  • What is 5G, and how this technology will change our lives


    DeZire

    Find out what will give users a new generation of mobile communication and whether it is worth buying smartphones with 5g support right now.

    What is 5G?

    5G (fifth generation) - is the abbreviated name of the fifth generation of mobile communications, which will replace the existing 3G and 4G. Behind this reduction lies a whole set of technologies, many of which are still under development. Completion of the testing phase and approval of standards is expected not earlier than 2020.

    What are the main differences between 5G and existing standards?

    The introduction of the fifth generation of mobile networks promises to be a revolutionary breakthrough in the field of communication through the following innovations:

    • Massive MIMO - This technology involves the use of multiple antennas on transceivers. As a result, the data rate and signal quality will increase in proportion to the number of antennas due to the diversity of reception.
    • New range - Today LTE networks occupy frequencies below 3.5 GHz. 5g standards imply the use of higher frequency bands. This will get rid of interference but will make to increase the power of transmitters and more densely place the base station.
    • Network slicing (network slicing) - This technology allows mobile operators to deploy logically isolated networks, each of which will be allocated for certain needs, for example for the Internet of things, broadband access, video broadcasting and so on. Thus, the new generation mobile network will be able to adapt more flexibly to different applications.
    • D2D (Device-to-device) - Devices that are close to each other will be able to communicate directly.

    What do we get from the introduction of 5G?

    The first and most important consequence of 5g implementation is a significant increase in data transfer speed. In the course of preliminary testing, it was recorded the achievement of peak performance at the level of 25.3 Gbit/s. if we talk about the real speeds that ordinary users expect, then in 5G they will reach 10 Gbit/s.

    Quote

    This means that you can download movies in Full HD in seconds.

    For comparison: now the maximum speed of 4G subscribers rarely exceeds 100 MB/s Most network bandwidth will be useful for live broadcasts of high-definition video, virtual reality applications, an organization of systems of remote training.

    Another 5G reduces the signal delay to 1 millisecond. Recall that now the delay can reach 10 milliseconds in 4G networks and 100 milliseconds in 3G. This improvement will enable mobile connectivity to be used even in situations where response time is critical. For example, for remote control of agricultural machinery, industrial robots or unmanned vehicles.

    The global spread of fifth-generation networks is likely to lead to the gradual death of Wi-Fi. Your smartphone, tablet or laptop will always and everywhere have access to the Internet, regardless of whether there is a nearby router or not.

    Will my smartphone work on the new network?

    No. To use all the features of next-generation networks, you will need to have a smartphone that supports them. It is already known about the upcoming release of several such devices. Among them are Xiaomi Mi Mix 3, Samsung Galaxy S10, Motorola Moto Z3, ZTE 5G, Huawei Mate Flex, Oppo F11 Pro, Nokia 10 and some others.

    However, do not rush to be at the forefront of buyers. 5G technology is actively developing, its standards have not yet been approved. It is possible that the final implementation will be slightly different from the current one, so the devices sold now will quickly become obsolete. In addition, 4G mobile networks have not fully exhausted the potential of their development.

    When to Expect?

    Now in many countries are testing 5G. The full launch of the first networks of the new generation is planned not earlier than 2020. This is likely to happen in the Asian region.

      As it turned out at the conference, the new network is not only the fastest in the world but also a network that will completely change our lives and affect global communications. "5G will have a huge impact on people's lives," says Laila Worrell, CEO of Altran North America, a high - tech engineering company. "We will all witness great progress and new technologies, the main culprit of which will be the new network."
      5G and drones
      BMW iNEXT model should appear on the market in 2021. Unmanned vehicles have long been objects that everyone was waiting for and wanted to see for a long time. And the new 5G network has made these ideas a reality.
      Unprecedented speed

      Experts say that 5G can become 100 times faster than 4G, and a huge number of devices can simultaneously connect to the network. This will allow vehicles to communicate with each other in real-time: they will know when another vehicle is changing lanes or braking and can influence traffic accordingly.
      For example, the electric SUV BMW iNEXT is equipped with sensors that collect and process data from the situations around it. This car is constantly studying and analyzing the road, and then sends information to the cloud, generating a real map in real-time, which, in turn, applies to all other cars.
      5G and beekeeping

      The benefits of 5G do not end there. The network can also have a beneficial impact on the environment when used in agriculture. David Houghton, General Manager of Asset Tracking Solutions at NimbeLink, explains how 5G and the Internet of things can help protect honeybees and accelerate the production and delivery of this product worldwide. "Tracking devices will be able to monitor the condition and safety of the hive," he says. Thus, a whole system of tracking and control of hives has been developed, with the help of which data such as temperature and humidity are determined by sensors and transmitted to the main computer.

