Preventing collision risks between drones and improving obstacle recognition
Overcoming the shortcomings of existing WiFi and LTE with an independent communication method With low-altitude drone communication protocols being adopted as international standards, different types of drones can now communicate with each other and fly safely.
▲ A communication protocol has been established to enable information sharing between different types of drones. The Ministry of Science and ICT announced on March 24 that four projects, including the standard for low-altitude drone communication protocols proposed by us at the ISO/IEC JTC1/SC6 international standardization conference, were adopted as international standard tasks together with the National Radio Research Agency.
The new projects adopted this time are ▲drone communication model and requirements ▲shared communication ▲control communication ▲video communication, etc.
Currently, each drone manufacturer has different communication standards, so information cannot be exchanged between different types of drones. This can lead to a risk of collision between drones during close flight, and it is also difficult for multiple drones to fly simultaneously.
However, the standard adopted this time enables sharing of information such as obstacle locations between different types of drones, which will allow autonomous prevention of collisions between drones or with obstacles, and is expected to increase the stability of drone operation.
In addition, by proposing a direct and independent communication method applicable between drones, it is expected that the shortcomings of WiFi or LTE communication methods used in drones so far can be supplemented."text-align: center;">

Meanwhile, these international standards are expected to be established as international standards around 2022 after going through frequency consultations with ICAO, ITU, etc.
