Securitas car theft detector

Sigfox's low-speed but low-cost network wouldn't work for mobile phones, but it's good for some tasks, and the French company showed many of them at the Mobile World Congress show in Barcelona. This Securitas device, embedded deep in a car's innards, communicates with a key fob to alert people when their car has been stolen.
