On February 23, MWC Shanghai Exhibition opened. 5g is the focus of this conference, especially the faster 5g millimeter wave technology, which has become the key to the next stage of 5g.
According to GSMA's prediction,By 2034, the economic benefits of using 5g millimeter wave band in China will reach about $104 billion.
The 5g millimeter wave exhibition area is divided into six parts: sports experience, event presentation, high-speed transmission, good memory, terminal display and environment construction,Comprehensive display of athletes' competitive experience, 5g mixed reality smart snow field, 8K video transmission, 5g full view event service and free view event live broadcast and other diversified application scenarios.
In the 5g multi view live show, through the millimeter wave 5g multi view live show scheme of China Unicom, the media reporters can directly view the outfield of Zhangjiakou international cross-country skiing center, connect the UAV, head mounted camera and professional camera with the base station communication through wireless network, and send back the athletes' valiant and heroic posture in the national cross-country skiing center in real time from multiple angles, so as to realize the goal Multi angle live broadcasting of the competition field provides a variety of watching experience for the spectators.
At the same time, with the power of Qualcomm snapdragon 5g modem and RF system,There are many kinds of products on display, such as 5g millimeter wave terminal coverage module, mobile phone, CPE, PC, AR (augmented reality) and XR (extended reality) equipment, live backpack, robot and so onIt fully demonstrates the powerful technical strength of 5g millimeter wave to meet the requirements of high-performance applications.
Popular science materials:
Millimeter wave refers to electromagnetic wave with wavelength of 1 mm to 10 mm and frequency of 30 GHz to 300 GHz. Compared with sub-6g (below 6GHz band) 5g system, 5g millimeter wave communication has unique advantages such as bandwidth, delay and flexible elastic air port configuration, which can effectively meet the requirements of future wireless communication system capacity, transmission rate and differential application.
In the United States, the measured data of the existing network show that,The speed of 5g millimeter wave can reach 11 times that of sub-6ghz band.Especially for stadiums, conference centers, subways and other places with dense traffic, requiring large capacity and bandwidth network, millimeter wave has a very prominent advantage.
For example, as early as the 2018 Pingchang Winter Olympics, millimeter wave has been used in the audio-visual broadcasting technology of the event.
In the recent US Super Bowl competition, the 5g millimeter wave network deployed in the competition venue provides a consistent high-speed experience for the audience in the whole venue, with the peak speed exceeding 2.5Gbps, supporting the immersive multi view live viewing experience.
