Where can I learn more about LTE coverage and build out schedules in the US?

Solution 1:

Not much in the way of a major community database of real-world speeds, sadly. Here are some other resources:

  1. Verizon's LTE coverage map
  2. AT&T's HSPA+ coverage map (and overview)
  3. Overview of all major carriers, and another (older)
  4. More general information on current/planned deployments
  5. Verizon coverage map with speed tests - Minneapolis/St. Paul area only.

You might also use the FCC's GIS data to find out more about what towers already exist. Presumably, they're not going to build new towers for LTE - just add antennae to existing sites.
