Signal and area summary
Sites and spectrum bands
Sites can support more than one band. Spectrum presence indicates capability, not a promise of service, speed, or indoor reception.
How this coverage rating is built
FCC infrastructure: 2 grouped sites from 7 cellular license records.
OpenCellID: 39 grouped crowdsourced sites from 40 database records.
FCC BDC: 683 distinct nearby filing cells inform the carrier-reported area percentages when available. The visible map layer defaults to 5G-NR; the summary percentage considers any technology available in the local filing data.
Rating: The evidence grade blends site density/proximity, crowdsourced signal when present, and carrier-filed coverage. Missing sources are excluded rather than treated as zero.
Limitations: Estimated signal uses free-space path loss and cannot fully model terrain, foliage, building materials, congestion, maintenance, or device differences.

About AT&T Coverage Near Upland, CA 91784
Evidence suggests usable AT&T coverage in Upland, CA 91784. Our analysis combines FCC cellular license records, crowdsourced OpenCellID observations when available, and carrier-filed FCC BDC coverage. Within 5 miles of Upland, CA 91784, those sources resolve to 41 grouped AT&T sites; the nearest is approximately 0.4 mi away.
Where a crowdsourced reading is unavailable, signal is estimated with Free-Space Path Loss (FSPL) and FCC-registered or band-typical effective radiated power (ERP). The best available site value is -45.2 dBm. It is a planning estimate, not a promise of device-level or indoor performance.
We found 40 sites with mid-band spectrum. Carrier filings and device observations provide additional context, but band presence alone does not confirm active 5G.
