    I'll go with B, read a quick article that mentioned microwaves could interfere, but whether they interfere that much i couldnt tell u !

    :roll:

    Time's up. Correct answer is B. Older microwaves can leak as much as a watt of RF energy. A watt isn't much relative to a microwave oven but it's a huge amount of energy compared to what an AP is allowed to emit.

    Bluetooth is a real trouble maker in terms of narrowband interference and all-band interference can run the entire RF spectrum...not just the 2.4GHz band. The best solution for this problem (if possible) is to change technologies. The next best is to remove the source of the interference.

    More tomorrow.

    I watched a program the other day, in which a hacker easily gained access to a bluetooth enabled mobile phone.

    Apparently, bluetooth are working on a patch, but in the meantime, an expert said don't use bluetooth in your mobile if you want your details to remain private.

    They were talking mobiles, but I'm not sure if this concerns all devices with bluetooth.

    Anyway, ti was interesting to watch this.

    Thanks :!:
