Problems solved by technology

[0004] For newly built buildings, the independent transmission of multiple signals can be achieved by laying multiple feeder cables, but the construction period is long, the investment cost is high, and there are special problems in the construction process that the installation of multiple feeder cables is limited; In the distribution system building, there is only one feeder cable in the indoor distribution system, which cannot support MIMO multi-channel signals. If other feeder cables are installed, it will face many problems such as re-construction and high investment costs.

Abstract

The present invention relates to the technical field of mobile communications. Provided are an indoor distribution system, a local unit and a remote unit designed to realize high-speed transmission of multipath signals while saving resources and avoiding the power supply difficulty of a remote unit. The indoor distribution system comprises a local unit (11) and a remote unit (12) connected via a single feeder cable; the local unit (11) comprises a local mixing part (111), and the remote unit (12) comprises a remote mixing part (121), the remote mixing part (121) being a passive component. The present invention is suitable for the network structure of mobile communication.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an indoor distribution system, a near-end machine and a remote machine. Background technique [0002] Communication technology is changing with each passing day. With the continuous development of data communication and multimedia service requirements, it integrates 3G (3rd-generation, third-generation mobile communication technology) and WLAN (Wireless Local Area Networks, wireless local area network) and can transmit high-quality Video images, and the fourth-generation mobile communication and its technology (4th-generation, 4G), whose image transmission quality is comparable to that of high-definition television, has begun to rise. Many countries and regions adopt LTE (Long Term Evolution, long-term evolution) technology as a 4G standard. [0003] The MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) technology can be introduced into the indoo...
