Brea Cell Signal Strength

There are 268 map hexes within the census-defined boundaries of Brea. 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	32%	54%	13%	2%
T-Mobile	23%	54%	18%	5%
Verizon	37%	50%	13%	1%
