RF Exposure Evaluation (MPE) Per IC requirements, SARS testing is not required when maximum average power ≤ 60/fGHz mW. For 915MHz, the maximum average power will have to be under 65.57mWatts. The MVR900 has an average power well under the above limit with an on/off time ratio of < 1/8. 8 X 65.57mWatts = 524milliwatts which is greater than 27dBm. All peak power measurements were under the 27dBm limit.
