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 Prophet 4000 device is a Wireless Remote Tank Monitor with a built in GSM card – Q24 EXT from Wavecom. Due to the construction and the position of the antenna, the distance under normal operating conditions of more than 20 cm is guaranteed. The maximum output EIRP power for 850 MHz band: 601.11 mW (27.79 dBm) @ 824.6 MHz. The maximum output EIRP power for 1900 MHz band: 1 629 mW (32.12 dBm) @ 1850.2 MHz. Regarding MPE limits, GPUC environment limits maximum exposure to 1 mW/cm2. The power density is: S = E2/3770=-13 H2 = limit < 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 601.11/4π*400 = 0.120 mW/cm2 1 629/4π*400 = 0.324 mW/cm2 Calculations are based on standard formula for calculating field strength at a distance and converting power density using free space impedance. If you should have any questions regarding this submission, please feel free to contact the undersigned. Yours truly, Val Tankov Project Engineer CETECOM Inc.
