At the second 5G millimeter wave industry summit forum, Wen Ku, vice president and secretary general of the China Communications Standards Association, said that 5G is currently gradually into the second half, 5G development is facing a huge task will be to expand the demand for and application of 5G, and 5G millimeter wave is an important support for the development of 5G. Qualcomm China R&D head Howie Xu also mentioned that in the case of low-frequency spectrum scarcity, exploring higher frequency bands is an inevitable trend.
5G application and prosperity can not be separated from the support of more spectrum, in the past 5G millimeter wave has been in a state of momentum because of the difficulty of coverage and high cost and other issues, but in the past two years, with the innovation and maturity of the technology, as well as various industries and a variety of application scenarios for the demand for a specific network, 5G millimeter wave began to gradually put into application.
When mentioning the topic of 5G millimeter wave commercialization landing, Howie Xu said, 5G millimeter wave is not suitable for all scenes, millimeter wave applicable scenes can be summarized in four words - hotspot coverage. For example, the internal network of enterprises, various large venues, large supermarkets, transportation hubs, industrial Internet and other applications are more suitable for 5G millimeter wave to play, because these scenarios are in need of high-capacity, high-speed, low-latency network support, which is the main characteristics of millimeter wave.
Howie Xu also exemplified several 5G millimeter wave applications, such as in the Super Bowl game site, whether it is the live broadcast of the game itself, or the audience's terminal equipment, will produce a very large demand for data transmission, this year's Super Bowl, the 5G millimeter wave network deployed in the game venue, for the entire stadium to provide a consistent high speed rate experience for the audience, through the 5G millimeter wave. The stadium was able to support can have a peak download rate of 3Gbps, which is 20 times higher than 4G LTE, and data that is difficult to achieve with Sub-6GHz.
Through this feature of millimeter wave, it also derives a lot of new applications for watching the game, such as the audience at the scene, in addition to feeling the hot atmosphere at the scene, but also at the same time with a 5G cell phone to switch to the field at any time the picture of the high-definition camera, so as to get richer details of the game, which is equivalent to have a more complete perspective. In the future, more new viewing experiences will also emerge with the popularization of millimeter wave, this year, China Unicom, GSMA, Qualcomm showed at the MWC in Shanghai with 39 ecological partners to create the "5G millimeter wave makes ice and snow sports more exciting" exhibition area, Qualcomm has teamed up with its partners to actively promote the testing of 5G millimeter wave, next year, viewers will experience smooth 4K or 8K live broadcasting Next year, viewers will be able to experience smooth 4K or 8K real-time live streaming content, and even develop more innovative ways to watch the games, such as VR/AR.
In addition to the just mentioned large stadium applications, 5G millimeter wave millisecond transmission and backhaul characteristics, in the very low latency relies on industrial automation scenarios are very applicable, with 5G millimeter wave, industrial manufacturing scenarios will have better network support for automated control, shop floor staff use VR, AR and other equipment to remote control of the machine, the accuracy will also become higher.
VR, AR is also 5G millimeter wave is very suitable for the scene, because this kind of terminal equipment needs to be real-time high-definition transmission, so the demand for high bandwidth is also very strict, 5G millimeter wave can meet such needs, with the popularity of millimeter wave, the future of the VR/AR as the carrier of the game will also gradually popularized.
In the 5G industry applications began to expand in a large area, the demand for 5G millimeter wave is also more and more exuberant, in the past few years, in the favorable policy environment, the industry chain upstream and downstream cooperation to promote the commercialization of the 5G millimeter wave, the future, Qualcomm and other vendors continue to innovate the technology, the various terminal application enterprises continue to innovate the use of scenarios, the millimeter wave in China's development and application will be The development and application of millimeter wave in China will also develop rapidly, and all industries will benefit from the popularization of the new network technology.
