This year’s national two sessions were broadcast live with 5g for the first time. 2019 is the year of 5g pre commercial, and “pre commercial” also starts with the frequent appearance of 5g video live broadcast.
Since the beginning of the year, there has been a “5g live broadcasting fever”
This year, at the second session of the 13th National People’s Congress, innovative applications such as “5g + 8K” HD video made its debut at the capital hotel where the Guangdong delegation is stationed.
The relevant person in charge of Guangdong Mobile told reporters that in the 5g scale test field in Guangzhou and Shenzhen, Guangdong Mobile has set up 360 degree HD cameras beside the Pearl River in Guangzhou and Shennan Avenue in Shenzhen respectively. Representatives can see the landscape of their hometown through VR glasses and other devices in Beijing, and can remotely control the camera to adjust the viewing angle and zoom the picture in real time, The distant picture is also clearly visible when enlarged.
Technicians told reporters that in the field measurement of Guangdong Mobile 5g, the 5g peak rate reached 1.8gbps and the delay was as low as milliseconds. In general, vertigo will be caused by time delay in VR experience. 5g low time delay can greatly improve the experience of the experimenter.
The reporter noted that since the beginning of the year, 5g video transmission application achievements have emerged one after another, setting off a wave of “5g video live broadcasting fever”, which began in February this year. The Guangdong Branch of the Spring Festival Gala of the year of the pig achieved a historic breakthrough. 4K ultra-hd content was transmitted between Shenzhen and Beijing through the 5g network provided by Guangdong Telecom and Guangdong Mobile, and then broadcast live at the Guangzhou flower market on the Lantern Festival, The 5g video live broadcast of Guangdong Mobile has “shown another hand”.
At present, 5g live broadcast uses WiFi
In this way, 5g video live broadcast “runs fastest” in various industrial applications. However, it is worth noting that the current 5g video live broadcast is only the initial stage. It actually uses WiFi rather than the well-known 4G wireless connection.
People from operators and enterprises told reporters that the contact method used in the 5g application test is through WiFi, that is, a 5g signal terminal is used as a “hot spot”, and then the 5g network is used by connecting the 5g signal sent by this hot spot. Its actual operation is the same as opening personal hot spots and sharing 4G network signals with mobile phones.
This means that in the current 5g video live broadcast, the 5g terminal and 5g communication vehicle provided by the operator are essential, which also limits its scene. In addition, the 5g terminal currently used by operators in live broadcasting is not a mobile phone, but a terminal the size of a suitcase.
