More introduction:
Multipoint is a dial-up client based on campus network authentication developed by Guangzhou Hotspot Software Co., Ltd. ("Urban Hotspot" for short). The campus network is automatically identified, and it is fast and convenient to access the Internet, and the online time and traffic are clear at a glance. It has covered two mainstream platforms, Android and IOS.
Expand knowledge:
The fifth generation mobile communication technology (5G for short) is a new generation broadband mobile communication technology, which has the characteristics of high speed, low delay and large connection, and is the network infrastructure to realize man-machine interconnection.
The International Telecommunication Union (ITU) has defined three major application scenarios of 5G, namely, Enhanced Mobile Broadband (eMBB), Ultra-high Reliability and Low Delay Communication (uRLLC) and Mass Machine Communication (mMTC).
Enhanced Mobile Broadband (eMBB) mainly aims at the explosive growth of mobile Internet traffic, and provides a more extreme application experience for mobile Internet users. Ultra-high-reliability and low-delay communication (uRLLC) is mainly used in vertical industries that require high delay and reliability, such as industrial control, telemedicine and autonomous driving. Mass machine communication (mMTC) is mainly aimed at smart city, smart home, environmental monitoring and other application requirements for sensing and data acquisition.
In order to meet the diverse application scenarios of 5G, the key performance indicators of 5G are more diversified. ITU defines eight key performance indicators of 5G, among which high speed, low delay and large connection are the most prominent features of 5G. The user experience rate reaches 1 Gbps, the delay is as low as 1 ms, and the user connection capacity reaches 1 10,000 connections /km2.
Since the opening of the first 5G test site in Shenzhen in June 20 17, the development of 5G industrial chain has made rapid progress.
20 18 June, 3GPP released the first 5G standard (Release- 15), which supports 5G independent networking and focuses on enhancing mobile broadband services. In June 2020, the Release- 16 version standard was released, focusing on supporting low-latency and high-reliability services, and realizing support for applications such as 5G car networking and industrial Internet. The Release- 17(R 17) version of the standard will focus on realizing differentiated IOT applications and realizing medium and high-speed Dalian connection, and it is planned to be released in June 2022.
