An article about the principle of operation and concept of GPRS and GPS systems, and their use in cellular communications/

Navigation

Cellular telephone, this is a mini radio transmitting and receiving station that provides full radio communication without interference. A cell phone is a center of Internet technology that provides systematic access to the World Wide Web.

Mobile phone - mini - radio station

GPS technology used in mobile communications, this is a network of global determination of an object with location reference, using space satellites, carrying out digital data transmission.

Military object identification technologies used in the GPS system

The GPRS system is a technology that allows a cellular subscriber to exchange messages and calls with subscribers of other devices over this network, external networks and the Internet.

Using the GPRS system for civilian objects

Transceiver channel of the system

A cellular subscriber has its own channel, consisting of a modem in mobile device. The GPRS system has its own communication channel. Configuring both channels relative to each other makes it possible to exchange and transmit data.

Mobile phone communication channel, modem

Data transfer takes place in the service mode of the telecom operator to which the subscriber belongs.

System capabilities

• instant internet access
• ability to connect gadgets to the Internet: smartphones, tablets, laptops
• tariffs based on actual Internet access, namely, based on the volume of information sent or received

GPRS system capabilities

Connecting the system on a personal phone

Several ways:

• connection in “default” mode from your phone operator
• manual connection
• connection via mobile operator service by phone
• connection through the operator’s communication salon

Connection in the “default” mode from the operator does not require solving problems or any actions for the subscriber.
Manual connection is required for phones where manufacturers have not taken into account automatic system configuration. Connecting through the service of a cellular operator involves calling a specific number of this operator. Information about the phone number can be found on the operator’s website, contact a service center representative there, and receive a package of settings from him automatically, sent to your phone. If the procedure does not work, you can manually configure the system at the prompting of a service center specialist.

Methods for connecting the GPRS system to a mobile phone

Phone numbers of operator service centers for connecting the system

• MTS - call the number 0876 or any text message to the number 1234
• Megafon - call a number 0500 or text message (digit 1 ) to the number 5049
• Beeline - call by number 0880 , saving sent settings when using a password "1234"
• Tele 2 - call the number 679

All operators except MegaFon provide the opportunity to order GPRS settings via Personal Area on the operator's website. To do this, fill in information about the phone model, operating system, and your number, in the order - online. A telephone in which there are several cards, a package of settings is sent to each card. The last way to connect is GPRS, contact a communication shop for help.

Difference between GPS and GPRS

GPS is a satellite communication system for determining coordinates, location on the map, speed of movement, and an object. The owner and operating organization is the American Department of Defense. The system is available to ordinary subscribers if they have a navigation device or a mobile phone with a GPS receiving device.

GPRS is an internal GPS system, a transmitter that sends data to cellular subscribers, connecting them with gadgets to the Internet and other devices.

The difference is that GPS is for identifying an object, GPRS is a radio data transmission system when connected to the Internet.

Collaboration of two systems GPRS and GPS

GPS refers to military technologies, GPRS has nothing to do with the militaristic sense of identifying objects and the parameters of their location.

The meaning and principle of operation of individual systems is significantly different. However, their tandem provides enormous opportunities for the civilian cellular subscriber.

Video: Setting up GPRS

We'll tell you what GPRS is and whether modern smartphones need it.

Majority mobile phones supports Internet connection. Typically, services are used for this mobile operators, which offer users several network connection options:

• GPRS.
• 3G().

Let's focus on the first option. The GPRS standard is a general packet radio service. Essentially, this is an add-on that is present in older devices. But new smartphones also support GPRS communication.

To use GPRS, you need to set the correct access point settings provided by your mobile operator. Usually this information is located on the company’s official website. The potential user needs to enter the phone settings, save the necessary configuration and open the browser to use the Internet. Once the connection is successful, a “G” symbol will be displayed on the screen.

The GPRS standard is usually characterized by low speed. The technology allows you to achieve a maximum data transfer rate of 172 kilobits/s. Practice shows that this value is overestimated. A decrease in speed occurs as a result of the congestion of the mobile operator and various obstacles between the smartphone user and the cellular repeater.

