1. A method, comprising:

  • scanning, by a communication device, a radio frequency spectrum of a communication network;

    identifying, by the communication device, an available frequency band in the radio frequency spectrum for initiating a communication session having a transmission link and a reception link for exchanging data with a remote wireless device operating within the available frequency band;

    selecting, by the communication device, the available frequency band for engaging in communications independent of a presence of interference in the available frequency band;

    determining, by the communication device, a correlation factor by correlating a signal strength in portions of the available frequency band;

    detecting, by the communication device, according to the correlation factor an interference signal in the available frequency band;

    responsive to determining the interference signal adversely affects the reception link;

    generating, by the communication device, tuning coefficient data to suppress at least in part the interference signal; and

    filtering, by the communication device, a first signal from the wireless device and in the reception link of the available frequency band according to the tuning coefficient data to generate a filtered signal; and

    responsive to determining the interference signal adversely affects the transmission link;

    generating a second signal for transmission to the wireless device and in the transmission link of the available frequency band adapted to circumvent at least in part the interference signal detected in the available frequency band; and

    transmitting the second signal in the available frequency band.
