Connections between cabinets are made through N‐Bulkhead connectors located on the top of each cabinet. All programming and adjusting is done through the software and this manual primarily deals with this topic. The computer running the software is connected via an RS232 serial cable to each channel card in the manner shown below. 50289‐BA‐8‐PA ‐5‐ MAIN SCREEN Below is the main working screen used to configure the channel card settings. The primary fields addressed are: • Communication Connection • Time Out Timer • Mode Setting • Key On Delay • Key Off Delay • Attenuation • Setting a Frequency 50289‐BA‐8‐PA ‐6‐ COMMUNICATION CONNECTION This software automatically checks the condition of its communication with the intended channel. Each message is acknowledged and displayed in the message box at the bottom of the screen. If the software does not receive a response from the channel, a warning message is displayed, “NO RESPONSE FROM UNIT”. 50289‐BA‐8‐PA ‐7‐ TIME OUT DURATION The time‐out duration is how long a channel can be held open (keyed on) for a retransmission. An inadvertent or intentional “key and hold” action without any voice communication will not disable the channel because of this feature. The time‐out duration can be up set from 1 second to 99 seconds 1 second intervals. The time‐out duration can be disabled by setting it to 00, when disabled, the channel will key continuously with the presence of a received signal. SETTING A TIME‐OUT TIME To set a time‐out time, click on the text box “Time Out Timer” and enter the desired time‐out time up to 99 seconds then click “Send Button” next to the box. To verify the setting, click on the “Read Button” and the display will be updated with the channel setting. 50289‐BA‐8‐PA ‐8‐ MODE SETTING The channel mode may be set to either INHIBIT, CONTINUOUS, CARRIER DETECT or optional TONE DETECT.

March 7, 2007 Mr. Tim Johnson American TCB 6731 Whittier Avenue, Suite C110 McLean, VA 22101 RE: Emailed comments APPLICATION: UT650289BA8800DL (ATCB4545) Dear Mr. Johnson: Below are the questions regarding this application posed to Washington Laboratories, Ltd. via email, and our responses. Please do not hesitate to contact us, should you have any questions. Sincerely, Steven D. Koster Brian J. Dettling EMC Operations Manager Documentation Specialist WLL Project #: 9520 7560 Lindbergh Drive Gaithersburg, Maryland 20879 (301) 417-0220 Fax (301) 417-9069 website: http://www.wll.com email: [email protected] 1) It appears that frequency translation is possible from looking at the block diagram, however operational description suggests that the TX frequency is same as incoming. However tables in the manual suggest only 8 channels can be output, but the software screens shown a large number of any 25 kHz channels as possible. The information is confusing and solid understanding on the operation and if it incorporates translation can not be determined. This should be clear as to understand how the device operates. Note that if it does translate frequencies, then frequency stability is required. a.) The device does not translate frequencies. The incoming signal is mixed with an LO to down- convert to 90 MHz and after filtering and amplification, the 90MHz is mixed with the same LO so the input and output frequencies remain the same. b.) The output RF will, therefore, not change with temperature or voltage variation. c.) The software is Airorlite’s general software. The frequencies for this device are listed in the table on page 2 of the manual. 2) The test report and other documentation states this is a bi-directional booster. If it were bi-directional we would expect to see the uplink data. Uplink info is in the other application, so apparently both applications make up the bi-directional aspect. If this is the case then the terminology is not correct as each device being certified would only be a directional booster/repeater and not bi-directional booster. The operational description, manual and test report and other documentation must make this fact clear. Currently the operational description will red-flag this application because it discusses a bi-directional amplifier. At a minimum, a note should be added to the PDF file that only the downlink amplifier portion of this system is being Certified. Otherwise first impressions are that what is Certified and what the operational description is are two different items. A similar problem can be assumed about the block diagram. The block diagram is actually system level but was not clearly understood what part of it covers the application until deep into the application itself. It would be best for the block diagram to have a note or markings showing what part of the system the application is covering. The report in each case has been edited to show that there are two applications: One is for a downlink booster and the other is for an uplink booster. The system as a whole is a Bi-directional booster; this application is for the downlink channels. 