In terms of fighter formation communications, it is called "机间数据链" in Chinese. The U.S. military calls it IFDL. At the same time, the US military uses TTNT to achieve communication between fighters, early warning aircraft, warships and other different equipment.
These are all data links at the tactical level. It can achieve safe and stable data transmission with low latency and high speed. But they have a shorter transmission distance.
NATO uses Link 16/22 for wider data links. They are like the difference between a LAN and the internet.
Military communications and civilian communications, the underlying communication logic is completely identical. There are very big differences between them in terms of data encryption, anti-interference ability, data stability and other applications. A few decades ago, military communications were completely ahead of civilian communications, and now they are integrated with each other, and in the future civilian communications will be ahead of military communications.
The U.S. military began to cooperate with Starlink. Huawei communicates with high-orbit satellites on mobile phones and long-distance underwater communications.............. These are examples of how civilian communications technology is increasingly leading military communications.
The development of technology requires not only talents, but also a platform for development. These advanced communication theories and technologies require a large enough platform to verify and promote. It makes no sense to just stay in the theoretical stage and in the laboratory. Some developed countries in Europe have very good communication technology talents, however, their countries cannot provide a platform for them to play.
When it comes to military communications technology, it is highly classified by various countries. They do not easily open up data communication protocols and data communication interfaces. When they sell weapons, they only open up some data communication interfaces to a limited extent, and when they use these data communication interfaces to communicate with other weapon systems, they cannot fully exploit the capabilities of these weapons.
With years of in-depth research on the Sukhoi system, China was able to crack the Su-35's communication system and achieve complete data communication between the Su-35 and other Chinese fighters. This provoked protests from Sukhoi, which, of course, were private.
I'm sure my friends in India will have some difficulty accepting it.
We can observe when India will achieve "A shooting, B guidance" between LCA and Rafale. When India announced the news, we believed India had TTNT-like capabilities. If it's just some analytical article in the form of slogans, it doesn't make any sense.
