Gigabit wi-fi speeds soon to come?

No, they aren’t.  Well, not that soon, anyway.  Despite the fact that the IEEE organization still hasn’t published the finalized version of the 802.11n specifications, engineers aren’t standing around and twiddling their thumbs.

Prosposals are currently underway to design the next generation of the 802.11 spec — that is, the version to come after 802.11 finally launches — which is currently being tagged as 802.11 VHT.  The VHT stands for ‘Very High Throughput’ and in this case, means gigabit speeds.  It’s being designed to offer actual gigabit throughput, not necessarily just data speeds (as opposed to current wireless standards which promise anywhere from 11 to 300Mbps and rarely if ever give the maximum).

The two major proposals for the future of wi-fi come from two different angles: one offers data transmission over sub-6GHz frequencies while the other offers data transmission over 57-66GHz frequencies.  In either case, we won’t see any products based on the technologies until 2011 or 2012 at the earliest; it takes around five years for standards to be ratified.  We’ve seen the problems this causes with the current 802.11n incarnation; there have been products released based on two or three different versions of the specification, many of which are non-interoperable.  Current products only offer speeds of about half of what the final spec calls for, which is due to be published (for now) in late 2009.
