QUH-40345Intelligent Booster Amplifier

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 30, 2003 RE: FCC ID: QUH40345-04_ATCB000370 Attention: Mark Betts I have a few comments on this Application. 1. The power in the documentation needs to be consistent. Please note that the manual and specs state the uplink power to be 31dBm yet the measured power is 28.82dBm max. This is a difference of greater than 2dB. Please make the technical specs and the measured power consistent (within +/- 1 dB). x 2. Please note that the document labeled as the manual appears to be more of the theory of operation and parts list. If this is to be confidential, please include this in the request for confidentiality – also, to justify the manual as confidential please include a short justification as to how and where this device is to have limited access only to qualified personnel. x 3. Please provide the tune up procedure for the device. Alternately, please explain why no tune up is necessary. x 4. Please provide the rf exposure information for this application. x 5. FYI - no action needed unless the block diagram is to be confidential. Please note that the report contains the block diagram of the system. If the block diagram is to be listed as confidential it must be listed on the confidentiality request and removed from the report. x 6. Please verify that the signal amplified is indeed the signal received at the input of the system. The schematics for the preamplifier and the PA are only shown. The block diagram appears to show only filtering but it is not completely clear if the received signal goes through any alteration. If the input signal is demodulated and or altered (other than filtering) then the device may not be an amplifier. Also, please verify that the receiver in the system does not modify the input in anyway but is only used for authenticity of the incoming call. x 7. Since the amplifier filters the input, please provide the schematics for this filter. x 8. Please note that the input vs output data for the uplink show an anomaly. Please refer to pages 30 to 33. The input level from -36dBm to -26dBm show the same output. It is expected that the amplifier should react the same way as with the input vs output of the downlink. The data would suggest that the gain of the amplifier may be saturated at the two levels mentioned. Please explain. x 9. Please note that your limits are incorrect on pages 37 to 42. The limit is not 13 dB down from the fundamental the limit is 43+10logP of the fundamental. This relates to -13dBm as the limit. Please correct your report to show the proper limits as defined in 22.917. Please pay very close attention to 2674MHz, 2547MHz, 3396MHz, 3368MHz, 3340MHz, 2539MHz, 1670MHz, 2505MHz, 769MHz and 3296MHz as these appear to be failing. 10. Please note that radiated spurious emissions are not QP as listed in your report, but ERP values using antenna substitution method. Please provide the ERP values for the radiated spurious emissions. Please note that the limit is again 43+10Log P or -13dBm not 13dB down from the fundamental ERP. Please correct your report to show compliance using proper 22.917 and TIA603 methods. Please be aware that there are a number of frequencies that may not be compliant – thus requiring further testing. 11. Please note that the first set of plots in the report are done at a correct RBW as we discussed, however, the block edge plots starting on page 53 of the report were done at the lower than the allowed bandwidths. Your resolution and video bandwidths on the block/band edge plots starting on page 53 are 3kHz. Please note that the lowest allowable RBW required for block and band edge measurement is 1% of the 26dB band width (for a CDMA about 12.5kHz). While the device may be compliant, you must still use the required RBWs. Please correct your report to use the proper RBW and VBW in accordance with 22.917 12. z Page 2 June 30, 2003 Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application.

I have inserted the plots that were needed. I don't know, I must have just lost my mind for a minute. For the rest, VCOMM is working on it and I should have all on the server today. Thanks, Mark -----Original Message----- From: dward [mailto:[email protected]] Sent: Thursday, July 17, 2003 4:29 PM To: [email protected] Subject: RE: VCOMM! Hi Mark Here are the items that have not been addressed or addressed only in part. 1 In the band edge plots I do not see where you provided the full complement of plots. You have the right number of plots but they do not address both sides of the block edges. For example, for the 824 to 835 and 835 to 845 you have block A's 835 band edge but I do not find block B's 835 band edge. The same for Block A 845 to 846.5 and block B 846.5 to 849 I don't find block Bs 846.5 plot. Am I missing something? 2 You will have to extract the tune up section from the specs and provide it as a separate exhibit. 3 Also, you have not addressed if the technical specs is also the manual. See item 2 of the comments. Please clearly state that this is the documentation that is provided to the end user or installer. If not, please provide that document that the end user gets. 4 The rf exposure mentions that the separation of the antenna to any user is at least 2 meter. Yet no where in the documentation can I find this distance mentioned. I should be able to issue the grant Friday if all goes well. Thanks Dennis

General Description: The Intelligent Booster Amplifier (IBA) is intended to improve cellular telephone coverage in weak signal areas. The IBA communicates with standard cell site transmitter/receiver network via an external antenna that is positioned within the coverage area of the standard system (primary antenna). Via radiating cable or other local antenna (secondary antenna), the IBA then amplifies and repeats these communications to mobile cellular handsets within the thusly-expanded coverage area. 2. Classification and Environment: FCC Part 22, Public Mobile Services and TIA/EIA 603 Land Mobile FM or PM Communications Equipment Measurement and Performance standards are applied to the Intelligent Booster Amplifier. 3.
