Band 2 5x5 is standard across the city. And usually you can find CA with either band 12 5x5 or band 71 10x10. I dont know if band 71 has always been 10x10 or if its because of that leasing deal with dish. I just got back 2 days ago so I haven't been able to test the network before the lease with dish. The coverage is actually very decent. My job has me driving all over the city all day and I always have a strong signal. The speed is just awful. Its encouraging that the signal is good because all they need now is some more bandwidth/capacity and they'll be good to go.
I just have that "GUT" feeling that it is not going to be as easy as they think to combine the TMobile and Sprint sites. I hope they do not cause issues due to mistakes when they attempt this. I just see some problems jumping up.
