Microwave communication Microwaves often refer to electromagnetic waves whose frequencies are above 1000 megahertz (MHz) (wavelengths below 30 cm). Communications using microwave propagation are called microwave communications.
The propagation characteristics of microwaves are similar to those of light propagation. They generally propagate along a straight line. The diffraction ability is very weak. Generally, communication within the line of sight is performed. For long-distance communication, relaying can be adopted. For microwave relay communication, or microwave relay communication It is also possible to use tropospheric propagation for communication, called troposcatter communication, or to use artificial satellites for relaying, that is, satellite communication.
The characteristics of microwave communication are: 1. Wide band range and large communication capacity, so microwave communication is generally multi-path communication; 2. Communication is relatively stable.
Due to the poor diffraction performance of microwave products, all wireless monitoring equipment must ensure transmission in an open environment to ensure signal stability. Specific program design, please consult professional and technical personnel!
