The MWC 2015 World Mobile Communications Conference kicked off today. As the most influential event in the ICT industry, from March 2nd to 5th, the crowds are in full swing. Exhibitors released the latest technology and works to showcase their own, potential partners to negotiate business cooperation, the leaders are eager to look forward to the future of technology, the media and exhibitors eagerly flow to the various booths: a good time Lively scene. It must be said that MGA organizer GSMA has built a multi-party platform and stage. And on the stage of this year, who is the brightest? 5G is very dazzling.
When the 5Gs at the MWC show are hot, you are sure to have many questions. Is this 4G still not popular? 4G is still not used, 4G has just begun, 5G is what? Is 5G a flicker? 4G speed is enough, why do you need 5G?
Actually not, first of all, the concept of 5G. 5G is a general term for next-generation communication technologies after 2G, 3G, and 4G. Although there are currently no drafting standards and there are no uniform standards, there are several core principles that are mentioned by several major proponents:
First, the 5G network speed will be 10-100 times that of 4G, which is based on the 100G bandwidth of 4G network speed. The 5G network speed can reach the network speed level of 1Gbps-10Gbps.
Second, 5G has lower network latency than 4G, and the delay is changed from 50ms to 1ms.
Third, 5G can serve more devices to achieve a true Internet of Things. The number of 5G single-slide coverage connections is expected to increase from a few thousand to one million.
Fourth, 5G will introduce more intelligent factors, including smarter network management, advanced software-defined networks and other intelligent technologies.
5G network is born for Internet of Everything IoT
After talking about the concept, now, why is 5G not a castle in the air? This is because 5G is currently driven by realistic application requirements. Imagine that many bottlenecks in current technological breakthroughs are actually stuck in the network speed. Here's an example:
Taking autopilot as an example, to achieve safer and smarter autopilot, more powerful big data processing capabilities are needed. To build a more powerful capability means various contradictions such as the increase in the cost of the car and the increase in volume.
In fact, many problems with autonomous driving are universal, intelligent learning and summarizing optimization. The most powerful computer built in human history is actually the data center. In the future, autonomous driving needs the support of the data center. To obtain the support of the data center, it is necessary to transmit all kinds of environmental data encountered by the car to the data center for real-time and high-speed processing. At the same time, the low-latency network guarantees the safety of the car. Thus, this gave birth to one of the typical requirements of 5G.
Taking intelligent robots and industrial applications as examples, smart devices such as home robots and drones have the same contradiction as autonomous vehicles. It is also possible to further promote such applications through 5G.
Finally, taking various types of virtual reality applications as an example, when we need to transmit data from more powerful sensors in real time, such as real-time transmission of real scenes in another place, it is not 5G.
The application of various types of technology has evolved forward, requiring 5G technology; and the three characteristics of 5G technology will spawn a large number of applications with future imagination.
It can be said that 5G wireless communication is born for the Internet of Things IOT, not for speed. And the industry has reached a consensus agreement in this regard, the first trial commercial network has been launched in Japan, and the global 5G will be rolled out in 2020, industry leaders have begun to lay out technology and business, now really want Getting ready, 5G is not far away. The 5G era mobile phone is not just a simple mobile phone, he will be the center of the Internet of Everything, or there will be another center.
Let's take a look at the above figures. There is a lot of content. I will explain briefly: 5G will support an ultra-dense network, and this network is also a highly flexible and self-managed network, and can be divided into levels according to the density of the terminal, such as Can be divided into ordinary networks, dense networks and ultra-dense networks. One point to note here is that telecom operators' services require high quality of service QoS and large area coverage, which is currently being implemented in some short-range wireless communication networks, although Bluetooth wifi and so on are all mesh. Network evolution. These requirements are only possible if 5G is planned for the telecommunications network.
# 个家抢滩5G,剑指2020using #
Each family grabs 5G, and the sword refers to 2020 commercial
Facing the real needs of the industry and consumers, the keen technology industry has already been in the layout. From communication equipment vendors, chip manufacturers, to mobile phone terminal manufacturers, they have begun to propose or deploy their own 5G strategy.
Ericsson once again demonstrated the latest results of its 5G test bed at this show. After the test bed achieved a maximum rate of 5 Gbps in July last year, Ericsson demonstrated two technological milestones: 5G-LTE dual connectivity (5G) - LTE Dual ConnecTIvity) and 5G MulTIpoint ConnecTIvity, the former allows mobile devices to connect 4G and 5G simultaneously, while the latter allows devices to connect two 5G base stations simultaneously. These technologies are expected to be commercially available by 2020.
Huawei further demonstrated its wolf culture. Huawei's rotating CEO Hu Houkun directly shouted during the exhibition, and Huawei was the slogan of the 5G era leader. He further explained that 5G is not a simple network upgrade, but a comprehensive re-construction. Ultra-large bandwidth, ultra-low latency, massive connections, high-speed mobile, full spectrum access, etc. all require a new level of 5G technology. According to him, Huawei has been investing in 5G for 5 or 6 years, and has been deeply involved in the formulation and research of 5G standards.
At the MWC site, ZTE also demonstrated the technology called Pre-5G, which is to fully utilize the existing 4G platform and technology to realize some functions of 5G to achieve the goal of commercialization of 2020. From the MWC site, the Pre 5G still uses 4G base station equipment, which can achieve a peak rate of 400M, which is equivalent to 4 base stations of 4G, and the network deployment efficiency is greatly improved. The 4G mobile phone terminal is used in the field, but at the network speed, it can reach 30+Mbps/s, which is four times the speed of the ordinary 4G network.
At the chip level, Xie Qingjiang, general manager of MediaTek, also made it clear that MediaTek has invested in human resources and resources for 5G research and development. And when we sort out the strategies of each family, we will find that everyone is strikingly consistent and will be the target of 5G commercialization around 2020. In other words, 5G is not only a castle in the air, but also in the process of solid advancement.
Wireless catching up with cable Internet will eventually reshape the connection
do you remember? Once upon a time, we were amazed at the 1Gbps speed of the Google Fiber Plan. We were thinking about it, what can be done in such a fast network besides video applications? However, from the current 5G experiment, wireless transmission can easily exceed the speed of this limited fiber.
Constrained by many problems such as spectrum resources, spectrum fragmentation, environmental factors, and high cost, why is wireless network progress far faster than wired networks? There is no reason for him, there is only one truth: demand, demand, or demand. As described in the first part, many scenarios such as autonomous driving, artificial intelligence, industrial applications, etc.
When the speed is no longer a problem, what does all this mean? Imagine that when the network speed is not a problem, does the computing device need a separate CPU? Still need a separate storage device? And these similar imaginings have only just begun.
And when we think about the problem itself, when the speed of the Internet develops rapidly, the meaning of the word itself will be subverted and reshaped, and the era of reinvention will come. In this era, just like the era when the power grid and telephone telegraph network were invented and popularized, the network that connects computing devices and everything can be transformed.
And what exactly is this change? Analysts believe that:
At the first level, all smart devices can be connected to form a large artificial intelligence network, generating huge artificial intelligence that constantly evolves and learns itself;
At the second level, with a fast-transferring network, this super-intelligent intelligence can reach any location on the planet at any time, solve problems or help humans. Just as a big voyage connects humans in tandem, with the 5G network, human society will once again create new concatenations. From industry to medical care to social management, it can be done remotely, even through artificial intelligence.
So let us look forward to and participate in this era together.
