March 6 th , 2008 GSM0408 Operational Description General Description The GSM0408 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. 251 Renner Pkwy, Richardson, Texas 75080 | 972.633.4400 Tel | 972.633.4444 Fax | www.enfora.com

February 13, 2008 February 13, 2008 Tune-Up Procedure Description for GSM0408 Tune-Up Procedure Description for GSM0408 Power Adjustments Power Adjustments The RF power output of the modem is preset during the manufacturing process via software-controlled adjustment of calibration parameters referenced to a base-station simulator. 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.

Enabler ® ΙΙΙG BGA FCC MPE Calculation Revision 1.0 Confidential and Proprietary Information - © 2008 Enfora, Inc. Do not duplicate without express permission from Enfora, Inc. Enabler ® ΙΙΙE FCC MPE Calculation MPE Calculation for Enfora Enabler IIIG BGA - OET Bulletin 65 The FCC requires that the calculated MPE be equal to or less than a given limit dependent on frequency at a distance of 20 cm from a device to the body of a user. The transmitter operation for the Enabler IIIG BGA (GSM0408) radio module covers GSM850 and PCS1900 operating bands. The MPE calculation as given in FCC OET Bulletin 65, page 19 is used to calculate the safe operating distance for the user. S = EIRP/4 π R 2 Where S = Power density EIRP = Effective Isotropically Radiated Power (EIRP = P x G) P = Conducted Transmitter Power G = Antenna Gain (relative to an isotropic radiator) R = distance to the centre of radiation of the antenna Summary Conclusion The required 20cm RF exposure limits for General Population/ Uncontrolled Exposure FCC Rule Part 1.1310 will not be exceeded for the Enabler IIIG BGA using antennas having a maximum gain of 1.4dBi (850MHz) and 7.0dBi (1900MHz) respectively. Enfora, Inc. 2 OET Bulletin 65 Enabler ® ΙΙΙE FCC MPE Calculation For the Enabler IIIG BGA @ GSM850 Requirement: From table 1 (b) - Limits for General Population/ Uncontrolled Exposure of FCC Rule Part 1.1310 for GSM850 S = f/1500 mW/cm 2 (f = operating frequency) Transmitter frequency range = 824MHz to 849MHz Max. Transmitter Power = 33dBm (2.0W) @ antenna socket S = 824/1500 = 0.55 mW/cm 2 (worst case) Calculation to D etermine Maximum Antenna Gain (G) S = 0.55 mW/cm 2 P = 2000mW R = 20cm S = PxG/4 π R 2 G = S x (4 π R 2 ) / P G = 0.55 x (12.56 x 20 2 ) / 2000 G = 1.38 (1.40dBi) For the Enabler IIIG BGA @ GSM1900 Requirement: From table 1 (b) - Limits for General Population/ Uncontrolled Exposure of FCC Rule Part 1.1310 for PCS1900 S = f/1500 mW/cm 2 (f = operating frequency) Transmitter frequency range = 1850MHz to 1910MHz Max. Transmitter Power = 30dBm (1.0W) @ antenna socket S = 1.0 mW/cm 2 (worst case) Calculation to determine maximum Antenns Gain (G) S = 1.0 mW/cm 2 P = 1000mW R = 20cm S = P x G / (4 π R 2 ) G = S x (4 π R 2 ) / P G = 1 x (12.56 x 20 2 )/ 1000 G = 5.02 (7.0dBi) Enfora, Inc. 3 OET Bulletin 65
