5G in Somerville

Somerville has 1411 active 5G towers, accounting for 31.9% 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 Somerville's Tower Density Means for Residents

With 136.7/mi², Somerville has very dense tower coverage. Most residents live close to multiple towers, and scores range widely from 35 to 100. Checking your specific address is especially important — even moving a few blocks can make a meaningful difference.

78

Somerville's RF exposure is rated High

RF exposure is high across much of the city, with scores ranging from 35 to 100. Some homes are significantly more affected than others — search your address to understand your personal exposure.

What This Means for You

RF exposure from cell towers drops sharply with distance. In Somerville, scores range from 35 to 100, which means your specific location matters more than the city average. Search your address to see what's nearby — especially which direction towers are from your bedrooms.

Power Lines & ELF Exposure in Somerville, MA

8
345+ kV
26
100–229 kV

How Power Lines Affect Somerville Residents

Somerville has 34 transmission lines and 25 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 Somerville

With 25 substations in the area, Somerville 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.

18

Somerville's ELF exposure is rated Low

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

RF vs ELF in Somerville: Cell towers are the clear dominant factor in Somerville's EMF environment (RF: 78 vs ELF: 18). Choosing a home away from tower clusters will have the biggest effect on reducing your overall exposure.

What This Means for You

Somerville 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.

Understanding EMF, RF & ELF

What the scores mean and how they're measured in Somerville

EMF

Electromagnetic fields from cell towers and power lines. Somerville's combined score: 79/100.

RF

Radio frequency from wireless infrastructure. Somerville has 4428 cell towers (1411 are 5G) → RF score: 78.

ELF

Extremely low frequency from power grid. Somerville has 34 transmission lines and 25 substations → ELF score: 18.

EMF Exposure & Health

Somerville's High EMF score means understanding exposure risks is especially relevant

Sleep Quality

Studies have found measurable effects on sleep quality from RF-EMF exposure, though effect sizes vary.

Children

Some researchers recommend lower limits for children, citing developing nervous systems and longer lifetime exposure.

Precautionary Principle

Many choose to minimize exposure based on the precautionary principle: when science is uncertain but consequences may be significant, reducing exposure is reasonable.

Cell Tower & EMF FAQ for Somerville

How many cell towers are in Somerville?
Somerville has 4428 registered cell towers, of which 1411 are 5G. That's a density of 136.7/mi² across the city's 32.4 square miles.
Is 5G available in Somerville?
Yes, Somerville has 1411 active 5G towers. 5G uses higher-frequency RF signals and typically requires more antennas placed closer together, which can increase localized RF exposure.
What is the average EMF score in Somerville?
Somerville's overall EMF score is 79 out of 100 (High). This breaks down into an RF score of 78 (cell towers & wireless) and an ELF score of 18 (power grid). Scores range from 35 to 100 across the city, so your specific location matters.
How does Somerville compare to other cities in Massachusetts?
Somerville ranks #N/A out of 30 cities in Massachusetts for EMF exposure (lower rank = less exposure). Some of the lowest-exposure cities in the state include New Bedford (22), Barnstable (34), Haverhill (34), Beverly (35), Salem (39).
Are there power lines and substations near Somerville?
Somerville has 34 high-voltage transmission lines and 25 substations within the city area. These contribute to ELF (extremely low frequency) exposure, which is measured separately from RF (cell tower) exposure. The ELF score for Somerville is 18 out of 100. Use the map above to see exactly where power grid infrastructure is located.
Which parts of Somerville have the lowest EMF?
EMF scores across Somerville range from 35 to 100, which means location within the city makes a real difference. Areas farther from cell tower clusters and major power line corridors typically score lower. Use the address search above to check specific streets and neighborhoods you're interested in.
