Steve, It would depend greatly on the system you are using. With the Aruba Wireless system A/B/G coexist very well with N in the same building. The Adaptive Radio Management 2.0 steers users to the best AP for their card's abilities. It will sense and adjust power and channels automatically. We are currently in a phased rollout of N all over campus, we simply place them where they are needed and ARM handle the rest.
One caveat that I would warn you about is that most N AP require more power than an ABG would so if you are using power injectors you may need to upgrade those at the same time. If you are using injectors that are 802.3af you will probably need to replace them with 802.3at compliant injectors.

Beyond Meru's suggestions based on how their tech works I still think it is a good idea. User experience would be consistent for the whole building instead of only having better connections in the strategic locations. I also have concerns if bonded channels are deployed on N near standard A APs. -jim On 6/3/2010 9:03 AM, Steve Hess wrote: > For anyone who has done a phased deployment of 802.11n gear to replace b/g/a, what have you found to be most effective, a whole building (or floor perhaps) approach or putting N in strategic locations with nearby b/g/a AP's? Any gotcha's or learning experience with either approach? We're an Alcatel (Aruba) shop so direct experience with that gear would be great. > > > Thanks, > > Steve > > -- > ----------------------------- > Steve Hess > Network Administrator > Wheaton College > Phone: 508-286-3404 > Fax: 508-286-8270 > ----------------------------- > > > ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. > -- James Eyrich Team Lead Network Design Wireless Service Manager CITES - Networking - Network Design and Support - Network Design Group University of Illinois eyr...@illinois.edu 217-265-6867 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
