Applicant: Itronix, Corporation FCC ID: KBCIX600-MC75 & KBCIX600-BT MPE Estimates for Co-Located Device FCC ID: KBCIX600-MC75 GSM/GPRS Ratio of General Max Peak Minimum Power Power Population Transmit Conducted Antenna Antenna Density Antenna Type Antenna Part No. Density Exposure Frequency Output Gain Cable to the @ 20 cm Limit from Power Loss Exposure 1.1310 Limit (MHz) (mW) (dBi) (dB) (mW/cm2) (mW/cm2) Internal Skycross WAN 59-0479-001 1880 724.4 -0.3 1.76 0.095 1 0.095 Internal Skycross WAN 59-0479-001 836 1410 3.8 0.89 0.548 0.55 0.984 External MaxRad BMLPVDB800/1900 1880 724.4 3 4.61 0.099 1 0.099 External MaxRad BMLPVDB800/1900 836 1410 3 2.45 0.318 0.55 0.571 Worst Case Ratio of Power Density to the Exposure Limit = 0.984 - duty cycle not considered = 0.492 - duty cycle of 50% applied If source based time averaging is considered, the power density at 20 cm can be further reduced [per 2.1091(d)(2)]. The EUT is a GSM radio so the time-averaged power density is actually 4/8 the value of the un-modulated carrier. With source-based time averageing applied the ratio of power density to the exposure limit is 0.492. Excerpts from TCB Training, April 3, 2002, “Mobile Transmitters”, Slide 6: “Devices operating in multiple frequency bands ‰ When RF exposure evaluation is required for TCB approval o Separate antennas – estimated minimum separation distances may be considered for the frequency bands that do not require evaluation or TCB approval, however, the estimated distance should take into account the effect of co-located transmitters. (Note 24) Note 24 According to multiple frequency exposure criteria, the ratio of field strength or power density to the applicable exposure limit at the exposure location should be determined for each transmitter and the sum of these ratios must not exceed 1.0 for the location to be compliant.” The sum of the ratio(s) (power density to the exposure limit) does not exceed 1.0; therefore, the exposure condition is compliant with FCC rules. 2
