Asymmetric single-double current hybrid indoor coverage system

Abstract

The invention relates to an asymmetric single-double current hybrid indoor coverage system. The system comprises an LTE base station remote radio unit, near-end equipment and an active antenna which are in two-way transmission connection. The LTE base station remote radio unit is provided with a double current downlink signal outputting function and a single-double current uplink signal receiving function at the same time, downlink signals are output through the active antenna, and the uplink signals are received through the active antenna. The near-end equipment comprises frequency conversion equipment and a combiner. Output ends of the LTE base station remote radio unit are connected with input ends of the frequency conversion equipment and the combiner, and an output end of the frequency conversion equipment is connected with an input end of the combiner. The active antenna is provided with frequency conversion and power detection functions. An output end of the combiner is connected with an input end of the active antenna. The system has the advantages that the used active antenna is capable of carrying out power detection and calculating the monitoring the loss condition of each feeder cable in real time, so that the problem that a service provider fails to monitor indoor feeder cables in real time is solved.

[0002] In the fourth-generation mobile communication LTE system and wireless local area network system based on MIMO technology, communication equipment usually outputs dual-stream signals of the same frequency. A new feeder cable is laid, but the construction cost of laying a new feeder cable is high, property coordination is difficult, and it is even impossible to enter the site for construction in some communities; secondly, whether it is the existing single-cable indoor coverage In the system, many passive components such as power splitters, RF feeder cables, and couplers are used between the radio remote unit of the base station and the antenna. The aging and damage of these components cause some antennas to fail to work, but operators cannot monitor these components in real time. The state of the topological network composed of passive devices can only be monitored by regularly sending personnel to inspect the power state of the antenna port, so as to ensure the smooth operation of the antenna, which has become a great burden for operators; The coverage of a single antenna is small, and the number of antennas carried by a single remote radio unit of a base station is limited, so the cost of dual-stream coverage is high
