The potential for interference is probably nil for Channel 1 BUT if you choose channel 10 your 802.11 would probably be toast. Microwave oven is near channel 10 dudes about 20 MHz wide, sloppy spectrum and is CW!!

This is also true of the phones. They have 4 or 5 channels. Instructions are usually to choose the quietest phone channel based on hearing it. Well, if used with 802.11 the channel with the most noise is nearest the 802.11.

802.11 is usually defaulted by the software guys to channel 1. This is away from the microwave but closer to the phones. At least the phones that I've seen.
