Xining, Feb. 1 (Xinhua) -- With the vast expanse of land in front of you and the whistling wind in your ears, the vehicles gradually disappearing into the wind and sand, and the "no service" displayed at the top of the mobile phone screen reminds you at all times that this is Hoh Xili, the real wilderness.
Over the years, the patrol members of the Hoh Xil Forest Public Security Bureau of the Forest Police Corps of the Qinghai Provincial Public Security Department have long been accustomed to the bumps in the mountain patrol road, but for them, what is more difficult than the wind and snow is the silent loneliness on the Hoh Xil wasteland.

In the past, every time we entered the mountain, we lost contact with each other, and we didn't dare to tell our family in advance, otherwise our family would be worried. Zhan Jianglong, a member of the mountain patrol team, told reporters that on the way to patrol the mountain, he could only occasionally report safety to his family through satellite **, and it was an unattainable dream for everyone to have a mobile phone signal in a no-man's land.
There's the Internet! When the patrol team gradually approached Zhuo Nai Lake, someone in the car shouted excitedly. The reporter took out his mobile phone and saw that the signal was full, and the 5G logo was re-lit. Zhan Jianglong told reporters that now, every time he walks near Zhuo Nai Lake, everyone can call ** and send WeChat messages to their families and colleagues as much as they like.

On May 31, 2023, the Zhuo Nai Lake Conservation Station, located in the hinterland of Hoh Xil, opened a 5G base station, marking that the central area of China's largest and highest World Natural Heritage Site can be connected to the world through 5G networks. Since then, Zhuo Nai Lake, known as the "Tibetan antelope maternity room", has realized the "long-distance, large-scale, all-round" real-time high-definition observation of ecological types, natural landscapes and wild animals in the nearby area through the remote supervision system of the ecological environment.
Hu Bo, general manager of China Mobile Communications Group Qinghai, introduced that China Mobile uses microwave long-distance transmission, solar pure optical power supply and other technical means to avoid the impact of traditional pole road erection on the ecological environment of Hoh Xil, and the area near Zhuo Nai Lake Protection Station realizes 5G network coverage, and the Internet transmission rate can reach up to 860Mbps.
The ability to use 5G in a no-man's land was unimaginable before. Zhao Xinlu, a member of the patrol team of the Hoh Xili Forest Public Security Bureau, said that 5G remote inspection makes the patrol work more convenient and efficient. In the past 27 years as a police officer, Zhao Xinlu has witnessed earth-shaking changes in the uninhabited area of Hoh Xil, from oil lamps to electric lights, from tents to board houses, from radio to 5G communications, from manpower patrols to first-class inspections, the ecological protection of Hoh Xil has entered a new stage.

Sun Lijun, deputy director of the Sanjiangyuan National Park Administration, said that the efficient and stable communication network is an important foundation for the "digital park" and "smart management park" of the Sanjiangyuan National Park.
Lian Xinming, a researcher at the Northwest Institute of Plateau Biology of the Chinese Academy of Sciences, said that in the future, AI recognition technology can be used to monitor the farrowing status of Tibetan antelopes to reduce manpower investment and statistical errors, and bring more convenience to the ecological protection and scientific research of Hoh Xil.
In the distant Hoh Xil, facing challenges such as high cold, lack of oxygen and extreme weather all year round, generations of mountain rangers have guarded the lives of Hoh Xil and defended their ideals and beliefs.
