Level PEP Ok Pkt PER[%]
-105.0 -82.29 148 1.33 %
-106.0 -83.29 141 6.00 %
-107.0 -84.29 132 12.00 %
-108.0 -85.29 117 22.00 %
-108.6 -85.89 104 30.67 %
-109.0 -86.29 94 37.33 %
-110.0 -87.29 45 70.00 %

Measured sensitivity at 2480 MHz was found to be -85.89 dBm PEP. The 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 of -85.89 dBm this leads to that the level on the wanted signal being -79.89 dBm PEP (level = -102.2 dBm).

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