Embodiment Construction

[0028] The wireless signal coverage system in the embodiment of the present invention is divided into an access mode using an active repeater and an access mode using a passive repeater.

[0029] Please refer to FIG. 1 , which is a schematic diagram of access to a wireless signal coverage system using an active repeater according to an embodiment of the present invention. The wireless signal coverage system of the embodiment of the present invention includes at least one repeater, splitter and combiner, active repeater, and cable television (CATV) passive distribution network. There is also an impedance converter between the repeater and the GSM port of the splitter. The cable TV dry amplifier is connected to the CATV port of the splitter through the CATV power splitter. The GSM&CATV port of the combiner is connected to the cable TV (CATV) passive distribution network. In each unit (room) of the building, one port of the home active repeater is connected to the CATV network u...

Abstract

This system includes a repeater station (RS), a splitter / combiner (SC), a CATV passive distribution network (PDN) and an active relay (AR). Via CATV power divider, CATV main amplifier connects to one end of SC. RS receives the mobile communication signal (MCS) and transfers it to the other end of SC. SC mixes MCS with the CATV signal and transmits the mixed signal to AR through PDN. The mentioned AR includes a SC, a bidirectional amplifier and an antenna. One end of SC orderly connects to the bidirectional amplifier and the antenna. The beneficial effect of this invention is: it solves the problem that the coverage of mobile communication signal is poor inside buildings.

Description

technical field [0001] The invention relates to a signal coverage system, in particular to a wireless signal coverage system. Background technique [0002] After years of engineering construction for mobile communication GSM network, the network scale and services have been basically formed. At the same time, with the development of a large number of network optimization projects, areas with blind spots in the past, such as villages, expressways, bridges, tunnels, and urban office buildings, have basically been obtained. Good coverage, the entire network indicators have been significantly optimized. [0003] The indoor coverage project carried out in the past two years has made network coverage a new goal. The improvement of network quality also makes customers have higher and higher requirements for voice, especially the signal quality in residential areas is particularly concerned. For large residential quarters, although most of them have built indoor coverage systems, ...
