Wireless Video Surveillance: Sichuan earthquake relief application 4G Communication Technology

I saw a piece of news:"

According to media reports, on May 20, Sichuan Luzhou militia commandid successfully rescued a 170-hour 65-year-old woman, the news was first published to the outside world at the broadband wireless Internet access point of the News Center in Beichuan County. The broadband wireless system supporting the communication is called miwave, which is the first such system in large-scale disaster recovery in China.

The system is developed by institutions such as the Chinese Emy of Sciences Microsystems. It can be quickly deployed in the event of serious damage to infrastructure in the earthquake-stricken areas, implement broadband connections between rescue teams, disaster relief command points, and news stations, implement emergency communication between each other to transmit videos, and exchange information with the outside world.

This system is one of the important technical directions of the National 11th Five-year Plan "next-generation Broadband Wireless Mobile Communication Network" and a supplementary solution of China's 4G proposal. Its advantages in disaster relief are mainly manifested in its ready-to-use and high-speed transmission, and its system peak data transmission rate can reach up to MB ."

In terms of bandwidth, miwave is suitable for wireless network video monitoring. Currently, 4G is already in use when 3G applications in China are not available.
