At 12:52 this afternoon, a magnitude 6.8 earthquake struck Luding County, Ganzi Prefecture, Sichuan Province, which was strongly felt in Chengdu and other surrounding areas.

According to the news from the front, the communication in Luding city is basically normal. However, the earthquake disaster caused the interruption of communications in three townships.

After the disaster occurred, the major operators and equipment manufacturers immediately organized personnel to go to the anti-seismic front line to provide emergency communication support.

In addition to emergency repairs of ground communications (base stations and optical cables), Xiaozaojun learned that advanced air and space emergency communications equipment, including satellite phones and drones, had been put into disaster relief and played an important role.

█ satellite phone Xiao Zaojun just last week popularized satellite phone ("sources say Huawei Mate 50 series, Apple iPhone 14 / Pro will support" satellite communications ", so how difficult is mobile phone + satellite?). Unexpectedly, there was an emergency disaster this week, allowing satellite phones to play a role.

Take Tiantong satellite mobile communication system of China Telecom as an example.

According to China Telecom Satellite Corporation's statistics on the use of Tiantong satellite mobile communication service in the earthquake area, from 13:00 to 19:00 on September 4, the number of active users of Tiantong satellite phone in Sichuan region increased 10 times compared with that before the earthquake; the number of calls per hour increased 25 times compared with that before the earthquake.

Tiantong satellite phone, in the process of disaster relief, give full play to the role of emergency communications guarantee, fulfill the responsibility of "the heavy weapon of the country".

Tiantong satellite mobile communication system is the first satellite mobile communication system independently built in China, which has significant advantages such as independent control of resources and equipment, transmission security and interconnection with public networks.

The system realizes the domestic R & D and production of satellites, chips, terminals and gateway stations, ensures the communication security of users, gets rid of the long-term dependence on foreign satellite mobile communication services, and fills the gap of domestic independent satellite mobile communication system.

Another interesting emergency communication artifact for █ drones is drones.

As we all know, in last year's flood in Henan, UAV emergency communications played a huge role (pterodactyl communications UAV disaster relief). This time, there was a sudden strong earthquake in Sichuan, and drone technology was once again ordered to go to the front line for support.

According to on-site news, after the earthquake, the Sichuan Provincial Communications Administration Bureau and the Sichuan Provincial Emergency Management Department immediately launched a secondary response to emergency communications. From Zigong Aviation Industrial Park, Sichuan Tengdun Kechuang Co., Ltd. dispatched the "large-scale high-altitude whole-network emergency communication UAV"-double-tailed Scorpion UAV, to the disaster area to carry out emergency communication tasks.

The UAV has set up an "aerial base station", carried out public communication coverage tasks, and provided communication guarantee services for rescue and disaster relief commands and disaster victims.

It is reported that as early as February this year, Sichuan launched the "large-scale high-altitude network-wide emergency communication UAV platform" project.

In July, they completed the "actual combat" test of UAV carrying air base stations to realize network-wide emergency communications at Ganzi Kangding Airport for the first time in complex natural environments and real emergency conditions, such as "high altitude" areas and "no signal" areas.

The full preparation work has laid the foundation for the rapid deployment of UAV in this earthquake disaster, and fully proved the importance of emergency communication technology reserve.

It is worth mentioning that the earthquake prediction system also played an important role in this earthquake disaster, and the earthquake shear wave prediction was carried out in advance.

According to the news as of 19:54, the communications industry in Sichuan Province is making every effort to repair damaged communication facilities, dispatching a total of 360 support personnel, 120 emergency communication support vehicles, 219 power generators and 29 satellite phones.

Initial progress has been made in network repair by major operators, and normal communication services in the disaster areas are expected to be fully restored soon.

I hope the people in the disaster areas will be safe and resume normal production and life as soon as possible!
