Trilogy of Passion: Tell you a real LTE

In the global deployment of LTE, China's three major operators are still in the so-called system, so-called license plates, the so-called business model of the struggle. Recently, Beijing Mobile also formally opened its LTE public testing activities, to the domestic hope that the pioneer users of LTE to bring a small surprise. But what is LTE, I think operators do not fully understand, the people are even more confused. So before LTE arrives in China, I try to explain to the people exactly what the lte,lte can bring. Any network technology, for operators, undoubtedly need to solve two problems, one is to make money one is to enhance the user experience. For the money problem, this is not the problem of Chinese operators, but all the operators in the world are facing problems, for mobile communications network, its money-making process is a long process, because its business model is the scale of investment, scale users under the long-term income model. And in the process, because of the development of technology, the increasing demand of users, pressure from competitors, etc., you can not stick to a network to make money, you must bite the bullet and constantly upgrade the network in order to maintain a lasting profitability, because this is a fully competitive industry, the quality of the infrastructure to determine the user's direction, The leadership of the infrastructure can promote the emergence of newer business models, thus determining the operators ' earning power. It is obvious that it is impossible to draw a scientific conclusion about a network making money without making money. As for the improvement of the user experience, we have a significant change from 2G to 3G, the rapid development of mobile internet in the past 4 years has already explained this problem, then LTE can give users what kind of experience, this is one of the direction of this article to talk about. This paper tries to explain what is lte! from three angles of network, application and terminal. Hope to bring you into the passionate LTE world. LTE Trilogy Network: Highways in a wireless city if you love Beijing, there are 1000 reasons, if you hate Beijing, there are probably only one reason-too much. If you love the Web, you can have 1000 reasons, but if you hate the Internet, there is probably only one reason--too slow! I often compare the communication network with the highway, according to statistics, mobile communication 90% of the use of the probability of the city, then the mobile communication network can be compared with the city road. We can see the upgrading of the communications network as a continuous expansion of urban roads, from one-way trails of 1 lanes to two-way roads in 2, 4 lanes, to today's two-way 8, 12 lanes. Of course, all kinds of lanes in the city are coexistence, two-way 8, 12 lanes is clearly more ideal, but in Beijing such cities are still not enough, road and car contradictions exist forever, as customers on the communications network has never stopped complaining. The development of urban roads and the development of wireless communication are similar, urban roads widened to a certain extent, it is difficult to expand, because the road on either side of the building can not be removed (a bit like frequency). Therefore, such as Beijing,The large cities such as the sea began to divide the fast passage on the city Road, to "intelligent traffic" to solve the special vehicles or the rapid adoption of the demand. This is almost the same as the technology of mobile communication at the present stage to solve the network congestion and improve the bandwidth. So how do you understand LTE? In today's mobile communications environment, 2G, 3G, even WLAN and other wireless technology will coexist, these can be seen in different times, to meet the different needs of the road. LTE can be seen as the city's new two-way, intelligent, multi-channel road, he is similar to some cities set up the whole elevated highway, shuttle in the city above, can run more cars, can drive faster, let the city run smoother. We can see that the future of mobile communication is the same as the stereoscopic traffic we are describing. Over the past more than 20 years, the development of mobile communications has brought about great changes in our lives, and the way human communication has been radically changed. With the development of mobile Internet, more and more functions are classified into mobile communication category, and the rapid development of intelligent terminal, "Mobile change life" can be realized. corresponding to the mobile communication technology is constantly updated, we use 1G, 2G, 3G, 4G, 5G and other proprietary terminology to explain the development of mobile communication technology, each generation of technology to replace the previous generation of technology as the basic premise. However, after entering the 3G era, due to the increasing tension of the spectrum resources of mobile communication, the city's site resources and so on, the renewal of technology seems less important, so the 2G used for several decades still plays an important role. At the same time, between the 3G and 4G technology has produced a large number of transitional technology, generally known as 3.5G, 3.75G and 3.9G, and some people collectively referred to as "after the 3G technology." These technologies are now widely used in different countries and different carriers, and coexist, and China's communication network technology has basically upgraded to 3.5G or 3.75G category. China Mobile, for example, is currently building a strategy for GSM, TD-SCDMA, LTE and WLAN four synergy, which is a coexistence and complementary strategy. Although