Problems solved by technology

Due to the limited output power of the bidirectional amplifier, the supported passive network scale is small. If the power of the bidirectional amplifier is increased, the product cost will increase significantly, and the power consumption of the equipment will also increase significantly, making the backup power system cost of the equipment lower. Substantial increase
On the other hand, for such important coverage scenarios, there is currently a lack of monitoring of whether the antenna is connected normally
This poses a challenge to the reliability of distributed systems during bursty usage

Abstract

The invention discloses a public security wireless network coverage enhanced distribution system, which comprises a main control unit and a plurality of coverage units, and the input port of the maincontrol unit is connected with an information source output port, and the output port of the main control unit is connected with input ports of the plurality of coverage units through a passive distribution network; the main control unit comprises a coupler and a first active RFID module, the input port of the coupler is used as the input port of the main control unit, the output port of the coupler is used as the output port of the main control unit, and the coupling end of the coupler is connected with the first active RFID module; each coverage unit comprises a bidirectional amplification module, a second active RFID module and a coverage antenna; the input port of the bidirectional amplification module serves as the input port of the covering unit, the output port of the bidirectionalamplification module is connected with the input port of the covering antenna, and the second active RFID module is connected with the input port of the bidirectional amplification module. According to the invention, the signal coverage range can be improved, and more antenna access can be supported.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a public safety wireless network coverage enhanced distribution system. Background technique [0002] Public safety wireless networks refer to communication networks dedicated to firefighting and emergency response. It is used for special communication in fire alarm and other industries. In North America, it is mainly a P25 standard wireless communication network. In Asia Pacific and Europe, it is mainly a 800MHz trunking network. In many countries and regions, the coverage of such networks has some mandatory requirements. Due to the barrier of the building wall, the signal transmitted by the public safety wireless network base station is severely attenuated after entering the room, and the signal strength cannot meet the requirements for the indoor depth area. [0003] In order to solve this problem, a bidirectional amplifier (BDA) is generally used as ...
