Prior to the arrival of 5G, 4.5G will become the next generation of 4G technology evolution. Yang Chaobin, chief marketing officer of Huawei's wireless network product line, said in an interview with Tencent Technology that as part of the 4G network evolution, 4.5G network is expected to begin commercial use in 2016.
At the Global Mobile Broadband Forum 2015 held yesterday, Hong Kong Telecom and Huawei demonstrated the world's first 4.5G (4.5G) 1Gbps (Gigabit per second) mobile network. Both parties demonstrated a network download speed of up to 1.2Gbps, claiming to be The world's fastest network specification.
Why do you need 4.5G? Last year, Huawei first proposed the 4.5 concept. Prior to the commercial use of 5G, Huawei believed that LTE still has a lot of room for development. At least, it faces a five-year window of opportunity.
From a technical point of view, compared to the existing 4G network, the 4.5G network will increase its bandwidth, network capacity, and latency. Specifically, the peak rate of the entire network can reach 1 Gbps. The network delay will be reduced from the current 4G of several tens of milliseconds to 10 milliseconds, and it can support the number of connections in the order of 30 billion to support the connection between people and things. And some things and things connected.
Huang Jinghui, Group Managing Director of Hutchison Telecommunications Hong Kong Holdings Co., Ltd., said that in the future, not only people, but more objects with sensors, the Internet of Things will be applied to transportation, navigation, smart devices, wearable devices, medical care, and home appliances. In other areas, smart homes, car networking, drones, robots, etc. will provide us with a variety of innovative applications.
For operators, 4.5G can solve the problem of LTE evolution. On the one hand, it helps operators to protect existing investments and supports the sustainable development and evolution of technologies. On the other hand, the above-mentioned bandwidth, latency, and other aspects have improved. Will help operators actively expand the vertical market, Internet of things and other fields.
For real-time services such as e-health, autopilot, and e-education, where the bandwidth requirement is high and the delay is very sensitive, the current 4G network is not very satisfactory and must be further reduced from the access network, core network, and transmission network. Hourly delay.
For users, "From the application level, one of the typical applications brought by 4.5G is to support ordinary users' experience of 4K HD video." Yang Chaobin said.
At present, 80% of high-end mobile phones already support 1K high-definition video playback, and existing 4G networks can basically meet the demand for high-definition video playback, but support for 4K and 8K ultra high-definition is weak, and 4.5G high-speed will meet. This also means that mobile phones supporting 2K and 4K ultra high definition video will become mainstream in the next two years. In addition, 4.5G will enable virtual reality glasses to move, immersive experiences can be ubiquitous, and can support virtual reality glasses to provide an immersive HD experience.
For Huawei, 4.5G will help its operators acquire more cakes and market share in the “open window period†before the official arrival of 5G. According to Yang Chaobin, from a long-term perspective, 4G, 4.5G and 5G will coexist for a long time. At present, Huawei has started 4.5 commercial operations with operators of Hong Kong Telecom, China Mobile (microblogging), Japan's hardware and software, and Norway.
According to Alex Sinclair, GSMA Acting Director General and Chief Technology Officer, the deployment of 5G will take a long time. Now deploying 4.5G provides a wealth of value-added services. "In the next few years, most of the investment will be invested in the evolution of 4G until 2020. By 2020, we expect that there will be 1.4 trillion US dollars in 4G investment in the world, so we will continue until 5G begins. Invest in 4G," he said.
At present, the 4.5 network is being scaled, and the popularization also needs the cooperation of mobile terminals. Currently, Qualcomm has developed a chip solution that supports multi-carrier aggregation technology. From Xiaolong 200 series to 400 series to 600 series to 800 series, carrier aggregation technology has been used throughout Qualcomm high-end, low-end Opteron processors.
According to Tencent Technology, the person in charge of the relevant handset manufacturers said that the 4.5G terminal will be launched in the second half of next year as soon as possible. It is 5 years before the industry's expected 5G commercial time, but the pre-competition for telecom equipment manufacturers has started from 4.5G.
