Case Study: DJI Action 5 + MiNEMedia C300 Private Network Solution Powers Ultra Trail Marathon Live Streaming
Live streaming outdoor endurance events presents unique challenges that traditional broadcasting systems often struggle to overcome. Mountainous terrain, unstable public networks, long race durations, and highly mobile camera positions require a transmission solution that is both flexible and reliable.
During the Hezhou Gupo Mountain Ultra Trail Marathon, the production team successfully deployed the DJI Action 5 camera together with the MiNEMedia C300 live streaming backpack using a private network wireless direct connection architecture. The solution delivered stable, high-definition live coverage throughout the entire event, demonstrating its effectiveness for demanding outdoor sports productions.
Project Overview
On November 29, 2025, the Hezhou Gupo Mountain Ultra Trail Marathon was held at the Gupo Mountain Tourist Area in Guangxi, China. The event attracted more than 2,000 professional and amateur trail runners from across the country.

Unlike traditional city marathons, ultra trail races take place in mountainous environments where network coverage can vary significantly. Production teams must maintain stable video transmission while following athletes across forests, steep climbs, remote checkpoints, and long-distance race sections.
To ensure uninterrupted coverage, Shanghai Zhonglong Huanying Culture Media Co., Ltd. conducted multiple rounds of field testing before selecting the DJI Action 5 and MiNEMedia C300 private network wireless direct connection solution.

Challenges of Trail Marathon Live Streaming
Trail races are among the most demanding live streaming scenarios for broadcast teams. Common challenges include:
Mountain terrain blocking wireless signals
Weak or unstable public cellular network coverage
Long-duration live production requirements
Frequent movement of camera operators
Difficult equipment deployment across remote locations
High reliability requirements for professional event broadcasting
Traditional wired transmission solutions often limit operator mobility and increase deployment complexity. The production team needed a lightweight, flexible, and reliable solution capable of supporting continuous live broadcasting across the entire race course.
