can you say HOLY THREAD RESURRECTION BATMAN.... a lot has changed since the OP in 2009
BTW LatiosXT... you're way off 72Mbps for Wireless N??? Think again... try 600Mb/sec (75MB/sec) and you didn't even claim it's per channel.... N only supports 4 channel MIMO or up to 150Mb/sec per channel
EDIT: the implication being that yes 72Mbps is a spec of Wireless N, but is not the only, or even fastest supported spec of Wireless N.
Straight from IEEE:IEEE 802.11 standards (Commonly referred to as Wi-Fi.)
802.11a: 54 Mbps, 5 GHz
802.11b: 11 Mbps, 2.4 GHz
802.11g: 54 Mbps, 2.4 GHz802.11n: 600 Mbps, 2.4 and 5 GHz
802.11ac: 1 Gbps, 5 GHz (Note: Cisco 802.11ac higher end home routers($120 & up) have 1.3Gbps bandwidth)
802.11ad: 7 Gbps, 2.4 GHz, 5 GHz, and 60 GHz
Cisco Wireless AC White Paper wrote:
802.11ac achieves its raw speed increase by pushing on three different dimensions:
• More channel bonding, increased from the maximum of 40 MHz in 802.11n, and now up to 80 or even 160 MHz (for 117% or 333% speed-ups, respectively)
• Denser modulation, now using 256 quadrature amplitude modulation (QAM), up from 802.11n's 64QAM (for a 33% speed burst at shorter, yet still usable, ranges)
• More multiple input, multiple output (MIMO). Whereas 802.11n stopped at four spatial streams, 802.11ac goes all the way to eight (for another 100% speed-up).
The design constraints and economics that kept 802.11n products at one, two, or three spatial streams haven't changed much for 802.11ac, so we can expect the same kind of product availability, with first-wave 802.11ac products built around 80 MHz and delivering up to 433 Mbps (low end), 867 Mbps (midtier), or 1300 Mbps (high end) at the physical layer. Second-generation products promise still more channel bonding and spatial streams, with plausible product configurations operating at up to 3.47 Gbps.
Just for the record, my laptop reaches 830megabits/sec bandwidth @ 5 feet from my EA-6700 Wi-Fi router
which kicks ass when transferring HD video off my file server to watch when I'm away from home! But my internet is capped at 40Mbps though I rarely see better than 20Mbps, so wasted $$$ for internet use, good investment for home LAN use.
EDIT: Just to keep with the original topic... Wi-MAX 2 was supposed to top 100Mbps by 2012... but I don't think we'll see any real-world 70+ Mbps wireless internet speeds till after 2016 when Wi-Gig (802.11ad) starts to become more commonplace & with Intel already onboard the Wi-Gig train... that's pretty much a given.
