While 802.11n DOES provide reduced interference between the client devices and endpoints when compared to a similar 802.11g or 802.11b setup due to the use of multiple antennas, 802.11n achieves greater speed through the use of a wider, double wide radio channel. What this means in plain english is that introduction of an 802.11n access point is twice as likely to result in interference with existing 802.11b/g networks as introduction of an 802.11b/g access point. Furthermore, since there are only three non-overlapping radio channels, expect to see real-world performance in urban and up to 1/2 acren lot suburban settings to suffer significantly for everyone as the marketing machines of Linksys and their ilk drive up demand for 802.11n products. IMHO, only those few consumers with high speed file / video transfer needs and uber-mansions of 5000 square feet will actually benefit from 802.11n technology. However, like the iPhone (see other blog entry), this isn't about need, is it? It's about creating demand and getting to consumer to scratch the itch called desire...
