Abstract

The invention relates to a mobile communication micropower digital multipoint indoor coverage system, including a multimode signal access unit, an expansion unit and a far-end unit. The multimode signal access unit adopts an optical fiber as a transmission medium to transmit a signal into the expansion unit, the expansion unit uses a category-5 cable or an optical fiber to transmit the signal into the far-end unit; the multimode signal access unit can be connected with eight expansion units at most, one expansion unit can be cascaded with another expansion unit, and one expansion unit can be connected with eight far-end units at most. The mobile communication micropower digital multipoint indoor coverage system provided by the invention realizes multi-system (2G/3G/4G/WLAN) signal integrated coverage, solves the problem of repeated construction of multiple networks, and has good expansibility; communication noise is greatly reduced through a digital signal processing algorithm, and transmitted power of a radio frequency signal is only 27dBm, which is environment-friendly; the device is small in size, can determine installation density according to actual needs, is low in installation cost and small in construction difficulty, and is suitable for occasions with a large signal demand quantity and special demands such as communities, elevators, public venues, basements, hospitals and so on.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a mobile communication micro-power digital multi-point indoor coverage system suitable for occasions with large and special demand for signals such as communities, elevators, public venues, basements, and hospitals. Background technique [0002] With the continuous development of mobile communication technology, mobile services are becoming more and more abundant, and the number of users is rapidly expanding. According to the latest statistical bulletin released by the Ministry of Industry and Information Technology, by the end of 2012, my country's mobile phone users had exceeded 1.112 billion, and the penetration rate reached 82.6 units / 100 people, exceeding the global average level. Among them, 3G mobile communication users will reach 200 million. Calculated according to the population base of our country, mobile phone users and 3G mobile communication users will ...
