MOTOROLA, INC. July 24, 1998 Mr. Greg Czumak Federal Communications Commission Equipment Authorization Division 7435 Oakland Mills Road Columbia, Maryland 21046 Re:Request for Additional Technical Information, received by E-Mail on July 24, 1998, regarding pending Application for Type Acceptance, FCC ID: IHDT6YH1, [Correspondance ID: 2232]. Dear Mr. Czumak: In response to item 1 of the referenced request, to "Please submit the SAR report, electronically via the internet.", this has been uploaded as six files with the "Exhibit Type" of "RF Exposure Info." As we have reached agreement with Kwok Chan for past submittals, the files consist of the following: our report, a procedure document, and 4 data set files. The data set files are two for each antenna position (extended and retracted) showing the area and zoom scans for the test channel and ear position for which the highest SAR value was found for that antenna position. The report shows a tabular summary of measured SAR values for all twelve test conditions (low, middle, and high channel; left and right side; extended and retracted antenna position). In response to item 2 of the above request, to "Please indicate the EIRP of the EUT, based on the measured conducted output power of 1W and the antenna gain.", the 1W conducted output power indicated is during the transmit burst (this technology operates with a 1/8 duty cycle) and the maximum gain in any direction was found to be 4.0 dBi at mid channel with the antenna in the extended position. Therefore, maximum EIRP for this product would be 2.5W. Also, an error was discovered in the description of the battery system for this product in Exhibit 11. A corrected version of Exhibit 11 has been uploaded. I trust that this will satisfy the request and allow the Grant to be issued for this equipment. Please contact me by telephone at (847) 523-7373 or by facsimile at (847) 523-2350 if there are any further questions or additional information needed concerning this filing and/or this reply.

APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 1 PAGE 1 OF 7 Type Acceptance Requirements The information in this exhibit is in accordance with requirements for type acceptance as outlined in the FCC Rules and Regulations, CFR Part 2 Sections 2.983 - 2.999 and 47 CFR Part 24 Sections 24.52, 24.235 and 24.238. Section 2.983: Application for Type Acceptance (a) Name of Applicant: Motorola Inc., Motorola is also the manufacturer of the equipment described herein. (b)Identification of Equipment: IHDT6YH1 (c)Quantity Production: Quantity production is planned. (d)Technical Description: The transmit and receive equipment (FCC ID: IHDT6YH1) for which type acceptance is desired, is intended for use as a mobile station cellular transceiver in the broadband US PCS frequency region and is designed in compliance with the FCC Rules and Regulations Parts 2 and 24. (1) Types of Emissions: Designator 250KGXW The mobile station transceiver transmits a Gaussian Minimal Shift Keying (GMSK) modulated carrier having a BT product of 0.3. The bandwidth of a GMSK modulated carrier having a BT of 0.3 is 250 kHz (see EXHIBIT 2). This results in 250K for the first four characters of the emissions designator. GMSK is the same as Minimal Shift Keying (MSK) except that the NRZ data has been filtered prior to modulation. As a result, GMSK, like MSK can generally be thought of as frequency shift keying (FSK), or Offset Quadrature Phase Shift Keying (OQPSK), and can be modulated and demodulated using either of these techniques. Motorola's mobile station transceiver is based off of the OQPSK technique, which is a type of phase modulation. This corresponds to G, for Types of Modulation. APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 1 PAGE 2 OF 7 The mobile station transceiver uses a digital signal representing sampled, quantized voice or other audio information or command data to modulate the main carrier in a Time Division Multiple Access (TDMA) fashion. This corresponds to X for nature of modulating signals. The symbol 1 excludes time- division multiplex, and the other choices for digital modulating signals either state “Two or more channels containing quantized or digital information” or “Composite system with one or more channels containing quantized or digital information, together with one or more channels containing analogue information. The information transmitted is a combination of command data and telephony (sampled quantized voice or other audio signals). This corresponds to W for Types of Information Transmitted, defined as “Combination of above” which would be the combination of symbol D, “Data transmission, telemetry, telecommand”, and symbol E, “Telephony (including sound braodcasting)”. (2) Frequency Range This equipment is designed to transmit from 1850- 1910 MHz. This frequency range corresponds to Blocks A, D, B, E, F and C of the US PCS frequency band. (3) Range of Operating Powers The transmitter output power range is +0 dBm to +30 dBm. This range of output power is controlled to sixteen discrete levels in increments of 2 dBm. This is a dynamic adjustment carried out under the command and supervision of the cellular base station and is used to control the uplink power from the mobile within a cell as the position of the mobile changes. Transmit power tuning adjustments are made at all sixteen levels: Refer to EXHIBIT 7. APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 1 PAGE 3 OF 7 (4) Maximum Power Rating (Sec. 24.232) In no case may the peak output power of a mobile station transmitter exceed 32 dBm. (5) Applied Voltage and Currents into the Final Amplifying Device: Refer to EXHIBIT 6. (6) Function of Active Devices: Refer to EXHIBIT 5. (7) Complete Circuit Diagrams: Refer to EXHIBIT 4. (8) Instruction Manual: Refer to EXHIBIT 15. Because the mobile station transceiver is based on the design of a European GSM model, and, more specifically, the user functionality and features are nearly identical to this GSM model. The user instruction manual that is included in this submission is a copy of the GSM manual and should be viewed as a preliminary version user manual in state very near that of the final version intended to ship with the equipment. If necessary, when available, the final version can be provided upon request. (9) Tune-Up Procedure Several adjustments are performed on the transmitter at a radio level before the mobile station transceiver is fully operational. Refer to EXHIBIT 12. (10) Means for Stabilizing Frequency: Refer to EXHIBIT 3. (11) Means for Suppressing Spurious Radiation Spurious and harmonic suppression is achieved through multiple means. 