Operating Frequencies

The DJI Mavic 3E/3T (FCC ID SS3-M3E2206) operates across a wide spectrum of frequencies, as detailed in its FCC documentation. These frequencies support robust wireless communications for command, control, and video transmission, ensuring both range and reliability in demanding environments.

These allocations enable the drone to utilize both 2.4 GHz and 5 GHz bands for Wi-Fi and proprietary OcuSync transmission, enhancing resistance to interference and maximizing operational flexibility.

Technology Deep Dive

The DJI Mavic 3E/3T leverages a sophisticated wireless architecture, integrating Wi-Fi 6 (802.11ax), Bluetooth 5.1, and DJI’s proprietary O3 Enterprise (OcuSync) transmission. The use of dual-band (2.4 GHz and 5 GHz) wireless not only boosts range and data throughput but also enables dynamic channel selection to mitigate interference from crowded RF environments—a critical advantage for operations in urban or industrial areas.

Bluetooth 5.1 provides low-energy, short-range communication, likely used for device pairing, proximity-based features, or accessory integration. The high output power levels registered in the 2.4 GHz and 5.8 GHz bands support long-range, low-latency video streaming and command/control links, essential for real-time situational awareness and mission-critical reliability.

The absence of cellular technology (as reflected by the equipment class) channels all communication through robust, license-free ISM bands. This design choice ensures compliance with global standards while delivering the flexibility and performance enterprise users demand. Test reports confirm that the radio modules meet FCC limits for emissions and power, safeguarding both operational safety and regulatory conformity.

In-Depth Internal Component Analysis / Teardown

A close examination of the Mavic 3E/3T’s internal hardware reveals meticulous engineering, with each subsystem optimized for performance, reliability, and serviceability.

The first component photograph provides a detailed look at the drone’s GNSS receiver module. Dominating the PCB is a large ceramic patch antenna, centrally positioned for optimal satellite signal reception across GPS, GLONASS, and BeiDou bands. The surrounding gold-plated vias and ENIG finish ensure excellent signal integrity and reliability, while the prominent metal shield can houses the sensitive RF front-end, protecting against electromagnetic interference. The presence of a crystal oscillator and robust power filtering capacitors highlights the focus on stable, precise satellite tracking—crucial for the drone’s autonomous flight and navigation. Multiple fine-pitch FPC connectors interface this module with the main flight controller, reflecting a modular, service-friendly design. This GNSS module is a cornerstone of the Mavic 3E/3T’s navigation accuracy and operational safety.

The next image reveals a compact sensor or indicator module, exemplifying DJI’s approach to miniaturization and integration. The small, high-quality PCB is connected via a flexible cable, allowing installation in tight spaces—potentially near the gimbal or obstacle sensing array. A single prominent IC, likely a sensor or LED driver, dominates the board, with minimal supporting components, indicating low power consumption and a specialized function. The lack of RF elements or heavy shielding suggests this board is dedicated to sensory input or status output rather than communication. Its modular, gold-plated design ensures reliable connectivity and straightforward replacement, supporting the drone’s advanced perception systems or user interface features.

A densely populated PCB is showcased in the following image, most likely responsible for core processing or memory functions. At its center are two large BGA-packaged ICs, indicative of a main processor (such as a flight control SoC or image processor) paired with high-density memory. The multi-layer black PCB, with extensive via placement and robust grounding, is engineered for high-speed data handling and EMI suppression. Multiple power regulation components and test points reflect careful management of sensitive analog and digital subsystems. The gold-fingered connector suggests this board interfaces with major system modules, ensuring high-bandwidth data and power transfer. This board is central to the Mavic 3E/3T’s ability to process high-resolution imagery, execute real-time flight algorithms, and manage complex mission profiles.

Another internal photograph uncovers the drone’s main PCB, cooling system, and internal structure. The left side features a prominent GNSS patch antenna for precise positioning, while the central region is dominated by a substantial heatsink and fan assembly—evidence of significant computational power and heat generation, likely from an advanced SoC. Multiple FPC connectors and wire harnesses facilitate connections to cameras, sensors, and propulsion systems. The use of multilayer PCB technology, extensive EMI shielding, and active cooling exemplifies DJI’s commitment to reliability and performance under demanding workloads. This section integrates the drone’s power distribution, flight control, and communication subsystems, forming the backbone of the aircraft’s intelligent operation.

A further close-up highlights a sophisticated, multi-layer PCB with several shielded ICs. The central chip, likely a microcontroller or DSP, orchestrates real-time sensor fusion or flight control logic. The surrounding shielded areas protect RF transceivers and power management circuits, ensuring clean signal routing and robust operation in electromagnetically noisy environments. The dense layout of passives, crystals, and test points supports both manufacturing quality and future maintenance. This board likely manages critical subsystems, such as sensor aggregation, system health monitoring, or communication, reinforcing the drone’s mission-critical reliability.

The final image provides a comprehensive view of the main PCB and associated electronics after the drone’s top cover is removed.
