Measured sensitivity at 2402 MHz was found to be -86.05 dBm Peak Envelope Power (PEP). Wanted signal should, according to the Receiver Blocking Parameters Receiver Category 2 Equipment table in ETSI EN 300 328 V2.1.1, be set 6 dB above the sensitivity limits. With a measured sensitivity at -86.05 dBm that will lead to that the level on the wanted signal should be -80.09 dBm PEP (level = -102.8 dBm).

Note that there is a loss in the test setup at almost 10dB (see Section 4.1) so actual RX sensitivity level is around 96dBm.
