Zhao Houlin, secretary-general of the International Telecommunication Union, said in an exclusive interview with Xinhua News Agency during the 2017 annual meeting of the World Economic Forum (also known as the "Davos Forum Annual Meeting") that it is expected to achieve commercial fifth-generation mobile communications (5G) by 2020. Technology will broaden the road for the fourth industrial revolution and bring new opportunities.
As the specialized agency responsible for ICT standards within the United Nations system, ITU established the world's first radiocommunication rules as early as 1906. In 2000, ITU passed the global 3G standard, and 12 years later it finalized the 4G standard.
Talking about the development of China's communication technology, Zhao Houlin said that China has not participated in standard setting for a long time. In the 2G GSM era, China did not participate at all, but accepted the standard in its entirety. By the end of the 1990s, China proposed 3G TD-SCDMA enters the ITU standard and is developed in China.
China's main 3G mobile communication standard eventually became one of the three 3G standards approved by ITU in 2000. “3G is China’s first proposed standard and extends to 4G on this basis,†said Zhao Houlin. “China’s 4G LTE standard has played a better role in international standards, not only in China, but also in other countries. Country use."
The Davos annual meeting focused on the fourth industrial revolution in the past two years. This revolution is closely linked to information and communication technology, and the fundamental role of 5G is unquestionable. Zhao Houlin said that according to the current technical plan and assumptions, the transmission rate of 5G will be at least 10 times faster than that of 4G. "After the road widening, everyone's experience will be different. After widening, there will be a market after widening, and many ideas are in the past. Narrow roads can't get through."
For example, he said, intelligent driving needs to process a lot of data in real time to cope with the ever-changing road conditions. In the face of the massive data required by the Internet of Things, 4G can no longer meet the demand.
According to ITU's roadmap for developing 5G, they will begin to collect 5G technology solutions in 2017, and 5G standardization work will be completed no later than 2020.
Zhao Houlin revealed that the current 5G R&D competition in the world is accelerating. Although it has just entered 2017, “but now the program has come out, ITU is evaluating and concentrating on the program. The final technical parameters are finalized in 2019. year".
He introduced that in fact, some manufacturers will not wait for the 5G standard to be fully announced before launching 5G services. South Korea, Japan, the United States, Russia and other countries have entered the 5G trial commercial stage.
Zhao Houlin said that the 5G standard cannot be "a hundred flowers and flowers". Although everyone is proposing their own plans, they must find a plan that everyone can accept to promote. There are still about three years to go into the 5G era, and China is actively participating in it. "Traditional equipment manufacturers and operators such as Huawei and China Mobile are promoting the development of 5G technology."
With the improvement of people's quality of life, people's lifestyles have also become varied. Different kinds of recreational products are starting to appear in people's lives, such as electronic cigarettes. The emergence of e-cigarettes represents a part of young people's thinking and means that electronic products are beginning to show a trend towards diversity.
simply replace the pods. The Pod system uses an integrated pod rather than a tank for higher nicotine strength and provides low power traction. the Pod system is rechargeable and has a longer life and higher battery capacity than disposable electronic cigarettes.
Our company Pod system has a built-in 380mAh battery and a USB charging port on the bottom. In comparison, the Pod system has a built-in battery of only 180mAh, but the Pod system charges much faster.
Our electronic cigarettes are of rechargeable construction. The first time you use the charger to charge, it is recommended to use up the remaining power before filling up, this is to ensure the performance of the battery.
