Following the trail of discussion about 802.11n, I wouldn't be buying 802.11n before 802.3at (AKA Power over Ethernet PLUS) gears are on the market. By then, 802.11n vendors should have only one Ethernet port to the AP. One port will bring savings on PoE injectors, Cabling, and even switchports (if you were planning to etherchannel those two 100 Mbps ports to one AP). After all, a 48 ports 10/100/1000 switch is only 50% more expensive than a 10/100 (in the Cisco world), one more reason to only have one cable from the switch to the AP!
Last thing: According to a few websites, 802.3at will work over regular cat5. Best, Philippe Hanset University of Tennessee ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