the transition technology has greatly improved the network speed than the early 3G, it still has a big gap compared with the wired network, especially the optical fiber network. This is because in today's urban environment, network deployment is becoming increasingly difficult, coupled with increased customer demand for data services, resulting in slightly different perceptions of the network and customer experience. To meet the growing bandwidth requirements of customers, you can only rely on further upgrades of technology. And LTE is considered a "post-3G" period of revolutionary technology. and 3.5G compared with 3.75G, LTE uses more innovative technology, such as OFDM and MIMO, so that the uplink and downlink speed of the network close to 100M, especially in the spectrum utilization efficiency has been greatly improved, compared with 3G and its upgrade technology, a significant increase. As a result, 197 LTE networks have been deployed in 75 countries worldwide to meet new customer requirements. Today, the operation represented by China MobileBusiness is building a wireless city, LTE will undoubtedly become a wireless city in the highway, so that you can enjoy a wireless city experience different experiences. LTE is the two revolutions after 3G, and new services and business models will change the way you use your phone again. Some people will ask, 3G has TD-SCDMA, WCDMA, CDMA2000, and some other standards, now there are LTE and FDD LTE, they are different? This is actually a very technical topic, here a brief answer. 3G period, the three standards do have a big difference, from the name can be felt, but its basic technology CDMA is the same. Today, LTE and Fddlte are less different from names. In fact, the two types of technology are almost the same, mainly the frequency of the work is different, so you can completely ignore the problem of the system, that is, only one LTE. LTE Trilogy application: Revolutionary experience needs to create a common 2G voice, competition is the call quality, operating is the traffic volume, 3G to play mainly, competition is the internet speed, operating is the flow. 2G Competitive price advantage, 3G competition terminals and services. 2G selling is the card, simple marketing can be, 3G selling is intelligent, need to improve customer perception. This is a very wide range of Weibo on the 2G and 3G for customers to bring different perceptions of the jokes. So after 3G, what kind of experience does the current "gradual climate" 4G LTE bring to us? Many people have experienced the LTE test network built by China Mobile in many cities, it mainly through the LTE Wi-Fi mode to provide mobile high-speed Internet services to customers, perhaps because the end of the side and the lack of application side, only to adopt such an indirect way. Wi-Fi as the broadest access technology, can enable more terminals through LTE access to the Internet, so that more customers experience mobile high-speed network. Of course, a simple high-speed Internet experience is not the real advantage of LTE, LTE is known for its high capacity, high speed and low latency, and is seen as a revolutionary technology after 3G to create new services and business models, and its real meaning is to provide the industry with a new network platform to support more applications. This is because the LTE service is not only used in the mobile phone, in the LTE era, the number of devices can be accessed via LTE and other communication modules will be more than 5 times times the mobile phone, such as netbooks, tablets, outdoor electronic signage, car navigation and digital cameras. One of the features of LTE is the ability to significantly shorten the latency of communication, which is usually called low latency, which can be connected in less than 0.1 seconds, and the delay time in the wireless zone is less than 5 milliseconds. With the feature of low delay, many new high-end services can be derived. In the medical field, for example, early telemedicine was primarily a single mode of video communication. After LTE is introduced, doctors can diagnose patients directly through remote medical facilities, and even remote realOperation, which is because the low latency of LTE allows high-definition images, tactile manipulation, etc. to be passed on to the other side of the device, almost equivalent to field control. In addition, the "online confrontation game" is seen as an example of LTE's good application. Low latency reduces the transmission time of 1 data frames in the wireless access area and simplifies the network structure, plus a variety of handheld gaming devices developed by companies such as Microsoft, which feel almost as if they are playing in real life. In Japan, technicians have developed a service that provides instant interpretation via the LTE network, using a mobile phone with a supercomputer. When Japanese customers call American friends, they simply speak Japanese to their mobile phones, and the phone passes the signal directly to the supercomputer, which translates Japanese into English and "says" to each other. In this way, the mobile phone becomes an intelligent synchronous interpreter. With supercomputers, the way people look at their daily queries will change. In the near future, when you are looking for information about any object, just use the phone to capture and return the photos, the computer will tell you the price, service or related network search results, which is actually the combination of LTE high-speed network and cloud computing is one of the new services. Similar applications will be developed further, and the market based on the LTE communication platform will be expanded further. By pushing the platform, companies