Why do you need GPRS in a smartphone?

A logical question may arise - why use GPRS if modern phones support modern communication standards? The main reason is poor coverage of the cellular operator. To access the Internet in a rural area, you can only connect to an outdated communication standard. Other methods of transmitting information often remain ineffective.

The second advantage of the standard is low energy consumption. It is relevant for users of navigation programs. 3G or 4G communication quickly drains the smartphone battery, as it requires increased energy for the radio module for transmitting information. The outdated protocol will significantly extend the use of the built-in battery. This feature is useful if the smartphone is often used on trips as a navigator.

The third reason for enabling GPRS is the low cost of services. Sometimes you need to use a certain website or read news on the Internet. It will be impractical to connect a 3G or 4G Internet package - such a service is very expensive. It is much more profitable to use a GPRS connection and save money on your balance. Of course, in 2019 this argument seems impractical.

GPRS technology remains relevant in 2019. Thanks to the standard, phone owners can visit the required website or use a navigator to transfer the coordinates of their location to another device. But there is a serious drawback - extremely low Internet speed.

What is GPRS

Beginner users often confuse GPS and GPRS. Sometimes they also confuse the first two terms with RFID, but for this, you definitely need to deprive yourself of sweets. To avoid confusion, let us clarify this issue. Today we will find out what the mysterious term GPRS means, which in common parlance is pronounced as “ZhPRS”, and in very common parlance... however, I won’t be able to say it on the radio, because I’ll be fired right away. So, the abbreviation GPRS stands for and translates as “packet data transmission over a radio channel”. GPRS is like an add-on over GSM standard, on which our usual mobile phones work. To implement GPRS, the mobile operator requires installation, configuration and ongoing administration of various hardware and software, which together forms a special computer-mobile network. However, ordinary users should not worry about all these subtleties. To use this technology, they just need to buy a GPRS-enabled mobile phone, and I should note that almost all modern phones, even the cheapest ones, support it. After this, you need to enable the GPRS service from your operator, if it is suddenly not turned on, and then use GPRS in the tail and in the mane, if there is such a need. What does GPRS provide on a regular mobile phone/smartphone? The ability to access the Internet and connect to relevant services: Internet pages, news channels, and so on and so forth. “Wait,” you say. “What about WAP? I remember that I can connect to some pages from my phone using WAP.” That's right, you can! But only when you connect to WAP via a regular connection (CSD), then your phone is busy, and you pay for this connection almost the same as for a regular conversation on a mobile phone - that is, wild money! And GPRS is a technology that allows you to transfer data over parallel channels that practically do not interfere with normal communications. In this regard, you do not pay for the time you work on the Internet, which is very painful for any wallet, but only for traffic - that is, for transferred files (I note, just in case, that opening some Internet page already means downloading files - text and page design). Moreover, this fee, compared to payment for calls, is very small: approximately 10-20 cents per megabyte of data. Thus, your mobile phone can be connected to GPRS constantly - this practically does not interfere with incoming and outgoing calls, and if you do not download anything, then no money is spent from your account.

Hi all. Guys, today we have a very interesting topic, namely GPRS, what is it on the phone? Eh, guys, if only you knew how much time I spent in the past studying GPRS, in the past, I mean in the distant past... You can even say that about eight years ago, so long ago all this happened =) The phones were mostly push-button, no touch screens, everything was different, although there was Internet, it was slow and expensive.. nostalgia...

So, about GPRS. What is it? This is a data transmission standard; roughly speaking, GPRS is mobile Internet. And yes, it’s slow, that is, there’s no Wi-Fi here, it’s impossible to download a movie on such an Internet, or at least it’s possible, but it will take a long time.. a lot.

Guys, here I would write, so to speak, introductory and superficial information about GPRS, that is, without delving into the jungle, but at the same time I tried to talk about basic things.

