MMDS is a very interesting technology and a great way to avoid the state's cable laws now. most states do not include MMDS as part of their state wide agreements. Ohio is one of them. For the most part all one has to build is afford to buy/lease or obtain the MMDS spectrum from the FCC or someone else and then build out the network with a tall enough tower and contact DishNetwork or DirecTV and start reselling.
That's about all they're doing for TV.
For Internet they're using MOT CMTSs and MOT cable modems and sending the signal wirelessley and works fine.
