Problems solved by technology

[0005] However, in a system connected to multiple remote machines, if the near-end machine fails, the entire system may be paralyzed, causing serious impact on the signal coverage area.
Moreover, if the failure of the near-end unit exceeds the ability of the near-end unit to repair itself, the above-mentioned technical problem cannot be solved by learning the method disclosed in the above-mentioned patent application. It will not be able to communicate wirelessly with the outside world, and for particularly important signal coverage areas, it may cause serious losses; moreover, it will take time, manpower and material resources to send maintenance personnel to the site for maintenance

Abstract

The invention discloses a remote radio system which can ensure the normal work of a communication system when a proximal machine fails and a proximal device thereof. The remote radio system comprises the proximal device and a remote device, wherein the proximal device comprises a main proximal machine, a backup proximal machine and a switching control machine; the switching control machine comprises a switching unit and a monitoring unit which are mutually connected; signal channels of the main proximal machine, the backup proximal machine and the remote machine are respectively connected with the switching unit of the switching control machine; and the monitoring unit of the switching control machine is connected with the main proximal machine, is used for monitoring whether the main proximal machine fails, and controlling the switching unit to switch a route of communication signals to a signal link between the backup proximal machine and the remote machine from the signal link between the main proximal machine and the remote machine.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a radio remote system and its near-end equipment. Background technique [0002] Due to the propagation characteristics of radio frequency signals and the occlusion of artificial or natural objects, the coverage area of ​​wireless communication often has blind spots and weak signal areas. These areas are prone to phenomena such as low connection rate, poor roaming, dropped calls or even no signal reception. , causing inconvenience to mobile phone users. The digital remote radio system is a relay product that can effectively solve such problems. [0003] The digital radio remote system is a software-based radio technology, which digitizes the radio frequency signal, processes and transmits the signal in the digital domain, and has the characteristics of star, daisy chain and hybrid networking. Remote machine connection is widely used in 3G mobile. Compared with 2G ...