      5G, the next-generation communication standard, will support the Internet of things, smart cars, and other technology. The new mobile standard will not be available until 2020, but the relevant specifications are being developed at full speed, and it becomes clear that the 5g standard will be significantly different from 4G. We are talking about increasing the speed of information exchange for mobile phones and tablets and a variety of other solutions, each with its own requirements.
      Predictions from Ericsson
      How 5G technology will work and why it is needed if the ultra-fast mobile Internet exists now?
      According to Ericsson, the future looks like this.
      Unmanned and networked vehicles will share information with each other. In the event of an accident, the car closest to the scene of the accident will report it to all cars following it. This will allow them to reduce the speed in advance or, in the case of traffic jams, to calculate a new route.
      Vehicle sensors will measure weather conditions more accurately and send data via the 5G network so that the vehicle calculates the best driving route.
      In the field of public transport, the 5G network will allow real-time tracking of the number of waiting for passengers at stops. The bus driver will miss the stop without passengers, and the Manager will send additional transport to their places of congestion.
      In the 5g era, all home electronics will be interconnected. If earlier when moving from one room to another had to carry a portable device to continue, for example, to listen to your favorite radio station, now the speakers in different rooms will contact each other, and listening will continue from the interrupted place. In addition, it will be possible to monitor the energy consumption of each device or find out how much electricity is produced by solar panels.

      The 5G network will change emergency services, providing reliable emergency communications and prioritizing police and emergency communications. And firefighters in helmets with cameras will broadcast the image to command and receive help in difficult rescue operations.
      5G - Technology
      In the past, we managed to streamline most of them, but the selection of technologies that ensure their practical application continues.
      Among them:
      ultra-high frequencies, which previously seemed impossible to achieve, will provide much greater speed; developing systems, sending data in tiny parts, will extend the work of the Internet of things devices for many years; reducing delays for tasks that require an immediate response. 5G - Network Speed
      Evaluation of the increase in the speed of the standard 5G compared to the previous is ambiguous. Ericsson managed to achieve growth in 50 times - to 5 Gbit/s. Samsung reached the figure of 7.5 GB/s with a strong signal of 1.2 Gbps in moving at the high-speed cars. The EU – China partnership intends to increase the speed of 5G by 100 times. NTT DoCoMo, a Japanese mobile operator, together with Alcatel-Lucent, Ericsson, Samsung, and Nokia is trying to reach 10 Gbit/s. and scientists from the University of Surrey suggest a speed of 1 Tbit/s. It is expected that over the next 10 years the speed of mobile networks will grow a thousand times.
      The increase in speed will require better antennas and equipment, as well as an expanded frequency spectrum. In the US, the process of allocating this resource has already begun.

      Internet of Things
      With lower connection costs, more devices have access to Wi-Fi. The concept of combining phones, coffee and washing machines, headphones, lamps and everything else into a single network is called the Internet of things. By 2020, it is expected that there will be more than 26 billion such devices in the world. And the number of connections will be even greater.
      The ability of things to "feel" with the help of sensors and remotely run commands can be used in urban planning, technology, smart homes, control systems of heat and electricity, security, health, public transport, retelling.
      The Internet of things requires a small connection speed, but for a huge number of devices. Already operate a dedicated network that uses a narrow frequency band, and the developers of the 5G standard want to take part in this process. Thus, telecommunication networks will have to support not only mobile users but also "smart" things. The management of such heterogeneous traffic is called upon to come to the aid of a new standard.

      Delays
      Obviously, the next generation 5g network will support unmanned vehicle technology and augmented reality applications. In this case, the information should be received in real-time. The time of reception and transmission in 4G networks exceeds 10 MS, which is very much. The future standard can completely change the network architecture by moving data storage from data centers to end nodes, including smart devices.
      A moving car, for example, requires information about the location of the nearest vehicle. Existing networks with the flow of such data for three cars cannot cope. Large data transfer delays require local data allocation.
      It is assumed that the responsiveness of the next generation of networks will be the maximum. The delay in data transmission will not exceed 1 MS, even if the speed of the terminal 500 km/h. This latency will be the main driving factor in the creation of new technologies, such as driving in city traffic surgery a distance.

