To demonstrate that professional installation is required, the following three points must be addressed: (a) the application (or intended use) of the EUT; (b) the installation requirements of the EUT, and (c) the method by which the EUT will be marketed. "The professional installation is required due to the following: 1. The MA850a cannot be sold to the general public, but only to the system's MobileAccess Inc. The customers of this company are exclusively qualified by MobileAccess. When the MobileAccess Inc sells the system to cellular provider or building owner companies, only professional installer, qualified ("licensed") by MobileAccess for this purpose will install the MA850a. 2. The installation must be controlled and follow the requirement of "Installation Manual". Each potential installer receives special training, which is a condition for receiving the license from the MobileAccess Inc to become a "licensed" installer. The installation itself is a complex procedure, as described in the "Installation Manual". It includes not only the mechanical installation, but additional procedure of interconnection to the main computer via modem, software initialization, registration of the specific MA850a in the MobileAccess Inc control center, initiation procedures. Specially trained professional only may perform all these tasks. 3. The intended application of the system is exclusively for the commercial/industry use.

Page 1 of 5 Summary, Conclusions, and Final Proposals Regarding Mobile Access Networks Model 850A From Meeting March 8, 2006 Attendees: FCC – Rashmi Doshi, Joe Dichoso Mobile Access – Steve Blum ATCB – Tim Johnson Intro: Several Items were not apparent regarding approval of this device and were discussed during the meeting. 1. First is that the device itself will only receive licensed services from previously approved devices/systems. 2. All 802.11 b/g and 802.11a inputs are also from previously approved devices. 3. Only the 802.11b chain is amplified. 4. The licensed services and 802.11a services are only PASSIVELY coupled via a triplexer with the amplified 802.11b devices. Furthermore, the triplexer provides 40 dB of isolation between each service 5. The system is only professionally installed. 6. The system will always contain the 4 b/g/a access points per documentation with all b/g ports connected. Much of this was only solidified in the final part of the meeting with Joe Dichoso (Rashmi Doshi was only present for the first ½ of the meeting). Items discussed/confirmations: Confirmation A: Whether composite powers are necessary to consider for the 802.11b and various 802.11a bands? The FCC stated that as long as information is present in the application to show that the various 802.11b and 802.11a signals are not coordinated, that composite power does not apply. FCC Comments: The device is a composite device consisting of multiple transmitters with absolutely no coordination between the transmitters either by design or installation(e.g. channel selection). *At the meeting, the installation did not involve mix and matching access points and only one FCC identifier was acceptable because 4 identical access points were to always be used. However, the submitted installation instruction indicates that two access points(two fcc identifiers) are chosen and there is no limitation on the number of each that can be used. Multiple FCC identifiers will be required for each configuration. The installation guide must be consistent with what is filed for. Confirmation B: The FCC will allow labeling of the 850A instead of the access point. The new ID effectively replaces any FCC ID’s on the access points. Ideally the FCC ID’s on the access points should be covered/removed/or marked through. Page 2 of 5 FCC Comments: Section 15.19(a)4 requires the ID to go on the main unit. For transmitter/amp approvals, we have been requiring the FCC Identifier to go on the transmitter not the amp. The FCC identifier of the access points should be covered up(not scratched off) with the new label. It is ok to place another label on the amplifier as well. Page 3 of 5 Confirmation C: Populating 802.11a inputs. Given the same access point contains both 802.11 g/b and a functionality, and the fact that the 802.11 a inputs are strictly passive connections through a triplexer and there is no depopulation of access points, the FCC stated that 802.11a connections are not fully necessary to be connected since this is only lack of a particular jumper cable from the access point to the 850A. FCC Comments: Confirmed. Confirmation D: During conversations, the FCC felt it would be acceptable that MobileAccess verify through testing (at the full power expected) that additional licensed services are not affected and do not affect the 802.11b/g and 802.11 a results. Should these results be found to be worse than previous results, then a Class II PC application will be utilized as appropriate. FCC Comments: You should test with a representative sample of licensed services signals. Confirmation E: Testing Requirements Expected by FCC. Licensed Services in Radiated tests are injected using an equivalent CW signal at what is considered maximum output power. 