How does your mobile phone work? | ICT #1

– [Presenter] For most of us, a mobile phone is a part of our lives. But I'm sure you're curious minds have always been struck by such questions as how a mobile phone makes a call, and why there are different generations of mobile communications? (upbeat music) Let's explore the technology
behind mobile communications. When you speak on your phone, your voice is picked up by
your phone's microphone. The microphone turns your
voice into a digital signal with the help of MEMS sensor and IC. The digital signal contains your voice in the form of zeros and ones. An antenna inside the phone
receives these zeros and ones and transmits them in the
form of electromagnetic waves. Electromagnetic waves
transmit the zeros and ones by altering the wave characteristics, such as the amplitude, frequency, phase, or combinations of these.

For example, in the case of frequency, zero and one are transmitted by using low and high
frequencies respectively. So, if you could find a way to transmit these electromagnetic waves to your friend's phone, you would be able to establish a call. However, electromagnetic waves are incapable of traveling long distances. They lose their strength
due to the presence of physical objects, electrical equipment, and some environmental factors. In fact, if there were no such issues, even then, electromagnetic waves
would not carry on forever, due to the Earth's curved structure. To overcome these issues,
cell towers were introduced, using the concept of cellular technology. In cellular technology, a geographic area is
divided into hexagonal cells with each cell having its
own tower and frequency slot. Generally, these cell towers
are connected through wires, or more specifically,
optical fiber cables. These optical fiber cables
are laid under the ground or the ocean, to provide national or
international connectivity. The electromagnetic waves
produced by your phone are picked up by the tower in your cell and convert them into high
frequency light pulses. These light pulses are carried
to the base transceiver box, located at the base of the tower for further signal processing, After processing, your
voice signal is routed towards the destination tower.

Upon receiving the pulses, the destination tower radiates it outwards in the form of electromagnetic waves, and your friend's phone
then receives the signal. This signal undergoes a reverse process, and your friend hears your voice. So, it's true that mobile communications are not entirely wireless, they do use a wired medium too. This is how mobile
communications are carried out. However, there was a big issue that we intentionally left unanswered. Mobile communication is only successful when your tower transfers the
signal to your friends tower. But how does your tower know in which cell tower area
your friend is located? Well, for this process,
the cell tower gets help from something called a
mobile switching center. The MSC is the central point
of a group of cell towers. Before moving further, let's explain more
information about the MSC. When you purchase a SIM card, all the subscription information is registered in a specified MSC. This MSC will be your home MSC. The home MSC stores information
such as service plans, your current location,
and your activity status.

If you move outside the
range of your home MSC, the new MSC, which serves you instead, is known as a foreign MSC. As you enter a foreign MSC region, it communicates with your home MSC. In short, your home MSC always knows which MSC area you are in. To understand in which cell
location the subscriber is within the MSE area, the MSC uses a few techniques. One way is to update
the subscriber location after a certain period. When the phone crosses a
predefined number of towers, the location update is again done. The last one of these is
when the phone is turned on. Let's try to understand
all of these procedures with an example. Suppose, Emma wants to call John. When Emma dials John's number, the call request arrives
at Emma's home MSC.

Upon receiving John's number, the request will be
forwarded to John's home MSC. Now, John's MSC checks
for his current MSC. If John is in his home MSC, the call requests will be immediately sent to his current cell location, and it checks whether John
is engaged on another call, or if his mobile is switched off. If everything is positive,
John's phone rings, and the call will be connected. However, if John is not in his home MSC, John's home MSC simply
forwards the call request to the foreign MSC.

The foreign MSC will follow the previously
explained procedure to locate John's phone, and will then establish the call. Now, let's discuss why
the frequency spectrum is quite important in
mobile phone communications. To transfer zeros and ones
in digital communication, each subscriber is
allocated a frequency range. However, the frequency spectrum available for cellular communications
is quite limited, and there are billions of subscribers. This issue is solved with
the help of two technologies, one frequency slot distribution, and two, multiple access technique. In the first technique, different frequency slots
are carefully allocated to different cell towers. In the multiple access technique, this frequency slot is
efficiently distributed amongst all the active
users in the cell area. Now, the big question. Why are there different generations of mobile phone technologies? 1G originally allowed
users, for the first time, to carry a phone without
a cable attached to it. But 1G suffered from two major problems. The first problem was that
the wireless transmission was in an analog format. Analog signals that are easily
altered by external sources. So, it provided poor voice
quality and poor security.

