XINING — Tsesogyal has been notably excited during his recent patrols in Hoh Xil, Qinghai province, as he can now send frequent updates to his daughter. With the help of a 5G base station, he can call his daughter and send her photos of the Tibetan antelopes roaming in the hinterland of the Qinghai-Tibet Plateau.

Situated at an average altitude of more than 4,600 meters in the Sanjiangyuan National Park, the Hoh Xil Nature Reserve had long suffered from a lack of communication signals, except for the route along the Qinghai-Tibet Highway.

"Entering the nature reserve meant being isolated from the outside world, especially in the Drolkar Lake area. Patrollers could only contact their families through satellite phones," says Tsesogyal, a 27-year-old patroller of Hoh Xil.
