Anonymous users2024-02-06Radio plays an important role in our lives, first of all, it should be said that it is radio communication, that our daily most common mobile phone is the most popular radio communication, this network system composed of mobile phones, base stations, switching terminals and other equipment greatly facilitates our lives, followed by private network communication, in fact, CDMA was first developed for the army, this system has the characteristics of good confidentiality, signal stability, etc., most of the communications used by the army now have frequency hopping technology, That is, several parties to the communication can switch frequencies at any time according to certain rules, so that they are less likely to be intercepted. Now when it comes to radio communication, most of them refer to radio communication, such as in disasters, when the base station or switching system can not work, radio communication can play its advantage of not relying on network communication, in emergency communication can be said that radio communication has an irreplaceable role, this means of communication is also widely used in armed police, fire protection, forestry departments, etc., and amateur radio amateurs are also one of the users of this communication. Then there's satellite communication, which we see now is transmitted through satellite signals, and when astronauts talk to ground crews, it's also a kind of radio communication.
Another important area is radio control, when we easily hold the remote control at home to change the electric channel, we must experience the huge role of radio control, when many special industries and ordinary industrial production, based on radio control automation is more and more popular, rocket liftoff, explosive disposal robots, deep-sea exploration, and radioactive waste disposal and so on Radio control is essential.
There is also radiolocation, when we need to locate a place with complex terrain, we need to use radiolocation technology, which has been widely used by rescue agencies, maritime departments, and outdoor enthusiasts.
There is also radio remote sensing, in fact, radio is a way to transmit signals, with the development of radio, it will be more convenient for our lives in the future.
I kind of wrote about it, and I'm expanding on it, and I'm adding some of my own opinions.
