What role did the emergency communication command vehicle donated by visual power play during the epidemic?

These two days, I just saw a news report about the donation ceremony of video link electric emergency command vehicle, and I also knew for the first time how important this video link multifunctional emergency command vehicle played during the epidemic. During the epidemic, whether the network communication is smooth or not determines whether all the work can be carried out normally. The communication command vehicle deeply combines all kinds of big data such as people, cars and things, so as to achieve information barrier-free interaction, end-to-end transmission of instructions, high-definition real-time presentation of communication resources and content, and better serve various emergency rescue work during the epidemic.