3) I did not find any information regarding the emissions the device/system is designed to use in the manual or operational description. The test report simply cited "depends on system". Amplifier guidance "attached" clearly states investigation of the different modulations is required for certain tests (i.e. power, conducted spurious, intermodulation, and input/output bandwidths - but see guidance for complete detail). Therefore justification as to the F1E designator should be provided and depending on intended use of the device - additional emissions may need to be investigated for certain tests. As is, this device could only be used for F1E signals. The Form 731 (50289DL Application Form - 731 revised 3.07) has been revised accordingly: The emission designator has been changed to “F8E”. The system is employed to augment analogue, frequency modulated voice communications. The device is capable of 8 channels of operation. Hence, from FCC 2.201: F: Frequency Modulation 8: One or more channels containing analogue information E: Telephony 4) Frequency tolerance should cite "amp" unless frequency translation occurs (as mentioned above). The Form 731 has been revised accordingly. 5) Given the uplink/downlink are separate, to clarify this and how the device is used, the grant notes should contain: “Part of booster system used with FCC ID: xxxyyy.” Acknowledged. 6) Booster rules cites: – Include exhibit or correspondence showing applicant was informed that boosters must meet all criteria stated in Sections 90.219 and 22.383 for related booster/inbuilding operations. NOTE: THIS APPEARS TO BE A CLASS B DEVICE UNDER 90.219, AND IF SO, SHOULD ADEQUATELY JUSTIFY AS SUCH. The applicant is informed. See letter (Airorlite Pt90.219 Letter). 7) While radiated spurious may use a CW signal, conducted spurious requires to test all modulation types [TDMA, CDMA, and FM (covers GSM andF1D)] at low, mid. and high frequency. Given 3) above, it is uncertain if this is covered appropriately. This device is designed to be used with FM input/output signals. Other modulation types are not required to be characterized. 8) There does not appear to be information to support that input drive level is at maximum input rating and maximum gain settings for all tests. Given this is basically and amplifier, this should be documented/justified....Additionally an explanation of what keeps the device from going into saturation should be provided...Generally amplifiers, booster, and repeaters must justify the levels used for test and document them as appropriate. See attached guidance as well... The drive level was supplied by the customer. The optimal drive level was derived from empirical measurements provided by the customer on actual installations. A -50dBm level was found to represent the highest incoming stimulus signal. 9) Power on grant shoul…

Response to ATCB Comments FCC ID: UT650289BA8800DL 1 Washington Laboratories, Ltd. 7560 LINDBERGH DRIVE GAITHERSBURG, MD 20879 (301) 417 – 0220 FAX # (301) 417 - 9069 March 14, 2007 Mr. David Waitt American Telecommunications Certification Body Inc. 6731 Whittier Ave McLean, VA 22101 RE: Comments of March 12, 2007 APPLICATION: UT650289BA8800DL Airorlite Communications Dear Mr. Waitt: Below are the comments that you have provided regarding the application for certification referenced above. Our responses to those comments are in bold italic. Many responses refer you to additional exhibit(s) which has been uploaded to the application folder at the ATCB website. Thank you for your attention. Please feel free to contact us for any additional information that you may require. Regards, Brian J. Dettling Documentation Specialist Michael Violette President WLL Project: 9520-2 1) (Number 6 from original comments) Booster rules cites: – Include exhibit or correspondence showing applicant was informed that boosters must meet all criteria stated in Sections 90.219 and 22.383 for related booster/inbuilding operations. NOTE: THIS APPEARS TO BE A CLASS B DEVICE UNDER 90.219, AND IF SO, SHOULD ADEQUATELY JUSTIFY AS SUCH. (Original response) The applicant is informed. See letter (Airorlite Pt90.219 Letter). Please add a reference to Part 90.219(d) to the letter. 90.219(d) is included below. (d) Class B broadband signal boosters are permitted to be used only in confined or indoor areas such as buildings, tunnels, underground areas, etc., or in remote areas, i.e., areas where there is little or no risk of interference to other users. Response to ATCB Comments FCC ID: UT650289BA8800DL 2 R. Thank you for the clarification. The letter has been updated accordingly. Please see Airorlite Pt90.219 Letter revised. 2) (Number 8 from original comments) There does not appear to be information to support that input drive level is at maximum input rating and maximum gain settings for all tests. Given this is basically and amplifier, this should be documented/justified....Additionally an explanation of what keeps the device from going into saturation should be provided...Generally amplifiers, booster, and repeaters must justify the levels used for test and document them as appropriate. See attached guidance as well... (Original response) The drive level was supplied by the customer. The optimal drive level was derived from empirical measurements provided by the customer on actual installations. A -50dBm level was found to represent the highest incoming stimulus signal. Is -50 dBm the maxim input level to both the uplink and the downlink? If not, please provide the maximum input level for each unit (UL & DL) R. Uplink: -60dBm; Downlink: -50dBm 3) (Number 9 from original comments) Power on grant should be clearly understood as either composite of multi-channels or per carrier. If power is composite include in comments field: "Power output listed is composite for multi-channel operation." It appears single channel power was tested...But how is output affected for multi-carriers given this device is clearly going to operate using 8 channels? Also, since the downlink would be classified as mobile and not fixed (i.e. in-building operation) MPE must be addressed with the maximum power and highest gain antenna. It