Napa Cell Signal Strength
There are 425 map hexes within the census-defined boundaries of Napa. The table below shows the proportion of hexes at various levels of signal strength. Where both 4G and 5G coverage is available, data is drawn from whichever technology offers a stronger signal.
Network | Strong | Decent | Weak | None |
---|---|---|---|---|
AT&T | 5% | 54% | 40% | 1% |
T-Mobile | 39% | 51% | 10% | 0% |
Verizon | 26% | 70% | 3% | 0% |
