Carriers Operating in Madison
Madison Nationally
Madison's RF score of 44 falls in the middle range nationally, roughly in line with the typical US city.
5G in Madison
Madison has just 12 5G towers so far — a small fraction of the network. Most wireless coverage relies on 4G LTE and older technologies. As carriers like T-Mobile continue rolling out 5G, this will change, potentially shifting RF exposure patterns in the area.
What Madison's Tower Density Means for Residents
With 1.6/mi², Madison has sparse tower coverage. Though towers are spread out, EMF scores in Madison range from 2 to 100 — some pockets sit much closer to infrastructure than others. If you're in one of those pockets, your exposure could be well above the city average.
Madison's RF exposure is rated Moderate
The city average is moderate, but scores range from 2 to 100 — your neighborhood makes a real difference. Search your address to see where you fall.
What This Means for You
With only 4.8 towers per 10,000 residents, Madison has relatively thin wireless infrastructure. Most homes won't have towers immediately nearby — but those that do can see a real impact. Searching your address shows the full picture.
Power Lines & ELF Exposure in Madison, WI
How Power Lines Affect Madison Residents
Madison has 35 transmission lines and 23 substations within 5 miles of the city center. This includes 1 line carrying 345 kV or more — the highest voltage class, which produces stronger ELF fields over a wider area. For homes near these corridors, distance is critical: ELF drops off sharply, but high-voltage lines have a larger impact zone than lower-voltage infrastructure.
Substations Near Madison
With 23 substations in the area, Madison has significant power distribution infrastructure. These are the points where high-voltage power is stepped down for local use. Each one creates a localized ELF field — if you live within a few hundred meters of one, it likely contributes to your score. The map shows exactly where they are.
Madison's ELF exposure is rated Low
Most residents are far enough from high-voltage infrastructure that ELF isn't a major concern. Homes directly adjacent to power lines may still want to check their specific score.
RF vs ELF in Madison: Cell towers have a somewhat bigger impact than power lines in Madison (RF: 44, ELF: 28), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
Madison has some high-voltage (345+ kV) infrastructure nearby, which creates stronger ELF fields over a wider area than lower-voltage lines. If you're close to one of these corridors, it can meaningfully impact your score — the map shows exactly where they run.
How Madison Compares: Cell Towers & EMF Scores
