APPLICANT: ERICSSON INC.FCC ID NO: AXATR-409-A2 Exhibit 2A Para. 22.919, Electronic Serial Numbers Protection Against Unauthorized ESN and Firmware Upgrades The Electronic Serial Number (ESN) bits in this OEM module are encoded and spread over various non-sequential memory locations in order to prevent detection and modification. Once the factory has programmed the ESN, the mobile firmware cannot overwrite or alter the ESN memory locations. Both the ESN host and the operation systems components are permanently mounted to the mobile in order to prevent removal and misuse. Unauthorized attempts to alter the mobile’s firmware will cause the unit to become inoperable. ©1999 Ericsson Inc.

December 20, 1999 Federal Communications Commission Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21406 Attention:Equipment Authorization Branch Subject:Certification for FCC ID: AXATR-409-A2 Gentlemen, Ericsson Inc. requests certification (type acceptance) for the AXATR-409-A2. This OEM module transceiver is designed as a mobile for use in the AMPS/DAMPS cellular telephone system operates in the 800 MHz Domestic Public Cellular Radiotelephone Communications Services per Subpart H of part 22 and operates in the 1900 MHz Domestic Public Cellular Radiotelephone Communications Services, as per Part 24. When operating in the 1900 MHz range, DAMPS technology will be employed. This OEM module meets the requirements of IS-137A for operation in cellular systems. This OEM module is similar to previously type accepted FCC ID: AXATR-400-A2. Ericsson requests an exclusion from routine RF exposure measurements based on the discussion presented in Exhibit 11, RF Exposure Evaluation, and communications with Kwok Chan on 5/18/99. The primary reason for this request is due to hardware limitations of our burst mode making MPE evaluation infeasible because the module does not have a normal operating mode that would support the duration of an RF exposure evaluation. We have included specific instructions and warnings in Exhibit 8, OEM Interface Manual, regarding minimum separation distance, maximum antenna gain, and that use as a portable transmitter will require separate FCC approval for SAR compliance. Ericsson Inc. requests confidentiality under 47 CFR 0.459 for the following exhibits listed: Exhibit 4Block Diagram Exhibit 5Schematic Diagrams Justification of this request is that in order to facilitate the circuit miniaturization of the AXATR-409-A2, proprietary techniques were implemented in the transmitter, receiver, and baseband circuitry. To protect Ericsson’s competitive advantage on these proprietary techniques, we request the above listed exhibits be held as confidential and withheld from the Public Information File. Sincerely, Rick Timmons Tel No: (919) 472-1538

APPLICANT: ERICSSON INCFCC ID NO: AXATR-409-A2 Exhibit 12APage 1 of 3 ©1999 Ericsson Inc. CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.1033 (b)(4), (c)(10) (10)FREQUENCY STABILIZATION A temperature compensated crystal oscillator (U4) provides a 19.44 MHz reference frequency signal for the transmitter and receiver frequency synthesizers. This reference frequency is internally compensated to be within ±2.5 ppm over the temperature range of -30°C to +75° C. Upon power-up, the receiver searches and acquires a base station signal, and it adjusts the reference oscillator frequency to align itself to the high accuracy time base of the base station. The transmitter does not engage until after the receiver synchronizes to the base station. (11a)ATTENUATION OF SPURIOUS EMISSIONS The 800 MHz band transmitter frequency is obtained from mixing a phase locked VCO operating from 979.53 MHz to 1004.49 MHz with a 155.52 MHz signal. The 155.52 MHz signal is obtained by phase locking an oscillator to the VCTCXO output. The 800 MHz band receiver frequency is obtained by dual conversion. The first conversion is obtained by mixing the incoming signal with the 979.53 MHz to 1004.49 MHz VCO to a first IF frequency of 110.52 MHz. The second conversion mixes the IF frequency with a phase locked VCO at 110.4 MHz to obtain the second IF frequency of 120 kHz. All VCO’s are phase locked to the reference VCTCXO. The 1900 