BART Wi-Fi Access Moves Closer in Bay Area

By Glenn Fleishman

WiFi Rail may sign contract with Bay Area Rapid Transit soon: That’s typical marketing fare from many companies, to pre-announce deals, but a BART official confirmed the state of negotiations in this Sacramento Bee article. I had a long talk with the WiFi Rail folks a few months ago, and they sent me some fascinating video of a live four-way video chat with three participants communicating from moving trains.

Their technical description of what they’re doing makes a lot of sense, and if they can pull off their trial work in a production environment, they will have a set of patents and products that will likely be the model for deploying subway and train Wi-Fi in urban areas around the world. Yes, that’s a big claim; but they have a unique and interesting solution.

The company told the Bee that they would start on heavily traveled underground routes first, with service available within 4 months of a contract. WiFi Rail relies on leaky coax, which is wiring that runs in the tunnel already, and they’ve overlaid Wi-Fi signals on in a way that simulates a very long antenna.

The Bee reports that they’ve raised $1.5m in financing so far with another round of $15m to $20m to close later this year. With a BART contract in hand, I can’t imagine they’ll have any difficulty getting funds. Captive audiences are worth the big bucks.
