RSSI in FSK/OOK Mode The RSSI provides a measure of the incoming signal power at RF input port, measured within the receiver bandwidth. The signal power is available in RssiValue. This value is absolute in units of dBm and with a resolution of 0.5 dB. The formula below relates the register value to the absolute input signal level at the RF input port: RssiValue = −2⋅ RF level[dBm]+ RssiOffset [dB] The RSSI value can be compensated to take into account the loss in the matching network or even the gain of an additional LNA by using RssiOffset. The offset can be chosen in 1 dB steps from -16 to +15 dB. When compensation is applied, the effective signal strength is read as follows: RSSI [dBm] = − RssiValue 2 The RSSI value is smoothed on a user defined number of measured RSSI samples. The precision of the RSSI value is related to the number of RSSI samples used. RssiSmoothing selects the number of RSSI samples from a minimum of 2 samples up to 256 samples in increments of power of 2. Table 83 gives the estimation of the RSSI accuracy for a 10 dB SNR and response time versus the number of RSSI samples programmed in RssiSmoothing. |
