What are the communication technologies for UAV/Drone networking?

UAV networking communication technology mainly includes the following:

Self-organizing network module technology: This technology is flexible, dynamic, and anti-interference. It can dynamically adjust the network structure according to the location and motion state of the UAV to ensure the continuity and stability of communication.

MESH broadband self-organizing network communication technology: This is an important direction for UAV aerial networking and wireless communication applications. It can temporarily, dynamically, and quickly build a distributed, decentralized, autonomous, and dedicated network with the characteristics of self-organization and self-recovery.

Flying self-organizing network (FANET): Based on self-organizing network technology, it provides reliable and real-time network communication for UAV groups, becoming a good solution to solve the communication problem between multiple UAVs.

UAVCAN communication protocol: This is a UAV communication system based on the airborne network communication protocol, which aims to provide efficient, reliable, safe and flexible airborne communication solutions, and supports the integration of various UAV sensors and controllers.

MAVLink communication protocol: An open source lightweight message transmission protocol, widely used in the communication between UAVs and ground stations, supports various types of UAVs and ground stations, and can realize the control, status and data transmission of aircraft.

OFDM-based communication technology: It has high spectrum efficiency, strong anti-multipath interference ability, supports high-speed data service transmission, has "non-line-of-sight" and "diffraction" transmission characteristics and good penetration ability, and can meet the wireless communication tasks of UAVs.

COFDM full digital modulation and demodulation technology: combined with MPEG2/MPEG4 digital compression encoding technology, it is used in UAV wireless video communication transmission system, which is suitable for diversified communication needs in complex environments.

TPUNB or LoRa wireless communication technology: adopts a low-power, long-distance transmission strategy, and can send a device wake-up command when the UAV arrives at the environmental monitoring area to realize remote wake-up of high-power devices.

These technologies together constitute the diversity of UAV networking communication technology, enabling it to achieve efficient and reliable communication in various complex environments.
