These trade secrets can be found in the repeater schematic diagrams, files Schematic_CHANNLER_15557(7 pages) and Schematic_LNA_15557 (2 pages) of this Application. Many thanks in advance. Sincerely yours, Moshe Minkin Quality Assurance director Decolink Wireless Ltd

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 28, 2003 RE: Dekolink Wireless Ltd. FCC ID: OIWDR80050W90B After a review of the submitted information, I have a few comments on the above referenced Application. 1) The FRN Number provided (0009032668) appears to be invalid from checking on the FCC website. Please provide a correct FRN number for Dekolink Wireless Ltd. 2) Clear Top and Bottom Photographs are required for all components in the RF path (Filters, Amplifiers, Channler, Diplexers, etc.). Additionally, most photographs provided are not clear enough (when possible these should be focused, not too dark, with no glare spots) or show adequate detail. Please provide clearer and/or higher resolution photographs. 3) Due to the fonts style uses on the label, the letter "S" and Number "5" and the letter "B" and Number "8" can not be adequately distinguished. Please provide an updated label that utilizes a different font. 4) Parts lists should be provide for all components given in the RF path. The information provided shows that the high power amplifiers are OEM equipment. Are the LNAs, Channler, ALC circuits, diplexers, Digital Filters, etc. designed and/or built by Dekolink? If so, please provide internal parts lists for all components in the RF path manufactured by Dekolink. Otherwise, please provide a parts list that shows the vendor of each of these components used. 5) It appears that the schematics provided are only for certain components in the RF path. Schematics should be provided for all aspects of the RF path manufactured by Dekolink, unless they are listed as OEM equipment in the parts list. Please provide any missing schematics. 6) For purposes of the FCC grant, please confirm that this devices retransmits the same frequencies received. If not, please provide further explanation of the EUT. 7) Please provide a Tune up procedure over power range. 8) Note: FYI, because this is a licensed device, RF exposure issues are addressed at the time of licensing for the end user of this device. Therefore the RF exposure exhibit has not been evaluated. It is suggested that the RF exposure section also be removed from the test report. 9) This device contains ALC/AGC circuitry. Please explain the derivation of the input drive level provided into the EUT in order to obtain the maximum power output. 10) Since the device contains AGC circuitry, please provide data/tables showing the measured output power vs. input level from the lowest expected input to the maximum rated input power allowed (approx -51 dBm to +10 dBm, etc.) 11) The maximum output rating for the downlink in the test report is 9.55 Watts. The operational description states a 10 Watt rating. Note that the FCC expects the unit to be adjusted for worse case conditions expected while following the tune up procedure performed by the factory. The worse case condition will be shown on the grant and it is expected all manufactured units will be equal to or less than this value. Please verify the worse case output power and if necessary have the manufacture adjust for worse case conditions following their tune up procedures and remeasure. 12) Please comment on if this device is designed for single carrier or multi-carrier use. Has the output power been checked for multi-carrier conditions? 13) Please comment on if the input signals supplied to the unit are considered a typical expected input signal (level and modulation). Additionally, please provide a list of expected modulations for use with this device (731 form listed D7W). Note that certain tests must be performed for all expected modulation types. 14) Please provide justification for the use of D7W emissions. -- Continued on Next Page -- z Page 2September 2, 2003 15) Radiated spurious emissions are not necessary to be performed for 3 carriers but instead with a narrow band CW signal. Note that a single channel creates a higher power level which usually creates higher level spurious emissions. Please provide additional radiated spurious emissions for a single carrier configuration. For future applications it is necessary to only perform this test using the single carrier method. 16) It appears as if plot 58 and 59 are identical and that a plot may have been left out. Please verify. 17) Conducted measurements were made using 2 carrier signals. Since the ALC circuit is based on composite power, and a single carrier will contain higher power with possible higher sidebands, please provide additional plots using a single carrier. 18) Section 4.5 (radiated emissions) should be performed using the substitution method. It does not appear that this occurred. Please explain. 19) FYI...An easy way to deal with limits for antenna conducted is that 43 + 10 log (P) equals a limit of -13 dBm. 20) FYI...The FCC just released basic checklist to TCB's regarding this type of device. Although not considered complete, it gives a basic idea of some of the FCC's expectations. I have enclosed this in an attachment for future reference. Timothy R.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 August 28, 2003 RE: Dekolink Wireless Ltd. FCC ID: OIWDR80050W90B After a review of the submitted information, I have a few comments on the above referenced Application. 1) The internal photographs appear appropriate, but are too low of a resolution to adequately see the detail. It appears that the conversion settings for PDF may need to adjust the resolution settings. Please increase the resolution of the exhibit provided. 2) When multiple inputs were applied during testing, please explain if the maximum/minimum input values used (uplink = -33 to -60 dBm, downlink = -23 to -50 dBm) were based on a per channel input power or composite input power. If the input values used are based on a per channel value, all spurious/emission mask tests have been provided. If the input value is based on composite power of all channels, additional emission mask bandedge plots using lowest/highest channels should also be provided for a single carrier. This is due to the fact that the single channel will now contain higher power at a specific frequency than in a multi-channel configuration. Note that our previous correspondence regarding testing methods was before we realized the device actually contained AGC circuitry. Please note that multi-carrier and AGC types of amplifiers sometimes require some additional information. 3) Please provide a curve or equivalent data that shows the measured output power vs. input level from the lowest expected input to the maximum rated input power allowed (approx -51 dBm to +10 dBm, etc.). This may be provided by the manufacturer if this is something they already have performed. This information is used to check the characteristics of the AGC circuitry and ensure that use of the minimum/maximum levels is considered sufficient for all levels expected. 4) To ensure that the AGC works properly, please provide an additional output power measurement using multi-carriers (2 measurements, both carriers with minimum levels, the other with maximum levels should be sufficient). Currently we know the output value for a single channel configuration. Assuming the maximum output power is composite power, we want to ensure that the multi-carrier value is equal to or less than the single channel value and that the AGC works appropriately. This also helps to verify that the power is composite power and not strictly a per-channel power requirement. 5) FYI...Due to the results of radiated being < 20 dB below the limit, we will accept the current radiated data. However, to help make future applications simplier, this test is only necessary to only performed using a single carrier method. Timothy R.

