Do you doubt the capability of wifi to serve fifty passengers, or the capability of the mobile uplink to the cell network? Neither of these strikes me as beyond the capability of readily available hardware.
Besides which, on the Greyhound buses I've ridden, most passengers were too busy sleeping, attempting to stay seated given the terrible buffeting of USA-standard interstate highways and bouncy Greyhound suspension, or being too poor to afford a device, to contribute much congestion to the WLAN.
- jeffbee 5y agoFairness in the presence of congestion is a difficult problem and just slapping some single-board computer with two network interfaces in between wifi and cellular isn't going to work. I don't doubt the ability of wifi to deal with a few dozen stations on the air.
- jessaustin 5y agoI've been on buses (and trains, and airplanes) where the wifi worked, in that I was able to read email and browse the web. It's probably OK if not everyone is streaming 8K video the whole trip? Like many other engineering tasks, the answer may just be to massively over-specify each component.