MHz band transmitter frequency is obtained from a 1002.765 to 1032.735 MHz synthesizer mixed with a 155.52 MHz signal. The result is then mixed back with the 1002.765 to 1032.735 MHz VCO signal to produce 1850.01 to 1909.95 transmit signal. The 1900 MHz band receiver frequency is obtained by dual conversion. The first conversion is by mixing the incoming signal with the doubled 1020.285 to 1050.255 MHz synthesizer to create a first IF of 110.52 MHz. The second conversion mixes the IF frequency with a phase locked VCO at 110.4 MHz to obtain the second IF frequency of 120 kHz. All VCO’s are phase locked to the reference VCTCXO. As a result of the above circuitry, the spurious signals are transmitter harmonics, reference oscillator 19.44 MHz harmonics, the local oscillators and the microprocessor clock. The use of multi-layer printed circuit boards, with signal tracks between ground planes, for the radio as well as for the logic areas reduces the radiation to a minimum. Ceramic resonator bandpass filters for the duplexer attenuate conducted transmitter harmonics, reference oscillator and local oscillator signals. A bandpass filter in the receiver front end attenuates the local oscillator signal further. Additional suppression of radiation is achieved by shielding and key isolation between circuits. (11b)LIMITING MODULATION The modulation for the transmitter is produced inside a Digital Signal Processing integrated circuit. The modulation limiting is therefore controlled by an algorithm inside this chip. The limit is preset at the factory and cannot be changed thereafter. ATTENUATING HIGHER AUDIO FREQUENCIES The DSP chip provides an audio filter with a 120 log (f/3000) response, f=3K to 20KHz. APPLICANT: ERICSSON INCFCC ID NO: AXATR-409-A2 Exhibit 12APage 2 of 3 ©1999 Ericsson Inc. Manchester encoded data signals are filtered prior to transmission by a four-pole lowpass filter providing an attenuation of 24 dB/Octave above 20 kHz. The signal produced by the DSP chip is a differentially shifted PI/4 QPSK signal for the digital system and a FM signal for the analog cellular system. These signals are fed through a three-pole lowpass filter with a 3 dB down cut-off frequency of 25 kHz to limit the adjacent channel energy in the digital mode. CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.1033 (b)(4) (11c)OUTPUT POWER CONTROL A loop circuit under supervision of the logic sets the output to any of the eleven power levels. A digital word is transmitted to the gain control amplifier for output power adjustment. A detector at the output of the power amplifier module senses the RF energy present and sends a corresponding DC voltage to the digital logic circuitry. Upon receiving a command to set power level from the handset or from a base station the microprocessor sends a predetermined word to the ALC amplifier. The output detector voltage is then read by the microprocessor and compared to a preset value. If the detector voltage is outside the allowed tolerance an adjustment is made to the gain-controlled amplifier to bring the detector voltage into the proper range. (12)DIGITAL MODULATION TECHNIQUES The NRZ data stream is transformed to 10kbps Manchester encoded data in such a way that each NRZ binary one is transformed to a zero-to-one transition, and each NRZ binary zero is transformed to a one-to-zero transition. The Manchester encoded data stream is filtered before being applied to the modulator. Direct binary frequency shift keying is used. A binary one into the modulator corresponds to a normal peak frequency deviation of 8kHz above the carrier frequency and a zero corresponds to a nominal peak frequency deviation 8 kHz below the carrier frequency. (12a)DESCRIPTION OF PI/4 DQPSK The modulation method used for the digital mode is known as PI/4 shifted differentially encoded Quadrature Phase Shift Keying. Eight distinct phase states are possible. The signal information is differentially encoded; symbols are transmitted as changes in phase rather than absolute phases. Transition of phase which would result in a zero amplitude momentarily are not allowed. APPLICANT: ERICSSON INCFCC ID NO: AXATR-409-A2 Exhibit 12APage 3 of 3 ©1999 Ericsson Inc.
