Knoxville Cell Signal Strength

There are 2,768 map hexes within the census-defined boundaries of Knoxville. 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	15%	70%	15%	0%
T-Mobile	39%	58%	4%	0%
Verizon	31%	63%	7%	0%
US Cellular	30%	65%	4%	1%
Dish	23%	70%	6%	0%

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

Due to data-reliability concerns, 140 hexes in Knoxville that fall in bodies water, along rivers, or near shorelines are excluded from the table above.
