The Selection of Frequency Groups of Mine-used Wireless Communication System

More Information
  • On the basis of study of the effection factors for communication frequencies caused by underground geology condition and production condition, a relatively good frequency group of wireless communication transmission in underground was defined, and the distributing scheme of base-station in underground cellular communication was offered.