1) 802.11 b/g only tests. Complete compliance to all 15.247 rules should be shown for all applicable tests for just the 802.11 b/g operating at maximum configuration (4 x 802.11 b/g). This includes appropriate antenna conducted output tests and radiated tests as necessary. 2) 802.11a. It is assumed that all 802.11 b/g ports will always be connected per previous comments cited above. Therefore complete compliance to all 15.407 rules may be shown for all applicable tests for 15.407 operating at maximum configuration (4 x 802.11 a + 4 x 802.11b/g inputs attached). This includes appropriate antenna conducted output tests and radiated tests as necessary for compliance to 15.407. However depending on radiated results shown in 4) below, compliance for radiated portion may be able to be shown in a single combined test with licensed services therefore making separate 802.11a testing unnecessary. 3) Comparison of 802.11b/g signals (power and bandwidth) with and without licensed services as original required by Rich Fabina in the original 850 application. Note that Rich Fabina determined for the original application that the licensed services need not be tested by themselves due to the passive coupling and nature of being previously approved without an antenna: Page 4 of 5 It is assumed that this comparison is only necessary for the 802.11b/g due to the amplifier and switching matrix present in the 850A. 802.11a signals are only passively coupled and not deemed necessary. 4) Complete system, 802.11 b/g + 802.11a + licensed tests. Radiated data showing spurious emissions compliance to licensed limit (i.e. 43+10 log = -13 dBm) or possibly meeting spurious 15.407 limits. If compliance of all spurious can be shown to meet 15.407 limits in this configuration, it is proposed that separate testing of spurious radiated for 2) above is deemed not necessary. 5) Antenna Conducted Tests – When multiple transmitters share the same antenna, the FCC requires additional antenna conducted data. The following tests are anticipated to be required: a) Simultaneous TX of 802.11b/g + a. Antenna conducted tests to show compliance to - 17/-27 dBm/MHz EIRP requirements (without licensed services operating). Limits are ap…

HERM O N LA BO RA TO RIES July 5, 2006 American TCB 6731 Whittier Ave Suite C110 McLean, VA 22101 Attn: Mr. T. Johnson, Examining Engineer RE: your e-mail dated June 29, 2006; Mobile Access Networks Ltd. FCC ID:OJFMA850A, ATCB002924 Dear Mr. Johnson, Please find below the answers to your questions. 1) The revised file with a drawing “Label_850_AP_CISCO_rev1” was uploaded to ATCB on July 5, 2006. 2) The photographs underneath the shields of 5 GHz and 2.4 GHz cards were not provided because the cards, manufactured by Cisco Systems, were certified by FCC and have FCC ID:LDK102063 (5 GHz) and FCC ID:LDK102049. 3) The section 8.3 of the test report MOBFCC_16608_rev1 contains reference fundamental measurements with RBW=100 kHz and VBW=300 kHz for 20 dBc limit calculation. The calculated limit is approximately -13 dBm. The section 9.2, Table 9.2.2 and plot 9.2.8 contain the test result at 2.4 GHz with RBW=1 MHz and VBW=3 MHz. This case is worse than with RBW=100 kHz and VBW=300 kHz (as required by FCC section 15.247) and the result is below the -13 dBm limit. 4) The corrected User_manual_16608_rev.3 was uploaded to ATCB on July 5, 2006. 5) A page from Cisco website used as reference for FCC ID:LDK-102042 was uploaded to ATCB on July 5, 2006 via Additional Information folder. 6) We confirm that the maximum settings have been used for all tests. For gain setting please refer to User manual section 4.3 page 38. Sincerely, Marina Cherniavsky, certification engineer Hermon Laboratories

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 19, 2006 RE: Mobile Access Networks FCC ID: OJFMA850A After a review of the submitted information, I have a few comments on the above referenced Application. 1) Per FCC request upon review of the test plan, please confirm that the approval is for four 802.11a/b/g access points with all TX boards installed (802.11b/g and 802.11a boards in the listed access point) in each and also confirm that 4 access points will always be used/installed. 2) Per FCC discussions, it is acceptable to label the 850A, however this considered a secondary label on the amplifier portion of the device. Labels must also be placed on the access points themselves and cover any existing FCC ID’s on them. Please provide additional label exibits as necessary. 