一、Definition and background
Definition: 5G-R is a 5G technology specially designed for the railway transportation industry, which belongs to the Private Network communication system and is completely independent and isolated from the Public Network communication systems of mobile, telecom, Unicom and other operators connected to the Internet by passengers.
Background: With the development of high-speed railway and the increasing demand of railway wireless system for Internet of Things, video surveillance and other services, the traditional GSM-R system based on 2G technology has been unable to meet the development needs of modern railway. Therefore, 5G-R, as a more advanced communication technology, came into being to promote the high-quality development of railway communications.Wireless Router
二、Second, technical characteristics
Super bandwidth: 5G-R is based on 5G technology, has the characteristics of super bandwidth, and can carry the communication bandwidth demand after the digital transformation of railway.5G Industrial Router
Ultra-low delay: The ultra-low delay feature of 5G-R is crucial to ensure railway running safety, and can support real-time communication of key services such as train control and command scheduling.
Massive connections: 5G-R supports massive connections and can meet the communication needs of many devices and systems along the railway.industrial wifi router factories
Network slicing and edge computing: 5G-R supports services such as network slicing and edge computing, which can provide service quality assurance for key railway services and improve the safety and efficiency of railway operation.
三、 Application scenarios
Train control: The 5G-R system can carry core services such as train control for future railways, especially high-speed railways, to ensure safe and smooth train operation.
Command and dispatch communication: 5G-R supports railway command and dispatch communication to achieve real-time communication and information sharing between trains and dispatch centers.
Internet of Things and video surveillance: With the increase of business needs such as the Internet of Things and video surveillance, 5G-R can provide stable communication support to meet the needs of railway informatization, digitalization and intelligence.industrial wifi router factory
四、 development status and future trend
Development status: At present, the working frequency band of 5G-R in China is 2100MHz, specifically for uplink 1965MHz-1975MHz, downlink 2155MHz-2165MHz, each 10MHz, using FDD system. The Ministry of Industry and Information Technology has approved the test frequency of the new generation of railway mobile communication system (5G-R) based on 5G technology to China National Railway Group Co., Ltd. to support its field technology test of 5G-R system.
Future trend: It is expected that by 2030, 5G-R will realize the replacement of GSM-R and become the mainstream technology of railway wireless communication system. With the deployment of 5G-R network and the expansion of application scenarios, the railway industry will usher in a new era of more intelligent and efficient.industrial wifi router manufacturer
