由中继器、组合器、分配器、双工器、射频电缆、室内全向天线。 The multi-channel digital trunking wireless intercom system consists of repeaters, combiners, distributors, duplexers, radio frequency cables, and indoor omnidirectional antennas. Original digital conventional repeaters can be upgraded to advanced repeaters through software. The digital repeater TX and RX terminals are connected to the combiner and splitter through RF cables, respectively, and the combiner output (ANT) and splitter output (ANT) are connected to the duplexer through RF cables. At the end and low end, the ANT terminal of the duplexer is connected to the arrester and the outdoor antenna through an RF cable. The interface of the digital repeater backplane is connected to the network switch using an Ethernet cable.
This digital trunking wireless intercom system is based on a large-area distributed networking model. The core network uses an all-IP softswitch architecture. The system equipment adopts the modular design concept, and the spectrum utilization rate is as fast as the link speed. Wide coverage, system group. The network is flexible, the network construction and maintenance costs are low, the reliability is high, the reliability is high, and the scalability is good. It can provide flexible and diverse networking forms according to the specific requirements of users.
Digital trunking wireless intercom system is a professional communication scheduling management system based on IP network. Through the server, multiple time-division digital trunking sites (single base stations, multiple base stations, etc.) distributed in different places are connected together through the IP network to realize voice data. Joint distribution and synchronization.
According to the different requirements of users, the multi-channel wireless intercom system can establish single-area multi-base stations, multi-zone multi-base stations and other regional networks or networks of different scales nationwide to meet public safety requirements. The army's frontier armed police, administrative law enforcement, railways, water conservancy, and professional wireless communications require mid- to high-end users such as forestry.
