Fresno Nationally

Fresno's RF score of 46 falls in the middle range nationally, roughly in line with the typical US city.

5G in Fresno

Fresno has 62 active 5G towers, accounting for 24.5% 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 Fresno's Tower Density Means for Residents

With 2.2/mi², Fresno has sparse tower coverage. Though towers are spread out, EMF scores in Fresno 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.

Fresno'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 4.6 towers per 10,000 residents, Fresno 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 Fresno, CA

100–229 kV

Under 100 kV

How Power Lines Affect Fresno Residents

Fresno has 14 transmission lines and 10 substations within 5 miles of the city center. ELF exposure drops off sharply with distance. Homes more than 500 meters from a transmission line or substation typically have very low ELF levels, while homes within a few hundred feet may experience noticeably higher exposure.

Substations Near Fresno

With 10 substations in the area, Fresno 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.

Fresno's ELF exposure is rated Low

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

RF vs ELF in Fresno: Cell towers are the clear dominant factor in Fresno's EMF environment (RF: 46 vs ELF: 21). 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 Fresno Compares: Cell Towers & EMF Scores

Fresno's EMF exposure sits exactly at the California state average of 46, positioning it in the moderate range and ranking 33rd among the state's 61 cities. While not a low-exposure location, Fresno offers relatively typical electromagnetic field levels compared to other California regions, with cities like Temecula and Murrieta showing notably lower readings for those more concerned about EMF sensitivity.

EMF Exposure & Health

What research says about EMF exposure at levels found in Fresno

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.

Tips for Fresno

�� Choose housing in northwest Fresno (near Woodward Park), which has lower tower density and reduced EMF exposure compared to downtown areas.

�� Install RF-blocking window films on east and south-facing windows to mitigate signal penetration from the higher concentration of 5G towers in central Fresno.

Cell Tower & EMF FAQ for Fresno

How many cell towers are in Fresno?

Fresno has 253 registered cell towers, of which 62 are 5G. That's a density of 2.2/mi² across the city's 115.8 square miles.

Is 5G available in Fresno?

Yes, Fresno has 62 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 Fresno?

Fresno's overall EMF score is 52 out of 100 (Elevated). This breaks down into an RF score of 46 (cell towers & wireless) and an ELF score of 21 (power grid). Scores range from 2 to 100 across the city, so your specific location matters.

How does Fresno compare to other cities in California?

Fresno ranks #25 out of 152 cities in California for EMF exposure (lower rank = less exposure). Some of the lowest-exposure cities in the state include Temecula (24), Santa Maria (27), Santa Cruz (28), Murrieta (28), Santa Barbara (29).

Are there power lines and substations near Fresno?

Fresno has 14 high-voltage transmission lines and 10 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 Fresno is 21 out of 100. Use the map above to see exactly where power grid infrastructure is located.

Which parts of Fresno have the lowest EMF?

EMF scores across Fresno range from 2 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.
