Remember Autonet? The company -- which is best known for providing manufacturers like Chrysler with in-car WiFi hotspot solutions -- is launching a new product designed to replace the key fob and enable low-latency remote vehicle control and diagnostics from any smartphone. Of course, this is nothing new -- car makers have been featuring apps to unlock doors, start the engine and monitor vehicles for some time now. Still, most existing solutions rely on satellite or 2G connectivity and often require the car's computer to be fully booted before responding to commands, which makes for a slow and unreliable experience. Autonet's new system combines in-vehicle hardware, mobile software and cloud services to streamline this process for both manufacturers and owners. More after the break.
