RE: Emulating a wireless access point

[bparis () sorrentolactalis com]

        You are correct Meredith.

        I live near a cell tower (100m away) and can clearly hear cell
conversations on my scanner at the 1st lower harmonic, app 450-460Mhz.

        Getting back the the original question, cordless 2.4Ghz phones are
notorious for creating interference with other devices using the same freq
band. I recommend not operating 2.4Ghz phones in a wireless environment.

        Actually, it probably has to do w/ the frequency / harmonic
resonance of
the phone interfearing w/the AP ... not the proximity. Even if the phone
operates on a different frequency, it can interfere w/ the AP via harmonic
resonance.
        Harmonic Resonance occurs when one of the frequencies is a multiple
of the
other. Say your AP operates at 2 hz ( for simplicity sake) and your phone
operates at 4 hz, then every other cycle of the phones frequency will be in
phase w/ the access points.

        Are there any Ham operators out there that can confirm or deny this?
