Cell Tower

A cell tower is the vertical structure on which wireless antennas are mounted, and in data terms it is the unit of inventory that tower datasets count. This slice contains three provenance models for that unit. Municipal GIS point layers — Austin, Baton Rouge and Los Angeles among them — publish permitted structures as open data. Data.gov's Cell Tower Datasets Catalog returns 46 datasets for the query "cell tower", and its Antenna Tower Datasets Catalog tags records with cell towers, antennas and wireless facilities. OpenCellID distributes bulk downloads tagged cell towers from opencellid.org/downloads, aggregating crowdsourced observations. TowerMaps' US Cell Tower Database is the commercial aggregation, with 600,000+ antenna-site records. Which of these a buyer picks determines whether a count means permitted structures, observed signals or commercial inventory.

Tower data provenance decides what a count means. Municipal GIS layers capture permitted structures, OpenCellID aggregates crowdsourced observations, and TowerMaps sells 600,000+ antenna-site records — three different answers to "how many towers are in this market". only 22.6% of cataloged datasets update daily, so a tower count without a collection date is an unverified claim.

Use these checks before you rely on a source's treatment of this term:

1. Pin down the unit of record: a structure, an antenna installation or an observed signal — collocation means one structure can host several carriers.
2. Check provenance against the artifact: municipal GIS point layers for cities like Austin, Baton Rouge and Los Angeles are permit-derived, while OpenCellID bulk downloads are crowdsourced observations.
3. Test the inventory claim against a named number — TowerMaps reports 600,000+ antenna-site records, so ask any vendor for an equivalent count and its as-of date.
4. Confirm delivery and tags: the Data.gov catalogs tag cell towers, antennas and wireless facilities, and OpenCellID serves bulk downloads from opencellid.org/downloads.

Where to see it in context: telecom-tower-reits data.