Picture on topic:

GPRS Internet comes from the SIM card, and then the operator provides it, well, very figuratively speaking. Modern phones can already squeeze everything out of GPRS, although all the same, its maximum speed remains low, but it’s suitable for social networks (with a stretch). True, although modern phones support GPRS, mostly the Internet already uses 3G, or even 4G technology, but where these technologies are not available, well, I mean remote places from the city, then GPRS can be useful there =)

Well, do you understand what GPRS is? This is the type of Internet that is used today in smartphones and the Internet itself only works thanks to a SIM card. Wi-Fi, of course, also allows you to have the Internet, but this is completely different. But as I already wrote, phones usually use 3G Internet, and where it doesn’t catch, you have to deal with GPRS.

There is also something called EDGE, it’s kind of like GPRS, but faster, but still far from 3G.

GPRS stands for General Packet Radio Service, this is a type of public packet radio communication.

So, okay, now I think it would be better if I answer the most common questions about GPRS, so to speak, okay? So, let's go.

1. How to disable GPRS on your phone? To disable it, you just need to not use it. If you are losing money on your phone because of the Internet, and at the same time you have a smartphone, and not some kind of phone, then most likely some application is accessing the Internet. I don’t know if there is even an option to turn off the Internet in a modern smartphone, but I know something else, you can change the Internet settings. That is, those settings that the operator sent you, change the APN access point there, and something else. All this can be changed somehow, as long as it is wrong and as a result the Internet will not work. You need to look in the settings for something like Internet profiles. If something happens, then it’s easy to set it back up, you just order automatic settings and that’s all, but you don’t have to delete the old, incorrect ones, but leave them just for the purpose of shutting down the Internet, so to speak. There should be an option in the smart phone to switch between these settings.
2. How much does GPRS cost? This means that GPRS is charged not by time, but by megabytes. One megabyte costs a decent amount, I can’t say for sure, I don’t know anymore, but it’s generally expensive. But now there are all sorts of tariffs, Internet packages, each operator has their own, you need to find out. There is also such a service as unlimited Internet for a day, but again, if the phone and operator support 3G, then the Internet will be fast. And if the phone does not receive 3G, then the Internet will use GPRS technology. But I’ll say right away that GPRS is still not suitable for watching a movie online, downloading something, or listening to music online, you should forget about it. No, in principle, some things are possible, but it will all take a long time and you will quickly get bored, and the speed may be quite unstable. Social media, all sorts of instant messengers, Skype and Viber (text only), that's all, yes, it can all work somehow. Regarding Skype, by the way, I once tried to call via the GPRS Internet, but then I used this Internet on a computer, so just think, Skype worked, sometimes it stuttered, of course, but it worked. How it is now, I don’t know =)
3. What is the speed of GPRS? This means the maximum speed, well, in general, what is possible under the best conditions and if the stars shine correctly, then this is 171.2 kbit/s. But as you understand, in practice it is less. But 171.2 kb/s is only a speed, and you can download at a maximum speed of 21.4 kb/s, because 171.2/8 = 21.4, that’s the arithmetic =) After all, the speed is in kilobits, but the download is in kilobytes, and in 1 kilobyte - 8 kilobits, what a joke. Do you want another joke? Let's take a song in MP3 format, let it weigh 5 megabytes. There are 1024 kilobytes in 1 megabyte. The maximum GPRS speed is, as we have already found out, 21.4 kb/s, so now think about whether it will download quickly or not….
4. What is the speed of EDGE? Well, here the speed is already higher, the maximum possible is 474 kbit/s, and also, as you understand, this is under the most ideal conditions. Well, the speed with which you will download is 474/8 = 59.25 kb/s, which is of course better, but it is unlikely to be the same, but if it’s half as much, that’s also not bad and the sites are still not very fast, but will open.
5. What about 3G, what is the speed? The maximum speed under super conditions is 3.6 Mbit/s, which is already quite good. In fact, it’s less, understandably, but still not bad, and the film can already be watched in average quality, I mean online. There is also something like 3G+, this is some kind of advanced 3G, I don’t know, but the speed there is impressive, the maximum can be 63.3 Mbit/s, guys, I can’t even believe that it can have such a speed mobile internet.