1. Radio Architecture: APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 1 PAGE 4 OF 7 a. Proper selection of local oscillator frequencies and intermediate frequencies (IF) to minimize spurious products. b. Minimization of broadband noise both in- band and out-of-band through the combination of gain/noise figure architecture in the transmitter exciter stages and proper control of the transmitter's gain. 2. Physical Construction and Circuit Design Techniques: a. Sources of spurious radiation such as frequency source circuitry and high gain circuitry within the equipment are assembled under grounded conductive cans on the circuit boards forming a localized shielded enclosure within the unit. b. Physical separation of frequency sources from high gain circuitry. c . Multilayer PC boards allow use of stripline for routing signals. (12) Means for Limiting Modulation The carrier is modulated with Gaussian Minimal Shift Keying (GMSK) having a BT product of 0.3. By definition, the peak frequency deviation of GMSK is one-fourth of the bit rate, or 270.833/4 = 67.7083 kHz. There is a theoretical phase trajectory that any given bit stream should ideally follow over the period of one time slot. However, imperfections in the modulation process can introduce errors which produce variations from the ideal trajectory. By design, the transmitter will follow …

APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 12 PAGE 1 OF 3 EXHIBIT 12 Transceiver Adjustments Exhibit Summary: EXHIBIT 12 contains information pertaining to radio level adjustments that are performed during the manufacturing process. Contents: Frequency Adjustment...............................................................2 Transmit Output Power Adjustment.......................................2 Receive I and Q Balance .............................................................3 Receive Audio Level Adjustment.............................................3 APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 12 PAGE 2 OF 3 Frequency Adjustment: In order to guarantee that the AFC algorithm will be able to adjust the transmitter to within the specified 0.1 ppm described in EXHIBIT 3 it is necessary to measure, adjust, and store a compensating value of an un-AFCed carrier. This takes place during the manufacturing process. The mobile station transceiver is set to transmit on channel number 661 and is keyed. The frequency transmitted is measured and the offset from the desired 1880 Mhz is calculated. The voltage necessary to be applied to the reference oscillator circuit, to cause the transmitted frequency to be within 100 Khz of desired, is calculated, converted to a digital format and stored in non-volatile memory. The resolution of the tuning ability is also verified to be less than 78 Hz increments. This ensures the ability to tune to within the necessary 0.1 ppm. Transmit Output Power Adjustment: In order to guarantee that the power control circuitry will be able to adjust the transmitter to within the specified limits shown in the table of EXHIBIT 6 it is necessary to measure, adjust, and calculate calibration values to compensate for manufacturing and component tolerances in the transmitter lineup. This takes place during the manufacturing process. The mobile station transceiver is set to transmit a pseudo random data sequence on channel number 661 and is keyed. The output power is measured at both highest and lowest power steps. The voltage necessary to be applied to the power control circuitry, to cause the transmitted power to be within the limits of the table in EXHIBIT 6, is calculated. Also, the voltages required to meet specified levels of the intermediate power steps are calculated. This array of values are converted to a digital format and stored in non-volatile memory. Finally, the mobile station transceiver is set to transmit a pseudo random data sequence on channel numbers 512 and 810 and is keyed to power step 6. A further algorithm is run to calculate offset values for the values stored in non-volatile memory above to account for tolerances due to frequency variation. This ensures the ability to control the output power across the USPCS band. APPLICANT: MOTOROLA INC.FCC ID: IHDT6YH1 EXHIBIT 12 PAGE 3 OF 3 Receive I and Q Balance: With the aide of a Hewlett Packard 8922 GSM Test Set the relative levels of the demodulated quadrature baseband analog signals I and Q are adjusted to achieve a balance between the two amplitudes. With the mobile station in a call with the 8922 use the transceiver’s internal command to output the power of the I and Q signals. Store the adjusting factors into non-volatile memory to achieve a balance between the amplitudes of the two signals. Receive Audio Level Adjustment: With the aid of a Hewlett Packard 8922 GSM Test Set the receive audio level Automatic Gain Control (AGC) circuitry is adjusted to set the demodulated receive audio to calibrated levels. Once calibrated, the receive levels are then used as an indication of receive signal strength. With the mobile station in a call with the 8922 use the transceiver’s internal command to output the power of the I and Q signals. For given RF input power levels from the 8922 compensating gain control values are calculated to maintain a constant amplitude on each of these signals. This procedure is repeated over varying power input levels and over many discrete frequency bands creating a matrix of compensating factors. This matrix is stored into non-volatile memory.
