Not the case in, e.g., Bedford NY or New Canaan CT, just checked. These are examples of suburban areas within an hour commute of mid-town Manhattan, where cell coverage is spotty (combination of NIMBY and rolling terrain). Same story for southern coast barrier islands off Long Island. To your point though, the carrier map claims blanket coverage in North Greenwich (S of Merritt Parkway), while in reality along North Rd there are 7 and 8 figure homes that have no cell service from any of AT&T, T-Mobile, or Verizon. Lately I’ve found a quick and dirty viz for coverage is looking at a given carrier’s 5G coverage maps. They need stronger signal for that to work, so it shows the “dark” areas more easily. On the barrier islands mapping from the carriers, you can even see effects of dunes. That surprised me. |
