Around us, we often see some drones controlled by photographers hovering over us. Come and go freely, the flight is very stable. The aerial photography of drones is increasingly favored by modern people. So what technology does the drone rely on for wireless transmission? Today, Xiaobian will explain it to everyone.
In fact, the types of drones are divided into a variety of types, military, public, civilian, police, etc., also because of the large range of flight of the drone, the reason for the random change of the flight place, the way of wired transmission can not be achieved, therefore, wireless transmission of signals Technology has become the only way to control drones.
Recently, the rapid development of drones has also been restricted by technical factors, such as the high-speed flight of no one to transmit clear and stable images, which have become the bottleneck of the development of drone technology. In response to this situation, our company has developed a series of wireless mobile video transmission products. The system uses advanced COFDM full digital modulation and demodulation technology and MPEG2/MPEG4 digital compression coding technology, and its multi-carrier and other technical features, anti-multiple Strong track capability, "non-line-of-sight", "diffractive" transmission characteristics and good penetrating ability, can meet the wireless communication task of the drone, COFMD technology uses 1.2GHz low-frequency microwave signal transmission on the drone. The use of this frequency not only increases the transmission rate of the drone signal, but also ensures a stable transmission effect over a long range of transmission.
Now with the application of COFDM technology, UAV signal transmission has been widely used in aerial reconnaissance, air security, rescue and disaster relief, environmental detection, fire control, power inspection and other fields, and has been well received by users. It is believed that with the further development of transmission technology, drones will have a greater role in the future.
