    Default Wireless Networking Question

    I wonder if anyone can tell me whether spread spectrum technology like DSSS is more or less prone to interference than OFDM? I've read a couple of articles that seem to contradict each other as to which TX method penetrates walls more easily and also as to which one is more resistant to EMI.

    Thanks!

    As Far as I know DSSS is more resistant to interference as the transmission is spread over the entire epectrum, however OFDM should be harder to intercept simply because its not broadcast over the entire spectrum.
    So, are you more worried about jamming or tapping?

    Thanks - and the answer to your question is "yes!"

    I agree with you, DSSS is more resistant while OFDM is harder to intercept.

    Oh good another post by mrlocks, and as usual full of useful information

    How about you stop spamming forums and pay for advertising like a normal company.
    I will always fondly remember the days of mall security, the expressions on the thankful patrons you saved from certain molestation in the mall bathrooms. The look of pain in the drooling face of the shoplifter you just choke-holded to unconsciousness