6. How to use GPRS Internet on a computer? So again, guys, everyone’s smartphones are different, but in general, the scheme is like this. You set up the Internet on your phone and check that it works. Hmm, I don’t know how it is now, I’m a little behind technology. But there are two options. You can create a Wi-Fi access point on your phone and then connect to it from your computer. The second option is to connect your phone with a USB cable to your computer and use the phone itself as a modem. A connection is created on the computer, everything is simple, but nevertheless you need to know how, by the way, operator support can help with this. So, you create a connection and then the Internet will work through the phone, the phone itself will act as a modem. If I'm not mistaken, you can still make phone calls, and the Internet will still work on your computer. But it wasn’t like this before, well, when there were still push-button telephones, with incoming call the internet was interrupted.
7. What is the difference between GPRS and GPS? Guys, the question is not very correct. GPRS is data transfer, in short the Internet. GPS is navigation using maps, it works without the Internet, the phone has a built-in GPS module that exchanges data with satellites and, in short, finds out where you are and shows it to you on the map.
8. What is the difference between GPRS and GSM? Well, again, GPRS is the Internet, while GSM is a completely different story... GSM is a standard for digital mobile communications. While GPRS is something that works over GSM.
9. What is the difference between GPRS and Wi-Fi? Look, GPRS is the Internet from an operator, which can be in any modern phone, but the main thing is that the Internet goes, so to speak, along the same path as calls, well, roughly speaking, it’s all GSM. Wi-Fi is completely different, if the phone has Wi-Fi, this means that the phone can simply connect to any network and take the Internet from there. Networks may or may not have a password. For example, there seems to be Wi-Fi in the metro now, well, there is definitely somewhere. Internet via Wi-Fi has nothing to do with the operator, that is, you can access it even without a SIM card, if your phone supports it. And money for Wi-Fi will never be withdrawn, it’s kind of technically unrealistic.
10. What is the difference between GPRS and 3G? So, well, I already wrote, it’s all about speed. And it’s probably also that not all old phones support 3G, and 3G itself is not available everywhere, where GPRS is available.
11. What's the difference between GPRS and WAP? Oh guys, WAP is actually an ancient nightmare. In short, firstly, it’s slow, and secondly, not all sites work there at all, I don’t even remember how it is or what.. WAP is what was before GPRS, what supported even the oldest ancient phones without a color screen . That is, the Internet on a phone that does not have a color screen, it generally seems unrealistic. But then the Internet is in quotes... in general, there is also WAP 2.0, but still this is not a full-fledged Internet. In general, if I'm not mistaken, WAP (Wireless Application Protocol) works via CSD (Circuit Switched Data). But what is CSD? CSD is like GPRS, but it just appeared earlier and works about the same, but is available even on non-color phones. I’m generally silent about the speed, it’s like 9.6 kbit/s, which is terrible. Because of this speed, there had to be special pages in order to load at least somehow. And on black and white phones there were no pages at all, so what to show there, the text was just loading there. In principle, it’s normal, but I didn’t see the point in this in such an Internet, it’s easier not to use it. Although it was possible to check the weather, I also remember that back then the Internet seemed to be charged per minute... and it was not cheap.
12. Can GPRS be different? Yes, maybe I don’t know how things are now, but I think that in all modern phones GPRS is already maximal, so to speak. In general, there is such a thing as a GPRS class; earlier, in the era of push-button phones, each phone had its own class. Therefore, for example, GPRS worked faster in one phone, slower in another. The phone may have Class 2, Class 4, Class 6 and so on. The best, that is, the fastest, is Class 12, if I'm not mistaken. But again, this all applies to older phones without a touch screen. And today, I think that all these sensors, all of them have the last GPRS class, that is, 12. These classes also apply to EDGE.

Guys, this is Nokia phone 3220 (color screen, 2004) and this is actually what the WAP 2.0 Internet looked like:

But anyway, I’ll tell you a secret... that many people dreamed of surfing this Internet...