      Reach consensus
      If the situation with the definition of the range of potential technologies in 2015 has improved, the technology itself is still being developed. It is necessary to determine which 5g technologies are needed first and which will be implemented after.
      Despite the lack of standard and confidence in the priority of technologies, manufacturing companies are trying to lead the development and implementation of 5G technologies to take a profitable position in the future.
      Nokia in April 2015 announced the acquisition of Alcatel-Lucent for 16.6 billion us dollars, and the US telecommunications company Verizon Wireless said that the first 5G-network in the US will appear in 2016.
      First Signs
      Prototypes of 5G networks have already appeared. The first 5G network was launched in South Korea. SK Telecom introduced the new technology at the opening of the research center, which will be engaged in its development. And by the XXIII winter Olympic games 2018 in South Korea, the company plans to build a 5g network across the country.
      NTT DoCoMo also intends to launch a 5G network in Japan for the 2020 summer Olympics in Tokyo.

      5G network against the United States
      Like previous standards, the 5g standard is developed by the 3GPP consortium and approved by ITU, the International Telecommunication Union. Don't want to stay on the sidelines and manufacturers. In October 2015, some regional groups agreed to meet every six months to develop a common position on the 5g standard.
      A similar agreement was reached in September 2015 between the EU and China. Ericsson and TeliaSonera reached a strategic partnership agreement to provide mobile operator customers in Tallinn and Stockholm with access to the 5G network in 2018.
      As can be seen, the countries of the world agree on cooperation in this area. All, except the United States, accustomed to occupying a leading position in everything.

      4.5G preparing for the future
      Qualcomm has offered 4.5 G LTE Advanced Pro technology, which is planned to be implemented over the next four years. This enables the company to support both the wider range of frequencies required by the 5G standard and previously deployed LTE networks, which will reduce latency and increase throughput.
      Features of the network:
      High throughput by combining the spectra of frequency; support 32 operators at the same time and increase throughput by combining the frequency and distribution of network traffic between operators; a 10-fold reduction in latency compared to LTE Advanced when using existing towers and frequencies from 1 MS to 70 MS; the use of the resource of the incoming communication lines to outgoing needs; increasing the number of antennas on base stations to increase coverage and signal strength; increase energy saving of IoT devices by narrowing the range to 1.4 MHz and 180 kHz (up to 10 years on a single battery); 1 Gbit/s for information exchange between cars, pedestrians, and IoT devices; scanning the environment without turning on Wi-Fi or GPS on a mobile device. Technological barriers
      Fraunhofer Institute of telecommunications in Berlin conducts experiments with frequencies of 40-100 GHz, Samsung uses in its experiments the frequency of 28 GHz, and Nokia – more than 70 GHz.
      The operation of devices in the millimeter-wave range has such a feature as extremely poor signal propagation, the power of which falls significantly with the distance from the base station. In addition, signal interference can be caused even by the human body.

      Solution-MIMO
      The output is the use of technology MIMO (Multiple Input Multiple Output) when send and receive multiple signals simultaneously. Now it is used for LTE and WLAN. For high frequencies, Massive MIMO – technology of reception optimization is used, when dozens of small antennas are placed in mobile devices and hundreds – in the transmitter.
      Manufacturer of antennas, SkyCross has created a system of 4x4 MIMO, which can be used in terminal size 16x10 cm Is much larger than antennas for LTE. For example, the size of the LG G4 15x7,6 cm, Samsung Galaxy S6 - 14x7 cm, while the Apple iPhone 6 Plus – 16х7,8 see the 4x4 MIMO System is not new – except the terminals are LTE-Advanced, it is used in satellite television systems, stringent requirements for size and power consumption will be charged. Thus, the creation of a small mobile device with 4 antennas will be a test for designers.
      The development of portable terminals will also require a lot of effort. According to the representative of Texas Instrument, the creation of chips capable of transmitting data at high frequencies will require the use of new technologies. In 2015, the project to create the 5g standard was officially named IMT-2020. It is a pity that the rest is still not seen at the end of the process.

      Fifth-generation mobile networks have already begun to be deployed around the world, and telecommunications companies are continuing to refine and improve their technologies. For example, Ericsson has announced a new record for data transfer rates using 5G technologies when using commercial equipment.

