5G in Waltham

Waltham has 383 active 5G towers, accounting for 29.3% 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 Waltham's Tower Density Means for Residents

With 50.1/mi², Waltham 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.

69

Waltham's RF exposure is rated Elevated

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

What This Means for You

RF exposure from cell towers drops sharply with distance. In Waltham, scores range from 10 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 Waltham, MA

4
345+ kV
1
230–344 kV
9
100–229 kV

How Power Lines Affect Waltham Residents

Waltham has 14 transmission lines and 7 substations within 5 miles of the city center. This includes 4 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 Waltham

There are 7 substations in the area, where high-voltage power is stepped down for local distribution. Like transmission lines, their ELF fields drop off quickly with distance. If you can see a substation from your home, it's worth checking your address to see how it affects your score.

11

Waltham's ELF exposure is rated Very Low

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

RF vs ELF in Waltham: Cell towers are the clear dominant factor in Waltham's EMF environment (RF: 69 vs ELF: 11). Choosing a home away from tower clusters will have the biggest effect on reducing your overall exposure.

What This Means for You

Waltham 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 Waltham

EMF

Electromagnetic fields from cell towers and power lines. Waltham's combined score: 70/100.

RF

Radio frequency from wireless infrastructure. Waltham has 1308 cell towers (383 are 5G) → RF score: 69.

ELF

Extremely low frequency from power grid. Waltham has 14 transmission lines and 7 substations → ELF score: 11.

EMF Exposure & Health

Waltham's Elevated 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 Waltham

How many cell towers are in Waltham?
Waltham has 1308 registered cell towers, of which 383 are 5G. That's a density of 50.1/mi² across the city's 26.1 square miles.
Is 5G available in Waltham?
Yes, Waltham has 383 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 Waltham?
Waltham's overall EMF score is 70 out of 100 (Elevated). This breaks down into an RF score of 69 (cell towers & wireless) and an ELF score of 11 (power grid). Scores range from 10 to 100 across the city, so your specific location matters.
How does Waltham compare to other cities in Massachusetts?
Waltham 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 Waltham?
Waltham has 14 high-voltage transmission lines and 7 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 Waltham is 11 out of 100. Use the map above to see exactly where power grid infrastructure is located.
Which parts of Waltham have the lowest EMF?
EMF scores across Waltham range from 10 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.
