Unmanned aerial vehicle (UAV) network communication technology is the key to realizing UAV cooperative operation, data transmission and remote control. With the wide application of UAVs in military, civil and commercial fields, networking communication technology is also evolving. The following are several main UAV networking communication technologies:
Wireless local area Network (WLAN) technology
Wi-Fi (IEEE 802.11 series)
Wi-Fi is one of the most commonly used technologies in drone communications, supporting high-speed data transmission and short-distance communication. Wi-Fi 6 (802.11ax) further improves transmission rates and network capacity, making it suitable for multi-drone collaboration.wireless router module
Mesh network
The UAV forms a self-organizing network through the Mesh network, and each node (UAV) can act as a repeater, extending the communication range and improving the network reliability.dual band router module

4G LTE/5G
4G and 5G cellular networks provide drones with wide-area coverage and high-speed data transmission capabilities. The low-latency, high-bandwidth features of 5G are particularly suitable for real-time video transmission and remote control.
NB-IoT (Narrow Band Internet of Things)
Suitable for low-power, long-range drone applications such as environmental monitoring and agricultural inspections.
Satellite communications technology
Low Earth Orbit Satellite (LEO)
Low-orbit satellites provide global coverage for UAVs and are suitable for long-range missions, such as border patrol, maritime search and rescue.router core board
Geosynchronous satellite (GEO)
It provides a stable communication link, but the delay is high, which is suitable for the task with low real-time requirement.
Dedicated radio communication technology
Peer-to-peer communication (P2P)
Direct communication between UAVs and ground stations or other UAVs is suitable for small-range missions.
Software Defined Radio (SDR)
Multiple communication protocols can be realized through software configuration to improve communication flexibility.
Optical communication technology
Free Space Optical Communication (FSO)