The second problem was that it used the frequency division
multiple access technique, which used the available
spectrum in an inefficient way. These factors paved the way
for the second generation of mobile communications, 2G used digital multiple access
technologies, namely TDMA, or CDMA technology. The second generation also introduced a revolutionary
data service, SMS, and internet browsing. 3G technology was focused on giving a higher data transfer speed. It used a WCD multiple access technique, along with an increase in bandwidth. To achieve this, the 3G speed of two Mbps allowed the transfer of data for uses such as GPS, videos,
voice calls, et cetera.

3G was a huge step in the transformation of the basic phone to a smartphone. Next came 4G, which achieved
speeds of 20 to 100 Mbps. This was suitable for high
resolution movies and television. This higher speed was made possible due to the OFD multiple access technology, and MIMO technology. MIMO uses multiple
transmitter receiver antennas inside both the mobile
phone and the towers. The next generation of
mobile communication, 5G, to be rolled out soon, will use enhanced MIMO
technology and millimeter waves. It will provide seamless connectivity to support the internet of things, such as driverless cars and smart homes. Would you like to learn

SAMSUNG’S FIRST TRANSPARENT PHONE | TRANSPARENT MOBILE PHONE

once in a while you hear about transparent smartphones although various smartphone manufacturers have been developing this advanced technology for decades there are as yet no devices available that are fully transparent samsung looks busy with the development of a transparent display device which i will tell you in detail but if you are new here and want to stay up to date about the latest tech reviews and news please hit the subscribe followed by the bell in january 2020 samsung electronics filed a utility patent with the united states patent and trademark office the patent was published on august 27 2020 and describes the technology needed to create a transparent smartphone alternatively the technology could also be applicable to other consumer electronics products such as a tv monitor laptop and game console as a basis an oled display is used which is characterized by low power consumption high brightness and a faster response time than conventional lcd displays the oled screen is equipped with a transparent luminous display panel through which light can shine thus content can be displayed on the transparent screen while users can simultaneously see through the phone it can be a flat display but also a flexible screen that can bend fold and a roll according to the patent description it is a technically defined patent that goes into great detail about the different layers and components required to achieve transparency the patent images show a modern smartphone with narrow bezels and the large transparent screen each pixel on the phone's display would allow light to pass through it effectively rendering the screen transparent in samsung's patent drawings that transparent screen resembles a window through which the holder's hand can be seen only the bezels seem to be opaque dreams of transparent phones aren't new lg had a crack in 2009 with the gd 900 but it only featured a transparent keypad sony ericsson followed up with the xperia pureness which to its credit did feature a transparent display it wasn't very good though the company would need to find a way of housing the battery and other components so as to not interfere with the transparent display or somehow make those elements transparent too it's a problem that was demonstrated by taiwanese firm polytron technologies transparent phone in 2013.

the sd card and ribbon cables were still visible despite the phone's largely transparent body these patents rarely develop into mainstream devices so don't expect samsung to launch a transparent galaxy s or note series shortly but the search for the next big smartphone innovation is taking companies to extreme if not impractical lengths that's the end of this video let us know your thoughts in the comment section below i will see you in my next video you.

