Overview Figure 1.1 RSP-APA-002 Repeater R-tron RSP-APA-002 Repeater can be used in CDMA service hole spots like in-buildings, underground and tunnels to cover its service area. This repeater system designed for dual and simultaneous service, namely, it receives signals from the base station through donor antenna, amplifies the signals and re-transmits it to one or other mobile terminals. Also, it amplifies the signals which comes from mobile terminals through distributor antenna and re-amplifies it to base station. Using local OMT(Operation and Maintenance Terminal) which is connected between repeater control board and personal or laptop computer, it is possible to check or to control repeater status. With wireless modem which is in the repeater, it also enables to monitor Sprint WNMC(Wireless Network Management Center) in a remote place. RSP-APA-002 User’s Manual R-tron., Inc. 4/34 page 2.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 April 14, 2006 RE: R-Tron, Inc. FCC ID: STE-SP-APA-002 I have a few comments on this Application. Depending on your responses, kindly understand there may be additional comments. 1.) Please revise your Form 731 to indicate the frequency range being the center frequency of the lowest channel to the center frequency of the highest channel. This is FCC policy for any broadband transmissions which operate in any non-channelized Rule sections. Part 24 does not specify the channelization, therefore this interpretation applies. 2.) The FCC ID on Form 731 does not match the Label. Is there a typo? 3.) FCC interpretations specify that all views of all circuit boards with all RF shielding removed should be submitted. It appears that many views include this shielding. Please review. 4.) The Confidentiality Request includes Exhibits that are not typically included in any Confidentiality request. In general, FCC will keep as Confidential only Schematics, Block Diagram, Operational Description, Parts and Tune Up procedures. Kindly provide a detailed rationale for including any additional Exhibits. We may need to seek guidance from FCC as required. 5.) The Manual includes a Block Diagram exhibit. Since you have requested Confidentiality treatment for all Block Diagrams, there appears to be a conflict. Please review. 6.) The Manual doers not contain any RF Exposure information for installers. Typically installers must be given instructions as to how to protect the general public from excessive RF Exposure. There is information contained within the separate RF Exposure exhibit which should appear in the Manual. 7.) If desired, an Agent Authorization request from R-Tron to Estech should be included with this filing. 8.) In general, all repeaters must provide a plot of any input signals and their levels. This does not appear to have been done. Please supply. 9.) You have only requested CDMA (F9W) as a legitimate input/output signal for this device. However, for North America there are many different schemes which can operate within the Part 24 bands. Since from the Block Diagram it appears that this device does not demodulate the received signal, kindly provide an explanation how only CDMA emissions will be selected and repeated. 10.) FYI: It would be useful to provide a gain table or chart showing how this device handles RF Pout changes relative to input signal level. As a suggestion, a chart showing input vs. output levels from an input level of -70 to -30dBm (these are simply suggested values) would be useful for understanding this device. William H. Graff President and Director of Engineering 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.

The device supports only Block A band of US PCS. (15MHz band) So, we apply just PCS A band for it. 2. I uploaded the revised label form and 731 form of it on ATCB web. 3. I know for that. But, we can't open the duplexer. 4. I uploaded the revised confidentiality request letter on ATCB web. 5. Because we correct the confidentiality letter, the manual is ok. 6. It is included page 8 bottom of the manual. 7. I uploaded the Authorization letter on ATCB web. 8. It is included page 9 of RF test report. 9. The repeater is just an amplifier. So, it is not modulate and demodulate. It just amplifies the input CDMA signal. In this case, should we select which emission code? Please recommend us for it. My client wants to get the grant of it within tomorrow. If you need anything, let me know. Thanks. SUNG RYUL KIM Estech Co., Ltd.

The receive antenna height and turn table rotation was adjusted for the highest reading on the receive spectrum analyzer. For CDMA signals, a peak detector is used, with RBW = VBW = 3MHz. For AMPS, GSM, and NADC TDMA signals, a peak detector is used, with RBW = VBW = 1MHz, A Horn antenna was substituted in place of the EUT. This Horn antenna was driven by a signal generator and the level of the signal generator was adjusted to obtain the same receive spectrum analyzer reading. This spurious level is recorded. For reading 1GHz, the above procedure is repeated using horn antennas and the difference between the gain of the horn and an isotropic or dipole antenna are taken into consideration.
