It is no secret that 802.11n is hot. The release of two recent tests comparing systems based on Draft 802.11n chip sets elicited a lot of interest from readers over the past two weeks.
On August 8, I blogged about tests conducted by The Tolly Group and sponsored by Metalink. See 802.11n face off favors Metalink.
Last week, we published a three-part series based on another independent test conducted by octoScope. It was sponsored by three companiesD-Link, Atheros and Ubicom. See Not all "n" is created equal.
Since the octoScope test had three corporate sponsors instead of just one there is a tendency to place more value on its results. Moreover, the two tests are not an apples-to-apples situation. Different systems were tested and different test environments were used.
Nevertheless, the results seem to line up reasonably well given those differences. They certainly support the contention that videoespecially HD videoover an 802.11n link is easy to accomplish.
We'll be following this story carefully though the next holiday buying season so stay tuned for more developments.
