Operating Frequencies

The DJI Phantom 3 Advanced (FCC ID SS3-WM3221510) operates on the following frequencies, as specified in its FCC filing:

These frequencies, situated within the globally recognized 2.4 GHz ISM band, are critical for both command/control and real-time HD video transmission. The output power of 550 mW allows robust wireless communication, contributing to the drone’s extended range and resistance to interference, while ensuring compliance with US regulatory limits for unlicensed devices.

Technology Deep Dive

At the heart of the Phantom 3 Advanced’s communication system is its operation within the 2.4 GHz ISM band—common to Wi-Fi, Bluetooth, and proprietary RF systems like DJI’s Lightbridge. This frequency choice balances range, throughput, and interference resistance, making it ideal for both control signals and HD video downlink.

Wireless Technologies:
– DJI Lightbridge: Delivers low-latency, high-definition video transmission, ensuring the pilot sees a live, smooth video feed with minimal delay. This is critical for precise framing and real-time piloting.
– Bluetooth: Present for auxiliary functions (specifics not detailed in the FCC filing), potentially for device pairing or telemetry.
– Wi-Fi/Bluetooth Coexistence: While the primary control and video links use proprietary RF protocols, the drone’s architecture ensures minimal interference with other common wireless devices.

Performance Implications:
Operating within the 2.4 GHz band provides a good balance of range and penetration, though it is susceptible to interference from Wi-Fi networks and other devices in urban environments. The relatively high output power (550 mW) enhances signal robustness, but also necessitates careful design to meet FCC Part 15C1 limits on emissions. The drone’s multi-layer PCB layout and EMI mitigation features (as observed in teardown images) further support reliable, interference-free operation.

Test Report Insights:
While detailed RF test reports are not summarized here, analysis of the internal photos and FCC documentation confirms the presence of robust shielding, ground planes, and component separation—all hallmarks of devices engineered for regulatory compliance and optimal wireless performance.
