What is 4G LTE?

4G LTE is the general name of LTE network standards such as TD-LTE and FDD-LTE. In China, 4G network is still in the special period of TD-LTE, 4G LTE generally refers to TD-LTE standard network. LTE is the abbreviation of Long Term Evolution in English. LTE, also known as 3.9G, has the data download ability of 100Mbps and is regarded as the mainstream technology for the evolution from 3G to 4G.

The maximum data transfer rate of 4G LTE is higher than that of 100Mbps, which is 10, 000 times higher than that of mobile phones and 50 times that of 3G mobile phones. 4G mobile phones can provide high-performance streaming media content and become personal identification devices through ID applications. It can also accept high-resolution films and television programmes, thus serving as a link in the new infrastructure for merging broadcasting and communications.

LTE

4G LTE communication technology is not separated from the previous communication technology, but based on the traditional communication technology, and uses some new communication technologies to continuously improve the network efficiency and function of wireless communication. If 3G can provide people with a wireless communication environment with high-speed transmission, then 4G LTE communication will be an ultra-high-speed wireless network and an information superhighway without cables. this new network enables telephone users to connect wirelessly and in virtual reality in three-dimensional space.

Benefits of 4G LTE

1: fast communication speed

Since the original purpose of studying 4G communication is to improve the rate of wireless access to Internet by cellular phones and other mobile devices, the most impressive feature of 4G communication is its faster wireless communication speed.

Compared with the data transmission rate of mobile communication system, the first generation analog system only provides voice service, and the second generation digital mobile communication system only has 9.6Kbps transmission rate, up to 32Kbps, for example, the data transmission rate of PHS; third generation mobile communication system can reach 2Mbps The transmission rate of the fourth generation mobile communication system can reach 20Mbps, or even as high as 100Mbps, which will be about 10, 000 times the transmission speed of the latest mobile phone in 2009 and 50 times that of the third generation mobile phone.

2: network spectrum width

In order to make 4G communication achieve 100Mbps transmission, communication operators must carry out substantial transformation and research on the basis of 3G communication network, so as to make 4G network much higher than 3G cellular system in terms of communication bandwidth. According to executives of AT&T, which studies 4G communications, it is estimated that each 4G channel will occupy the spectrum of 100MHz, equivalent to 20 times that of W-CDMA3G networks.

3: flexible communication

Strictly speaking, the function of 4G mobile phone can no longer be simply classified as "telephone". After all, the transmission of voice data is only one of the functions of 4G mobile phone, so 4G mobile phone should be regarded as a small computer in the future. and 4G mobile phone from the appearance and style, there will be more amazing breakthroughs, people can imagine, glasses, watches, makeup boxes, travel shoes On the premise of convenience and personality, anything you can see is likely to become a 4G terminal, but people still don't know what to call it.

The future 4G communication will enable people not only to communicate anytime and anywhere, but also to download and transmit materials, pictures and images in both directions, and of course to play online games with strangers who have never met. There may be the annoyance of being locked with nowhere to hide forever by the online location system, but this is negligible compared with the convenience and security it provides.

4: high intelligent performance

The fourth generation mobile communication is more intelligent, not only in the intelligent design and operation of the terminal equipment of 4G communication, for example, the dependence on menu and scrolling operation will be greatly reduced. the more important 4G mobile phone can achieve many unimaginable functions.

For example, 4G mobile phones can timely remind the owners of mobile phones what to do or not to do according to environment, time and other set factors. 4G mobile phones can download cinema box office materials directly to PDA. These materials can clearly show ticket sales and seats, and you can use this information to buy movie tickets that you are satisfied with online. The 4G phone can be seen as a portable TV for watching live broadcasts such as sports matches.

5: good compatibility

In order to make 4G communication accepted by people as soon as possible, we should consider not only its powerful function, but also the basis of existing communication, so that more existing communication users can easily transition to 4G communication with the least investment.

Therefore, from this point of view, the future fourth generation mobile communication system should have the characteristics of global roaming, open interface, interconnection with a variety of networks, diversification of terminals and smooth transition from the second generation.

6: provide value-added services

4G communications do not evolve from 3G communications through simple upgrades, and their core construction technologies are fundamentally different. 3G mobile communication systems mainly take CDMA as the core technology, while 4G mobile communication system technology attracts the most attention with orthogonal multitask frequency division (OFDM) technology. Using this technology, people can realize wireless communication multiplication services such as wireless area loop (WLL), digital audio broadcasting (DAB) and so on. However, considering the transition with 3G communication, the fourth generation mobile communication system will not only use OFDM technology in the future. CDMA technology will cooperate with OFDM technology in the fourth generation mobile communication system in order to play a greater role. Even in the future fourth generation mobile communication system, there will be new integration technologies such as OFDM/CDMA, digital audio broadcasting mentioned earlier. In fact, the technology it really uses is the integration technology of OFDM/FDMA, which also uses the combination of the two technologies.

Therefore, the fourth generation mobile communication system with OFDM as the core technology in the future will also combine the advantages of two technologies, one part will be the extension of CDMA technology.

7: high-quality communication

Although the third generation mobile communication system can also realize all kinds of multimedia communication, the future fourth generation mobile communication system is also called "multimedia mobile communication".

The fourth generation mobile communication is not only for the increase in the number of applications, but more importantly, it must meet the transmission needs of multimedia, including the requirements of communication quality. To sum up, first of all, it must be able to accommodate the large number of users in the market, improve the poor quality of existing communications, and meet the requirements of high-speed data transmission.

8: high frequency efficiency

Compared with the third generation mobile communication technology, the fourth generation mobile communication technology uses and introduces many powerful breakthrough technologies in the process of research and development. for example, in order to further improve the backbone bandwidth of the wireless Internet, some optical fiber communication product companies have introduced switching hierarchical technology, which can cover different types of communication interfaces at the same time. In other words, the fourth generation is mainly the use of routing technology (Routing) based network architecture.

Due to the use of several different technologies, the use of wireless frequencies is much more efficient than second-and third-generation systems.

According to the most optimistic estimate, this effectiveness will allow more people to do more things with the same amount of wireless spectrum as before, and to do these things quite quickly. Researchers say download rates are likely to reach 5Mbps to 10Mbps.

9: the cost is cheap

Because 4G communication not only solves the problem of compatibility with 3G communication, so that more existing communication users can easily upgrade to 4G communication, but also 4G communication introduces many cutting-edge communication technology. these technologies ensure that 4G communication can provide a very flexible mode of system operation, so 4G communication is much easier and faster to deploy than other technologies. At the same time, when building 4G communication network system, communication operators will consider adopting the method of gradual introduction directly on the infrastructure of 3G communication network, so that the cost of operators and users can be effectively reduced. Some services, such as wireless instant connections for 4G communications, will be cheaper than 3G communications, according to researchers.

For people, the future 4G communication is indeed very mysterious, and many people think that the fourth generation wireless communication network system is the most complex technical system ever invented by mankind. Indeed, there are a large number of headache technical problems in the implementation of the fourth-generation wireless communication network, which probably will not surprise and surprise people at all. The technical problems of the fourth generation wireless communication network are mostly related to the Internet, and it will take several years to solve.
