    8 channels bonded to get those figures? They are just using more bandwidth (in the radio sense) to get more bandwidth (in the bps sense)
    I think 802.11n was approaching the limits of what we can transmit over the air.

    Why?

    When 1mbit ethernet was out, it could be saturated by a then current PC transferring files. When it was updated to 10 Mbit, a current PC could saturate the link. When Fast ethernet came out, a current PC could saturate the link several times over.
    A current modern PC cannot saturate Gbit eithernet yet. 10Gbit is great for the datacentre, but not anything like needed for the home for the next 10 years at least.

    an SSD will saturate a 1Gbit link and as more people start to buy into SSD and the sizes become larger there will come a point where we will want more bandwidth.

    My server's RAID array more than saturates Gbit.

    That's why 10GbE is getting more popular in business, despite costing much more per port.

    All true, but right now and for the next few years, there just won't be the demand since most people don't have SSD's, nor will for a while yet. Even when SSD's become mainstream, over 100MByte/sec tranfsers of Gbit ethernet will be more than adequate until windows gets so bloated you need 1TB just for the install.
    I'm not saying there won't be a time when 10GbE overtakes 1GbE. Just that it will be a good 9+years until that time.
    Even now, Fast ethernet is more than adequate for most home users.

    1Gb/s? - I'll believe it when I see it. Wireless N promised 300Mb/s but it doesn't even get close. In fact, you're lucky to even get 54Mb/s, the speed promised by Wireless G.

    Also, bonding so many channels is going to cause problems in apartment and office buildings where many networks compete for the already limited bandwidth, without participating in a common contention-based protocol.

    Either they will have to develop an out of band contention-based protocol that all access points can participate in, regardless of channel, SSID and security settings, or they will have to start using thick lead walls in buildings...which would cause problems for cell phones and wireless Internet. A third option would be to open up more frequencies for unlicensed use.
