All these wireless devices, "smart" TV's, etc are wonderful if you have a consistent high speed link. Sometime, in a good area my AT&T 4GLTE streams fine with no glitches/burps.
Even then, unless you on an "all you can eat" plan you will burn thru your monthly allocation VERY quickly. I have a 20 GB allowance monthly, and it goes really fast.
Supposedly, Dish Network and others are working toward phasing out all satellite based programming in favor of an all cell based distribution network.