3) Since the approval is a system, please provide appropriate internal and external photos of the access points being approved with the system as well. 4) Section 6.7 of the report should include both 2.4 and 5 GHz. 5) Please update the 731 for to show 2.4 GHz information as well (i.e. DTS device, 2412 – 2462, etc.). 6) FYI...Proper testing for the 26 dB test for the UNII portion of the device should be done 26 dB from the peak emission measured on the same plot, not the power used as a reference level. Note that this result affects the limit applied for power. However since the more stringent level is used/applied, retesting is not necessary. However for any future tests or additional testing of this device should be performed properly. 7) Section 7.2 does not appear to use the more restrictive bandwidths necessary for the calculation (smallest bandwidth). Note that this result affects the limit applied for power. Please correct as necessary. 8) Table 7.2.2 appears to reduced the limit another 1dB to the limit, despite the previous page already appearing to take this into consideration. Please review. 9) Table 7.5.5 appears to use 10 Hz for the average emissions although the plots appear to use otherwise. Note that 10 Hz is only allowed for a CW signal. If the signal was pulsed in nature as shown in the power measurements, then the VBW must be > 1/Ton time for the appropriate data rate being used. Previous test report appear to handle this properly. Please review. 10) Readings in plots from 30 – 1000 MHz in section 7.5 and 8.4 show many readings over the limit < 100 MHz, but no tabular data. Please explain. 11) In section 8.3 and 8.4, kindly label all appropriate plots where the 802.11a emissions appear as well. It appears only one plot is labeled for this. 12) FYI..Table 8.1.2 mentions DSS for all modulations listed. I believe some of these were OFDM. z Page 2 June 20, 2006 13) Please verify the data in table 8.6.2. One data point appears odd. 14) Although a new report was provided, it does not appear the report covers all the expected tests. For instance, the FCC requires radiated and conducted for 802.11 b only (802.11a and licensed are off) per our test summary and comments previously provided. It does not appear that this has been provided,given the new report block diagram suggests radiated testing included all signals. It does appear that the new test report only provides test results for a composite set of inputs. (if previous results apply from the 850 for 802.11b/g only, please provide. However please note that the previous antenna is lower gain and therefore previous radiated results are not considered applicable). The following appears to summarize our understanding of what has been provided so far: Configuration Radiated RF Conducted 802.11 b/g only TXing Not Provided Not Provided 802.11 b/g and a only TXing Not Provided or possibly new report? Not Provided or possibly new report 802.11 b/g, a, and licensed TXing Provided originally Provided originally – 2.4 GHz data Additional Antenna Conducted Tests Provided in new report Provided in new report Note: It may be possible to perform a subset of RF conducted testing if the worse case results from the combined test can be shown to be the same (i.e. worse case power is measured for the 802.11b/g test and is shown to be the same as the 802.11 b/g, a, and licensed test). However if differences are noted, full testing should be shown. Note 2.4 GHz conducted data did not appear in the original report. Radiated results for 802.11 b/g, a and licensed appear to cover the 2.4 GHz for this combination with the exception of the bandedge for 2.4835 GHz at a high channel may not be clear. 15) The manual was corrected for several items per discussions with Steve Blum, ATCB, and the FCC and there was several items discussed with FCC and Steve Blum regarding this. Please provide a copy of the latest manual. Please note that the manual will require careful review for consistency with the application (i.e.: professional installation, access points approved, antennas, and any other pertinent information, etc.). 16) Previously not all data sheets were provided for all antennas listed in the manual for the approval being performed. However the most current revised manual also has not been reviewed and it is uncertain how many/what antennas are being covered. Does the application include appropriate data sheets for all antennas being approved in this application. 17) While the device may not stay connected via RS-232 (from previous responses), it does appear the device may stay attached via Ethernet (implied from the manual). If this port is intended to only be connected to an access point, then it would not qualify as a PC peripheral. However if this port is intended to connect directly to a computer, it would be considered a PC peripheral under 15.3. Please review/comment as necessary on if this connection is expected to remain after configuration. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Fai…
