Characteristics used for this typical MPE are shown in Table 9.1. Each PWAN Base Station installed will include an MPE analysis with data and required paperwork being stored and filed with the FCC as per regulatory requirements. 9.1.3Typical MPE Test Results The PWAN Base Station meets the required FCC regulatory part 24 requirements as shown in the following figures. Figure 9.1 illustrates horizontal distance versus power density, while Figure 9.2 provides graphical data of horizontal distance versus uncontrolled MPE. As shown in Table 9.2, a typical PWAN Base installation meets FCC MPE requirements. Per regulations, all installations will include an MPE analysis with data being stored and filed appropriately.

Form 731 Confirmation Number EA95308 FCC ID: OF2FWBASE To Whom It May Concern: On August 31, 1999, AT&T Wireless Services, Inc. (“AWS”) submitted electronically, an FCC Form 731 application for equipment code PCB, Licensed Base Station For Part 24. At the time of filing AWS inadvertently duplicated the first 3 digits of the FCC ID number. AWS hereby respectfully requests that the FCC ID for its application (Confirmation number EA95308) be corrected to read “OF2FWBASE.” Should there be any questions please contact Lisa M. Volpe at 202-416-6519.

RESPONSE TO FCC QUESTIONS FCC Application Processing Branch Re:FCC ID OF2FWBASE Applicant:AT&T Wireless Services, Inc. Correspondence Reference Number:10275 731 Confirmation Number:EA95308 Date of Original E-Mail:10/20/1999 1. While you listed an output power of 50 W, measurements indicate a peak output of 13.8 W. Given the "1 dB" (20%) policy, I can grant a value of up to about 17 W, based on this measured value. Please address. The testing was completed at the antenna terminal on one sector of the Base. Therefore this is acceptable for each sector of the Base. We would like the grant to list the output power at approximately 43 dBm pk and 35 dBm avg (this meets our tested 7 dBm peak/avg ratio). 2. What is the actual tuning range of the EUT (low channel center frequency thru hi channel center frequency)? This is what is actually listed on the grant. Were the low and hi channels the ones tested for bandedge compliance? Yes, the high and low were tested for compliance. Each sector uses a 1 Mhz band.......the center frequency of the entire 5 Mhz band is 1948 Mhz (this is what we would like the grant to say).

To:Greg Czumak [email protected] FCC Application Processing Branch Re:FCC ID OF2FWBASE Applicant:AT&T Wireless Services, Inc. Correspondence Reference Number:10998 731 Confirmation Number:EA95308 Date of Original E-Mail:12/13/1999 1. As I stated in my last e-mail, having measured 13.8 W output power, I can grant up to 17 W under our policy. You state that you would like the grant to list 20 W (43 dBm). Measurement data does not support this value. Either a value between 13.8 and 17 W will be listed, or you must submit new test data to support your request of 20 W. Please address. Sorry about the confusion, please list at 42.3 dBm or 17 W. 2. You did not answer my second question completely. I asked what the actual tuning range of the EUT is, center frequency of the lowest available 1 MHz "sector" through the center frequency of the highest available 1 MHz "sector". This is the range that will be listed on the grant. To what "5 MHz band" do you refer in your response? Are you referring to Frequency Block D (1945-1950 MHz)? Yes, its Frequency Block D...with a center frequency tuning range of 1946 MHz - 1949 MHz. Thank you for your time and effort.

Throughout this document, all depictions of test configurations utilize a common set of interfaces. These interfaces are described in detail in Chapter 7, “Operational Description” of this document. The name and purpose of each interface is summarized in Table 11.1— below: Table 11.1—PWAN Interface Definitions 11.1.2 Base Station Frequency Stability vs. Temperature 11.1.2.1—Applicable FCC Rules Parts FCC Subpart 2.995 - Measured over the temperature range of -30 to +50 C. Frequency measurements shall be made at the extremes and at intervals of not greater than 10 degrees C throughout the range. Only the frequency determining portions of the transmitter need be subjected to this test. FCC Subpart 24.236 - The frequency stability shall be sufficient to ensure that the fundamental emission stays within the authorized frequency block.

