Microwave applications of those frequencies?

A: Because microwave applications are extremely wide, especially in the field of communications, in order to avoid interference between each other, the International Radio Regulations Commission has made specific provisions for the division of frequencies. Divided into industrial, scientific and medical frequencies are 433 MHz, 915 MHz, 2450 MHz, 5800 MHz, 22125 MHz, and communication frequencies used separately. Currently, the common frequencies used for industrial heating in China are 915 MHz and 2450 MHz. Microwave frequency and power selection can be based on the shape of the heated material, material, moisture content of different.
