I'm writing these works on a regular run of the ferry from Seattle to Bainbridge Island: I hadn't yet--remarkably--had the chance to try out the regular prototype service that's been deployed on a majority of the Washington State Ferry system's runs. Mobilisa, a company based in Port Townsend, has built and is rolling out the test. A formal RFP will be issued this spring, based on earlier statements, to find a commercial provider that will take over operation, maintenance, and establish fees.
I'm seeing 200 Kbps down and 50 Kbps up, which is pretty good for a moving ferry in a test out in the middle of Elliot Bay. I'm sure Bainbridge commuters are overjoyed: the island is a bedroom community for many downtown workers who managed to buy property out there when it was still considered a bit of a backwater.