Testing a phasing SSB receiver: Part 1 – with a mobile phone

my latest project is this simple receiver for 80 meters its direct conversion unlike others it is actually a phasing receiver so it can cancel the opposite side band providing single signal reception it's based on a design by SP 5a HT although his rigorous for a transceiver I finally made this one a receiver in this video I'll be using some simple test equipment to see how good the image rejection really is first of all a quick look at the receiver under test it's very simple just three transistors and one IC yet it's a phasing SSB receiver for 80 meters the local oscillator is in the left half of the case it uses to be c5 for a transistors it's free running one transistor is the oscillator and the other is a buffer that output signal feeds into the balance mixer which I'll talk to about in more detail in a minute the incoming signal comes from the antenna socket via an RF gain control and that also acts as the volume control you don't need two of them in a simple receiver and then into an RF preamp from the output of the RF preamp the signal goes into an RF phase shift network just a capacitor and a trimmer resistor that splits the signal into two and feeds it into the diode balance mixer mixing it with a local oscillator signal from the vfo the male audio signal goes to an audio phase shift network comprising of a few capacitors and resistors that's combined and is then fed to an LM 36 audio amplifier so it's a very simple receiver to transistors in the vfo one transistor in the RF preamp and an lm386 IC in the audio amplifier yet it's a single signal receiver with opposite sideband rejection and is strong enough to drive a speaker on most signals our first piece of test equipment is an RF signal generator it's actually a DDS vfo a kit by in freeze ed I you can see here the main vfo board and the display board but there's extra room in the box for a few hour of things the kit was a joy to build and worked first time so I'd highly recommend it the other item of test equipment is actually a mobile phone app this one is called frequency and is available for Android phones it's free and you can download it and it effectively gives you an audio spectrum analyzer now turning 80 meters we have wiles of the right here is a 7600 we're now going to run a series of tests first of all internal noise the receiver is off the gain is set to full and I'll turn the receiver on that's the receiver long that's the receiver off so the receiver has very little internal noise next thing we'll do we'll connect the antenna just watch what happens on the phone now the noise has gone up to minus 60 on the display so there's clearly adequate sensitivity to my noise level which admittedly here is quite high it's 200 Hertz that's minus 32 that's gone up to 300 Hertz and it's about minus 22 so there's a big change there which is which is good which is about how you want it it's been more at 400 Hertz it's pretty much level much level where – 20 dB but from Circular here top it drops dramatically which again is is about what you want hi there it's not quite smooth looks like we've got a bit of a double hump there because it's quite quiet 4 kilohertz and very high at 5 kilohertz so it's a bit of a hump around two and a half kilohertz but it really drops off about 60 kilohertz you can still hear it around 7:00 to 10:00 so it's quite clearly need some improved audio filtering above about three or four kilohertz because we really shouldn't be hearing audio and that sort of level you can hear very clearly the difference in the signal the strongest signal you heard was in the correct lower side then whereas this receiver is set up to reject the upper sideband and it was significantly weaker the receiver is set up to 3.5 stories zero megahertz sir as the n3 said I DVS hence nothing is audible from a receiver as we are exactly zero beat the signal generator now is 3 for 99.5 so it's a 500 Hertz time and it's rating around 22 DB minus 22 DB on the phone that's our reference we're now we've now gone up one kilohertz 35.5 and that's about – 32 DB so that's around 10 DB rejection there's a trim pot in the RF phase shift network and if we adjust it see what effects it has on the opposite on the image and it dramatically drops the volume of the image we're on three four 99.5 350.50 round 20 DB of image suppression be at 500 Hertz three point four nine nine 5501 and it's reading the tucked under – 40 so again that's a 20 DB suppression almost just adjust the raising pot now look at that that is spectacular about 30 DB of image rejection at one kilohertz which is pretty good for something so simple but of course one of the costs of a simple phase shift network is that the image rejection varies across the frequency range so we'll try another frequency like 2 kilohertz three four nine eight long city P 502 it's minus 50 I haven't adjusted anything and we're 20 DB down or just is more twittering and it's down there nearly at minus 60 back to the lower sideband it's minus 30 so again at 30 DB rejection I did have to toodle the phasing control so it's not quite uniform across the whole audio frequency range okay so it's not quite single signal reception but even a very simple phasing receiver can rejects and wondered signals by maybe 20 or 30 decibels it's not great for the competitive DXi but for the casual listener it is a big improvement over a simple direct conversion receiver that gets no image rejection at all I'm suggest looking on the web for we many transceiver projects by sp5 a HT it's an incredibly simple phasing 80 meter SSB transceiver and this receiver is really a simplified version of that there are some performance compromises but it's still a pleasure to use and in the trade-off between simplicity and performance I think it scores pretty well

Surface Duo first look: Microsoft’s foldable Android phone

– Remember Windows Phone
from way back when? Well Microsoft is kind
of getting back into making smartphones. This is Surface Duo, and it runs Android. Not Windows or Windows Phone. That's right. Microsoft is making a
Surface phone with Android. If that sounds surprising, it's because it really is. But we'll get back into the Android side in a minute. Duo is part of two new futuristic dual-screen devices that
Microsoft announced today. And they're coming in Holiday 2020. Surface Duo has two 5.6 inch displays that fold out into an
8.3 inch device overall. And it's just 4.8 millimeters thin. It folds like many two-in-one laptops thanks to a 360 degrees hinge. And it's designed to
get more done on the go. It looks tiny for this type of device, and it felt kind of like a Galaxy Note in my pocket. Now, I wasn't allowed to play around with the software on this device, but it looks and feels
like a tiny pocket tablet that's also a phone. The difference between this and any other Android phone, except maybe the Galaxy Fold, is visually obvious.

But Microsoft thinks this is part of a new category of devices that allow people to do a lot more with tablets and phones
than they do today. As part of this idea, Microsoft also announced a
Surface Neo device today. Which has two larger 9 inch displays. The Duo and the Neo share a very similar design, but they don't share a
common operating system. Neo, the larger dual-screen device, runs Windows 10 X, and has all your familiar
desktop and tablet apps. The reason this isn't
running Windows Phone is because Microsoft gave up on that operating system years ago, when it couldn't convince developers to create apps for it's devices. Now we sat down with Microsoft's Chief Product Officer, Panos Panay, on the Vergecast this week, to talk about why Microsoft
chose Android this time for the Surface Duo.

