Meanwhile, though, I decided to answer a question someone asked last week about using XOHM in a moving, metal vehicle. I took my XOHM card onto Baltimore's Light Rail and onto the #27 bus.

Result: In a stopped, metal vehicle, there's essentially no difference in speed. I got blazing speeds of up to 8 megabits down. Yowza.

But once the vehicle got moving, I started getting inconsistent results. The Sprint-approved speed test site, at www.speedtest.net, showed speeds of 5 to 6 megabits down. But my FTP server, which chugged along at 2 megabits while I wasn't moving, dropped to about 700 kilobits.

Of course, you're most likely to use XOHM while sitting still or moving slowly. Hopefully. Please don't surf and drive, people.

I was struck once again by the inconsistency in XOHM's coverage. I hit a dead spot between the North Avenue and Woodberry light rail stops, and also along part of Remington Ave. in Wyman Park. Hopefully Sprint will patch things up swiftly.
