Applying V2X technology to drones
Drones have emerged as one of the fastest growing markets for a unique ecosystem of electronics. Drones need to navigate their environments and as a result will benefit from technologies that help them find their way and avoid danger. Fortunately, this technology already exists in different yet related technology areas. V2X (vehicle-to-vehicle and vehicle-to-infrastructure) communication using IEEE802.11p is a technology used to improve traffic safety and efficiency.

[3.2] Collision avoidance by cooperative flying

Cooperative flying already exists in the aviation industry. An example is Traffic collision avoidance system, which actively interrogate the  transponders of aircrafts and negotiates collision-avoidance tactics with them in case of a threat. However, TCAS is expensive, large and power hungry, and therefore appears only in large aircrafts. Fortunately, those issues can also be solved by V2X system. 

In V2X system, vehicles are required to broadcast their position, speed and other information to identify collision risk. The effectiveness of the V2X system has been proven in extensive field tests, such as Drive C2X in EU and Safety Pilot in US. In 2014, U.S. Department of Transportation published a V2V readiness report and pointed out that V2X can be highly beneficial in collision avoidance.


[4] Conclusions

Drones and cars have similar communication and safety requirements. IEEE802.11p based V2X technology is designed to provide reliable connections between vehicles and improve transportation safety. By applying V2X-based technology to drones, we can build an affordable HD video transmission system with much better performance than those based on consumer Wi-Fi solutions. Moreover, when standardized communication – such as that based on proven V2X technology – is established for drones, it will become possible to implement a real-time air space management system and collision avoidance system, further increasing the possibilities and market growth for drones.
