Selective filtering to reduce interferences in Wi-Fi communications

A method comprising:

• operating a first radio and a second radio of a wireless networking device on a first channel within a first sub-band and a second sub-band of a first frequency band, wherein the first and second radios are dedicated to operating over the first sub-band and the second sub-band, respectively;
• operating a third radio and a fourth radio of the wireless networking device on a second channel within a third sub-band and a fourth sub-band of a second frequency band, wherein the first sub-band and one of the third or fourth sub-band are immediately adjacent to an inter-band gap separating the first frequency band and the second frequency band, and wherein the third and fourth radios are dedicated to operating over the third sub-band and the fourth sub-band, respectively;
• operating a fifth radio of the wireless networking device on a third channel within a third sub-band of the first frequency band;
• selecting one of a first filter or a second filter based on the first channel, wherein a collective passband of the first filter and the second filter is equivalent to the first sub-band;
• selecting one of a third filter or a fourth filter based on the second channel, wherein a collective passband of the third filter and the fourth filter is equivalent to one of the third or fourth sub-band;
• communicating a first signal over the first channel through a selected one of the first filter or the second filter;
• communicating a second signal over the second channel through a selected one of the third filter or the fourth filter to avoid communication interference between the first channel and the second channel;
• and
• communicating a third signal over the third channel through a fifth filter to avoid communication interference among the first channel, the second channel, and the third channel.
