Advanced Hardware, Robust Transmission

The RF unit’s high output can significantly boost signal penetration and coverage, ensuring reliable links through dense urban obstructions. With 12 internal and external antennas, each with both horizontal and vertical polarizations, it can deliver omnidirectional, high-gain coverage.

Automatic Multi-Band Selection

It can automatically shift across sub-2 GHz, 2.4 GHz, 5.2 GHz, 5.8 GHz, and other bands to help bypass interference and deliver a crisp, stutter-free video feed.

Gateway Mode Delivers Wide Coverage

In Gateway Mode, O4 Ground Station connects directly to DJI FlightHub 2 to deliver low-latency, high-bandwidth video feeds. For DJI Dock 3, this can extend coverage up to 30 km.

Relay Mode Ensures Offline Reach

O4 Ground Station allows operators to switch to Relay Mode in offline areas such as valleys or urban environments with severe signal obstruction. The ground station can be positioned at a high point to extend the drone’s video transmission range.

Durable Design, Smart Power

O4 Ground Station supports continuous, unattended operations in harsh outdoor climates. It has an IP67 rating against water and dust and can operate reliably in extreme temperatures from -40°C to 55°C. Additionally, it features a smart power management system that draws only 7 W on standby.

Supported Power Supply
  1. DJI Dock 3 PoE Output Port
  2. Third-party PoE Power Supplies:
    • IEEE 802.3bt Type 4 (PoE++): 52 V to 57 V output, max 99.9 W per port; operating range -40° to 55°C
    • IEEE 802.3bt Type 3 (PoE++): 50 V to 57 V output, max 60 W per port; operating range -30° to 55°C
    • IEEE 802.3at Type 2 (PoE+): 50 V to 57 V output, max 30 W per port; operating range -20° to 55°C
Non-standard PoE or Type 1 power supplies are not supported; the device will show a solid red indicator light if an unsupported supply is connected.
Type 2 supports Gateway Mode only.
Backup Battery
  • LiPo
  • Capacity: 3250 mAh
  • Energy: 23.4 Wh
Backup Battery Operating Time (at room temperature) Battery preservation mode is enabled by default when powered via PoE. In the event of a sudden power loss, estimated runtime is:
  • Gateway Mode: approx. 45 min
  • Relay Mode: approx. 30 min
Battery preservation mode: when powered via PoE, the system keeps battery voltage between 7.0 V and 7.4 V. If the battery voltage at insertion exceeds 7.5 V, the system will discharge it to the safe threshold before entering preservation mode; the battery will not charge to full capacity.
Battery discharge performance may decrease in low temperatures, reducing actual operating time.
Backup Battery Charging Supports 9V or 12V PD charging. DJI 65W Portable Charger is recommended before deployment. When fully charged, estimated runtime in Gateway Mode is approx. 2 hours.
Charge time (65W PD): approx. 2.5 hours

Charging with a 5V charger is only supported when the device is powered off.
Charging is only supported when the battery cell temperature is between 0° and 55°C.

Physical Characteristics
Ethernet Port Surge Protection WAN/LAN Ports: Ethernet interface supports up to 10kA (total discharge current) surge protection, meeting EN/IEC 61643-21 Category C.

RJ45 surge protection capacity is 1.5kA (8/20μs waveform), meeting the Category C protection level of EN/IEC 61643-21. Surge protection capability depends on the capacity and reliability of grounding. To minimize the risk of surges, please make sure that grounding is done properly during installation.
Operating Temperature
  • IEEE 802.3bt Type 4 (PoE++): -40° to 55°C
  • IEEE 802.3bt Type 3 (PoE++): -30° to 55°C
  • IEEE 802.3at Type 2 (PoE+): -20° to 55°C
The 55°C upper limit accounts for solar radiation. At -40°C, the device requires a windless environment; auto-restart after shutdown is not supported in windy conditions. Cold-weather heating startup requires IEEE 802.3bt Type 3 (PoE++) or above.
After storage or operation in extreme temperatures, allow the internal backup battery to return to between 0° and 45°C before charging.
PoE Auto Wake-Up When connected to a Type 2 or higher PoE power supply, the device supports automatic wake-up on cable insertion or power restoration.
Cold-Weather Heating Startup In environments from -40° to -20°C, the device can start up via cold-weather heating mode when powered by a PoE supply of 60 W or above.

Requires PoE supply of IEEE 802.3bt Type 3 (PoE++) or above.
