# Spectrum Buildout Deadlines: free sample (Tensorust LLC)

38,023 construction deadlines still open on live FCC auction licenses, 513 of them due within 18 months, plus 3,737 past deadlines with no construction notice on file.

**Headline:** FCC market-based licenses (PCS, AWS, 600 and 700 MHz, CBRS PALs, C-band, 3.45 GHz, UMFUS and more) carry construction (buildout) deadlines; under FCC rules a license that misses its final deadline terminates automatically.

This repository is a **free teaser**, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has **84,420 rows** and is sold by Tensorust LLC: **[https://tensorust.com/datasets/spectrum-buildout-deadlines/](https://tensorust.com/datasets/spectrum-buildout-deadlines/)**.
