CETECOM Inc. 411 Dixon Landing Road Milpitas, CA 95035 Federal Communication Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Attention: Reviewing Engineer The Itronix Laptop is a ruggedized Laptop with a built in GSM/GPRS card. Due to the construction and the position of the antenna (TX and RX) a minimum distance under normal operating conditions of more than 20 cm to the antenna is guaranteed. The manual contains a relevant statement. The calculation was made for this worst case. The maximum peak output power for this device is 581 mW (27.64 dBm). Regarding MPE limits, GPUC environment limits maximum exposure to 1 mW/cm2. The power density is: S = E2/3770=-13 H2 < 1 mW/cm2 Where: S = Power density (mW/cm2) E = electrical field strength (V/m) This formula converted using the EIRP is Pout *G/4π*r2 (mW/cm2) 581/4π*202 = 0.1156 mW/cm2 Calculations are based on standard formula for calculating field strength at a distance and converting power density using free space impedance. Further this device uses the GSM protocol, which is a TDD format ratio of 1/8 in GSM mode and in 4/8 in GPRS mode. This reduces the max. power density to 0.0578 mW/cm2 . If you should have any questions regarding this submission, please feel free to contact the undersigned. Yours truly, Lothar Schmidt Technical Manager EMC/Radio CETECOM Inc.