– [Panay] Well because, those are the apps you want. I don't know how to answer it differently for you. Because there's hundreds
of thousands of apps and you want them. Asati and I talked about it, it's about meeting our
customers where they are. And I don't think the, you know, the mobile application platform's going anywhere any time soon, you need the apps. – So you'll get the apps you'd expect from a phone inside
the dual-screen device, but how is this different from any other smartphone? I mean it obviously looks different. And the main idea is making use of these two displays in ways we're only starting to see other Android phone makers explore. You could run a game on one side, and a game pad on the other, or multi-task by dragging
and dropping content between apps. Microsoft hasn't thought
of everything you'd do with the Surface Duo just yet, but that's why it's announcing it now so developers can fill in the gaps.

They're really aiming to introduce a new form factor here, and a way for a device to
adjust itself on the go, no matter the task. We've seen foldable devices from Huawei and Samsung, but the Duo has two separate displays that are made of glass, rather than foldable plastic. Which given the issues
with Samsung's Galaxy Fold, that might be a good choice right now. Microsoft has been
working on this hardware for three years, and Panos Panay tells us that this device won't change much by the time it debuts late next year.

The real key question will be whether Android app developers create the apps and
experiences that really take advantage of this dual-screen device. And whether consumers
want this type of hardware in a phone form factor in the first place. That's why Microsoft also has its largest Surface Neo device running Windows. And it really feels like the company wants to offer a Surface at every shape and size. Microsoft also seems to be implying that the operating system really doesn't matter for
Surface devices anymore.

And it's willing to partner
with Google and others to offer what makes sense. So does that means that
Android is the future for Microsoft? – [Panay] (clears throat)
No no no no no no. You want to give customers what they want in the form factor that they're using. We've learned this, you know, the right operating system
on the wrong product or the other way around, pick your words, but what's the right operating system for the form factor? And in this case, in mobile devices, Android's
the obvious choice. But anything above that, Windows is everything.

Superior for me. – So, will the Surface
Duo and the Surface Neo combine in the future? Will there be a smartphone
that turns into a tablet, that then turns into a laptop, then you dock and turns into a real PC? We're years away from anything even getting close to that. But it opens up the questions about where this dual-screen and foldable hardware is going exactly. And they're really hard
questions to answer right now. Microsoft will now need to convince app developers and consumers that these dual-screen devices are truly the new device category that we've
all been waiting for.

Wherever things end up, it looks like Microsoft want to be ready at every point with Surface. You want a phone that's a little bit more than a phone that
has an extra display? Surface Duo. You want a tablet that
transforms into a laptop? Surface Neo or Surface Pro. Microsoft is covering
every hardware base here, and it's leaving it up to you to decide what device you actually need.

– [Panay] You know, I think like anything, look at the product you think is most interesting to you and where you think you can be more creative, that's what I would push. And I think this products gonna be there next year. Not in a hurry, you know, hang out. Take photos or do whatever it is you do on your phone today
for a little bit longer and then, see if we can convince you that you can be more
creative on this product. – It's been a crazy day of Surface devices and there's a bunch of hands-on videos you should check out
on our YouTube channel.

Be sure to also definitely
check out the Vergecast, 'cause it has the full
interview with Panos Panay, and you don't wanna miss it..

