Deloitte predicts that in 2015 one billion wireless Internet of Things (IoT) devices1 will be shipped, up 60 percent from 2014,2 and leading to an installed base of 2.8 billion devices.3 The IoT-specific hardware (which could be a more expensive cellular modem, or a much cheaper Wi-Fi chip) is likely to be worth $10 billion,4 and the associated services enabled by the devices worth about $70 billion.5 Services include all of the data plans that may be necessary to connect a device over a network, the professional services (consulting, implementation, or analyzing the data) and then things like an insurance policy discount for a telematics device in a car or a wearable device for health purposes. 

IoT hardware and connectivity revenues are growing at about 10-20 percent annually, while the apps, analytics and services are growing even more rapidly at 40-50 percent.6 While the press may focus on consumers controlling their thermostats, lights and appliances (from washing machines to tea kettles), Deloitte predicts that 60 percent of all wireless IoT devices will be bought, paid for and used by enterprises and industries. And over 90 percent of the services revenue generated will be enterprise, not consumer.
