802.11n Wi-Fi imperiled by patent problems?

When last we visited the upcoming 802.11n standard for Wi-Fi, the IEEE was working slowly on the official standard while manufacturers were rushing out and certifying Draft 2 compatible products. Now The Register reports that there’s a spanner in the gears since some outstanding patents actually threaten the IEEE adoptability of the 802.11n standard.

First 802.11n Draft 2.0 products certified

As I mentioned in May, the program for “Wi-Fi CERTIFIED 802.11n Draft 2.0″ products was to get started in June, and last Friday it bore first fruit as the first router and adapter were certified:

802.11n Draft 2 logo program due in June

Even though the 802.11n specification appears to be 2 years from ratification, the Wi-Fi Alliance today announced they are starting a logo program for “pre-n” Wi-Fi networking gear:

Wi-Fi CERTIFIED 802.11n draft 2.0 products sporting an eye-catching new logo will soon reach store shelves, as the Wi-Fi Alliance certification program nears its late June launch. The Alliance today unveiled a re-designed consumer logo for Wi-Fi CERTIFIED 802.11n Draft 2.0 products, and announced the products and reference designs that will comprise its test bed for interoperability certification.

The practicalities of the matter are that while there is a lot of bureaucratic jockeying going on over the details of the final 802.11 n spec, Draft 2.0 is close enough that presumably all logo certified gear will be upgradeable to the final standard with just a firmware upgrade.

Since there are no Draft 2.0 products shipping yet, a natural question is whether any pre-n products currently available will be upgradeable to Draft 2? The answer is “that depends” and to check with the manufacturer, although there is a good chance that any Draft 1 pre-n gear will be firmware upgradeable. The vendors should be very upfront since this kind of thing kills sales dead until the information is forthcoming.

On the other hand, if you prefer to avoid the excitement of a firmware upgrade, hold off on any new Wi-Fi gear until June and look for the following logo for the certified 802.11n Draft 2.0 products:
