Drone have captured the imagination of the public both for its novelty and the clear potential to simplify and enhance our lives. The drone market is expected to grow in the coming years. The global commercial drone market size was estimated to be USD 552 million in 2014 and is expected to grow at a CAGR of 16.9% over the forecast period.
V2X is a technology that aims to improve traffic safety and efficiency. A typical use case is forward collision warning. When a vehicle emergency brakes, aV2X system receives the car’s messages, issues a warning, preloads the brakes to slow down. This requires the V2X system to provide reliable communication at high travel speed. And to give drivers sufficient response time, it also must be low latency and cover a long range. These are similar to the requirements for Drone communications, making it a promising candidate for technology transfer.
2.Video streaming by IEEE802.11p
In China alone, there were more than 400 drone companies in 2015. In this fast-growing market, it is important for drones to differentiate themselves. To differentiate, DJI has developed a video transmission system Lightbridge that has led to the success of its Phantom series.
2.1 Current technologies for video streaming
We can classify current technologies in the following four categories:
- Analog video transmission
Analog video transmission systems have bigger size and consume more power to reach the same distance compared with digital. Another weakness is its poor resistance to interference. Therefore, analog has been replaced by digital systems in most products. However, its low latency characteristic still makes it popular among drone racers who want real time video displays with zero latency.
After analog systems, Wi-Fi has become the most popular solution. It provides enough data throughput and is offered at a very
