Do all Cisco access points require licenses and stop working when expired
Do the mobility express come with licenses?Not a bad option, if you can buy the hardware right, so as to avoid excessive licensing fees. For a controller-less option, Aironet has Mobility Express, which is an embedded controller, available in mostly all of their current-gen APs (18/28/38/4800 and 9000 series APs).
Yes the 3800 up are expensiveME is free, and can be run from 1800 series and higher APs for up to 50 APs and 1000 clients. It's not as fully feature rich as WLC, in the same way Unleashed isn't as fully feature-rich as ZoneDirector, but the differences are growing ever more negligible, at least for most small/flat networks. I do find ME a bit more of pain to setup, and although Unleashed isn't quite as feature-rich, I find Unleashed easier to run. Fewer touches required; aka "just works" for often. Bang-for-the-buck with hardware itself, I also prefer Ruckus for their radio performance. You can likely buy as much performance from Cisco (performance slightly more?), but you'd need to be up in the 3800/4800/9200 ranges to approach it, and the cost to do so may be quite prohibitive. It's been a while since I checked current street pricing and/or eBay availability, so perhaps I stand corrected.
All that said, I am only one guy, so I'd encourage you do your research on the two systems via their websites, forums, white-papers, reddit/r/networking and /sysadmin, etc.
