3.3.2 Assumptions 1. Primary transmitter does not support power reduction for multiple time slots on the uplink. 2. Antenna separation from module to human body is ≥ 20cm. 3. Separation distance between co-located transmitting antennas is 0cm. 4. Hypothetical Bluetooth radio is assumed to have an output power of 9.5dBm and an antenna gain of 4dBi. 5. Hypothetical WLAN radio is assumed to have an output power of 19dBm and an antenna gain of 5dBi. 6. Where the maximum allowable gain permitted with respect to EIRP is lower than the maximum allowable gain for relative exposure, the lower gain respecting the EIRP limit shall be used to make the calculation. 3.3.3 Test Protocol The below table is to determine the MPE values using the maximum gain values obtained in below.
