Cary Nationally

Cary's RF score of 56 falls in the middle range nationally, roughly in line with the typical US city.

5G in Cary

Cary has 69 active 5G towers, accounting for 18.5% of the local network. AT&T leads 5G deployment in the area. The network is still primarily 4G LTE, but as 5G expands, more neighborhoods will have higher-frequency antennas nearby. Searching your address shows which towers — including 5G — are closest to your home.

What Cary's Tower Density Means for Residents

With 6.2/mi², Cary has moderate tower coverage. Some neighborhoods have multiple towers nearby while others have very few — and it shows in the data. Scores in Cary range from 10 to 100, so your specific address matters a lot.

Cary's RF exposure is rated Elevated

Cell towers are the primary driver of EMF exposure in Cary, and many residents have elevated RF from nearby infrastructure. Search your address to see how your specific location compares.

What This Means for You

For a city of 182,659 people, Cary has a high concentration of wireless infrastructure — about 20.4 towers per 10,000 residents. Your personal exposure depends on how close towers are to your home, especially to bedrooms. Search your address to see exactly which towers affect you.

Power Lines & ELF Exposure in Cary, NC

230–344 kV

Unknown Voltage

How Power Lines Affect Cary Residents

Cary has 24 transmission lines and 20 substations within 5 miles of the city center. The highest-voltage lines in the area carry up to 230 kV. ELF fields drop off sharply with distance — most homes beyond 300-500 meters from a transmission line see very low exposure. But for homes closer than that, especially near higher-voltage corridors, the impact can be significant.

Substations Near Cary

With 20 substations in the area, Cary 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.

Cary's ELF exposure is rated Low

ELF isn't the main concern here — cell towers contribute far more to Cary's overall EMF picture. Most residents are far enough from power infrastructure that it has minimal impact.

RF vs ELF in Cary: Cell towers are the clear dominant factor in Cary's EMF environment (RF: 56 vs ELF: 23). Choosing a home away from tower clusters will have the biggest effect on reducing your overall exposure.

What This Means for You

Unlike cell tower RF, which is spread across many towers, ELF exposure is very location-specific. You could live a few blocks from a power line and barely notice it in your score, or live right next to one and see a significant impact. Check your address to see if any are close enough to affect your home.

How Cary Compares: Cell Towers & EMF Scores

Cary's EMF exposure score of 56 is notably higher than North Carolina's average of 44 and places the town in the upper tier of electromagnetic field exposure within the state. While Cary ranks ninth among North Carolina cities for EMF levels, its score still exceeds both the state and national medians, suggesting residents may want to consider mitigation strategies or explore lower-exposure neighborhoods within the region.
