FiberTower

FiberTower Corporation (Nasdaq: FTWR) was a wireless backhaul and access transport provider headquartered in San Francisco, California, started in 2000 by four Stanford Business School graduates. The company built carrier-class microwave and fiber backhaul networks across 13 major U.S. markets, holding spectrum licenses in the 24 GHz and 39 GHz bands, and served wireless carriers seeking alternatives to traditional telecom-provided backhaul, with commitments from six leading cellular carriers. FiberTower filed for bankruptcy in 2012 after losing business from major customers including AT&T, and was ultimately acquired by AT&T for approximately $207 million, with the FCC approving transfer of its remaining spectrum licenses and assets between 2017 and 2019, after which the company ceased independent operations.
