4G Connectivity on DJI Enterprise Drones

Before you start:
4G is an additional data communication channel. The drone must establish a radio control (RC) link before takeoff. 4G cannot arm and/or launch the drone.

1.1 What 4G Does

4G adds a secondary communication path to enhance connectivity during flight. Once airborne and the RC link is established, 4G can transmit:

  • Telemetry to AirHub

  • Live video

  • Remote control commands (when Remote Commands is enabled in AirHub and supported by the drone)

In short: 4G is a backup communication link that keeps the connection alive even when the RC signal weakens due to distance, obstructions, or interference.

1.2 What 4G Does Not Do

4G does not replace the remote controller connection.

Limitations of 4G:

  • You cannot take off using only 4G.

  • Control authority always stays with the radio controller.

  • If you lose both RC and 4G, the drone triggers its failsafe (typically Return-to-Home).

4G supplements the RC link, it does not replace it.

1.3 How 4G Appears in AirHub Cockpit

When flying through AirHub – Cockpit, you can see the 4G/mobile connection strength:

  • A mobile reception indicator appears on-screen, which shows the connection quality.

  • AirHub shows whether 4G is active and being used for video/telemetry transmission.

This helps operators confirm that the drone maintains a stable network connection when controlled remotely.

1.4 How 4G Appears in DJI Pilot 2 (Cloud API workflow)

When using DJI Pilot 2 with AirHub Cloud API, the DJI Pilot app displays:

  • 4G reception bars

  • Warning indicators when 4G quality drops

Indicator meaning:

  • Orange: degraded link (unstable or weak connectivity)

  • Red: critical/warning (coverage nearly lost)

These visual indicators help pilots decide whether to continue relying on 4G or switch focus back to the RC link.

Summary

4G improves connectivity, it does not start the flight.

  • The drone must take off using the radio controller link

  • 4G is used for telemetry, video, and remote control (when enabled)

  • AirHub Cockpit and DJI Pilot 2 both show 4G reception status, with clear warnings when reception is poor

4G is a redundancy layer that enables global operations, remote oversight, and remote control, but the RC link always remains the primary control channel.
