This phrase “Internet of Things” is making big rounds these days, specially this week at CES (Consumer Electronic Show), Las Vegas. Not sure who came up with this, maybe Cisco in one of their self-serving predictions of the enormous growth of devices connected to the Internet (from about 10 billion today to 50 billion by 2020) and hence the need for their networking gear. John Chambers will elaborate this opportunity at CES in a keynote speech tomorrow. Gartner puts the number of connected devices at fewer than 30 billion, but sees $309 billion in additional revenue for products and service suppliers by 2020.