In general, guys, somehow I think we figured out what GPRS is. I hope especially technical information I didn't bother you here. For me, there is only one plus in GPRS, it really catches in many places, where there is no Internet at all and cannot be, where there is not even a telephone line, where the tower is far away, GPRS can catch there. Yes, it will be slow, but I had such extreme conditions and GPRS saved me in those conditions, because the Internet was very necessary, and only GPRS was available there, in general it was a remote village, to put it mildly, far from civilization... That's all guys , good luck to you, I hope I could help you with information, good luck and be happy!

In this article we will give a brief introduction to gprs technology. Let's consider the technical subtleties in the functioning of this gprs technology.

The development of mobile and radio communication technologies has led to the possibility of transmitting data packets via wireless communication interfaces. One of the most popular technologies in this sector is gprs.

Definition

The abbreviation gprs translated into Russian means “general packet radio communications”. Already from the phrase itself, the main features of this interface become clear. These include:

1. Gprs is a radio communication channel. It functions on top existing networks mobile communications in the GSM format, which determines the possibility of using gprs within the coverage areas of mobile telecom operators. Modern trends in the development of mobile communication technologies make it possible not only to increase the speed of information transfer, but also to expand the number of communication channels. The result is not only an increase in the number of available communication channels, but also a reduction in the specific load on each channel.
2. This technology is batch, not streaming. Because of this, there may be a slight decrease in data transfer speed, but the reliability of information transfer increases.
3. Channels are used to transmit data mobile networks. In most cases, currently free mobile voice channels are used as the gprs channel. This step, on the one hand, allows you to use the GSM network as efficiently as possible, but on the other hand, it is a possible reason for the reduction in data transfer speed when mobile networks are highly congested.

Operating principle

For the successful operation of the gprs network, the use of two structural elements is necessary. The first is called BSS, which in Russian sounds like a network of base stations. At this stage, a certain network of available repeaters is formed. After this, a second structure is superimposed on top of this mesh, which sounds like a gprs core. This level is already actually an information transfer interface.

Information is transmitted in two directions: reception to the end device and transmission from it to the network. The final transmission speed depends on the number of currently available free channels and the capabilities of the device to process these channels. Most modern phones and smartphones have the ability to use up to 4 channels for receiving information and up to two for sending. Newer models use an updated interface that expands these capabilities to up to 5 simultaneous channels.

There is a classification of mobile phones based on their capabilities in working with the gprs channel.

1. Class A implies the possibility of simultaneous operation of voice communication and transmission of information packets. This implies the possibility of parallel operation of the telephone for conversation and information transfer.
2. Class B characterizes the possibility of single-channel operation. This means that it is impossible to use gprs and voice communication at the same time. It should be taken into account that in all mobile communication systems more high priority has voice communication. If a voice call or message is received while transmitting or receiving data via gprs, the communication channel is interrupted.
3. Class C are actually gprs communication devices. They are not capable of using voice channels and can only receive/transmit data.

Areas of use

In terms of its operating principle, the gprs network is very close to the Internet. Information intended to be sent or received is divided into small packets and exchanged between devices at the level of these packets. The lion's share of mobile telecom operators use grps specifically to provide mobile Internet services. But there are a number of other possibilities for using the capabilities of this interface. Particular convenience for using gpsr as an Internet channel is added by the possibility of its full integration with almost any common packet data protocols (TCP/IP, X.25).

• Remote mobile access to corporate resources. Many large companies practice using the gprs network to create secure wireless networks access to resources and databases. The advantage of this approach is the high reliability of this network and protection from unauthorized access.
• Satellite monitoring of transport movement. Small packet sizes make it possible to use the gprs network to transmit data about the location of vehicles. These technologies are used to track the movement of public urban transport.
• Creation of telemetry systems. The capabilities of telemetry systems require periodic transmission of small packets of information. For these systems, the use of gprs networks is one of the most optimal options. An example of the use of this protocol as a telemetry system is a system for monitoring temperature indicators and tracking the parameters of animals by placing transmitting sensors on them.

Conclusion

This data transmission technology has its advantages and disadvantages. High security and reliability are often associated with a drop in transmission speed when the network load is high.
