BTS-4000RM Installation and Maintenance Section 5 March 14, 2007 Technical Support 5-2 PRELIMINARY Frequency Per BCCH ARFCN RBW 30 kHz (See Note below) VBW 10 kHz Ref Level +45 dBm Sweep Auto Video Average On (100 samples) Note - This measurement must be taken in a 30 kHz RBW in case an alternate channel local carrier is nearby the BCCH, which would then give an artificially high reading if 300 kHz RBW were used. 4. If the BTS is not turned on, turn on the circuit breakers. The BTS will boot up and receive the MIB download, activating the BCCH channel. 5. After the BTS has booted, verify that the BCCH is at the correct frequency by observing the spectrum analyzer and correlating the center frequency with the ARFCN for RF 0. Refer to Appendix E to obtain the BTS transmit frequency. 6. Use the spectrum analyzer’s Marker in Peak mode, and measure the RF output power in dBm at the TX Monitor port. Since the Tx Monitor port is inclusive of the HPA to Filter coax and the Filter loss, it should be +43.0 dBm ±0.5 dB. 7. If the level measured at the TX Monitor output is +43.0 dBm ±0.5 dB, this procedure is complete. If you performed this procedure as part of the initial BTS installation, return to Section 3.4 and fill out the BTS-4000RM Installation Quick Checklist form. If the level measured at the TX Monitor output is too high or too low, connect a console to the BTS-4000RM BPU as described in Section 2.1, and then perform the following steps: a) Use the rfStuff command to view the current attenuation level. Following is an example of the rfStuff output: rfStuff 0 1 2 3 ==================== ============ ============ ============ ============ bdxState: Operational NotDetected NotDetected NotDetected BDX board rev: 810 0 0 0 BDX Ctrl FPGA rev: 29 0 0 0 BDX TDM FPGA rev: 18 0 0 0 BDX ModelType: GSM 850 ???? ???? ????

The settxlevel command is used by AirNet manufacturing and in the field to adjust the BDX transmit level to match the gain of the HPA and other components in the transmit path. The default is 4.0 dB of attenuation, but the current level is displayed with the rfStuff command. The setting can be adjusted from 0 dB to 15.5 dB in 0.5 dB steps. The new transmit level attenuation takes effect immediately and is stored in BDX flash, so it stays in effect after reboots. The syntax for the settxlevel command is shown below: settxlevel <board num>, “<attenuation in dB>” board num = BDX board number (0 to 3) attenuation = Amount that the BDX attenuates the transmit path (from 0.0 to 15.5 dB in 0.5 dB steps). 4.0 dB is the default in BDX. Put double-quotes around the attenuation value, as shown. Note - The attenuation level is in dB and must have one digit after the decimal point (i.e., 5 must be entered as 5.0). Following is an example of how the settxlevel command would be used if the BTS-4000RM output were 1 dB too hot: AirNet BTS->settxlevel 0, “5.0” Writing Flash BDX Transmit RF level to 5.0 Current BDX Transmit RF level is 4.0 Setting BDX Transmit RF level to 5.0 Successfully wrote RF Tx Attenuation 5.0 to flash value = 0 = 0x0 AirNet BTS-> 8) Repeat Steps 6 and 7 until the output is +43.0 dBm ±0.5 dB. 9) Record the final Tx output level.

