Interoperability now guaranteed as high-speed wireless loses 'draft' status

The high-speed wi-fi format 802.11n has finally become an official standard, losing its 'draft' status and guaranteeing that 802.11n devices will work together. That ends a long period of uncertainty during which huge numbers of products have been sold with '802.11n draft' status.

802.11n has been around for many years, having first been mooted as far back as 2002, and it's been part of computers, routers and other devices for a long time. But it's only now that the Institute of Electrical and Electronics Engineers Standards Association has ratified it as a finished standard at the end of last week.

It did so in the form of a 560-page amendment to the IEEE802.11 standard, but to save you all the reading suffice it to say that all products sold to date as '802.11n draft' will work with it.

IEEE802.11n allows for data transfer at up to 300Mbps, instead of 802.11g's 54Mbps, and over indoor distances of up to 90m, twice the range of 802.11g.
