How to replace the traditional optical cable in smart substation by wireless transmission

Microwave, microwave is a communication transmission mode that has been eliminated. A long time ago, all provinces had independent microwave stations, which were only responsible for transmission. The end user is the post office. Later, after the optical cable appeared, the microwave station gradually withdrew from the communication transmission stage. At present, some communication base stations can't reach the optical cable line for various reasons, and operators also use microwave transmission instead of optical cable transmission. Microwave equipment is reserved in all provinces, that is to say, as long as operators are willing, they can build base stations anywhere.
