RG1, I too have been hoping for the TMO $50/50Mbps plan but I think they are focusing on rural areas. There is another option, Sail Internet (https://www.sailinternet.com/
). They use mmwave to deliver to your house. I ping'd a Tina who I saw responding to folks in Yelp asking "When can I get Sail?". She responded and had me meet with a Javier. They are looking for neighborhood champions to help them find tall buildings (preferably Multi Dwelling Units) to deliver Fiber to and then they can put transmitters on top and deliver to the surrounding neighborhood. I've found a few and given them the info and I'm hoping this will allow them to get Sail into my neighborhood. They claim 100-200Mbps down, 50-100Mbps up for $55/month.
PM me if you'd like the contact info.
