Li Yue, President of China Mobile, delivered a speech at the China Mobile 2016 Global Mobile Partner Conference. He said that China Mobile is still focusing on 5G technology experiments this year. "Based on the 5G technology experiment, we will launch a large-scale 5G field experiment next year. We hope to promote 5G trial commercialization in 2018. For experimentation and commercial trials, our big goal is to achieve nationwide 5G commercial use by 2020 in accordance with the country's overall goal."
In addition, he said that there are 4G roaming of China Mobile at the end of this year at 4G.
The following is the full text of Li Yue’s speech:
I am very grateful to Mr. Wang Peng for the long-term presiding work for our China Mobile partners. I have made great efforts. Every step of our growth is inseparable from the help and support of our partners. I probably figured it out, we arrived. So far this is the fourth partner conference. If we add two developer conferences in 2011 and 2012, we are already in the sixth session. We feel more confident when we run more and more. Our partners have long-term help, care and support for China Mobile. The more we feel the opportunity of this industry, the more I feel that every step of our growth has benefited from everyone’s concern and benefit from everyone’s support. For our love, our China Mobile Internet benefits from the hard work and cooperation of everyone.
Just now Chairman Shang Bing comprehensively puts China Mobile's next development strategy and informs us of some of our development ideas. I will use this time to briefly introduce what we will do next in three aspects.
First, I will make an overall review of the overall development of our 4G.
China Mobile's 4G, we have only been doing it for three years. From 2014, 2015, 2016, three years, we have built the world's largest 4G network, and built more than 100,000 carrier-aggregated 4G base stations. The world's most downloaded 4G system in many hotspots, our business experience has also promoted the automatic opening of VoLTE in more than 300 cities. I remember here we have said that 2016 is our VoLTE commercial year, while 4G international roaming, although we are only doing TD-LTE, but 4G international roaming is close to 140 countries, the world has 4G's place has China Mobile's 4G roaming.
Let's take a look at our customers. The development of the customers benefits from the continuous enrichment of the terminal society. Up to now, there are more than 2,000 4G terminals to serve our customers. The choice of customers in the terminal is very strong, our various The brand of mobile phones has more than 600 brands. 4G has become the network with the most choices of customers. Our customer experience is also a good experience. For example, we have 93% of mobile phones, which is 93% of mobile phones sold online now. Both support VoLTE, and 4G terminal sales have reached a very high level. In 2016, nearly 400 million terminals were sold through our system. 4G has also created a miracle of very large customer development.
Just now Chairman Shang has already introduced that our 4G customers have exceeded 500 million. Our current 4G customers account for more than 30% of the global operators' 4G customers, indicating that the shortest time used in China has passed Europe and America. In the 5-6 years of 4G development, 4G users have the fastest download speed, and 4G users consume more than 1G per month, indicating that our development potential in this area is huge.
Let's talk about our application, the maturity of 4G promotes the arrival of the mobile Internet era. 4G really builds a very favorable bridge in the development of the entire wireless broadband. I just communicated with Lei, and the daily transaction volume of Xiaomi Mall is over 80%. It is done with a mobile phone. Why is so much business volume done by mobile phone? Why did our main e-commerce in the past few years rely on PCs? The main reason is that after 4G and 4G development, the time for customers to access the Internet has been significantly shortened, and the speed of customers' online access has obviously increased. Users are always on the Internet. Because they are always online, we have a lot of life, and people in all aspects of life are even more away. Do not open the phone. I believe that in the process of speaking, there are still many friends who are playing mobile phones. Mobile phones have become an integral part of our lives, so we say that 4G is driving the arrival of the mobile Internet era. We say that mobile changes life, and it really plays a role in 4G.
4G has brought great convenience to people and promoted a new system of e-commerce, real-time interaction, and live video broadcasting. What will happen next? The most popular word currently is 5G. Below I will report on China Mobile's ideas and ideas on 5G.
5G will change the rules of many of our industry developments. What is 5G? I will introduce it to you from three aspects.
The first is the network. 5G is a new system specially built for high-speed Internet access. First of all, it has a new technology to solve high-density networking, a new system of high-frequency communication, and some new network and network technologies, making 5G closer to people and closer to things.
With the rapid development of wireless sensing technology, 433 MHz wireless communication devices have been more widely used in portable devices, vehicle-mounted terminals, intelligent locks and other fields [1]. As an important part of wireless communication equipment, antenna is a key component that affects the overall performance of the communication system [2].
Domestic and foreign scholars have been exploring the 433 MHz printed antenna with high gain and miniaturization for many years. However, there are two main trends in the design of 433 MHz printed antenna by previous scholars: one is to sacrifice size to ensure high gain, such as the structural scheme in literature [3]; The other is to sacrifice gain to ensure size miniaturization, such as the scheme in reference [4].
Taking into account the effective size and gain characteristics of the antenna is the difficulty in the design of 433 MHz miniaturized printed antenna. Based on the research experience of domestic and foreign scholars on 433 MHz printed antenna, a 433 MHz miniaturized spiral printed antenna is designed based on the 1/4 wavelength monopole antenna. The simulation results show that the antenna occupies only 20×35 mm2 and the effective gain is -4.14 dB.
