Where 5G actually shows up in this city

These pages list the sites where crowdsourced observations report 5G NR, with links back to ZIP, county, state, and carrier views.

Observed 5G NR sites

Truthfulness

5G presence is inferred from the cell layer

Crowdsourced observations show where 5G NR has been seen, not rooftop-level certainty. Treat this as a strong signal rather than a guarantee.

Signal, not certainty

Weak 5G?

Distance and band explain most weak 5G

If 5G feels spotty, check how far away the nearest NR-reporting site is. Mid-band and high-band 5G fade much faster with distance than LTE.

Range varies by band
