Thread: Dual channels - how?

    Default Dual channels - how?

    I've noticed that my neighbour's wireless router comes up on inSSIDer with TWO channel bands. He's therefore occupying a huge chunk of the available spectrum . How is this possible, and is it legal?

    That would be them using an 802.11N access point in 40MHz mode. In the 2.4GHz band, this eats half of the band. This is also perfectly legal.
