It is hard to imagine life without your Smartphone – you have come to rely on it so much – for your work; to stay in touch with family and friends; to capture and share those special moments; to find your way around in a new neighborhood. Did you ever wonder how and when all this happened? Or how and when GPS sensors came to be in your cell phone? In this course, we will explore the convergence of multiple disciplines leading to todays’ Smartphones. You will learn about the birth and evolution of Telephony Networks, Broadcast Networks (TV and Radio) and Consumer Electronics. We will discuss the impact of Internet, (multimedia) content, smartphones and apps on everyday lives. We will then look at how this emerging platform called the Internet of Things – wherein billions and trillions of devices communicating with each other and “the cloud” – could enable unprecedented, innovative products and services. Take this course if you want to understand what great new advances in mobile-enabled products will be coming our way! Learning Goals: This course provides a core grounding in how science and technology have developed to enable the Internet of Things – in a way appropriate for any learner. For those interested in developing further hands-on expertise in designing and developing for the Internet of Things, this course will provide a context to the discoveries and converging technologies that will springboard the next round of innovations. After completing this course, you will be able to: 1. Compare how the telephone system works (that is, peer-to-peer networks) with how media delivery works (that is, broadcast/multicast networks). 2. Explain the tradeoffs between circuit switched networks (that is, dedicated resources) and packet switched networks (that is, shared resources). 3. Tell interesting stories about key innovations that transformed the communications, entertainment and consumer electronics industries. 4. Explain how email, YouTube, SMS, etc. work. 5. Find resources for those wishing to do more of a “deep-dive” into the above topics.

Hey guys, welcome back.
In this clip, I'm gonna talk about what the heck IoT is all about.
You've heard this done so many times, Internet of Things.
First, let me start with, what is this thing in Internet of Things, right?
What is a thing?
So let's kind of dream up all of the objects in our house,
the lowly lawn sprinkler, the proverbial light bulb.
We can't talk about IoT without bringing up the light bulb.
There'd be a d'état.
So I put it in there.
Maybe your glasses, okay, your reading glasses.
And a bottle of whiskey, right?
These are things that are in your house.
Without any connectivity, they're kind of plain.
But, let's assume each of these guys have some sort of connectivity.
They can kind of transmit a little bit of data or receive some data or both.
Suddenly, they become interesting.
Let's take an example.
So in other words, they have some sort of connectivity.
I'm not talking about in a full blown IP, but
they have some forms of short range communication where they can occasionally
wake up, say something about themselves to a neighboring device or
to a server or interact with a human, all kinds of possibilities.
They don't need actual power, they can be battery powered.
Let's take the sprinkler for example.
It could be combined with it could have sensors to measure
the moisture in your soil.
So it can shut itself off when there's rain.
It only comes on when the soil is sufficiently dry, the light bulb.
I mean think of landscaping in your yard, right?
You can now set it to come on at dusk and and go off when it's sunrise.
Those things already exist but, you know, you can push to another level.
Your reading glasses, right?
Think of Google Glasses.
I'm not gonna say anything more about it.
I know there are lovers and haters.
And finally a bottle of whiskey.
Hey, what can you do with a bottle of whiskey?
Actually Johnny Walker did some cool stuff with a bottle of whiskey.
They made the labels pretty smart.
It has a little antenna in it.
It can detect number one if the bottle has been opened or not.
They realize a lot of people when they are about to purchase a bottle,
they are researching in their phones, should I buy a single malt or blended, and
the research is happening typically within five feet of the bottle.
And so this smart tack and interact with your phone.
It knows I haven't been opened.
There's someone looking at me to buy me.
I haven't been opened yet.
That's another scenario.
So determines the state so it can someway communicate.
And also, and if it's been opened, it knows that and
it communicates it to your phone it's like it knows it's already been bought, so
interaction would be slightly different.
It's kind of like I should say when you're dating someone and
you get married, it's different interaction, right?
You already have someone, least kind of bottle.
And also the other cool thing for Father's Day.
You can create a customized thing for your dad, a video message, and
he scans the bottle and he gets to see what you have planned for him.
Anyway, bottom line, these things when they have some Internet connectivity
become Internet of things then new possibilities emerge.
Here's data which suggest from it's not my chart, but
borrowed from my garder, how these things are growing, the growth rate.
