A frequency translating repeater ( 200 ) for use in a WLAN environment includes an in-band management link. A signal received on an antenna ( 300 ) is split to provide signal detection in a detection and control unit ( 385 ) wherein detection is performed by detectors ( 370, 371 ) filters ( 375, 376 ), converters ( 380, 381 ) and a processor ( 385 ). Delay is added using delay lines ( 360, 361 ). The in-band signal envelope may be modulated with variable gain amplifier ( 330 ) and demodulated with detectors ( 370, 371 ) to establish the management link with higher protocol layer capability. Alternatively, a modern function at least partially compliant to 802.11 modulation may be used in parallel with the frequency translating repeater.
