Guys, can you help me understand this:
"How 802.11ac worksYears ago, 802.11n introduced some exciting technologies that brought massive speed boosts over 802.11b and g. 802.11ac does something similar compared with 802.11n. For example, whereas 802.11n had support for four spatial streams (4×4 MIMO) and a channel width of 40MHz, 802.11ac can utilize eight spatial streams and has channels up to 80MHz wide — which can then be combined to make 160MHz channels. Even if everything else remained the same (and it doesn’t), this means 802.11ac has 8x160MHz of spectral bandwidth to play with, vs. 4x40MHz — a huge difference that allows it to squeeze vast amounts of data across the airwaves."

I'm sorry to bother you but I'm kinda slow with this stuff. I'm trying to choose between 802.11n or 802.11ac. My first choice is the ac thing because it was recommended by a computer sales agent. However, I think it will be cheaper to get the 802.11n. Can you tell me if these two do not have any big difference in terms of speed? Thanks.
