San Rafael Cell Signal Strength

There are 394 map hexes within the census-defined boundaries of San Rafael. 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	8%	42%	49%	1%
T-Mobile	28%	45%	24%	4%
Verizon	15%	76%	9%	0%

For most purposes, decent signals are perfectly sufficient. Weak or non-existent signals cause far greater degradation in user experience.
