I'm had some aquintance with this technology and participated once in 
WiFi network rollout on a relatively big stadium. All these wifi 
controllers have their limits that in my understanding are significantly 
lower than mobile networks. You can cover one building or campus, but 
how about the next building on the street? It it's owner has a different 
system it may be difficult to connect them even aside of bureaucratic 
reasons.
The main asset of wireless networks is their infrastructure and coverage 
that they were building from 90-s. If you have the network that covers a 
large area you can deploy any technology that fits in it. Definitely 
people from mobile networks have their own way of thinking as well as 
transport and telephony engineers but if wifi could satisfy all the 
requirements they would probably be deploying it. Do you remember Wimax? 
At that time it was better for data then mobile networks but probably 
demand for data services wasn't big enough at that time and then new 
specs were developed that partially used existing mobile technologies. 
I'm not a protagonist of mobile networks as I'm working in fixed 
networks field, but you can't ignore the fact that at the moment they 
have widest coverage, not the best everywhere but the most unversal 
service, non-elastic demand and the best prospective for future growth.
