Description
Technical Field
The invention relates to the field of wireless communication, in particular to a far-end device of a multi-band signal receiving and transmitting system, the multi-band signal receiving and transmitting system and a power consumption metering method.
Background
The mobile communication technology rapidly evolves from 1G to 4G applied in a large scale, so that the development of subsequent 5G and 6G drives the explosive growth of broadband data services such as mobile internet, internet of things and the like, the coverage of signals of different systems is particularly important when the indoor mobile communication technology is used as a main occurrence area of the data services, and meanwhile, due to the coexistence of signals of multiple systems such as 2G, 3G, 4G and 5G and 6G, great challenges are brought to the traditional network coverage and optimization. Traditionally, the first mode of the indoor coverage system is to use the existing single-band optical fiber repeater equipment and use multiple pieces of equipment in a multi-band coverage cell, which results in increased cost and installation complexity. The second method is a coverage method of BBU + RRU, since RRU basically can only support a single frequency band and cannot meet the requirement of multiple frequency bands, and since the information source used in the coverage area may not be the same host equipment manufacturer, BBU cannot be used, thereby affecting the implementation of the overall coverage scheme. The third mode is a micropower indoor distribution system of the access unit, the expansion unit and the radio frequency unit which are adopted at present, but the requirements of large capacity and large bandwidth of 5G cannot be met due to the limitation of the access unit architecture and bandwidth factors. The fourth mode is to adopt a multi-band system product, which can well meet the requirements of high capacity and large bandwidth of multi-band coexistence, but because multiple frequency bands are fused in one system, the power consumption of a single device cannot be counted, which brings great difficulty to the maintenance of each subsequent operator, and especially when multiple operators in a single frequency band apply, the problem is more prominent. However, no solution has been proposed by manufacturers in any of the published documents so far, which further limits the application of the multiband system in indoor coverage scenarios.
