1 The basic composition and characteristics of 4G mobile communication technology

As China's urbanization process continues to advance, urban construction and population growth, social contradictions become increasingly complex and sharp, and the losses and impacts of various types of sudden-onset disasters and events are becoming more and more serious. The existing wired monitor

With the development and demand of the society, railways, highways, traffic tunnels, diversion tunnels, etc. have all been put into construction. In order to ensure the safe production of the construction and the normal dispatching command, the wireless communication system plays a vital role.The wi

Whether it's an office building, an airport, a shopping mall or a stadium, wireless networking has become a basic requirement for employees, customers and tenants. In the enterprise, the Portable Personal Equipment (BYOD) policy, which is designed to improve mobility and employee productivity, poses

DAS (Distributed Antenna System) is a network consisting of multiple antennas distributed in a building dedicated to providing wireless indoor coverage. DAS can solve the problem of high-end users' dense urban coverage, reduce the number and configuration of outdoor base stations, and reduce the ove

The Distributed Antenna System (DAS) is a network of multiple antennas distributed in a building dedicated to providing wireless indoor coverage. Such a system can be either an active system or a passive system.A passive DAS system is a network of coaxial cables, couplers, and power splitters. Passi

Many people have been looking forward to the advent of the 5G era, and may hope that a dream-like information technology revolution will bring a new way of life. An important feature of 5G mobile networks is that the signal transmission speed is fast; but in fact, 5G mobile networks have two importa

The PDT digital trunking wireless intercom system uses a large area system, and usually covers a large area with fewer base stations. However, in the city, due to the blockage of the building, the signal coverage of some regional cluster wireless intercom system is not ideal, especially in the area where the density of residential buildings is large, and the area of the handshake building is more, the coverage of the wireless intercom system is even worse.

Today's wireless communication systems use the most advanced digital technology and communication technology, featuring advanced technology, high spectrum rate and high data transmission rate, achieving the advantages of command and dispatch, telephone interconnection, data transmission and short me
