A method of managing a communication between devices (10, 12, 14, 16) in a network, the method being performed by a network device and comprising: analyzing spectral use to determine available frequency spectra; continuously receiving signals transmitted in a band of frequencies; and transmitting a beacon signal at a beacon frequency within the band of frequencies while receiving the signals transmitted in the band of frequencies; wherein continuously receiving signals transmitted in the band of frequencies and transmitting the beacon signal over the beacon frequency within the band of frequencies while receiving in the band of frequencies is enabled by implementing a division-free duplexing, DFD, technique in the network device (14, 16); said method characterised in that the DFD technique comprises: receiving an analog primary signal from a receiver front end, an antenna, or a receiver input port; receiving an analog reference signal from a transmitter; converting the analog primary signal into a digital primary signal; converting the analog reference signal into a digital reference signal; processing the digital reference signal with a digital adaptive filter, wherein the digital adaptive filter uses the digital reference signal and digital primary signal as inputs for determining filter weights of the digital adaptive filter to provide an output; and subtracting the output of the digital adaptive filter from the digital primary signal to generate a digital cancelled signal. analyzing spectral use to determine available frequency spectra; continuously receiving signals transmitted in a band of frequencies; and transmitting a beacon signal at a beacon frequency within the band of frequencies while receiving the signals transmitted in the band of frequencies; wherein continuously receiving signals transmitted in the band of frequencies and transmitting the beacon signal over the beacon frequency within the band of frequencies while receiving in the band of frequencies is enabled by implementing a division-free duplexing, DFD, technique in the network device (14, 16); said method characterised in that the DFD technique comprises: receiving an analog primary signal from a receiver front end, an antenna, or a receiver input port; receiving an analog reference signal from a transmitter; converting the analog primary signal into a digital primary signal; converting the analog reference signal into a digital reference signal; processing the digital reference signal with a digital adaptive filter, wherein the digital adaptive filter uses the digital reference signal and digital primary signal as inputs for determining filter weights of the digital adaptive filter to provide an output; and subtracting the output of the digital adaptive filter from the digital primary signal to generate a digital cancelled signal. receiving an analog primary signal from a receiver front end, an antenna, or a receiver input port; receiving an analog reference signal from a transmitter; converting the analog primary signal into a digital primary signal; converting the analog reference signal into a digital reference signal; processing the digital reference signal with a digital adaptive filter, wherein the digital adaptive filter uses the digital reference signal and digital primary signal as inputs for determining filter weights of the digital adaptive filter to provide an output; and subtracting the output of the digital adaptive filter from the digital primary signal to generate a digital cancelled signal.
