Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a wireless communication system based on Ethernet all-digital signal transmission. Background technique [0002] In the post-4G era, the construction of operators' 4G macro stations has been basically completed, and the coverage is gradually developing from outdoor to indoor. In the future, the investment in indoor LTE deep coverage will continue to increase. However, the traditional MDAS solution has the problems of complex design, small coverage, and RF signals are easily blocked by indoor walls. However, due to design problems, the traditional room division scheme has the disadvantages of property coordination and difficult maintenance after construction. Therefore, the traditional room division scheme is bound to be gradually replaced by the new active room division. How the new active indoor distribution system can solve the shortcomings of the tradition...
