T-Mobile Connectivity and Latency on CalTrain
I commute most days of the week from San Francisco to San Jose on CalTrain. I’ve been very frustrated by the poor signal quality for most of the route. T-Mobile kept insisting that I needed to provide a speed test from a single, fixed location. Given that a CalTrain “Baby Bullet” express train travels nearly a mile in the ~40 seconds it takes to run a speed test (their top speed is 79 MPH), this basically isn’t feasible.
