What’s the difference between 4G and 5G?

4G mobile networks have now entered a stage of rapid popularization, and at the same time, 5G standards have begun to emerge. So what is the difference between 4g and 5g networks?

What's the difference between 4G and 5G

First of all, the biggest difference is the network speed. It is currently estimated that the fastest 5G network can reach 10G/s, which is 10 times faster than 4G. That is to say, when using 5G network, we can download in a few seconds for a high-definition movie,


4G and previous mobile networks mainly focus on the provision of raw bandwidth, while 5G aims to provide ubiquitous connections and lay the foundation for fast and flexible network connections, regardless of whether the user is in a skyscraper or a subway station.Of course this is also the same as the development of the Internet of things is inseparable, and the Internet of everything will also be realized in the 5G network environment.

The 5G network will not exist independently. It will be a combination of multiple technologies, including 2G, 3G, LTE, LTE-A, Wi-Fi, M2M, and so on. In other words, the original intention of 5G is to support a variety of different applications, such as the Internet of Things, connected wearable devices, augmented reality, and immersive games.

The 5G network will be the first to use new architectures such as cloud RAN and virtual RAN to promote the establishment of a more centralized network and maximize the use of server farms through localized data centers at the edge of the network.

5G will also take the lead in using cognitive radio technology to allow the network infrastructure to automatically determine the type of frequency band to provide, distinguish between mobile and fixed equipment, and adapt to the current situation within a specific time.

Although 5G is superior to 4G in terms of transmission speed, bandwidth, and accessible equipment, its base station propagation attenuation and base station construction costs will also be higher.

What are the advantages of 5G?

5G is the fifth generation of cellular mobile communications. The performance goals of 5G are high data rates, reduced delays, energy savings, cost reductions, increased system capacity and large-scale device connections.

What are the advantages of 5G

High speed

The data transmission rate of the 5G network is much higher than the previous cellular network, up to 10 Gbit/s, which is 100 times faster than the previous 4G LTE cellular network. With the ultra-large bandwidth transmission capability of 5G, even watching 4K high-definition video, 360-degree panoramic video, and VR virtual reality experience will not be stuck.


Low latency

One of the goals of each generation of wireless products is to reduce waiting time. The new 5G network will have a delay compared to 4G LTE transmission, and the data transmission will take less than 5 minutes. . This feature shows that 5G networks have great applications in telemedicine operations, unmanned driving, automatic industrialization and other fields. During the new coronavirus epidemic, we can grasp that 5G has played a significant role in global epidemic information sharing, prevention and control.


Internet of Everything

The Internet of Things is the main driving force for the development of 5G, and the industry believes that 5G is designed for the Internet of Everything. From the perspective of demand level, the Internet of Things first meets the needs for identification of items and information reading, and secondly, the transmission and sharing of this information through the network, and then the system management and information data brought by the increase in the magnitude of the networked objects analyze, and finally change the business model of the enterprise and people’s life mode to realize the Internet of Everything.


Ubiquitous Network

With the development of services, network services need to be all-encompassing and widespread. Only in this way can we support richer services and can be used in complex scenarios. The ubiquitous network provides influence at two levels: wide coverage and deep coverage. To a certain extent, the ubiquitous network is more important than high speed. Just building a very high-speed network with a small number of places does not guarantee the service and experience of 5G, and the ubiquitous network is a fundamental guarantee for the 5G experience.

What impact will 5G technology have on AGV

In many automated factories, AGV plays an important role in the production process, so what changes will the 5g network bring to the factory?

What impact will 5G technology have on AGV

1. Strengthen logistics cooperation GV small workshop

As we all know, the communication of logistics AGV vehicles relies on network support. The emergence of 5g guarantees the high-speed communication of AGV trolleys and enables AGV trolleys to have the level of self-organization and collaboration. According to the scheduled tasks, AGV vehicles can cooperate with each other to complete tasks that a single AGV vehicle cannot complete.

2. The use of 5g logistics AGV vehicles has the characteristics of safety, reliability, and ultra-low delay. It can more timely perceive the behavior of employees, be sensitive and coordinated, maintain a safe distance, and ensure the safety of the vehicle and its materials.

3. AGV car real-time control

For some special environments where high temperature and high pressure are not suitable for manual entry, the staff can use the 5G network to remotely control the AGV trolley through the monitoring platform in real time, and complete the set work plan safely and reliably.

4. Real-time collection and analysis of AGV data

Through the low-latency characteristics of the 5g network, a large number of AGV automotive logistics equipment and important parts can be interconnected in the factory, which improves the timeliness of production and manufacturing data collection, and provides strong network data support for production and manufacturing business processes and energy consumption management. Through the production log generated by the logistics AGV, employees can understand the time, location and trajectory of logistics operations.

In the future, 5g networks will vigorously develop applications in this field and realize real-time management of production equipment, which will trigger a new industrial revolution.
