Cell Tower Map & RF Exposure in Boston, MA
Carriers Operating in Boston
Boston Nationally
With an RF score of 74, Boston ranks among the lowest 10% nationally for cell tower exposure — significantly less wireless infrastructure than most US cities.
5G in Boston
Boston has 1544 active 5G towers, accounting for 33.3% of the local network. T-Mobile 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 Boston's Tower Density Means for Residents
With 96.1/mi², Boston has very dense tower coverage. Most residents live close to multiple towers, and scores range widely from 10 to 100. Checking your specific address is especially important — even moving a few blocks can make a meaningful difference.
Boston's RF exposure is rated High
RF exposure is high across much of the city, with scores ranging from 10 to 100. Some homes are significantly more affected than others — search your address to understand your personal exposure.
What This Means for You
For a city of 675,647 people, Boston has a high concentration of wireless infrastructure — about 68.7 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 Boston, MA
How Power Lines Affect Boston Residents
Boston has 35 transmission lines and 24 substations within 5 miles of the city center. This includes 8 lines 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 Boston
With 24 substations in the area, Boston 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.
Boston's ELF exposure is rated Low
ELF isn't the main concern here — cell towers contribute far more to Boston's overall EMF picture. Most residents are far enough from power infrastructure that it has minimal impact.
RF vs ELF in Boston: Cell towers are the clear dominant factor in Boston's EMF environment (RF: 74 vs ELF: 16). Choosing a home away from tower clusters will have the biggest effect on reducing your overall exposure.
What This Means for You
Boston 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 Boston Compares: Cell Towers & EMF Scores
Boston has a notably high EMF exposure score of 74, significantly above both the Massachusetts state average of 57 and the national median of 45. While the city ranks 4th out of 5 Massachusetts cities for EMF levels, cities like Lowell offer substantially lower exposure at 32, potentially providing a more EMF-conscious option for residents concerned about electromagnetic field intensity.

Studies have found measurable effects on sleep quality from RF-EMF exposure, though effect sizes vary.
Some researchers recommend lower limits for children, citing developing nervous systems and longer lifetime exposure.
Many choose to minimize exposure based on the precautionary principle: when science is uncertain but consequences may be significant, reducing exposure is reasonable.
