Great answer John!
But without wishing to sound dull and mundane here's my personal techie view. WiFi networks run in the 2.4 GHz and 5 GHz range. Any interference from an AC source will be in the 50 (or 60) Hz range. From my old radio days I think you also need to consider further intermodulation products of the source interference i.e. 100(120), 150(180), 200(240), 250(300) etc Hz. As I recall each subsequent intermod product is 3 dB lower (or half the power of) than the previous product and so very quickly higher order products become effectively background noise. Therefore if the source is a very low frequency I doubt very much whether it would have any interference impact on WiFi operating in the GHz range.
What might have an impact is HV electrical switching equipment which is capable of producing high frequency noise during a switching cycle, but again it's probably not a big deal and I think the WiFi unit would need to be very close to the source, which might give you the same result as John described :-)
Now if there's someone out there with a good RF background who can corect me I'll be happy to learn from you.
All the best,
Dave.Private Reply to Dave Porteous (new win) |
