Problems solved by technology

For example, when there are multiple frequency bands or signals from multiple operators, the wireless coverage of the system is poor, or even does not support signal input from multiple frequency bands or multiple operators
In addition, the bandwidth of the current system affects the transmission rate, and it also has the defects of high cost and inflexible design combination

Abstract

Embodiments of the present disclosure provide a distributed antenna system. The distributed antenna system includes: multiple ports configured to receive downlink signals or send out uplink signals; multiple first antennas configured to send out downlink signals or receive uplink signals; a power adjustment unit coupled to the multiple ports and multiple Between two first antennas, and configured to transmit and adjust downlink signals or uplink signals, the power adjustment unit includes: a plurality of first links, respectively corresponding to different frequency bands; and a first power adjustment unit, configured to pair The power of link signals transmitted on each first link is adjusted so that the powers of link signals of different frequency bands transmitted on multiple first links are substantially the same. The solution disclosed in the present disclosure can support signal input of multiple frequency bands, realize power balance, and improve system performance and wireless coverage effect.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and more particularly, to a distributed antenna system. Background technique [0002] Indoor wireless signal coverage refers to the coverage method for indoor places such as residential buildings, subways, airports, stadiums, hotels, and shopping mall complexes. With the popularization of the fifth-generation mobile communication technology (5G), about 85% of business traffic will occur in indoor scenarios, and the quality of indoor wireless signal coverage is directly related to the experience of 5G indoor applications. However, due to the low penetration of 5G millimeter wave in space transmission and its susceptibility to interference, as well as the many obstacles in indoor places, strong interference and complex environment, the indoor coverage of outdoor base stations is less effective. For this purpose, a mobile communication network called a distributed antenna system can b...
