Abstract
The present invention provides a modem (100), method (300) and device (103) for indicating received signal strength and presence for intensity modulated binary-coded data packets with reduced recovery time in a packet data receiving system. The device includes a receiver for binary coded wireless data packets having a first band-pass processing unit, for receiving modulated electromagnetic signals and converting the modulated electromagnetic signals to binary data signals and a second band-pass processing unit, coupled to the receiver, for providing a logarithmic received signal strength indicator signal, RSSI, using a low-frequency cutoff f.sub.L2 greater than a low-frequency cutoff f.sub.L1 of the first band-pass processing unit.
