 SmallNetBuilder – Small Network Help – 802.11n Headed for September Ratification

Cited text from SmallNetBuilder article

SmallNetBuilder has learned from a reliable source that the final issues in 802.11n have been resolved in this week’s meeting of the IEEE TGn in Montreal.

The draft standard is now expected to successfully pass through the final steps required for a ratification as a final standard in September. This is four months earlier than the currently published January 2010 date.

The key issue holding up the standard has been the mechanisms to be used to prevent interference between 802.11n and Bluetooth devices.

My Comments on this stage for 802.11n

Once this standard is ratified, most of us can now buy 802.11n-compliant wireless-network hardware while being sure it will work with other manufacturers’ equipment.

But the main issue with this ratification is whether most hardware manufacturers will roll out firmware for existing draft-specification 802.11n hardware that is in the field. This is of importance whenever newer final-specification hardware is deployed, because there could be compatibility issues between the different versions of the standard.

A good step to go about this is to go to manufacturers’ Websites and look for upgrade packages for any 802.11n hardware. In the case of laptops, use the laptop manufacturer’s Website or “quick-update” routine to check for updates for the wireless-network subsystem. If you run an “n-box” or other equipment serviced by your Internet service provider, check with the provider if there is new firmware in the pipeline for the hardware. This may be dependent on whether the device’s manufacturer is rolling out compatible firmware for provider-distributed devices.

In some cases, you may need to run your 802.11n wireless network segment on a “mixed” setup which observes best compatibility with 802.11g devices even if the segment is running only with “n” devices.
