04/27/011/3 FCC ID: 9900RT Operational Description Alcatel 9900 LMDS Terminal Station This is a summary of the operational description for the Alcatel 9900 LMDS Terminal Station transmitter as required for type certification under FCC Part 101. 04/27/012/3 System Overview The Alcatel 9900 is a Local Multipoint Distribution System (LMDS) that provides transport of packet data and telephony services between a central hub (base station) and multiple subscribers (terminal stations). The system operates in the 28000-28350 MHz and 29100-29250 MHz LMDS bands for downstream communications (hub to subscriber). The system operates in the 27500-28000 LMDS band for upstream communications (subscriber to hub). The base station is composed of two units, an indoor Digital Base Station (DBS) and an outdoor Radio Base Station (RBS). The DBS receives digital ATM and E1/T1 signals and modulates them to an IF TDM signal that is sent to the RBS. The RBS converts the IF signal to the downstream RF transmit frequency. The RBS receives burst TDMA signals from the terminal stations and converts them to IF receive signals. The DBS demodulates the IF signals and generates to digital data to be returned on the ATM and E1/T1 ports. Each RBS provides service for one quadrant of the LMDS cell. Each DBS provides support for up to four RBS transceivers for full cell coverage. The terminal station is also composed of two units, an indoor Network Termination (NT) and an outdoor Radio Termination (RT). The RT receives the RF signal from the base station and converts it to the receive IF frequency. The NT demodulates the IF signal and recovers the digital data to be provided to the subscriber interfaces. The NT also receives the digital data from the subscriber interfaces and modulates it into the transmit IF signal. This signal is only generated for specific time periods as authorized by the base station. The transmit IF signals are converted to the upstream RF frequency by the RT and transmitted as a narrow beam signal to the base station. Terminal Station Receiver Description The terminal station must first lock to its assigned base station to receive configuration provisioning. The terminal station transmitter is inhibited until the signal is locked and this information is received. The waveguide diplexer in the RT directs the receive RF signals to receive LNA. The receive signals are amplified by the LNA and mixed to the receive IF frequency. This frequency varies depending on the assigned RF channel. The mixer LO is synthesized from a VCO that is phase-locked to a free-running 13 MHz TXCO. The IF signals are amplified by a programmable fixed gain amplifier to compensate for RF path distance and IF cable losses. This gain is programmed into the RT during installation. The NT receives the IF signals and demodulates them. Information about the receive signal level and frequency error is retained and used to adjust the transmit IF power and frequency. The digital data packets from the demodulator are buffered and routed as needed to the subscriber Ethernet and E1/T1 interface ports. 04/27/013/3 Terminal Station Transmitter Description The NT receives Ethernet packet data and E1/T1 telephony data and multiplexes it together into a TDMA data packet. Reed-Solomon error correction is added to the TDMA data. The data packets are only generated during time periods that have been assigned by the base station. No data is transmitted when the receiver is not locked to the base station. The data packets are then Viterbi encoded and QPSK modulated to generate a 43 MHz IF signal at 5.375 Mbaud. The I/Q modulator uses digital shaping filters with an α of 0.25. This results in a 6.72 MHz full power bandwidth signal. The actual IF frequency is offset to correct for LO error in the RT. This error is determined from the frequency error in the receive IF signal and from commands from the base station. The modulator IF is then mixed to a second IF frequency of 520-700 Mhz. The IF frequency varies depending on the assigned RF channel of the terminal station. The IF signal is amplified by a variable gain amplifier to correct for path fading. The gain level is determined by a combination of the error detected in the receive signal level and commands from the base station. The signal is sent on a coaxial cable to the RT along with 24 VDC for power and internal sub-carriers for RT communication. The RT filters the transmit IF signal to isolate it from the receive IF signal and then amplifies it using programmable fixed gain stages to compensate for cable and path distance losses. This gain is programmed into the RT during installation. It is then filtered and mixed to the final RF transmit frequency using the same LO as the receive section. The RF transmit signal is sent through a waveguide diplexer to an integral antenna. This is a 3° parabolic antenna that has 34.5 dB of gain.

