American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 February 6, 2007 RE: FCC ID: MIVGSM0308_ATCB004517 Attention: Tom Tidwell I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. Please note that the FCC states that the actual frequencies used ar to be on the grant. This means that for this application the following frequencies are to be on the grant: 824.2-848.8MHz and 1850.2-1909.8MHz. Please correct the 731 to reflect the actual frequencies for this application. 2. Please explain if this is a licensed modular transmitter application. 3. Please explain how the label is permanently attached to the device. 4. Please note that it appears that the manual uses 7watts for the part 22 MPE information. Please note that this is not correct. Please note the highest gain antenna usable for this device under part 22 MPE at 824.2MHz to keep the 20cm separation would be 2.1dBi (32.3+2.1=34.4dBm or about 2.75W. For the part 24 MPE the highest gain antenna usable would be about 5.8dB. However, as noted in the manual, the limiting factor at 1999MHz PCS is the 2W eiro allowed for mobile devices. This means that the highest gain antenna usable for the part 24 configuration would be less than that of the part 22 configuration or about 1.84dBi. Please correct the manual to reflect the actual maximum antenna gains for this device. 5. Please correct your MPE reports to reflect the actual measured antenna conducted power form the report. For part 22, as the highest power was measured at the 824MHz end and since this is the lower MPE rating this would be a power of 32.3dBm and an antenna gain of 2.1 and for part 24 this would be a power of 31.17 and a max antenna gain of 1.84dB. 6. Please note that the part 22 radiated spurious emissions data appears to be in EIRP and not ERP as required by the rules. Please correct the data to show ERP values for part 22. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application.

Please note that further comments may arise in response to answers provided to the questions below. 1. Please note that the FCC states that the actual frequencies used ar to be on the grant. This means that for this application the following frequencies are to be on the grant: 824.2-848.8MHz and 1850.2-1909.8MHz. Please correct the 731 to reflect the actual frequencies for this application. It was my understanding that this is the case only with unlicensed devices. I have updated the Form 731 in any case. 2. Please explain if this is a licensed modular transmitter application. My understanding was that FCC does not really provide for licensed modular approval. This device is sold for integration into various end products however. The purpose of the integration guide is to warn the integrator that the device can only be used in fixed and mobile rf exposure configurations and that a new approval must be obtained if the device is to be used in a Portable configuration. It looks like for previous certifications ITS did for these guys they put a note about the module but did not include “modular” in the description note. See the attached grant for a previous version of this device. 3. Please explain how the label is permanently attached to the device. The label is silk screened onto the PWB. 4. Please note that it appears that the manual uses 7watts for the part 22 MPE information. Please note that this is not correct. Please note the highest gain antenna usable for this device under part 22 MPE at 824.2MHz to keep the 20cm separation would be 2.1dBi (32.3+2.1=34.4dBm) or about 2.75W. For the part 24 MPE the highest gain antenna usable would be about 5.8dB. However, as noted in the manual, the limiting factor at 1999MHz PCS is the 2W eirp allowed for mobile devices. This means that the highest gain antenna usable for the part 24 configuration would be less than that of the part 22 configuration or about 1.84dBi. Please correct the manual to reflect the actual maximum antenna gains for this device. I agree that the 7 watts should be changed in the user manual. However, for the MPE prediction I believe it would be appropriate to use a duty cycle 0f 50% rather than 100% since the GSM technology has a source-based time duty cycle. In most cases the time slice for a GSM signal would be such that the duty cycle would be less than 50%. In this case the maximum gain for MPE compliance would be 4.5 dBi for GSM850 (to comply with MPE at 20 cm) and 2 dBi for GSM1900 (to comply with the maximum 2 watts eirp). Please see the revised MPE data sheets. For a fixed installation (antenna mounted on a permanent outdoor structure as per integration guide) with 2 meters minimum separation, a higher gain antenna could be used. 5. Please correct your MPE reports to reflect the actual measured antenna conducted power form the report. For part 22, as the highest power was measured at the 824MHz end and since this is the lower MPE rating this would be a power of 32.3dBm and an antenna gain of 2.1 and for part 24 this would be a power of 31.17 and a max antenna gain of 1.84dB. Please see above notes concerning duty cycle. 6. Please note that the part 22 radiated spurious emissions data appears to be in EIRP and not ERP as required by the rules. Please correct the data to show ERP values for part 22. See the revised FCC report with erp fs of spurious data .

GSM0308 Circuit Description Enfora, Inc. 661 E. 18 th Street Plano, TX 75074-5601 (972) 633-4400 Fax (972) 633-4444 January 29, 2007 GSM0308 Circuit Description General Description The GSM0308 Module utilizes the Texas Instruments Locosto digital signal processor/digital radio processor (DSP/DRP) integrated circuit. This DSP/DRP is highly integrated and provides all modem functions when combined with the TI Triton Lite analog and power management IC. RF amplification and routing is accomplished with a combined RF power amplifier/switch module. Radio Interface The Locosto DRP and RF amplifier/switch provide the complete RF front-end for the GSM/GPRS functions. The receiver section encompasses the RF switch, RF band-select SAW filters and the DRP. The DRP is directly integrated to the DSP on the same IC. All down conversion and signal processing is done directly within the DRP. The transmit section consists of a direct connection from DRP through the power amplifier/switch module to the RF connector port. All carrier generation and modulation is performed within the DRP. The DSP/DRP uses a digitally controlled crystal (26 MHz) oscillator (DCXO) that integrates the reference oscillator and varactor functionality. Baseband Interface The Locosto DSP provides all digital interfaces and control of the system. The Triton Lite analog and power management chip controls all power domains and analog interfaces. It utilizes input from a 32KHz crystal oscillator to provide real-time clock and synchronization for external interfaces. Triton also performs digital to analog translation and amplification for all audio interfaces.

Under normal operation, the RF output power is maintained via an ALC circuit. Neither the integrator nor end-user has access to the calibration/power adjustment of the device. Frequency Adjustments Under normal operation, the transmitter uses a frequency synthesizer synchronized to a base- station clock, thus there are no frequency alignments that must be made.

Prediction of Maximum Permissible Exposure Equation from page 18 of OET Bulletin 65, Edition 97-01 where: S = power density P = power input to the antenna G = directional power gain of the antenna relative to an isotropic radiator R = distance to the center of radiation of the antenna *RF output power at antenna terminal(dBm):29.30 *RF output power at antenna terminal(W):0.851 Antenna gain for prediction(dBi):4.52.35 dBd Maximum antenna gain(numeric):2.8183829 Prediction distance(cm):20 Prediction frequency(MHz):849 Limit for uncontrolled exposure(mw/cm²): 0.533 S(mw/cm²) = :0.477 *A 50% duty cycle is used for this prediction based on the allowance in the Rules for source-based time averaging of the rf exposure levels. 50% was chosen as a conservative estimate of the dwell time of a GSM mobile carrier. A GSM TDMA frame is 4.615 msec. with eight 0.577 msec. transmit bursts during the frame length. One physical channel is one out of the eight bursts. The maximum number of bursts the mobile might transmit is two (1.154 msec. in each 4.615 msec. frame), or 25% of the time. Allowing for timing tolerances and other factors it is reasonable to use a 50% duty cycle factor for the rf exposure prediction. Thus 3 dB was subtracted from the measured peak power of 32.3 dBm for the purposes of this prediction. 2 4 PG S RΠ =
