What is Super G Technology?

[PleaseHelp]

I was at the best buy store here in chicago and i overheard one of the reps talking about Super "G" Technology and it can make things faster, before i got a chance to ask him was it he took off with a customer and my wife pulled me out of the store, ,so i didnt get a chance to find out. I am assuming is something fairly new since i have not seen that about about it.

I have heard of many types of routers and switches, but have never heard, Super G Technology, what is that? Does it expand the size of the coverage. does it speed up downloads or uploades from the internet? is it for laptops? what is it? Thank you.

Alright, here are some comments and reviews that i found on the "The Super G" I personally have learned that Super G has it peaks and needs some tweaks, but its a great piece of hardware if you can use it.

Atheros Super G technology operates in two modes to increase bandwidth. The base mode uses standards-based data compression, large frames and bursting features to deliver real-world network throughput in excess of 40 Mbps for typical data files, an increase of up to two times over traditional 802.11g networks. The new Dynamic Turbo extends the feature set of Super G products by adding a capability that automatically detects and adapts to nearby Super G, 802.11g, and 802.11b products.

Super G products employ a number of technologies to achieve performance gains over standard 802.11g products. The primary (and most problematic from a standards standpoint) is channel bonding. Super G products can bond two 20-MHz channels together. This 40-MHz footprint is centered on channel 6. This can cause adjacent channel interference on the only other two nonoverlapping channels in the 2.4-GHz spectrum, channels 1 and 11. That means the introduction of a Super G access point in close proximity to an existing 802.11g network can dramatically decrease the performance of the 802.11g network.

Another technology used by Super G is packet bursting, which lets the AP and client card send more packets on each transmission, thereby making better use of air time by reducing the number of interpacket intervals. In addition, Super G's fast packets technology packs more data into each packet.