The RF signal entering the repeater, is filtered by a duplexer, amplified, down converted & sampled to digital signals. The digital signal is filtered using fast parallel logic. Using digital processing techniques, the system generates up to 8 separate, programmable and independent filters. After filtration is accomplished, the digital signals are up-converted to an RF signal, amplified by a High Power Amplifier & combined by a duplexer to the output port. REPEATER CONNECTION: The RF connection is made via two type “N” female connectors. The RF connector labeled “Base” is connected to the antenna pointing to the base station, usually a rooftop antenna; this is a directional antenna such as Yagi or Dish antenna of 14 to 18 dBi gain. This antenna is pointed to the base station to get maximum input power. The RF connection labeled “Mobile” must be connected to the antenna pointing into the area to be covered by the Repeater. The remote antenna is usually a directional antenna designated for the coverage requirements. For indoor applications covering a large building, the RF signals are split using power dividers and distributed to many antennas, usually omni antenna, each covering a floor or a small area. such as inside a building or outdoor shaded area.

Uplink and Downlink LNA Blocks with level control (ALC).LNA with ALC supplied constant signal level to Digital Filter units 2. Uplink and Downlink Conversion blocks. Conversion blocks receive RF signal ,through LNA block, filtering and down convert frequency (by down mixer and synthesizer) to IF. In IF section the signal is amplified and supplied to Digital Filter. After digital processing and filtering, digital signal up converted the IF frequency (by up mixer and synthesizer) to RF. The RF signal is filtering and supply to Preamplifier block. 3. Uplink and Downlink Preamplifier blocks with gain control (AGC). RF signal from Conversion block amplified and supplied constant level (by gain control) to Channler output. 4. Microcontroller block. Microcontroller receive alarms from all Channler blocks, process the data and through to external controller. Microcontroller receive from external Controller settings controls (Frequency, ALC , AGC, Power) and through to the all Channlers blocks.
