There is a provision in the regulations somewhere that allows underground/tunnel transmitters on licensed bands without a license, provided certain power limits are honoured outside of the tunnel. Perhaps they are operating under these provisions? K On 10/08/2014 02:11 PM, William Herrin wrote:

BART would not have had an FCC license. They'd have had contracts with the various phone companies to co-locate equipment and provide wired backhaul out of the tunnels. The only thing they'd be guilty of is breach of contract, and that only if the cell phone companies decided their behavior was inconsistent with the SLA..
OK that makes more sense than the private answer I got from Roy. I wondered why the FCC didn't take action if there was a license violation.

From the article: "Among the issues on which the F.C.C. is seeking comment is whether it even has authority over the issue."
Also: "The BART system owns the wireless transmitters and receivers that allow for cellphone reception within its network."
I'm not entirely clear how that works.
