Typical Case

Baicells Technologies Inc.

SkyCells-T series – China Mobile High Altitude Base Station Project
As the provider of China Mobile's first phased high altitude UAV base station system, Baicells’ drones were equippedwith Huawei RRU base stations (12kg) according to customer requirements. They were in flight continuously for 4 hours
at a height of 200 meters and 4 hours at a height of 100 meters.

SkyCells-T series UAV Base Station System Acceptance with China Mobile
Location: Sichuan Province / Anhui Province / Shanxi
Province / Zhejiang Province
Purpose: Acceptance of the delivery equipment of China
Mobile's high-altitude base station project
Objective: mainly test on communication service and theVoLTE voice service function after the base station reachinghigh altitude.
Result: The acceptance was successfully completed andapproved by mobile users in all provinces and cities.
