Please either confirm that the transmitters operate standalone or, if the transmitters can transmit simultaneously, include the necessary calculations for simultaneous transmission per ISED RSS-102 issue 5 section 3.1.2. The device has two radios on board, a Z-wave and BLE. The radio can occasionally simultaneously broadcast however the fundamental signals are on different frequencies, 900 MHz ISM band and 2.4 GHz ISM band. The radios do not share a common antenna. Each radio has its own antenna. The BLE is pre-certified module bearing its own FCC and IC identification numbers and is being used with approved antennas. Calculations for simultaneous transmission per KDB 447498 D01 v06 section 7.2 is provided here to show that Simultaneous transmission MPE test exclusion applies since the sum of the MPE ratios for all simultaneously transmitting antennas incorporated in a host device is ≤ 1.0. Per ISED RSS-102 (I5) section 3.1.2 other recognized methods can be used to show compliance; therefore, this method is used to show compliance to RSS-102. Total Sum of MPE: Sum of the total MPE for both frequency bands = 0.0002/1 mW/cm 2 + 0.005944/1 mW/cm 2 = 0.006 which is << less than 1.0 The EUT was tested with all radios ON and active during collocation testing. The emissions generated with a single radio ON and active versus all radios ON and active did not produce additional unwanted spurious emissions or intermodulation that would require additional testing. The radios can be collocated as designed.
