Glitchy Taxi Tech Blew Cover On Steamy Dispatch Dalliance
The Register, Friday, March 7th, 2025
The week has ebbed away with embarrassing speed, so here we are again with a fresh installment of On Call, The Register's reader-contributed column that immortalizes tech support stories.
Today, we meet a reader who asked to be Regomized as "The RF Guy" and told us about the time he was called on to investigate a glitching taxi dispatch system.
The dispatch system relied on human operators who took calls from customers and then recorded their pickup location in an application. A Unix controller took that info and sent it over a private wireless network to mobile data terminals in each cab.
The RF Guy was called in to investigate the Unix controller and, as he entered, noticed a room full of busy taxi dispatchers. His attention then focused on the Unix machine, which seemed to be working just fine - it happily picked up messages from the dispatch system and squirted them out to terminals.
The backup controller, however, couldn't do the job.