The AirNet BTS uses AirNet’s patented broadband technology to achieve its compact size and high capacity. The AirNet BTS is designed around the philosophy of the software- defined radio. AirNet’s broadband technology comprises AirNet’s software defined radio implemented with its Digital Signal Processors (DSPs) and Broadband Digital Transceiver (BDX). These components can be software-configurable and are programmed with modulation type, RF channel bandwidth, channel spacing, and frequency, and the parameters of cellular radio signals. AirNet’s broadband technology eliminates the need for a bank of cavity filters and RF combiners that are traditionally required with narrowband systems. Transmitted signals are combined digitally into a single broadband signal that is upconverted to the appropriate RF band by the BDX and amplified by an external highly linear, multi-carrier amplifier. The AirNet BTS-4000RM can combine up to 12 TRXs. Likewise individually received RF carriers are digitally filtered, which provides significantly more flexibility and FCC ID: MZKBTS4000-850 AirNet Communications Corporation - Proprietary Page 2 of 4 control for out-of-band signal rejection than analog filtering used in traditional BTS transceivers. All software components (source, libraries and executables) of the AirNet software defined radio are tightly controlled using mature industry-standard software configuration management practices. All versions of code released for customer use are archived in an unwritable state and retained for the duration of product life, and can be readily compared to any other version. These archive versions are also backed up and stored off-site for disaster recovery. Subsequent changes to the baseline version of AirNet software delivered for initial testing by the FCC will be managed according to the FCC rules and regulations for permissive changes. Per past direction from the OET office at the FCC (see FCC ID: MZKBPU2000-1900), this application covers the RF transceiver portion of the BTS; it does not include the high power amplifiers (HPA) that are sold with the product. This is a result of AirNet’s ability to use different amplifiers from different vendors with the same base BDX and digital BTS hardware. Each amplifier type has it’s own Part 22 certification. Therefore, this application is written for the RF output of the BDX - the HPA and the post HPA RF duplexer/filter have been bypassed for all conducted transmit tests shown herein. This application refers to the complete BTS product with an HPA when discussing means for limiting output power and when referring to power limitations for channels at the band edge. As in the previous application, ARFCNs adjacent to the band edge are limited in the AirNet BTS to a power of 2 Watts or less. It has been shown previously that a 2 Watt GMSK or 8PSK modulated carrier centered 200 kHz from a band edge meets the FCC requirements for out of band spurious emissions. Total power out of the BTS with an HPA will be governed by the equipment authorization granted for the HPA and other applicable FCC regulations as described in Part 22. Tune-up Procedure The parameters for programming the transceiver synthesizes are stored in a file contained in flash memory on the BTS. This file is configured at the factory and the system user cannot change it. These parameters determine the receiver and transmit frequencies and their separation. The transceiver has a 5 MHz receiver and a 5 MHz transmit bandwidth at this base frequency. The parameters are downloaded to the flash non-volatile memory during BTS installation based on the frequency plan for that particular licensee. The BTS transceiver will automatically tune to these frequencies at power-up. This data, or list of tuning frequencies, is required in order for the base station to transmit; if lost or corrupted the system will not transmit. There is no user accessible way of retuning the BTS. Means for Frequency Stabilization The frequency reference for the BTS is an extremely stable 13 MHz signal supplied by the Rubidium Oscillator module. The 13 MHz signal is then used to phase lock a 91 FCC ID: MZKBTS4000-850 AirNet Communications Corporation - Proprietary Page 3 of 4 MHz Voltage Controlled Crystal Oscillator or VCXO. The 91 MHz signal is then used by the transmit IF and RF synthesizes to produce the local oscillators required for the upconversion. Means for Harmonic Suppression Conducted Harmonic Suppression- The upconverter stage contains a SAW band-pass filter centered at 836.5 MHz with a 25 MHz bandwidth. This SAW filter significantly reduces the level of out of band spurious emissions and transmitter harmonics. In addition, there is a duplexer filter connected in the transmit path after the output of the high power amplifier. This is to ensure that any certified amplifier can be connected between the transceiver output and the duplexer filter input and continue to meet the requirements. The duplexer is a cavity based 8-pole filter tuned to the GSM 850 MHz transmit band (824 to 849 MHz). This filter provides additional attenuation of spurious emissions generated or passing through an amplifier (80 dB out-of-band suppression). Note that the spurious emission…

The transceiver has a 5 MHz receiver and a 5 MHz transmit bandwidth at this base frequency. The parameters are downloaded to the flash non- volatile memory during BTS installation based on the frequency plan for that particular licensee. The BTS transceiver will automatically tune to these frequencies at power-up. This data, or list of tuning frequencies, is required in order for the base station to transmit; if lost or corrupted the system will not transmit. There is no user accessible way of retuning the BTS. Means for Frequency Stabilization The frequency reference for the BTS is an extremely stable 13 MHz signal supplied by the Rubidium Oscillator module. The 13 MHz signal is then used to phase lock a 91 MHz Voltage Controlled Crystal Oscillator or VCXO. The 91 MHz signal is then used by the transmit IF and RF synthesizes to produce the local oscillators required for the upconversion. Means for Limiting Power The dynamic range of the wideband digital signal coming to the transceiver from the DSP board is set in an initialization file that is automatically downloaded at system power-up. This value is chosen to give the maximum power out of the transceiver for the desired maximum number of carriers, while preventing the digital output from overflowing and thus clipping the signals. The base station controller has the capability, through software download, of changing the combiner gain value to yield a lower maximum power level out of the transceiver. The level can only be decreased, not increased. The granularity of the control is in 1 dB steps. There are no other methods for a system user to vary the power level. Per the PCS-1900/850 Air Interface Specification, the system provides 15 levels of dynamic power control in steps of 2 dB each. This variable attenuation is used by the power control algorithm running on the digital signal processor boards to optimize the power level of the signal from the base station to the mobile handset. (Only use as much power as necessary to achieve an acceptable signal to noise ratio (SNR).) When a traffic channel is first turned on, it is at maximum attenuation, i.e., 30 dB below maximum power. The power control algorithm will then continually optimize this level based on the strength of the received mobile signal. This power adjustment mechanism is automatic and implemented in DSP software. All high power amplifiers that will be used will shutdown if their input signal level is too high, if the VSWR at the output port is too high, if the output power is too high, or if a number of other error conditions occur. This ensures that the BTS will not transmit at power levels higher than authorized should a system equipment failure occur.

The unit consists of a baseband processing unit (BPU) module and a high power multi-carrier amplifier (HPA) module. This unit provides high capacity GSM and EDGE services in a compact form factor. EUT Operation and Exercising: The BPU was configured using test functions to produce GSMK or 8PSK modulated carriers. The data streams consist of pseudo-random data. The BPU then upconverts the baseband signal to the final RF frequency. The upconverted signal is then sent to the multi-carrier amplifier module for amplification for over the air transmission. All non-RF ports were either terminated or configured for loopback.