HTC Magic Mobile Phone – Part 1 – Unboxing & Review

this is the HTC magic I purchased this from a company called shx Limited on eBay and I paid just under 290 pounds for an unlocked HTC magic now although this is vodafone branded they all come unlocked so you can put any SIM card inside one of these handsets now apart from the handset itself you also get we just cut the Box open a really nice little pouch which I'll show you a little bit closer in a minute we also get a warranty statement Quick Start Guide which introduces you to the handset and the user interface also get a UK charger three-pin plug on this end and then on this end a USB connector I also get a hands-free kit it's not a three-and-a-half millimeter audio jack on this end though sir proprietary USB mini USB connection HTC developed so it's a slightly different shape to normal mini USB connector so if you want to use normal earphones or headsets then you're either going to have to buy an adapter or stick with a bluetooth headset you also get a standard USB cable in the box as well so you can charge the handset with your computer or a USB charger or you can use this for connecting the device to your computer for transferring files across as well so now let's take a look at the HTC magic itself now before I move on to shown you the handset in great detail just want to pop back to this little pouch it's a nice soft finish pouch and I just want to show you that it's a really nice fit for the handset now back to the HTC magic it's a very sleek device on this side here all we've got is a rocker switch for the volume controls this is nice slimline switch integrated into the side of the handset the front is the gorgeous 3.2 inch screen which runs a 320 by 480 resolution we also got some extra controls on the bottom of the handset here we have a home button which takes you back to the main home screen menu button which gives you various access to different options depending what application you're using we've got a call start and a call end button the call end button also doubles up as the power on/off button we've also got a back button a search button there and also a trackball which you can also push in acts as an enter button as well this side of the handset is completely clear as is the top and then the bottom just sports that USB connector and the microphone around the back of the handset we have lanyard connector here and we also have the 3.2 megapixel camera so open you just slide down the back and then if I show you under here we've got the 13 hundred and 40 milli amp hour battery which in my test so far has been performing very well indeed is giving me two good days of use between charges in this slot here you can put a micro SD or SDHC memory card the shx deal that I purchased comes with a 2 gigabyte card which is great for getting you started you can add up to 16 gigabytes through that slot there it's also worth mentioning that the HTC magic is quoted on the HTC website for the European version as having 512 megabytes of ROM storage and 192 megabytes of RAM well when I go into my settings here and have a look at the memory usage on the phone it's actually reporting that I've got two hundred and forty three megabytes available so this may well be the 288 megabyte ram version that's available for the rest of the world now don't quote me on that but certainly as far as I can see this could be that 288 megabyte ram version now this HTC magic runs the Android operating system for mobile phones and this is running version 1.5 which is also known as cupcake now what cupcake gives you is three home screens which you can customize as you wish to customize one of the screens we've got a lot of blank space here which is touch and hold and then you get a choice of adding shortcuts widgets folders or wallpapers if I choose widgets then for example I could choose to add a search widget which I can then hold and drag into a new position if I decide that I no longer want this widget then I can drag it into the bin at the bottom of the screen so this allows you to customize your phone as you wish and it makes it very useful to be able to do this because you can put shortcuts to all of your favorite applications on your home screen there things run very smoothly they launch very quickly as well and it really is a joy to use it's loaded with features you've got that 3.2 inch screen you've got the 3.2 megapixel camera on the back you also got Wi-Fi and Bluetooth as well and don't forget this GPS built into this handset so look out for my future review of copilot life the sat-nav application running on this HTC magic believe me it runs very nicely so rather than the contract from Vodafone I've got this unlock from SH X and it works perfectly with the O's whose SIM card there was a few settings to change for the APN settings to allow me to access Internet wife's out and about but certainly it's proving to be a very nice phone it comes highly recommended and the Android Marketplace really does make the phone deliver certainly a very similar user experience to the iPhone I should also really be showing you this notification bar at the top now as well as the normal symbols you get on a mobile phone for just run across these at the moment we've got Wi-Fi signal we've also got the fact that I'm in silent mode my mobile network signal strength battery left and also the current time we've also got notifications over here and this acts like a draw that you actually pull down and it tells you I've got one new unread email and I can click into that and go into my email application to get rid of the draw I simply slide it back out of the way it works in a very similar way to the drawer at the bottom which I can put up to reveal all of the icons for my various applications if I scroll down here I can for example go into my shop savvy application and this particular application which I will cover in a separate review allows me to scan in products with the barcode reader and search for better prices to buy the product either locally or online so everything works as I would expect it gives me a viable alternative to the Apple iPhone and for two hundred and 89 pounds or just under that 300-pound mark I'm getting a very nice handset it feels nice to hold it performs very well it's got the same 528 megahertz processor as you'll find in HTC's latest hands at the hero in a slightly different package well thanks very much for listening come back soon and check out more reviews on geek androids Co dot uk' this video review is sponsored by easy draw

Quest 2 Casting to your TV or Phone | Oculus

(upbeat music) – This video is going to show you how you can bring spectators
in on the action, in seconds. (shouting) It's called casting, and it let's you take what you're seeing on your headset and put it on a phone or a compatible TV. And it's easy, like "two
buttons and you're done" easy. All you need is your
headset, the Oculus app on a mobile phone, and
for the best experience, a TV equipped with a
compatible casting device. Yours might have one already built in. First step, it to make sure
your Oculus app is ready. So make sure you have your headset and your mobile phone on
the same wireless network. And there are two ways to begin casting: From the headset or from the app. Let's see how to do it from
the player's perspective.

From the Home menu, click Sharing, select Casting and then choose where you want to send your footage: To a phone or a TV. From the Oculus app, simply
click the Casting button in the top right corner,
and choose your destination. Then, you'll get a confirmation message in your headset – you ready? – Yeah. – [Man] Check this out. – Yeah! – Oh hold up, quarter shot! He's spiking! So that's it, you just made
virtual reality social.

See you in VR..
