802.11n puts the why into WiFi

Belkin has announced the launch of their N1 range of next generation wireless routers based upon a new WiFi standard that could extend the range of existing ‘wireless-G’ solutions by a factor of 4, and speeds by as much as 12. This might bring out the excited little geek in me, were it not for the fact that there isn’t any standard yet, no guarantee it will work properly with other 802.11n kit (even from the same manufacturer) now or in the future, and most damning of all: nobody really needs it.

 

OK, so when has need ever stopped an early adopter? Good point, but even the usual desire to own the latest technology is dampened by the realisation that you’re getting absolutely no practical benefit whilst still paying over the odds for the privilege of testing the product line. Being an early adopter you’ll no doubt already have invested in Multiple Input,

Multiple Output (MIMO) enabled kit if you really required the extended range on offer. The test reports I’ve read so far would suggest that MIMO, which is also a key part of the emerging 802.11n specification, is just as effective on existing 802.11g devices anyway. Which just leaves the speed issue, and let’s face it that’s the real hard sell for Wireless-N isn’t it? The marketing blurb makes for moist reading: up to 600Mbps throughput claim some vendors. But a claim is all it will remain for some time to come, as a closer inspection of the facts reveals.