      According to the company's report, it managed to achieve a download speed of 4.3 Gbit/s in 5G networks using proprietary equipment that combines 800 MHz of the millimeter-wave spectrum. According to Ericsson, this figure is higher than all previous records by an average of 1 Gbit/s. Information was transmitted to a test smartphone equipped with a 5g modem Qualcomm Snapdragon X55.
      According to Ericsson representatives, the new equipment will be used for commercial purposes by the end of this year. Earlier it was reported that the 6G network will allow you to download data at speeds up to 8000 Gbit/s, but you will have to wait for their appearance for another ten years.

      The global launch of 5G in China was planned for 2020, but suddenly on October 31, three local mobile operators began providing access to fifth-generation networks in 50 cities across the country. This not only made China the world leader in introducing new technology overnight but also strengthened the position of HUAWEI.

      The country's largest operator is China Mobile Ltd. launched a 5G network in 50 cities including Beijing, Shanghai, and Shenzhen, the cost of the basic package is about $18 per month. Competitors represented by China Telecom Corp. and China Unicom Hong Kong Ltd. also provided customers with access to 5G at comparable prices. The tariff for the most active users costs about $85.
      Operators planned to start operating networks only next year, but accelerated work in connection with US sanctions against one of the main suppliers of 5G equipment - HUAWEI. As a result, China has become the world's largest user of new networks, and in the USA, fifth-generation communications that do not use HUAWEI solutions are offered only in certain areas of some cities.

      Before the launch of the services, about 10 million Chinese people were pre-registered for using 5G. With the launch of the fifth-generation networks, they gained access to video and games at a higher speed, will be able to use more advanced applications for virtual reality and communicate via video communications with better quality.
      The level of next-generation communications in China is especially important for HUAWEI. Dominance in the world's largest market will minimize the impact of US sanctions. Despite pressure from the United States, in July, HUAWEI announced that it had signed more than 60 contracts for the deployment of 5G networks in different regions, including at least 28 European countries.

      5G technology promises incredible Internet speed and minimal latency. The Japanese operator decided to prove the advantages of fifth-generation communication in practice and arranged a real race between the signal at a frequency of 28 GHz and a high-speed train.

      The largest Japanese telecom operator NTT DOCOMO installed a mobile terminal on the Shinkansen N700S passenger train and located three base stations along the Tokaido-Shinkansen railway. All the transmitters were equipped with advanced beamforming and tracking technologies, with the help of which they transmitted video in the resolution of 8K to the composition, and in 4K they transmitted the image from external cameras on the train.
      The experiment confirmed that 5G communication is capable of supporting data transfer at speeds exceeding 1 Gbit/s. Representatives of NTT DOCOMO noted that throughout the segment the train moved at a speed of 283 km/h, which did not affect the stability of the connection.

    • Search engine marketing (SEM): the methods, techniques, safety

      What is search marketing? A few years ago, this term simply did not exist. However, the rapid development of Internet technologies has led not only to the emergence of this trend but also to its amazing popularity. At the moment, search marketing is known as an effective way of promotion, which includes a range of activities aimed at achieving only one goal - to attract customers.

      Table of Contents
      Definition Relevance Goals and Tasks Methods and Technologies Search engine optimization Contextual advertising Social networks Search marketing security Prohibited method: Disadvantages Definition
      If you have not encountered this term before, it's time to get acquainted with it. Search engine marketing involves promotion in search engines in order to attract the target audience. I must say that this is a whole system in which several specialists are involved. They are marketers, programmers, copywriters, designers, etc.
      Compared to other methods of search engine marketing on the Internet has a major advantage. It allows you to reach out to an audience that is interested in the proposal addressed to it. This is due to the fact that it comes to the search engine for an answer to your request. Offering what potential visitors need, you both benefit. Customers get what they're looking for, and you get real customers.
      Relevance
      Search marketing is still a fairly new technology. Therefore, users have a logical question: why is it needed and whether it is needed at all? Let's find out.
      So, the main task of search marketing is to attract potential consumers. And not random, but only interested. After all, the offer is addressed only to those who are already looking for a product or service that you are ready to offer.
      However, in order for a user to notice your website among dozens of competitors, it is necessary to use various methods of search marketing. After all, as a rule, scrolling through the issue, the user rarely browses more than ten sites. Competently using the latest technology, you can be in the top ten and get ahead of competitors in the fight for the attention of potential customers.

