This slide reviews some of the current market trends related to the Internet of Things (IoT). The IoT describes how physical objects are connecting to the internet, a simple example being the thermostat at home that can now be controlled via a cell phone through the internet. It is estimated that 6 billion such everyday physical objects will be connected to the IoT by 2020. This means that the IoT is not just a fad or a market trend, but a real commercial reality, with a lot of money involved in it. Sensor-based systems connect the real world to the IoT. These systems must operate interactively with each other, and also autonomously. They typically do so using wireless communication. These sensor-based systems for the IoT must also be very low power so that they can run on batteries for a long time. Bluetooth Low Energy, or BLE, has become a de facto standard for low power wireless in the IoT market. Over 1.2 billion Bluetooth Smart Ready products were sold in 2013 alone. These include products like the iPad, the iPhone, MacBook, Android and Windows phones, and also laptops and desktop computers, which means that there is a whole ecosystem of hosts to connect to very easily. BLE is designed for low power sensor-based products such as wearable electronics, medical devices, and home automation devices. IoT products require sensor-based BLE systems. Shown on this slide are a few examples of IoT products. The first example is a fitness monitor which is an example of a wearable electronic device, the second is a heart rate monitor, a great example of a medical device, and a third example is a deadbolt lock, a home automation device, that connects to the internet and allows the user to interactively and remotely unlock a door.
