1. A method for continuous 5 GHz and 6 GHz operation by a network device, comprising:
receiving, by the network device, a first signal in a 5 GHz band;
generating, by the network device, a second signal in a 6 GHz band;
selecting, by the network device, a first filter or a second filter to be applied the first signal in the 5 GHz band, wherein the first filter allows a lower frequency band to pass than the second filter in the 5 GHz band;
selecting, by the network device, a third filter or a fourth filter to be applied to the second signal in the 6 GHz band, wherein the third filter allows a lower frequency band to pass than the fourth filter in the 6 GHz band, and wherein the third filter achieves at least a 50 dB rejection in a transition gap of 200 MHz; and
simultaneously applying, by the network device, the selected first or second filter to the first signal and the selected third or fourth filter to the second signal.
