is equal to a numeric gain of 56.23. Change 9 th paragraph to read Assuming (1) maximum output power from the N2-X Ethernet Extender (+12 dBm[15.8 mW]), (2) no signal loss in the cable connecting the N2-X Ethernet Extender to the antenna, and (3) the use of a 17.5 dBi gain flat panel antenna, the 1.0 mW/cm 2 MPE power density limit would be reached at a distance of approximately 8.4 cm. The N2-X Ethernet Extender is classified as a fixed installation product, and per FCC policy guidelines regarding MPE, antenna installers must maintain a separation distance of 20 cm or the resulting calculation of distance from transmitter EIRP, whichever is the greater distance. Page B-2 Make the following changes to Table B.1: - Eliminate last column , heading: 2.5ft (0.8mm) antenna - Correct heading of second column to read: 2ft. (0.6m) Antenna - Correct dimension K, column 2 to read: 24" (610mm) Page 9 Change footnote to Table 2.3 - Recommended Antennas to read: *The 4-foot dish antennas are for use outside the USA only, and are not FCC compliant.

N2-X Ethernet Extender Bridge product, submitted for approval and certification on or about July 12 th , 1999. FCC ID: EV9N2X5-7S1-16B, Confirmation number: EA94795 My Client has made several changes to the production version so please except the contents of this package for review and disregard what was previously submitted. The N2-X 5.7 GHz Radio has been modified and improved for performance. This product has variable power settings for each of the eight- (8) channels. The unit was tested at each of the power levels for the LO, MID and HIGH channels configured with four (4) different antenna types for your review. The gain of the antennas is paired with the various power settings to meet the limits called out in CFR Title 47, Part 15 of the Rules and Regulations. The report reflects the new limits called out in 15.407. Please review the file titled “N2-X differences” for a description of the design changes in the latest production model. Also enclosed is an original Agent Authorization letter from Wireless, Inc. authorizing Electronic Compliance Laboratories, Inc. to act on their behalf. In addition, all of the exhibits thought necessary to support this application are included, along with a confidentiality package. Due to size of the package the format in which I am submitting is a little different. The report document 9080501A references various appendices, Each appendix is a separate PDF file saved as “APPENDIX A” for example. Let me know if you have any problems with the format and I’ll make the adjustments as you see fit. The Theory of Operations can be located in “APPENDIX J” with the other confidential information. The following documents are being sent to replace the exhibits of the application presently in Technical Review. These documents are being submitted for FINAL consideration for Certification: FCC ID: EV9N2X5-7S1-16B WIRELESS, INC.

My hopes are that you would review this package and let me know if this will still be a requirement. The unit was tested very thoroughly and they are pretty solid radios. I was looking at my schedule and thinking about yours, and this will be just another thing I’ll have to prepare for. The stack is getting higher, so as soon as you know something. I would appreciate a notification and at that point, if it’s not a problem, I would request to take your earliest available opening and I will make sure the unit or units will be hand carried there for testing. Just an effort to try and expedite the time involved and to eliminate any complications or hassles with the shipping or whatever... If there are any questions or problems please don’t hesitate to contact me at the number listed above, or by email, [email protected]. I look forward to hearing from you and I’ll talk to you then.
