Mobile devices come in a variety of sealed forms and run mobile-specific operating systems. Devices include smartphones, tablets, wearables, ereaders, and more. OSs are Android, iOS, and a few others to a lesser extent. This episode tours the common mobile devices.
let's make sure we understand what is exactly a mobile device? So, a couple of rule sets. Number one, a mobile device is going to be sealed, it's going to be a single unit and you can't go in and replace memory and add hard drives and stuff like that. very specific operating systems designed for mobile devices. In these days, Android and iOS are the two big front-runners, but there's actually others. which are designed to run on, ready for a term, an embedded system. All of these are embedded systems. By embedded, the operating system to support lots of different device drivers and such, 'cause you're never going to be seeing different hardware in a sealed system. Okay, now that we understand that, there's a few things that you can usually count on in any type of mobile device. For example, it's almost always going to have some kind of wireless connectivity. At a very minimum, they're all going to have 802.11, but they might also have things like for example, Bluetooth or cellular, or Zigbee, or some kind of other type of technology that allows them to communicate with the outside world. They may or may not have wired connections, but if they do have a wired connection, it's probably going to be mainly for charging, it's not going to be necessarily for adding accessories, Okay, now with that attitude in mind, let's start off with the one that we all know and love, and it's a good old smartphone. So this is my personal Android smartphone. So smart devices are either going to be running Android or iOS operating system. There have been a few other attempts like Windows had a mobile operating system They're definitely going to have wifi, well they're phones so they're going to have cellular. But more than that, they're going to have a lot of interesting features. They pretty much all have GPS built into them. They have accelerometers so you can keep track of how many steps you've done. and we've covered those in other episodes. Alright, now if you're going to have a smartphone, Take a look at this. So you'll notice that this is a bumper for this add-on Samsung. The bumper is just a protective case. What it does is protects people like me from dropping these and end up spending lots and lots of money. This particular case is actually kind of cool. If you look down here, I can actually put this, I don't have it plugged in right now, but I can put this on here and I can actually do wireless charging, which is incredibly comfortable. So these are really convenient because I can actually charge things wirelessly. Wireless comes and goes. It was hot for a few years, it kind of lost interest, it's kind of hot again right now, we'll see what happens in another year and a half. You can even, well, the big thing about smartphones is we don't want them to lose battery power, so we're always interested in more battery. So you're certainly going to have battery chargers. My old joke is, I actually remember a time in my life where the endpoints in my life were not USB-C connectors because I've got one in my car, I've got one at my desk in the office. I've got one in my laptop case, I've got one on my bed stand. I've got one in my home office. 'Cause the first thing I do is whenever I'm sitting down anywhere, is I plug in my Pixel and I start charging it again. So lots and lots of battery chargers around. Some people will actually get bumpers with built-in extra battery packs. We see them in all kinds of interesting places. A lot of restaurants for point-of-sale systems. There's actually a string of restaurants in airports where you don't really get a waiter, what you get is one of these and you just order off of it and then somebody brings you food. They're going to run the exact same operating system You can get iOS tablets. This is an iPad here. They work beautifully, again, but it's a sealed system. And yup, they have their place. One place I like to use a tablet is for my home automation. and instead of trying to get my phone to use it, I have one tablet that's kind of just dedicated to that one particular job. are definitely the two biggies, but I want to make sure we're comfortable In particular, I want to talk about wearable technology. So let's start with this guy right here. This is Mike's smart watch, so this is a little Fitbit, and I like to use this. It's got built-in accelerometers, it's got a heart-rate monitor. And it syncs with my phone and it shows me how much I've been walking and stuff 'cause I could use a little walking, couldn't I? Alright, along with that is going to be something like this. Let's see if we can get this Wahoo in here. for somebody a little bit smaller than me. Well I'm going to make this work now, there we go. And this can actually sync with my phone of my heart rate in an extremely accurate way See these at lots of health clubs. Okay, the other big type of device we see a lot are e-readers. So this is a Kindle Paperwhite. so I can read them. I like it because it uses very little power. You can get a lot of different types of e-readers out there. I like this one because it's just, it doesn't use much electricity. It doesn't have a backlight, it isn't in color, it just works, I love that thing. Okay, let's keep going, we have so many fun things to play with here. Here is another good one. This is a GPS device. I might argue that GPSs are some of the earliest smart devices out there. Obviously, it's a sealed device, it certainly has an operating system, usually some cut-down version of Linux. It stores maps within the GPS itself unlike our phones, and they've been around for quite a bit. It's actually kind of interesting. A lot of these are pretty smart devices in terms of, they'll actually work for things like Google Auto and things like that to allow synchronizing of different types of features like that. You can actually talk to your GPS and dial your phone, fun things like that. What else do we have? Ooh, let's talk about connections. Let's take a look at this guy right here. This is a credit card reader. Credit card readers are really popular. This is for the swipe style. I've got another style here. And this one I could actually slide chip cards into. It's wireless, it works just like that. And these are great for reading credit cards. If you want to be doing some business, this is a great way to go. So the last thing I want to mention is that there is one place where you might be able to provide some expandability to your smart device, and that is through SD or microSD, or sometimes even mini SD cards. Now these cards, which we covered in other episodes add a little bit of memory, or I should actually say storage to your smart devices. Now Apple devices pretty much don't use them. However, you're going to find lots of Android devices and GPSs, and e-readers, and all kinds of other stuff that will use it. It's often a big benefit, and for a lot of people, it's the main reason they're going to go towards an Android device. (casual offbeat music)
