Internet of Things
The Earth is being covered by an ever-expanding mesh of networks and sensors that form the Internet of Things (or the Internet of Everything). Think of the IoT as the network of all digitally accessible objects, estimated at 15 billion in number today, and expected to grow to more than 50 billion by 2020.
But what makes this even more powerful, is that each of these connected devices, are themselves made up of a dozen sensors measuring everything from vibration, position and light, to blood chemistries and heart rate.
Imagine a world rapidly approaching a trillion sensor economy where the IoT enables a data-driven future in which you can know anything you want, anytime you want, anywhere you want. A world of instant, high-bandwidth, communications and near perfect information.
The implications of this are staggering, and Raj was asked to share his top five breakthroughs from the past three years to illustrate some of them.
(Raj Talluri, Senior VP of Product Management at Qualcomm, who oversees their Internet of Things (IoT) and mobile computing businesses puts IoT into context.)
Here are the breakthroughs Raj identified in Networks and Sensor technology from 2012-2015
Emergence of Continuous Low-Power Always-On Sensors
One of the major advances from the past three years has been the proliferation of “always on” sensors.
As Raj explains, “You’ll be amazed how many of your phone sensors are always on. If you look at your phone, there were times when you had to press the button to say hello Google or hi Siri. Now, you don’t. You just talk to it and it figures it out.”
“This has been made possible because you’re now able to make very low power sensors that listen to you all the time, keyword detect and do the data processing.”
Smartphones Drives Sensor Volume at Low Cost
The number of sensors in your smartphone today have exploded. Raj continues, “We are now seeing 10, 20 and even 30 sensors embedded in our smartphones. Things like proximity sensors when you pick your phone up, gyros, cameras, depth sensors and so on. This has really driven down cost and driven the discovery of new sensors, because there are a billion smartphones [sold] every year. It’s a huge opportunity.”
A billion phones means 20 billion+ sensors – and we are headed towards a trillion sensor economy.
“Systems” Fuse Continuous Sensor Data & Cloud Processing
Seamless integration of processing is happening in the cloud and on your device. Raj explains, “When you say, ‘Okay, Google,’ a part of what happens next is on the phone and a part is on the cloud. You don’t really know where the processing is being done, on your device or on the cloud, the hand off is seamless.”
4K Video Format Goes Mainstream
4K screen resolution is close to the point that the brain is unable to notice pixels. As such, somewhere between 4K and 8K, virtual reality become visually equal to visual reality.
Raj explains how this technology is exploding: “If you buy a 4K TV and watch 4K content, it’s very hard to go back to 1080p. It almost feels like you were watching a VHS tape when DVDs came out. Today, if you look at what we’ve done at Qualcomm in the high-end processors space, we shipped over 200 to 250 million processors that actually record in 4K.”
Opening of Sensor APIs to 3rd Party Apps Development Community
The reality is that the majority of phone apps now come from third party developers. This explosion in apps (perhaps 50 to 100 per phone) is only possible because of (i) the opening of the APIs for the sensors in the devices and (ii) the community of developers that has emerged as a result.
Here are Raj’s predictions for the most exciting, disruptive developments coming in Networks and Sensors in the next three years
Wireless Network Densification (4G/5G): Cost / Megabit Plummets
The cost per megabit of connection is going to plummet – essentially nearing “free” in the very near future.
Raj expands, “Already in places like Indonesia, we find that people are actually getting data plans at a price of $5 a month. In most of the world, the cost per megabit is extremely low as the cost of launching networks is plummeting.”
Emergent Peer-To-Peer Tech Drives Automotive Communication & Safety
Soon all of your devices at home and work (screens, thermostats, DVRs, computers, even cars) will automatically connect seamlessly. You won’t have to make conscious decisions about how to connect your washing machine. When it finishes washing the clothes, you will get a notification on your phone.”
Global Internet Connectivity via Satellite Plummets in Cost
Qualcomm, in partnership with Richard Branson, are working to deploying a 648 satellite constellation called OneWeb. Raj explains, “Global Internet connectivity through satellites is finally going to happen… Just think about three billion new people coming online at a megabit per second. It is going to be completely different kind of experience.”
Exponential Growth in Connections to Internet from Various Devices – Personal/Home/Cities
For Raj (and most of us) it’s more like 50… your TVs, your set top boxes, phone, iPads, Nest, cameras, light bulbs…
“In the next few years, the number of things that will be connected to the Internet at any given point of time in your life is going to be so huge that the way they work is going to be very different. You won’t need to reach for your phone to do something. Coupled with sensor networks, you’ll just be able to speak and ask for what you want.”
Major Improvements of Head-Mounted User Interfaces with Rich Bandwidth and On-board Sensors
Over the next three years, we’ll see rapid uptake of VR and AR headsets, each with 4K displays and cameras, and packed with a suite of sensors connected by high bandwidth communications to the cloud. The result is that each of us is wearing an incredible User Interface with high-speed communications that will make our virtual experiences so good that you won’t need to travel to experience something.”