is not clear from the report if the power out of this device is a per-channel power or a composite power. Depending on which power designation it is the actual output power of the device may exceed that listed in the excluded rf category and may in fact have to have measured MPE performed. See 10). Additionally, the output power was about 180 mW conducted per carrier, but the manual cites 25 dBm per carrier MINIMUM. Maybe this is due to difference of EIRP and conducted, but the way the manual cites this appears to be conducted. Therefore a difference between what was measured and expected may be present, which would also suggest drive levels were not properly set. (Original response) The device is intended to operate with eight (8) channels simultaneously. The uplink and downlink are rack-mounted equipment with fixed antennas. Mobile evaluation does not apply. The cutsheet originally supplied by the client mistakenly cited 25dB MINIMUM. A new sheet (52500-FCC_03_06_07R2 Model (1)) reflects the actual which states 25dB MAXIMUM. The composite output power is limited to 31dBm through AGC in the amplifier. See 50289DL Block Diagram 3.07 Please provide additional documentation outlining the 31 dBm limitation. Where is this limit specified and / or set in the hardware. It is apparent from examining the initial block diagram provided that the maximum output is approximately 31 dBm, but for purposes of determining correct RF Exposure parameters, the limit needs to be well documented. Additionally, with reference to the 25 dBm issue above, the user manual still references 25 dBm MINIMUM. Please correct R. The User Manual has been corrected. Please see “50289DL User Manual Rev 2”. From the client: I reference you to the drawing # 52100-01-35. If you go to the Power Amplifier module 52500-02-05 the output of this amplifier is AGC’d to a +31 dBm output level maximum. The Response to ATCB Comments FCC ID: UT650289BA8800DL 3 AGC is adjusted as follows. With an input level of -30dBm the output is adjusted to a +31 dBm level by the AGC pot. RF signal that is inputted to the power amplifier card is gained up and then sampled at the TAP. This sampled level is detected in the LTC 5505 IC. The output of this IC is a DC level that is proportional to the RF input. The Operational amplifiers that follow the detector has a threshold setting that is adjusted for the required output level (+31 dBm). When the DC level equals the setting the operational amplifier goes active and drives a second stage which interfaces to a PIN diode attenuator. The PIN attenuator has a range of 3 to 55 dB and adjusts the attenuation to reduce the RF input of the …

Model 50289 Bi-Directional Booster FCC ID: UT650289BA8800UL FCC ID: UT650289BA8800DL February 20, 2007 WLL PROJECT #: 9520 This report may not be reproduced, except in full, without the prior written consent of Washington Laboratories, Ltd. RF Exposure Evaluation Document 9250-MPE FCC ID: UT650289BA8800UL FCC ID: UT650289BA8800DL RF Exposure Test Report Washington Laboratories, Ltd February 2007 1 Maximum Permissible Exposure Test Report for FCC ID: UT650289BA8800UL FCC ID: UT650289BA8800DL 1.0 Introduction This report has been prepared to show compliance with the RF exposure requirements as defined in FCC §1.1307. 1.1 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable and are defined as follows: Fixed Installations: fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. Mobile Devices: a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. Portable Devices: a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). For this report the Airolite Communications Inc Booster with 7.1 dBi antenna is under consideration. The FCC also categorizes the use of the device as based upon the user’s awareness and ability to exercise control over his or her exposure. The two categories defined are Occupational/ Document 9250-MPE FCC ID: UT650289BA8800UL FCC ID: UT650289BA8800DL RF Exposure Test Report Washington Laboratories, Ltd February 2007 2 Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are defined as follows: Occupational/Controlled Exposure: In general, occupational/controlled exposure limits are applicable to situations in which persons are exposed as a consequence of their employment, who have been made fully aware of the potential for exposure and can exercise control over their exposure. This exposure category is also applicable when the exposure is of a transient nature due to incidental passage through a location where the exposure levels may be higher than the general population/uncontrolled limits, but the exposed person is fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. Awareness of the potential for RF exposure in a workplace or similar environment can be provided through specific training as part of a RF safety program. If appropriate, warning signs and labels can also be used to establish such awareness by providing prominent information on the risk of potential exposure and instructions on methods to minimize such exposure risks. General Population/Uncontrolled Exposure: The general population / uncontrolled exposure limits are applicable to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Members of the general public would come under this category when exposure is not employment-related; for example, in the case of a wireless transmitter that exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not considered sufficient to allow the device to be considered under the occupational/controlled category, and the general population/uncontrolled exposure limit…
