LTE as a long-term evolution technology, its follow-up

For people, 4G communication in the future does seem very mysterious. Many people think that the fourth generation wireless communication network system is the most complicated technical system invented by human beings. It is indeed the actual implementation process of the fourth generation wireless communication network. There are a lot of headaches in the technical problems, which probably won't surprise people at all. The technical problems of the fourth-generation wireless communication network are mostly related to the Internet, and it takes several years to solve. In general, to smoothly and comprehensively implement 4G communications, you may encounter the following difficulties:

LTE + standards are difficult to unify

Although in theory, 3G mobile phone users can carry out mobile communications worldwide, but because there is no unified international standard, various mobile communication systems are incompatible with each other, which brings a lot of inconvenience to mobile phone users. Therefore, the development of the fourth-generation mobile communication system must first solve the communication standards and other issues that require global uniformity, and the world's major communication manufacturers will continue to argue about this.

LTE + technology is difficult to achieve

Although 4G communication in the future can bring a bright tomorrow, don't expect to use this technology immediately, it will take about 5 years to release this technology. According to developers working on this technology, there are still a series of technical issues to achieve download speeds for 4G communications. For example, how to ensure the signal strength of buildings, mountains, and other vulnerable areas with obstacles. Japanese company DoCoMo said that in order to solve this problem, the company will test different encoding technologies and transmission technologies. In addition, there are technical problems in handover, which makes it easy for a mobile phone to lose contact with the network when it enters the coverage area of another base station. Because the architecture of the fourth generation wireless communication network is quite complicated, this problem is particularly prominent. However, industry experts say they believe the problem can be resolved, but it will take some time.

Limited LTE + capacity

People's deepest impression on the future of 4G communication is that its communication transmission speed will be greatly improved. In theory, its so-called 100MB per second broadband speed is faster than the latest mobile phone information transmission speed in 2009, which is 10KB per second. More than 10,000 times, but the speed of the mobile phone will be limited by the capacity of the communication system. If the system capacity is limited, the more mobile phone users, the slower the speed. According to expert analysis, 4G mobile phones will be difficult to reach their theoretical speed. If speed doesn't go up, 4G mobile phones will be greatly discounted.

The LTE + market is difficult to digest

Some experts predict that after 10 years, the third-generation mobile communication multimedia services will enter the third stage of development. At this time, the global 3G network has been basically established, and more than 25% of the global population uses the third-generation mobile communication system. Generation technology is still slowly entering the market. By then, the entire industry is digesting and absorbing the third generation technology. The acceptance of the fourth generation mobile communication system still requires a gradual transition process. In addition, during the transition process, if 4G communication is delayed due to a shortage of systems or terminals, then the technology known as 5G may threaten 4G's profit plan at any time. At this time, 4G's long investment recovery and profit plan will become Extremely fragile.

LTE + facilities difficult to update

Prior to the deployment of 4G communication network systems, most of the global wireless infrastructure was established based on the third generation mobile communication system. If it is to be transferred to the fourth generation communication technology, many wireless infrastructures around the world need to go through A large number of changes and updates. Such changes and updates are bound to slow down the speed at which 4G communication technologies fully enter the market and occupy the market. And by then, the 3G communication terminal must also be upgraded to a 4G terminal capable of higher-speed data transmission and supporting various data services of 4G communication, which means that the 4G communication terminal must be provided in time after the 4G communication network is completed. The production of communication terminals lags behind the network construction. However, according to certain facts, consumers will be expected to use stable 4G communication mobile phones two or three years after the date when 4G communication technology is fully commercialized.

LTE + and other related difficulties

Because the functions of mobile phones are becoming more and more powerful, and the wireless communication network is becoming more and more complex, the same goes for 4G communication. As its functions increase, its construction and development will encounter more difficulties and troubles than previous system construction. . For example, when each new device and technology is launched, the subsequent software design and development must keep pace with it in order to enable the new device and technology to be quickly promoted and applied. Unfortunately, 4G communication is still only in research. During the development stage, the specific equipment and technologies used have not been fully formed, so the corresponding software development will also encounter difficulties; in addition, the rates and billing methods are particularly important for the development of the mobile data market for 4G communications, such as WAP mobile phones. After the launch, users spent a lot of connection time to obtain information, and the charging method based on time and information content made it difficult for users to bear. Therefore, it is necessary to study the charging system based on 4G communication early to facilitate market development. In addition, 4G communication not only needs to distinguish between voice traffic and Internet data, but also needs to have the performance that can be used smoothly on the third-generation wireless communication network with a very slow data transmission speed. This requires communication operators to find a good one. The solution to these problems, and the solution must first accurately implement the 4G specification on a large number of different devices, and it will take several years to achieve this. Moreover, when 4G communication is really launched, there are not many experienced and specialized technical personnel who are familiar with 4G communication business. This will also delay the rapid promotion of 4G communication in the market. Therefore, when designing, installing, operating, and maintaining 4G, Communication specialists must also be trained early.

Therefore, in order to fully enter the 4G network, there must be a transition period of 3.9G to complete the unification of various standards.
