Many of the projects under way are solving today's problems: for example, Katabi presented MegaMIMO, which scales wireless capacity by allowing multiple individual senders of data to transmit concurrently to multiple receivers on the same band.
But others are meeting needs still some years in the future. CarSpeak is billed as a communication system for autonomous driving, as in Google's driverless car project. CarSpeak lets multiple self-driving cars share information about objects that are hidden from one vehicle but visible to the sensors of another nearby. And given the promised improvements in mobile technology more broadly, chances are we'll be more absorbed in our devices 10 years from now -- so the safer choice may be to leave the driving duties to the car.
