What is 5G LAN?

Dec 08, 2022

Following the metaverse trend, there is another hot word sweeping the Internet of Things business circle recently - 5G LAN.

In the 5G era, under the impetus of "4G changes life, 5G changes society", 5G shoulders the mission of "connecting everything and helping digital transformation of thousands of industries", and needs to help users in vertical industries to get connected. 5G LAN not only has the advantages of the original cellular network LAN resource sharing, fast network deployment, and security protection, but also adds new application functions such as Layer 2 communication, broadcast/multicast, etc., and improves the use of LAN in industrial Internet and intelligent building scenarios. lower permeability.

What is 5G LAN?

5G LAN technology is a new feature defined by the 3GPP standard in the R16 stage. It is based on the access capability of 5G wireless terminals and the private mobile LAN service provided by the 5G network. Provide flexible communication services such as terminal intercommunication or terminal isolation for terminals in the group. The LAN can support point-to-point and point-to-multipoint communication modes based on IP or Ethernet. To put it simply, it is to use 5G interconnection technology to "group" and "build groups" of terminals to form a LAN network.

Get through the integration of industrial IT and OT

Traditional industrial networks are based on wired transmission, and a large number of Layer 2 Ethernet protocols are used. In order to transform the industrial network into a wireless one and cut the braids of the industrial intranet, before the emergence of 5G LAN, people have tried to introduce AR routers to configure a virtual layer-2 network to achieve wireless access to 5G industrial terminals.

When the 5G LAN was born, it brought the most prominent and most important point. The network it established can complete the connection with the user's existing data network, so as to realize plug-and-play, mutual access, and save the intermediate network. By introducing an AR router to configure a virtual layer-2 network, the tedious link of 5G wireless access for industrial equipment is realized.

Because of this, the greatest value of 5G LAN lies in the transformation of the production environment of the park and the transformation of the grassroots network of production-oriented enterprises such as industrial manufacturing, ports and terminals, and energy mines.

Continuing to take industrial manufacturing as an example, 5G LAN has opened up the "two channels" of industrial IT and OT integration in one fell swoop. It does not need to add tunnel equipment such as AR routers, so that 5G can directly enter the factory intranet, and at the same time support user mobility, Subdivided subnets, and subnet-based management capabilities, realize minimalist network and flexible configuration, and form integration with industrial networks.

In addition, another important function of 5G LAN that is different from previous features is to support broadcast and multicast. This feature is also applicable to IP layer communication and Layer 2 communication. The traditional point-to-point communication method only supports unicast. For scenarios across UPFs, it depends on routing. For scenarios where a large number of UPFs need to communicate with each other, the topology will become more complicated. In addition, the policy management of business flows can only rely on UPF ACL to achieve.

It can be seen that the introduction of 5G LAN, especially the network's native support for Layer 2 communication, has promoted the integration of 5G wireless networks and industrial networks. In addition, 5G LAN technology has significant advantages in plug-and-play, cross-domain networking, and network determinism. Technical advantages have very broad development prospects in various fields such as campus networks, power grid differential protection, and industrial PLCs; especially for Internet of Things companies, the commercial explosion of 5G LAN is inevitable, and it has become a vertical industry to promote 5G innovation A new engine to apply, expand production efficiency, and accelerate digital transformation.

Promoting 5G innovative applications to speed up the new engine of digital transformation

At present, the commercialization process of 5G R16 continues to advance, and end users in the Internet of Things industry are making efforts to occupy a place in the 5G LAN commercial field. Earlier, some chip manufacturers joined hands with their ecological partners to realize the world's first business verification based on the 3GPP R16 protocol version, and launched a variety of 5G R16 module products, laying an important milestone for the commercialization of the 5G R16 standard.

As an expert in IoT technology and a pioneer in 5G AIoT technology, Four-Faith has always been one step ahead in the research of 5G industrial terminals. When the 3GPP R16 standard was oriented to the public, Four-Faith’s 5G industrial router series had already entered the 5G LAN testing and certification work. middle. At present, this series of Four-Faith terminal equipment has supported the key features of 3GPP R16, such as 5G LAN, 5G network multi-slicing, and high-precision timing, to meet 5G R16 application scenarios such as smart grid, smart manufacturing, smart building, smart logistics, and smart ports. demand, giving birth to a new digital ecology.
