Problems solved by technology
However, even with the support of 4G technology, due to factors such as the increase of indoor users, especially the increase of indoor data users, building shading and wall loss, and spectrum bandwidth and interference limitations, the single macro-cellular network deployment mode has become ineffective. It cannot meet the needs of users for high-speed seamless access

The invention relates to a system of covering signals by means of single cable transmission and the multiple input multiple output (MIMO) technique, and a networking method of covering the signals by means of the single cable transmission and the MIMO technique. The system comprises a near-end small cell group, near-end combiner units and far-end covering units. The near-end small cell group is used for receiving and sending communication signals capable of supporting MIMO networking. The near-end combiner units are used for combining the communication signals supported by the near-end small cell group and community antenna television (CATV) signals, and then the single cable transmission is achieved through CATV wire cables. The far-end covering units are used for shunting combining signals transmitted from the near-end combiner units, wherein the CATV signals are transmitted to the televisions through the CATV wire cables, and the remaining communication signals are output to MIMO antennas for signal coverage. According to the system of covering the signals by means of the single cable transmission and the MIMO technique, and the networking method of covering the signals by means of the single cable transmission and the MIMO technique, signal single cable transmission of the small cell group can be achieved by means of the existing CATV wire cables no matter whether signal frequency of a communication system supported by the small cell group is included in an frequency range occupied by the CATV signals or not, and the high-speed, high-quality and accurate signal coverage is achieved by means of the MIMO antennas of the plurality of far-end covering units at a far end.
Description
technical field [0001] The invention relates to the field of wireless communication signal coverage, in particular to a small base station (Small Cell) system and a networking method for signal coverage using co-cable transmission and MIMO technology. Background technique [0002] In recent years, the mobile wireless communication network has developed rapidly and continuously at a rate of updating every 10 years (or even shorter). With the rapid development of the mobile Internet, users put forward higher requirements on the data rate of mobile wireless communication networks, which further promotes the development and evolution of broadband mobile communication networks. In China, 3G has just entered a stage of rapid development, and large-scale 4G network trials have already begun. However, even with the support of 4G technology, due to factors such as the increase of indoor users, especially the increase of indoor data users, building shading and wall loss, and spectrum...
