I have thought about having all AP's wired straight back to the core switch to provide maximum speed....where within the 100M radius. This does seem a 'messy option' though but would surely provide the fastest speed and no work other than purchasing for example 2 X 24 port GB modules for our HP 4108GL and the actual physical cabling would be required. Dong it the traditional way of just having the AP points wired back the nearest cabs wouldn't be quick enough with our current set up.
    Think of a wireless AP as a 30 port switch. To function correctly it will need a 1GB back to the (actual) switch in order to serve 30 connections. It's fine running them from near edge switches if you have 10GB/s backbone - otherwise run them all back to the core or you will be asking for trouble if the AP's all get loaded. If you have a large site you may have no option other than 10GB core if you want to avoid problems.

    Our core is serviced by an Extreme 8810 running to 8 Extreme x450e switches at 10GB then to lower use cabs at 1GB to 9 DLink 1224TPs. I'd agree with CyberNerd the need for a good link back is needed our Aruba AP65s only connect at 100mb back to the closest switch which does have a knock-on effect with performance. We have now got a new sixth form centre build going up over the course of 9 months and this will let us experiment with a new N standard wireless solution however I need OM3+ from the existing site to the new build and for this project I think it needs to run directly from the core instead of the closest edge switch (should prove expensive) looks like 40GB connections are easily available for core switches now 10GB connections everywhere may become a reality in the next 5 years with 100GB becoming the infrastructure standard soon.

    We are using a ring of 4 fiber (1Gbit/s) lines connected with LACP. Switch is HP E4800. 10Gbit/s isnīt needed and wonīt be within the next 5 years. LACP with 1Gbit/s modules is cheaper...

    Rather depends on how many connections you need. Good luck if your expecting 15 AP's with 30 connections each to run off a gigabit near edge switch with only 1 or 2 GB uplinks