Page 1 of 1 March 20, 2000 TO: Federal Communications Commission Office of Engineering Technology Laboratory FROM: Jeffrey L. Zwiebel Systems Development Staff Engineer Wireless Access SUBJECT: RF Exposure Calculations for FCC ID JF69928RT The 9928RT unit uses an integral parabolic antenna with a diameter of 26 cm. The antenna has a nominal gain of 34.5 dBi. The transmitter section of the 9928RT operates at a fixed gain over a nominal frequency range of 27500 to 27850 MHz. The RT gain is adjusted at installation to compensate for distance from the base station and for IF cable losses. The IF input level varies to compensate for fading conditions. The maximum RF output power under normal operating conditions is +12 dBm (16 mW). However if the RT fixed gain has not been properly set, the unit can be driven into compression with a maximum RF power output of +18 dBm (63 mW). Calculations for RF exposure are based on this condition. The maximum power density in mW/cm 2 for the near field of a parabolic antenna is W = (16 x P)/( π x D 2 ) where P = average transmitter power in mW and D = antenna diameter in cm. This results in a near field power density of W = (16 x 63)/ ( π x 33 2 ) = 0.295 mW/cm 2 . This level is less than the maximum uncontrolled exposure limit of 1 mW/cm 2 for the general population as listed in Table 1 of 47 CFR Part 1.1310. Therefore the transmitter is safe for all distances outside of the interior of the antenna dish. The antenna on the 9928RT has a front cover that is sealed to the dish, preventing normal access to the interior. A statement that the equipment meets the RF exposure limits of 47 CFR Part 1.1310 is included on the FCC ID label for the 9928RT.

822801/15 01/19/00 2:16 PM FCC ID: 9900RT Test Report Alcatel 9900 LMDS Terminal Station This is a summary of the test measurements performed on the Alcatel 9900 LMDS Terminal Station transmitter as required for type certification operating under FCC Part 101. Also included are measurements required for conformance with FCC Part 15 as a Class B unintentional radiator. 822802/15 01/19/00 2:16 PM Part 2.1046 - RF Power Output The Alcatel 9900 Terminal Station is composed of two separate assemblies, an indoor Network Termination (NT) and an outdoor Radio Termination (RT). The RT operates at fixed gain that is programmable to compensate for the distance from the base station and for losses generated in the cable between the RT and the NT. The NT uses a combination of the receive signal level and commands from the base station to adjust the IF levels sent to the RT. This forms an Automatic Transmit Powel Control (ATPC) loop that adjusts the RT transmit power to maintain a constant receive level at the base station. The ATPC has a dynamic range of 40 dB. The RT normally operates at a nominal level of -8 dBm when no fading conditions are present. DC power for the RT is supplied from the NT through the connecting cable. Internal regulator circuits in the RT generate the required bias currents and voltages for the transmitter devices. No operator adjustments are required other than to program the RT with the IF cable length and nominal path distance losses. The RT uses an integral 3° parabolic antenna. The transmitter power was measured with the antenna removed and a WR-28 to coaxial transition installed in its place. Since the transmitter is shut off if the NT is not connected to the base station, a 10 dB directional coupler (calibrated loss = 11.0 dB) is also installed. The transmitter power was then measured using an HP438A Power Meter with an HP8487A Power sensor.

