Aomway Apexlink Pro: 40km+ Digital Video and Data Link Specifications
Core specifications
| Parameter | Specification |
|---|---|
| Technology | OFDM + MIMO with AES encryption |
| Frequency range | 4.2 – 6.9 GHz, custom channels supported |
| Channels | Up to 128 |
| Maximum bandwidth | 20 MHz with automatic bitrate adaptation |
| Receiver sensitivity | −115 dBm at 2 MHz |
| Transmission range | Over 40 km in a clean electromagnetic environment |
| Control latency | Below 5 ms (SBUS) |
| Video latency | Below 60 ms glass-to-glass at 1080P60; 30 ms with a higher camera frame rate |
| Codec | H.265 and VCC hybrid |
The link automatically detects interfering channels and frequency hops around them, so a busy site degrades throughput rather than dropping the link outright.
Interoperability
The Apexlink Pro speaks MAVLink and works directly with QGroundControl and Mission Planner, and it carries SBUS for vehicle control on the same link. A Type-C port lets you attach a smartphone for a live video feed. Practically, that means one radio link replaces a separate video transmitter, telemetry radio and RC receiver on an integrated airframe.
Link budget and range
Manufacturer range figures assume a clean electromagnetic environment and a properly matched antenna installation. Real range is governed by the link budget: transmit power, both antenna gains, feed losses and the receiver sensitivity above. The −115 dBm figure at 2 MHz bandwidth is the number to plug into a range calculation, and it applies at that bandwidth rather than at the full 20 MHz.