      The theoretical definition does not always give an accurate understanding. Let's try to find out how search engine marketing works and what it's for.
      So, suppose that a budding entrepreneur decided to open his own business – to sell lingerie in an online store. This is a popular product that is in demand.
      However, in any area, you need advertising that allows you to attract customers. Because their absence means no profit. For start-up entrepreneurs, all costs are on the account, and any advertising is not cheap.
      There are many companies that offer search marketing among other services. You can even link the amount of payment to the result or make parts. That is, first the entrepreneur receives real customers, and then from the profits makes the rest of the payment for such an unusual method of advertising. Convenient to all.

      Goals and Tasks
      Knowing the definition is not enough. You need to know for what purposes search marketing is used.
      Sales. This is the most obvious task that this method of promotion performs. It is necessary to attract interested buyers to the site who will make a purchase. Image. The more often a person will see the logo of your company, the more likely that he will remember you and sooner or later become a client. Reputation. If we are talking about the promotion in social networks, a large value can have reviews. It is advisable to find a way to encourage buyers to leave real reviews. The more positive opinions can be collected, the greater the level of confidence in the company among potential customers. Competition. The market for goods and services is currently oversaturated. That is why it is especially important to compete and win customers over to your own side. Information. You can offer users up-to-date information about the products and services they are interested in. Even if they don't buy anything right away, your company will become an expert for them. In the future, they can return, choosing you among the many competitors.
      Methods and Technologies
      You need to understand that SEM (search engine marketing) is the whole complex of actions, which may include website optimization, contextual and launching viral advertising, and on the Internet resource work more effectively, attracting target customers and converting them into real buyers. So, what are the technologies of search marketing?
      Contextual advertising. Targeted advertising. Search engine optimization. Social network. Let's talk more about some of the technologies listed above.
      Search engine optimization
      This is only part of the marketing campaign. It involves working directly with the promoted site. Moreover, search engine optimization can be both internal and external. In the first case, work with texts published on the website, metatags, links, etc. In the second case, efforts are aimed at increasing the number of links to third-party resources.

      There are a considerable number of factors that allow you to improve the position of the site in search results. A simple user does not need to know all of them. To do this, there is a separate profession, representatives of which are engaged in search engine optimization.
      Contextual advertising
      This system for placing paid ads, created by the search engines. Each user can create their own ads and thus attract the target audience to their own website.
      The advantage of contextual advertising is that the user does not pay for the fact of placing an advertisement. Payment is charged only if the user clicked on the ad and went to the specified site.
      Another important feature is that to get to the top lines do not need long and painstakingly to optimize the site. You can buy this place for a fee, exhibited by the search engine. It is difficult to predict how high the conversion will be in this case.
      Social networks
      These sites are incredibly popular among the population. It is not surprising that this is quite successfully used by marketers. In this case, often published interesting for users' materials, to support communication in thematic communities, etc. In a sense, marketing in social networks can be called hidden. In addition, this method of advertising is not suitable for all companies. Not every product can be advertised with beautiful photos on social networks and enticing texts.

      Search marketing security
      This question becomes relevant if illegal methods of promotion are used. Conventionally, they are called "gray" and " black".
      Above were described exclusively "white" methods of search marketing, which are loyal to the search engines. Such a conscientious promotion requires a lot of time and effort, but ultimately increases the reputation of the site and gives a reliable result.
      Why then use "gray" and "black" schemes? For the reason that not all site owners are willing to invest a lot of time, effort, and money in the fair promotion. However, you need to understand that when using unscrupulous methods then it will be extremely difficult to restore the reputation of the site or even impossible.
      Prohibited method:
      spamming; automatic link exchange and purchase; placement of links to non-thematic sites. Some of these methods can produce results, but they can also lead to a site ban. Then it will disappear from the search results. Is it worth the risk, each site owner decides for himself.

      Disadvantages
      Delayed result. It may take several weeks of hard work to see the first results of search marketing. We must understand that this is a task that involves long-term implementation. Do not take it, waiting for lightning-fast results. Dependence on competitors. Even if as a result of well-organized search marketing you will be able to be in a good position in the issuance, all at any time can change because of the actions of your competitors. Complexity. It is almost impossible to carry out the whole complex of measures to promote the company on the Internet alone. This requires a whole team of professionals, not random people. Financial cost. You will have to pay for both professional services and search marketing. For example, if we are talking about contextual advertising. You need to understand that the promotion cannot be absolutely free.
