Indoor coverage system

Abstract

The invention provides an indoor coverage system. The system comprises a baseband backup unit (BBU), a radio remote unit (RRU), a proximal control unit, an expansion unit, a remote access unit, a power divider, a coupler, a feeder cable, a connector and an antenna, wherein the BBU is connected with the RRU through an optical fiber; the RRU is connected with the proximal control unit through an optical fiber; the proximal control unit is connected with the extension unit through an optical cable; the expansion unit is connected with the remote access unit through an optoelectronic composite cable; output ports of the power divider and the coupler are connected with the feeder cable; the feeder cable is laid indoors and outdoors; an indoor antenna is fixed to the feeder cable and close to anindoor user; and an outdoor antenna is fixed to a roof and outdoor wall. Thus, a wireless network forms best coverage indoors; an indoor user can absorb more traffics; and the utilization rate of wireless network resources is increased.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a novel indoor and outdoor coverage system. Background technique [0002] Indoor mobile accounts for about 70% of the entire mobile network business. Indoor signal quality has become a key factor for operators to gain a competitive advantage. As an effective supplementary coverage for outdoor macro stations, the indoor distribution system is aimed at indoor user groups and mainly solves problems in buildings. The network coverage of the mobile communication network, the scheme of network capacity and network quality, and the distribution design of the indoor antenna feeder system are one of the main factors affecting the quality of indoor communication. Therefore, the design of the indoor coverage scheme is very important to improve network performance. [0003] In traditional room distribution system antenna design, it is usually chosen to install a di...

AI Technical Summary

Problems solved by technology

[0009] Due to the structure of the house and other reasons, the antenna is usually placed on the outer wall of the owner's door. The traditional coverage solution has a large feeder loss, and it is difficult to balance the output power of the antenna port, resulting in low power at the end antenna port, causing indoor coverage blind spots, and users cannot effectively use mobile phones. business

Reduce the utilization of mobile network resources and reduce user perception

At the same time, if figure 1 , 2 As shown, many existing indoor coverage systems have been covered by RRU and BBU equipment, which improves the signal strength of the indoor mobile network. However, due to the large number of RRU and BBU equipment used, such as figure 1 , 2 Among them, 6 buildings use 6 RRU devices, and the cost of the large number of RRUs leads to high overall cost of networking in the community
