A 12-Gb/s -16.8-dBm OMA Sensitivity 23-mW Optical Receiver in 65-nm The receiver sensitivity = What you need to have leftover at the end of the month for food. IEEE 802.15.4 requires only 85 dBm of sensitivity for operations in the 2.4 GHz ISM band. Since -78 dBm is lower than -69 dBm, that means option 1 has a more sensitive receiver. The link margin must be positive (Received Power > Receiver sensitivity) and should be at least a few dB for the receiver to successfully demodulate the signal. In the 868/915 MHz band, if the BPSK modulation is used, the required sensitivity is 92 dBm.