If you look at the chart the red is typically the personal computers,
which are connected to the Internet.
They kind of flattened out.
Smartphones are growing.
More smartphones, tablets.
But if you look at the one,
the biggest growth is going to be in this Internet of Things.
These dumb things which shouldn't have connectivity suddenly have connectivity.
And that's going to be exploding.
They say about roughly 50 billion devices by 2020.
So take it for what it's worth.
The exact numbers may not matter, but the fact is it's growing at an alarming pace.
Let's get back to what the heck is IoT?
Let's go back maybe 15 years.
We had the television.
It was still broadcast, you are watching what was fed to you.
TV was not connected to the Internet until the set up boxes came around.
When I was growing up India I was telling my American friend hey man,
we didn't even have a remote control.
So he was asking what?
How do you watch?
Did you have a service industry where someone was changing channels for you?
I said no man we only one channel.
We didn't need a remote.
So that's kind of how I grew up, but now the boxes came around.
You could now control your TV remotely, right?
The smartphones arrived, the apps were there.
Now you started watching TV on your phone.
You could also record shows from your phone.
So in other words, putting the TV on the net created a new
kind of interaction between the smartphone and your TV.
Let's take one step further right, what's the next big thing in your house?
The refrigerator, the fridge, and imagine your fridge being smart.
In other words can become aware of at any times what kind of food items in your
fridge, and it can let's say communicate that to your phone, and
there's a recipe app in your phone, or an Amazon app in your phone which can tell
you, hey, based on what's in your fridge, these are the dishes you can make.
And if you don't have it, let's say you can click order and Amazon certainly,
it can deliver via drones within 30 minutes, once you order.
So you can have your thing delivered to you,
pick up from your drone, make your dish, right?
I mean, I got to tell you, when I was a kid I didn't have a fridge or
the Internet of Things.
But I had good food from my mom.
But this is, I guess, we call progress, like a smart fridge, right.
Let's keep going, the thermostat.
You've heard of companies like Nest, we will acquire,
which can smartly control energy in your house based on different parameters.
The smart toilet.
Yeah, believe it or not, they're making smart toilets.
You may think like, put the toilet on the net.
Who gives a shit?
But, no pun intended, but there are smart toilets.
You can put sensors in the toilet which can analyze the urine and
detect diseases at an early stage and
that can communicate that to your phone or your health provider or what not.
But these do toilets to exist.
I have an idea for Capstone project, maybe you should
create an ad which changes itself Friday night at 9 pm.
Because it knows that's the way it's going to be when you come back from
the bars right?
So, let's keep going.
Put your dog on the net.
Say what the hell, dog you pet on the net.
There was a company called Petcell, which is making these cellphone collars.
You can put it on your dog.
When you call the dog it'll automatically answer and put it on speakerphone,
because he knows you're calling.
You can talk to the dog, it'll hear you talking, and what's it going to say?
Probably rattle the poor thing.
But I don't know if the company is still around,
but that's kind of putting your pet on the net, and
probably if you get telemarketing calls, you can direct it to your dog,
maybe one use of it, next step is fork, a smart fork.
Everyone's trying to lose weight, right?
One thing is your brain, when you're eating,
tells you five minute later then when you get actually full.
So by the time you've overshot, you stuff yourself.
And by the time your brain tells you you're full, you're beyond full.
You're about to explode.
So one thing is to slow down the pace you eat.
So you can stop, right the time you get full.
And this fork, search for happy fork.
Fork.
This company had the idea where it measures, it has sensors,
how many bites you take and can vibrate to help you slow down.
And it's got Bluetooth in there.
It can communicate that to your phone.
At the end of your meal it shows you how many bites you've taken.
Over 200 it says, stop being a pig, and
it can give you feedback on how you're eating.
So as you can see is wide of range of products.
And then who knows what is coming next, right?
Have you heard of Volkswagen beating the system by shutting down the emissions
when the tests are happening.
So devices are getting smarter and smarter.
It doesn't matter what the next device is
our goal is to put you in the middle of it.
Whatever you dream up we want you to be able to build it and
what are the skills you need for that,
that's what this specialization focuses on so we're gonna help you get there.
So that's kind of my version of innovative things and you of course
may disagree with me but kind of roughly hopefully you're on the same page.
