Will “N” Rescue MuniFi?
Posted by samc on August 22nd, 2007
There are now some 71 products that offer some 802.11n compatibility. This January, the 802.11n working group okayed Draft 2.0 with the full IEEE approving it some months later. The next step is Draft 3.0, which should see only minor modifications from 2.0, followed by the official 802.11n specification late next year.
Draft 2.0 hardware is guaranteed to work with the final 802.11n specification. That means any upgrade can probably be made with a firmware download.
A new 802.11n home router may be worth the price premium just for the improved range around the house. If an “N” client with MIMO can link to an ordinary WiFi access point at nearly twice the range, as one might hope (with MIMO antennas built into laptops), perhaps municipal WiFi might actually prove useful.
The issue of 40 MHz channels in the 2.4 MHz band remains a concern, says Wireless Design Line, with the protocol for interference avoidance still unsettled in the 802.11n draft. All 801.11n draft 2.0 certified products are listed at Wi-Fi.org.

That was a useful headsup. Thank you.