Either Synchronization Card is capable of functioning in one of the following three operational modes: Oscillator operating in GPS Locked Mode: During normal operation, the frequency of the 10 MHz oscillator is disciplined by GPS to an accuracy of approximately ±0.005 PPM. Oscillator operating in GPS Holdover Mode: In the event that GPS signals are lost (due to an antenna or GPS receiver failure), the 10 MHz oscillator will utilize the most current correction data obtained from the on-board GPS receiver to maintain an accuracy of approximately ±0.02 PPM over a 24 hour period. Oscillator operating in GPS Free-Run mode: In the event that GPS is completely unobtainable, the 10 MHz oscillator will free-run with an accuracy of approximately. ±0.2 PPM. The 10 MHz disciplined oscillators on the primary and redundant Synchronization Cards serve as the main frequency-determining element in the Base Station. Any frequency error present in the 10 MHz output of the Synchronization Cards will create a corresponding frequency error in each transmitted OFDM tone at the Base Station operating frequency. The Base Station also contains its own low stability (approx. 5 PPM) 10 MHz reference oscillator. This internal oscillator is phase-locked to the active Synchronization Card for the purpose of minimizing the effects of reference oscillator phase noise. The Base Station software is designed to disable RF output power in the event that both of the Synchronization Cards fail (or are not present). As a result, the Base Station will not transmit while using the internal oscillator as its 10 MHz reference. 11.1.2.3—Test Methodology The Synchronization Card under test was placed into a Screening Systems, Inc. model QRS-410T thermal chamber (refer to Figure 11.1). A Hewlett/Packard 53132 frequency counter was used to monitor the Base FCC Regulatory Test Report 11-694 AT&T Wireless Services FCC Type Acceptance Application 10991 Rev. 1.0 7/8/99 output frequency of the DUT. A Hewlett-Packard 5071A cesium beam primary standard was utilized as a precision frequency reference for the 53132A frequency counter. The frequency counter resolution was set to 0.001 Hz. The frequency accuracy of the 10 MHz oscillator was tracked over the temperature range of -30 to +50 Celsius. During this test the thermal chamber “stair-stepped” from -40 to +60 degrees Celsius in temperature increments of 10 degrees Celsius. The thermal chamber’s sensing thermocouple was attached to the Synchronization Card about 10 cm from the ovenized oscillator to assure that the DUT was kept to within ±5 degrees Celsius of each pre-determined thermal step. The chamber held each thermal step for 15 minutes. The total run time was three hours per test. The frequency stability of the DUT was measured over temperature in each of the three operating modes.

In this case, per FCC Part 15, subpart 15.207. Measurements shall be made at the EUT azimuth and antenna height such that the maximum radiated emissions level will be detected. This was accomplished using both an automated 360 degree turntable and 1 to 4 meter height antenna positioners. Sixteen azimuth cuts at 22.5 degrees and 1 to 4 meter antenna scans in both polarizations were utilized. The PWAN Base was setup in a typical field configuration, as shown in Figure 12.1—, consisting of the PWAN Base being in the center of the turntable. Proper interconnecting cable was utilized from the PWAN Base to the system power supply. All radiated emissions testing was completed in three configurations; 1.) 16 voice calls on the same time slot in the same sector. 2.) eight voice calls per sector. 3.) eight voice /high-speed data calls per sector. Testing was completed from 30 MHz to 26 GHz. When testing close to or over the fundamental frequency range, a notch filter tuned to the Remote Unit and PWAN Base Station fundamental frequencies was utilized to prevent receiver radio frequency overload and/or damage. To complete the calls, a test fixture tilizing a rack of sixteen (16) Remote Units (RU’s) with two telephones per RU was established. Figure 12.10 shows the RU Test rack used to load the Base. The rack was designed to hold up to 16 remote units together with all power, RF, and telco connections. This design was necessary in order to load the base with the maximum amount of calls on the same time slot and sector 16 remote units, two lines each for a total of 32 calls).
