Introduction
Maintaining a stable connection between drones and operators can be challenging in mountainous terrain, urban high-rises, or vast industrial sites. Traditional transmission systems may struggle with obstructions, reducing range and mission reliability. The DJI Matrice 4D Series addresses this with its groundbreaking airborne relay feature, where one drone serves as a signal relay station for another, extending connectivity far beyond line-of-sight.
What is the Onboard Relay Function?
-
One Matrice 4D drone hovers in position as a relay node, maintaining a direct link with the operator.
-
A second drone flies deeper into obstructed or distant areas, maintaining its connection through the relay drone.
-
This setup creates a multi-drone communication chain, extending the effective operational range.
👉 In practice: This means operators can fly drones in valleys, behind mountains, or across wide industrial complexes without losing connection.
Real-World Applications
1. Search and Rescue in Mountains
-
Traditional signals weaken in valleys or forested terrain.
-
A relay drone positioned at higher altitude ensures rescuers can maintain live video and telemetry from drones searching in deep, obstructed areas.
2. Public Safety in Urban Areas
-
Skyscrapers and concrete structures often block signals.
-
Relay functionality allows drones to operate beyond buildings while maintaining stable links with ground command centers.
3. Energy & Infrastructure Inspections
-
Long pipelines, remote wind farms, or power line corridors often exceed direct range.
-
A relay drone extends operations, ensuring continuous coverage over vast distances.
4. Defense & Security
-
Missions in GNSS-challenged or radio-obstructed zones benefit from multi-drone relay networks, ensuring uninterrupted communication and situational awareness.
Benefits of Airborne Relay
-
Extended Operational Range: Pushes beyond typical drone transmission limits.
-
Reliable Connectivity: Maintains video and control signals in obstructed environments.
-
Mission Flexibility: Ideal for complex terrains like mountains, cities, or industrial hubs.
-
Enhanced Safety: Reduces risk of losing connection in critical missions.
Why It Matters
The onboard relay function transforms the Matrice 4D from a single drone into part of a collaborative system, expanding what’s possible in enterprise operations. For industries and agencies operating in remote or obstructed areas, this feature can be the difference between mission success and failure.
Conclusion
With its airborne relay capability, the DJI Matrice 4D Series redefines what drones can achieve in extended-range and complex environments. Whether in mountain rescue, urban safety, or large-scale industrial inspections, this unique function ensures reliable communication where traditional drones fall short. It’s not just about flying further—it’s about flying smarter, safer, and more connected.
