We're in the process, right now. We've got basic "coverage", and in the classrooms we've tried to accommodate for higher density. However, with 3, 4 or more devices per student - or person really - we're looking at a refresh of the 1,400 APs we have now and effectively doubling that - or more. Sure, this is a "back of the envelope" budget number, but it's also based on the demands from our user community with multiple devices, buildings with LEED certification that cell phones won't work inside well, and RF doesn't penetrate concrete and rebar filled cinder block walls very well. Shrink the cell, the AP doesn't have to transmit as high of a power, and there's hopefully less interference from the Xbox controllers, microwave ovens, cordless phones, etc. etc. etc.
We basically did coverage based design with ROWN v1.0 back in 2005, and have migrated in the new construction to capacity based design. With a refresh of network hardware (due to EOS/EOL notices from multiple vendors on our specific hardware standard models), we're looking to make it another 8 - 10 years with a new focus on capacity. It's not as if users are going to quit having multiple devices. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