Maximum required attenuation is 56 dB. Measurements are to be made referenced to a 1 MHz resolution bandwidth. The authorized bandwidth for the Base Station with emission designator 7M0D7W is 7 MHz. This translates into an attenuation mask defined by the following points: Frequency (MHz)Percent Attenuation (dB) -17.5-25056 -9.9-14156 -3.5-5019.5 3.55019.5 9.914156 17.525056 Test Setup: NT RBS/ DBS FSEK20 Spectrum Analyzer 10 dB Coupler +12 dBm +1 dBm RT The RT transmitter was set to its maximum nominal output and measured using the HP power meter to be +12 dBm. The transmit spectrum was then measured with a Rhode&Schwarz FSEK20 spectrum analyzer. The power into the spectrum analyzer (including measurement cable losses) was -6.4 dBm. Due to narrow spectrum bandwidth, a 3 kHz resolution bandwidth was used. The reference level was offset by 10log(3/1000) = 25 dB to reference it to a 1 MHz resolution bandwidth. This results in a reference level of -31.4 dBm. The measurement results are shown in Exhibit 1. 822804/15 01/19/00 2:16 PM Exhibit 1 - Modulation Characteristics 822805/15 01/19/00 2:16 PM Part 2.1049 - Occupied Bandwidth The FSEK20 Spectrum Analyzer has the capability to calculate occupied bandwidth from a measured spectrum. The analyzer was set up to measure 99% bandwidth, resulting in the measurement of 5.962 MHz as shown in Exhibit 2. Exhibit 2 - Occupied Bandwidth 822806/15 01/19/00 2:16 PM Part 2.1051 - Emissions at the Antenna Port Emissions removed from the center frequency by more than 250 percent of the authorized bandwidth are required by Part 101.111(a)(2)(iii) to be attenuated from the transmitter output power by 43 + 10log(Power in watts) decibels. For a +12 dBm transmit power, this results in an attenuation of 25 dB. Measurements are to be made using a 4 kHz resolution bandwidth. Since this is not a standard spectrum analyzer bandwidth, a resolution bandwidth of 3 kHz was used with the -6.4 dBm reference level offset by -1 dB. Measurement results are shown in Exhibits 3 and 4. Exhibit 3 - Emissions at the Antenna Port 822807/15 01/19/00 2:16 PM Exhibit 4 - Emissions at the Antenna Port The only significant spurious signal that was found is shown in Exhibit 4. This signal is within the allowed 25 dB attenuation limit. 822808/15 01/19/00 2:16 PM Part 2.1053/15.109 - Field Strength of Spurious Radiation Measurements for spurious radiation were taken as part of the CISPR testing performed by CETECOM ICT Services. These results are shown in Exhibits 5, 6, and 7.

Error in the local oscillator frequency or in the frequency of the base station signal cause an error in the receive IF frequency at the NT. The NT measures the error in the receive IF frequency and offsets the frequency of the transmit IF signal by the same amount. This cancels the error in the RT local oscillator when the transmit IF signal is mixed back to RF. Any remaining error in the transmit RF frequency is due to error in the signal transmitted from the base station. The base station uses the same LO for both the transmit and receive. Residual frequency error in the receive IF at the base station is detected and a co…

922721/18 03/17/00 6:10 PM FCC ID: 9900RT Test Report Alcatel 9900 LMDS Terminal Station This is a summary of the test measurements performed on the Alcatel 9900 LMDS Terminal Station transmitter as required for type certification operating under FCC Part 101. Also included are measurements required for conformance with FCC Part 15 as a Class B unintentional radiator. 922722/18 03/17/00 6:10 PM Part 2.1046 - RF Power Output The Alcatel 9900 Terminal Station is composed of two separate assemblies, an indoor Network Termination (NT) and an outdoor Radio Termination (RT). The RT operates at fixed gain that is programmable to compensate for the distance from the base station and for losses generated in the cable between the RT and the NT. The NT uses a combination of the receive signal level and commands from the base station to adjust the IF levels sent to the RT. This forms an Automatic Transmit Powel Control (ATPC) loop that adjusts the RT transmit power to maintain a constant receive level at the base station. The ATPC has a dynamic range of 40 dB. The RT normally operates at a nominal level of -8 dBm w hen at the maximum distance from the base station and no fading conditions are present. DC power for the RT is supplied from the NT through the connecting cable. Internal regulator circuits in the RT generate the required bias currents and voltages for the transmitter devices. No operator adjustments are required other than to program the RT with the IF cable length and nominal path distance losses. The RT uses an integral 3° parabolic antenna. The transmitter power was measured with the antenna removed and a WR-28 to coaxial transition installed in its place. Since the transmitter is shut off if the NT is not connected to the base station, a 10 dB directional coupler (calibrated loss = 11.0 dB) is also installed. The transmitter power was then measured using an HP438A Power Meter with an HP8487A Power sensor. RT part number:3CC10886AB Type design:solid state RT DC Power:+30 VDC nominal 12 W nominal DC powe…
