Abstract

An embodiment of the invention provides a broadband distributed antenna system and a data communication method and relates to the technical field of networks. A remote hub is in data communication with remote access units in a free space communication mode. Compared with the mode that all devices in an existing broadband distributed antenna system are connected by laying optical fibers, cables and the like, the data communication method can shorten mounting time and save wiring cost. Additionally, the remote hub and each remote access unit are connected and configured flexibly so as to facilitate technological upgrading and adjustment.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a broadband distributed antenna system and a data communication method. Background technique [0002] Distributed Antenna System (DAS: Distributed Antenna System) is a network composed of multiple antennas distributed in a certain building and dedicated to providing wireless indoor coverage. The DAS system provides operators with a more effective indoor coverage solution than small, distributed indoor base stations. [0003] Wideband Distributed Antenna Systems (DAS) have recently attracted a lot of attention because of their ability to distribute signals across multiple frequency bands to end users using a unified, protocol-independent fiber optic platform. [0004] Existing broadband distributed antenna systems generally include a main hub, remote hubs and remote access units, which are usually connected by laying multiple optical fibers or cables. [0005] In the process of...
