Radio Receiver Sensitivity

Receiver sensitivity is the lowest power level at which the receiver can detect a Radio Frequency (RF) signal and produce a specified output signal. The ability of a device to pick up strong transmit signal and a high receiver sensitivity performs better in low WLAN coverage than a device with weaker signals.

The following table shows the radio receiver sensitivity for Vocera devices at 2.4 GHz data rates.
