February 13, 2008 February 13, 2008 EDG0308 Circuit Description EDG0308 Circuit Description General Description General Description The EDG0308 Module utilizes the Texas Instruments Neptune baseband processor integrated circuit, TI Triton power management / analog integrated circuit, and Renesas RF transceiver, PA, and Front End Module (FEM). Radio Interface The Renesas transceiver, PA, and Front-End-Module (FEM) comprise the complete RF front-end for the GSM/GPRS/ EDGE functions. The FEM contains the TX/RX RF switch, and the RF RX band-select SAW filters. The transceiver contains the up-conversion circuits (for TX), down-conversion circuits (for RX), and PA and FEM control circuitry. The transceiver uses a digitally controlled crystal (26 MHz) oscillator (DCXO) that integrates the reference oscillator and varactor functionality. The PA contains a high band (1800/1900 MHz) and low band (850/900 MHz) PA’s, and automatic power control (APC) feedback elements. Baseband Interface The Neptune baseband processor provides all digital interfaces and control of the system. The Triton 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 EDG0308 Tune-Up Procedure Description for EDG0308 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 ® ΙΙΙE FCC MPE Calculation Revision 1.0 Confidential and Proprietary Information - © 2007 Enfora, Inc. Do not duplicate without express permission from Enfora, Inc. Enabler ® ΙΙΙE FCC MPE Calculation MPE Calculation for Enfora Enabler IIIE - 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 IIIE 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 IIIE 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 IIIE @ 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 IIIE @ 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
