Model: IX260 with the three co-located transmitters listed below. 1.) AIRCARD750 -supporting calculations on pages 2-4 Tx Freq: 1850.20 Tx Freq: 1880.00 Tx Freq: 1909.00 Max Peak Power @ antenna terminal input: 28.12 Max Peak Power @ antenna terminal input: 28.08 Max Peak Power @ antenna terminal input: 28.00 Antenna Gain: 0.1dBi 2.) MPI350 -supporting calculations on page 5 Tx Freq: 2450 MHz Max Peak Power @ antenna terminal input: 21.2 dBm Antenna Gain: 4.5 dBi 3.) Bluetooth -supporting calculations on page 6 Tx Freq: 2450 MHz Max Peak Power @ antenna terminal input: 14.46 dBm Antenna Gain 4.5 dBi 4.) AIRCARD750 with MaxRad External Antenna -supporting calculations on page 7 Tx Freq: 1880 MHz Max Peak Power @ antenna terminal input: 27.9 dBm Antenna Gain 3.0 dBi The MPE calculations are submitted for multiple frequency exposure criteria. The ratio of the field strength or power density to the applicable exposure limit at the exposure location was determined for each transmitter below and the sum of these ratios does not exceed the 1 mW/cm^2 limit for uncontrolled exposure / general population exposure limits detailed in CFR 47, Part 1.1310.
