November 28, 2005 American TCB 6731 Whittier Ave. Suite C110 McLean, VA 22101 USA Subject: Request for confidentiality for Wireless Modem Unit, FCC ID:PBJV284-PLUS-C Dear Gentlemen, In regards the exhibits submitted in support of the application for FCC ID:PBJV284 -PLUS-C, please classify the following as confidential under the provision of 47 CFR 0.459: 1) Schematic diagram, file “Schematics_16751” (1 page). 2) BOM, file “Parts_list_16751” (2 pages). 3) Circuit description, file “Circuit_description_16751” (2 pages) The above material contains trade secrets or technical data which Vyyo Inc. deems to be proprietary. Therefore this information would customarily be guarded from competitors and cannot be accessible to the general public. Sincerely, Dr. Mike Ritter V.P. Marketing

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 December 6, 2005 RE: Vyyo Inc. FCC ID: PBJV284-PLUS-C After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please explain how the 75 to 50 ohm conversions were taken into account in any testing done with a direct attachment to the antenna port (i.e. power, conducted spurious, bandedge etc.). The concern is that many measurements are marginal to limits, and typically the insertion of a minimum-loss pad (75 to 50 ohms) requires a correction of about 5.72 dB. Please provide detailed explanations as previously provided for earlier applications. 2) Please explain how power output was calibrated in terms of RMS equivalent voltage according to 27.50(c)(4). 3) Please define and justify the use of the emissions designators given on the 731. Note that the measured bandwidths appear different than on the 731. Additionally, please clarify which is intended for QPSK and which is intended for QAM. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

HERM O N LA BO RA TO RIES December 20, 2005 American TCB 6731 Whittier Ave Suite C110 McLean, VA 22101 Attn: Mr. Timothy Johnson, Examining Engineer RE: your e-mail dated December 16, 2005; Vyyo Ltd. FCC ID: PBJV284-PLUS-C, ATCB002991 Dear Mr. Johnson, Please find below the answers to your questions. 1) For test setup please refer to pages 8 and 15 of the test report – the setup contains “75 to 50 Ohm Minimum pad loss” with 5.72 dB attenuation. The correction factor was included in spectrum analyzer readings. 2) For the power measurement we used the RMS/video detector function in the Agilent E7405A spectrum analyzer. The test report with corrected page 9 (HL 2780 instead of HL 1653), file VYYRAD_FCC.16571_rev1 was uploaded on December 20, 2005. 3) We used the Emission Designator D1W for 16QAM and G1W for QPSK. The necessary bandwidth was taken from Table 7.6.2 of the test report for each type of modulation and the frequency band (as was done in your grant for previous Vyyo’s device FCC ID:PBJV284). Thank you for the help. Sincerely, Marina Cherniavsky, certification engineer Hermon Laboratories

Vyyo Inc FCC ID: PBJV284-PLUS-C Date: November 2005 Page 1 of 1 V284+C Tune Up Procedure over the power General: The modem output level is controlled by the WMTS in a periodic ranging procedure. The WMTS set the modem TX level such that it will receive a fix predetermined level. The procedure is based on the DOCSIS procedure. Step 1: Initial ranging: After acquisition of downstream signal, the modem starts to send upstream messages. The modem starts to transmit at the minimum TX level. If this signal was acquired by the WMTS, The WMTS will send an acknowledgment, including a message with a correction of the TX level (to be received at the nominal RX level). The modem is waiting to the acknowledgment. If the modem is not getting an acknowledgment, it increases the TX level by a 6 dB step. This procedure is going on till the modem is getting acknowledgment with the correct TX level, or till it arrives the maximum power. If the modem arrived the maximum power, without getting an acknowledgment, it starts the procedure from the beginning. Step 2: Periodic ranging After the initial ranging, the modem is getting a periodic ranging message from the WMTS. This message includes fine correction of TX level, if needed. The periodic ranging period is typically 3 seconds (can be define through the NMS). Maximum output power: The modem cannot transmit above a pre-defined output level.
