According to news on November 16, a new generation of 4G LTE communication network is in the ascendant, but it has been a hit. Some media said, "Easily paralyze a city! 4G LTE has been exposed to eight fatal flaws." In China, TD-LTE strategic opportunities are fleeting. The latest research found that 4G LTE has very fatal flaws, and the use of simple interference technology can completely paralyze the communication services of the entire city. Researchers claim that LTE actually has seven other such weaknesses (that is, a total of eight), any of which can be used with low-power transmitters to interfere with LTE signals. In addition, the LTE signal is very complex and contains a large number of subsystems. Any one subsystem can make the entire base station "rest". The domestic media industry poured cold water on 4G. Today, the People ’s Posts and Telecommunications published a commentary article saying, "TD-LTE strategic opportunities are fleeting." The comment said that even if TD-LTE achieved unconventional advancement within a short period of time, it still dared not slow down the pace of catching up. Currently facing "three mountains". 1. TD-LTE is still in the stage of scale testing in China, and the core equipment, chips, test instruments, terminals and other industrial links need to be further matured. Various signs indicate that in the next one or two years, nearly 40 countries and regions around the world will complete a new round of mobile broadband spectrum distribution, covering more than 60% of the global population. However, due to the slower than expected global commercial scale of TD-LTE and the lack of a strong market leader, many countries have re-planned the regulated TDD spectrum for FDD. In September 2011, Russia re-planned the use of Moscow's 2.6 GHz band, changing the previous TDD spectrum-based program to FDD-based; Saudi Arabia is also considering re-planning related frequency bands, planning to use FDD-based programs. 2. Regulatory agencies in most countries and regions require operators to obtain commercial spectrum within two years of obtaining spectrum. This means that the golden window for TD-LTE is only two to three years. TD-LTE must break through in a short period of time, otherwise, it may fall into trouble. 3. The industry chain's expectation for large-scale commercialization calls for the development of TD-LTE to speed up. If 4G fails to open up, the relevant manufacturers and all stakeholders in the industry chain will inevitably wait and see and delay the fighter. In March of this year, Hangzhou opened its first TD-LTE experience network. While experiencing the lament that “the speed of the network is fast and will not disconnect the networkâ€, they have issued inquiries: “Too few experience points, when will it be fully rolled out?†So far, more than 100 operators in 94 countries have installed LTE networks, covering nearly 500 million users, and according to Ericsson's projections, half of the world's population will enter the LTE era in 2017.
