WLAN Technology Overview and Benefits
WLAN is Wireless Local Area Network, its full name is Virtual Local Area Network, which is a completely different LAN networking method from traditional LAN. In traditional LAN construction, all devices and users must be physically connected to the same network segment, which imposes requirements on the physical conditions of devices and users and restricts the development of modern networking technologies.
If the device and the user are geographically far apart and not in the same network segment, a wired LAN cannot be formed. However, WLAN technology can break through this limitation. Regardless of the physical location of the device and the user, a local area network can be built wirelessly through routers and network switches, and has all the functions of a traditional local area network.
Opportunities and challenges coexist in China’s mobile Internet industry. On the one hand, with the advent of digitalization of industrial information, technologies such as artificial intelligence, cloud computing, IoT, and 5G are scaled up, commercialized, stacked, integrated and innovated, which greatly promotes the transformation and upgrading of the entire Internet industry. On the other hand, although the basic software and basic network supporting facilities have become more and more perfect in recent years, there are still deficiencies in the entire industry ecological chain, and the public lacks sufficient understanding of network security. At present, in the era of Internet of Everything, relying on the rapid development of Internet of Things technology, more and more home appliances and equipment are connected to users through WLAN technology and Bluetooth, which replaces traditional network cable access and reduces wiring requirements. The multi-device access link of the smart home can be realized through mobile phones and routing and bridging devices.
The Future of WLAN Technology
The 5G bearer network is the basic network construction that provides network connections for the 5G wireless access network and the core network. The wireless local area network is an important part of the 5G network. Whether performing computationally-intensive tasks remotely, accessing large databases, or sharing experiences among users, networking and communication are essential. Under the background of the new era, science and technology are changing with each passing day, and the development of industrial-grade networks requires higher requirements for the network bearer system. In the 5G network architecture, the network is relatively dense. The characteristics of high frequency, low delay, and stability of the 5G wireless network have brought about earth-shaking changes in people’s life and work. For industrial park networks, 5G network technology is helping thousands of Digital transformation of all industries.
Combination of IoT and WLAN. Relying on the characteristics of wireless local area network, after entering the 21st century, with the development of smart terminals and smart homes, a dual-network fusion system of WLAN wireless network and Internet of Things is formed. In the Internet of Things, various sensors receive information from the physical world, use wireless networks to process and forward, and operate and control feedback on objects of concern. A TV is connected to the home network segment through WLAN technology, can receive processing instructions from the mobile phone, and realize many functions through remote operation. On the widely deployed WiFi products, the multi-port and short-distance access methods constitute the smart home system.
But at the same time, with the deep integration of the wired access network and wireless network of the 5G network, the wireless local area network is interfered by many factors, and network information security issues also frequently arise, and there are some security risks. The security of WLAN in 5G is a hot topic of people’s livelihood. As the first country in the world to realize 5G construction, China has made great contributions to key breakthroughs in 5G technology. The output of basic equipment such as 5G optical modules continues to grow rapidly, building a It has established a complete ecological chain of 5G Internet of Everything, and set a leading example for the global exploration of 5G security issues and 5G commercialization.
