Operating Frequencies

The M1P, under FCC ID SS3-M1P1607, operates across several critical wireless frequency bands. These frequencies, as documented in the FCC filing, define its communication, control, and video transmission capabilities:

These bands, primarily in the 2.4 GHz and 5 GHz ranges, are widely used for high-throughput, low-latency data transfer—supporting both remote control and HD video streaming. The output power levels ensure a balance between range, penetration, and regulatory compliance.

Technology Deep Dive

The M1P’s wireless architecture leverages both Wi-Fi (2.4 GHz ISM band) and Bluetooth for seamless connectivity between the drone, remote controller, and user devices. The absence of cellular modules (Equipment Class: None) means all communication is local, reducing latency and enhancing user privacy.

Operating within the 2.4 GHz and 5 GHz bands allows the M1P to achieve impressive transmission distances—up to 7 km under FCC regulations—while maintaining robust resistance to interference. The device’s variable output power across frequencies ensures compliance with regional RF exposure limits and optimizes battery life. Higher output at 2.4 GHz supports long-range control and video downlink, while lower-power 5 GHz bands can help minimize interference in crowded RF environments.

The integration of GPS/GLONASS further augments situational awareness and flight stability. Advanced power management and EMI shielding, as evidenced in teardown photos, ensure that high-speed data and RF subsystems operate harmoniously without cross-interference—a testament to DJI’s engineering rigor.
