:No, it probably has more to do with the fact that they both operate in the
:unlicensed but regulated 2.4Ghz band.

        That's not incompatible w/ my earlier surmise...as long as two frequencies
aren't relatively prime, they can cause harmonic interfearence w/ each
other. There are many frequency pairs in the 2.4 Ghz range that meet this
criteria.
        FCC Regulation has nothing to do w/ the laws of physics. The fact that two
devices operate in an unregulated range do not cause them to interfere with
each other. I doubt the underlying electronics of the device are even aware
of FCC regulation.

:I strongly disagree with your methodologies. Please explain?

        I wasn't proposing a methodolgy, just one possible explanation of the cause
of an event. Possible -- I'm not an RF expert by far.

      Actually, it probably has to do w/ the frequency / harmonic resonance
of the phone interfearing w/the AP ... not the proximity.

No, it probably has more to do with the fact that they both operate in the
unlicensed but regulated 2.4Ghz band.

You _may_ get some relief by manipulating the channel on the access point or
on the telephone handset.
