What is the “Internet of Things”?
• IoT is a conceptual framework
• It’s about enabling connectivity and embedded intelligence in
devices
• Some of these devices are connected today, but MANY are not…
• Not strictly machine-to-machine (M2M) – also machine-to-people,
people-to-machine, machine-to-objects, people-to-objects
• Creates the ability to collect data from a broad range of devices
• Data can be accessed via the cloud and analyzed using “big data”