without a professional background can easily develop and use LTE services, which is the key to LTE's ability to revolutionize its customer experience. In the final analysis, what kind of experience can LTE bring to us? So far, LTE will change the way we think, live and business, and be full of imagination! The end of the trilogy: All kinds of terminals take us to the world if LTE is compared to a highway in a wireless city, the highway is not boring and boring, because many companies are involved in the operation and service of the highway, not only the roadside gas stations, as well as playgrounds, gymnasiums, cafes and cinemas ... Is it pleasant to have a Mercedes on a highway like this? The invention of the automobile makes human's moving speed and vision greatly expand, correspond to the field of communication, we want to swim the colorful network world to depend on all kinds of terminals, such as personal computer, PAD, mobile phone, smart glasses and so on. In the 2g/3g period, the so-called "terminal form" is still not much breakthrough, the company's core ideas or around people, only people can carry, call and the Internet is a communication terminal, such as pad and mobile phone. But in the era of LTE, terminal form will be greatly enriched. The previous section specifically emphasizes the technical features of many LTE, such as low latency, high speed and high capacity, coupled with China Mobile will promote the four-net Synergy development strategy, the terminal form will be separated from people-centered thinking, to expand to human and human, objects and objects and people and things in a wider range of areas. Of course, the original communication terminal form will certainly get the first development, such as supporting LTE data cards, smartphones and tablets will be the earliest terminal form. These devices have noThe size of the form is almost the same as the current popular terminal. The difference is mainly embodied in several technical characteristics and application perception, such as the internet speed will be faster than the current 3G a lot; playing online games on the phone will be faster and smoother. So what are the other forms of terminals? We should not confine ourselves to the scope of hand-held mobile terminals, but should consider the needs of other moving objects and people. In a variety of moving objects, cars are a stark example. Today, the car itself is a mobile LAN. Car networking allows the entire vehicle to be built on the basis of internal network systems and perceptual systems, giving users a safer, more comfortable and smarter driving environment. If the LTE module is also loaded into the automotive communication and network system, more unexpected application experiences and business opportunities will be generated. At present, the vehicle and the outside connection of the device is the navigation equipment, mainly through satellite communications to achieve, the application of a single, one-way navigation and application services. If the LTE module is implanted into the navigation device, the navigation device will become a mobile tablet, delivering business in two directions, which will greatly enhance its entertainment and service. With the development of large touch screen technology and the combination of LTE network, car front windshield will become a worthy of development and good use of the screen, in addition to the navigation map can be displayed on the windshield, there are more applications can be excavated. A lot of people have been to the car theater, just sitting in the car watching the big outdoor screen. Imagine what it would be like if a car's front windshield turned into a movie screen, and you were camping in the suburbs, sitting in the back seat with your lover eating popcorn and watching the blockbuster? You know, it's not a DVD. Oh, but the content of the video site on demand via the LTE network, is it a bit like Hollywood blockbuster? Do not believe that such a scene will soon be achieved. At present, in Hangzhou B1 Bus, China Mobile on each bus installed 2 LTE CPE, users can access the Internet through Wi-Fi access, enjoy a variety of mobile internet business. There will be a growing number of similar scenarios based on car use. For example, in the ambulance, embedded in the LTE module video and medical equipment, and patients, hospitals to establish real-time video links, to help patients will play a very large role; if there are video devices on the fire engine that support LTE, there are also monitoring devices that support LTE on the fire site, At the same time, the road to the scene have LTE real-time video traffic monitoring, then, fire engines can not only quickly arrive at the scene, and on the way to the real-time monitoring of the fire, greatly improve the efficiency of fire fighting. That is to say, moving objects such as cars will become the new terminal form of LTE. Of course, wearable equipment, such as smart glasses, smart watches, smart boots and other equipment has become a hotspot in the development of these devices, without exception will introduce the technical characteristics of LTE, so as to bring more unexpected surprises to users. In the LTE era, in addition to the traditional communication terminals, other forms of terminals willwith special applications. Any object is likely to be the terminal of LTE, which is the most valuable technology of LTE. How, see so much, is not to LTE have a deeper understanding of it! If your city has already opened LTE network, then want to experience it without hesitation, for many enterprises around mobile internet survival, hurriedly to realize your idea bar, business opportunities in front of you, LTE has come.
