5G is a new generation of broadband mobile communication technology characterized by high speed, low latency and large connectivity. 5G system is based on large bandwidth and large-scale antenna scheme, which can realize sub-meter high precision positioning.

According to the "5G Economic and Social Impact White Paper", according to the 5G large-scale commercialization only in 2020, it is expected that during the period from 2020 to 2025, China's 5G development will directly drive the total economic output of 10.6 trillion yuan, directly create economic added value of 3.3 trillion yuan, and create direct employment of 3.1 million jobs. In this era of Internet of Everything, more and more countries and regions attach great importance to 5G technology and regard it as the cornerstone of information economy.

Application Scenarios of 5G Technology

The international standardization organization 3GPP has defined three major directions for 5G application scenarios, including enhanced mobile broadband (eMBB), ultra-high reliable low-latency communication (uRLLC), and massive machine communication (mMTC).

1. Enhanced Mobile Broadband (eMBB)

Based on the existing mobile broadband service scenarios, eMBB optimizes the communication experience between people by providing access with higher experience rate and larger bandwidth. In this scenario, the user experience rate can reach 100Mbps to 1Gbps (the maximum experience rate of 4G is 10Mbps), and the peak speed can reach 10 to 20Gbps. eMBB scenarios are mainly oriented to high-traffic mobile broadband services, such as 3D/4K/8K ultra-high-definition video, AR/VR, cloud work/entertainment, and 5G mobile terminals.

2. Ultra-high reliable low-latency communication (uRLLC)

The uRLLC application scenario provides low-latency and high-reliability information interaction capability, supporting highly real-time, precise and secure business collaboration among interconnected objects. In this scenario, the end-to-end latency is at the level of ms (e.g., the latency of industrial automation control is about 10 ms; the latency of unmanned driver transmission is as low as 1 ms), and the reliability is close to 100%. uRLLC scenarios are mainly oriented to the business of industrial automation, Telematics, unmanned driver, remote manufacturing, and telemedicine.

3. Massive Machine Class Communication (mMTC)

The mMTC application scenario is mainly the information exchange between people and things, which supports the efficient access and management of large-scale, low-cost and low-consumption IoT devices by providing optimized signaling control capability at high connection density. In this scenario, the density of connected devices is 1 million devices connected per square kilometer, and the service life of mid-range batteries reaches 15 years. mMTC scenarios are mainly oriented to smart cities, smart homes, and smart manufacturing.

Development trend of 5G technology

According to the actual situation, the future 5G communication technology can develop in two directions, one is the Internet aspect, and the other is in the Internet of Things, which is committed to solving the massive communication problems existing in the existing machinery.

On the one hand, with the development of Internet technology, 5G network communication is also in the rapid development and improvement, and Internet technology will also become the platform for the development of future network communication technology. For our country, 5G mobile communication technology has been in a backward state. In order to realize the better development of technology, in the new round of 5G communication competition, China has launched a research group specializing in 5G mobile communication technology to promote the better development of technology.

On the other hand, the development of mobile Internet technology also provides a better research basis for the development of 5G mobile communication system, so that the 5G mobile communication network has a higher quality transmission and system efficiency technology. In terms of wireless transmission, 5G communication technology expands the width of wireless mobile communication, resulting in a further improvement in communication frequency. And compared with the traditional 2G, 3G, 4G mobile communication technology, 5G mobile communication is more humanized in terms of user experience, which can give users a better use experience. Under the influence of the new 5G communication technology, the wireless signal coverage is higher, realizing better indoor mobile signal communication.

5G+BeiDou: Open up a huge space for intelligent security

Driven by domestic substitution, favorable policies, the rise of technology cycle and demand, the application of 5G+BeiDou positioning system in the fields of smart city, public security, industrial and agricultural machinery, unmanned systems and so on will be further deepened, and the space for industrialization development will be further expanded. In traditional fields, 5G+BeiDou high-precision positioning can be used in engineering construction, surveying and mapping, environmental monitoring, dock loading and unloading, airport scheduling and other fields; in emerging fields, automatic driving, intelligent transportation, intelligent logistics, precision agriculture, unmanned aerial vehicles, cell phone high-precision positioning, and other BeiDou convergence and innovation applications are developing rapidly.

JUNODA 5G+BeiDou RTK fusion positioning system adopts BeiDou RTK differential positioning, GIS, combined with 5G network communication, using positioning base station, positioning tags and other equipment to provide global position display, real-time track tracking, historical data playback and positioning monitoring and analysis, etc., to provide enterprises with seamless indoor and outdoor positioning, and comprehensively guard the safety of personnel in the production site.

As a new generation of information technology, the fusion of 5G and Beidou can realize the integration of heaven and earth, communication and guidance, and promote the intelligent connection of everything and precise cooperation, which will become an indispensable and important support for the new infrastructure to move towards digitization, intelligence, and realize the upgrading and transformation.
