I'm a bit shocked at the Cisco Press CCNA Wireless book...
It lists the ideal CCNA Wireless Lab as follows:
2106 Wireless LAN Controller
1131 AccessPoint
and
Cisco Mobility Express (CME) 526 controller
521 AccessPoint
Who has $2.5k + $1.5k laying around for a hardware lab at the CCNA level?

I was expecting small-medium sized business implementation of 800-series Cisco wireless routers.
...the ideal exam preparation would consist of building a small wireless lab with a 2106 wireless LAN controller and an 1131AP, as well as a Cisco Mobility Express (CME) 526 controller and 521 AP.
