"Network traffic police"-a wireless LAN switch

Wireless LAN is a commonly used network in enterprises. Therefore, for an enterprise's network configuration, how to use wireless LAN switches, wireless routes, and Wireless AP devices is an ideal and reasonable solution, facilitating network management is a question worth thinking about. Here we will mainly introduce the wireless LAN switch, which serves as a "traffic police" in our daily life, so that our network can be kept smooth and our network can be properly guided.

Wireless LAN switches are worth learning. Here we mainly introduce how Wireless LAN switches control wireless network access points. There is no interference in the signal and seamless network switching, so there is a wireless network connection method that can achieve this effect. It is also a pure wireless connection solution. The difference is that it slightly controls the traditional Wireless AP (Access Point)-deploy a wireless LAN switch on the upper layer, configure the channel and monitor and deploy multiple aps in the lower layer, enables non-interference and continuous wireless network connections.

Wireless Network Access bottlenecks

We all know that the emergence of wireless networks is to achieve network access through a certain range of signal coverage without the limitations of Network cables, but in practical applications, in addition to the test of information security, the application environment full of radio signals faces the trouble of generating signal interference. In addition, when a mobile terminal, such as a notebook, moves in a network environment with multiple wireless APs, the copyright of the project network is controlled. Users often see the prompt window for Automatically Searching and reconnecting wireless networks, this greatly damages the continuity of network connections.

In particular, compared with wired networks, the project network is copyrighted. For some key business applications of enterprises, such as VoWLAN (voice applications based on wireless LAN), real-time smooth connections are required, it is even more unacceptable to achieve switching through network pauses. For security, there are some established standards in wireless network security technology. Correspondingly, there are many standard-compliant information encoding technologies that can implement information encryption. However, there have been few breakthroughs in signal interference and seamless switching. In the face of the rich network applications of enterprises today, in addition to data, real-time communications such as voice and video are increasingly required, and the convenience of network access is also more urgent, signal interference and network switching are becoming the bottleneck for wireless network access.

Traditional AP

In fact, the wireless access process associated with the wireless network is the wireless communication at or below the network layer, that is, the process of sending and receiving wireless signals. In this process, the PC or other portable devices as the terminal search for available APS by sending radio signals, when it finds a relatively strong wireless signal, it establishes a wireless connection with the corresponding AP to achieve network access through the AP, if it is only an AP, there will be no signal interference, but when the number of access requests increases, the stability of wireless access will become a problem. However, there are more AP scenarios, at this time, the signal interference caused by multiple APS is difficult to control. Once the terminal moves from one location to another, switching between networks under the jurisdiction of each AP requires disconnecting, re-selecting, and connecting steps, which naturally interrupts the network applications at that time. Of course, it may be just a few dozen seconds, but for some instant messaging, this is also a very important link.

Enable the AP through a wireless LAN switch

At first, many users paid great attention to the signal of the Wireless AP. The Wireless LAN switch covers all rights reserved by control engineering China, so that the manufacturer will regard this as a very proud parameter when promoting the product. However, we know that, unless a wireless network is built at home, as long as the network of an enterprise is controlled by ENGINEERING China, almost all users are reluctant to connect to all wireless terminals by using only one AP. The reason is very simple. Even if the range is available, multiple APs are needed to distribute connections in case of a large number of connections.

The idea is ideal and understandable. But I don't know. If the AP is put there, the enterprise's wireless network is equivalent to an electromagnetic network composed of dense radio signals, which is unhealthy and environmentally friendly.

If we pay a little attention to it, enterprise users have long been in demand for wireless networks or Wireless AP management, but many users only need to control the login password, the actual signal connection is not managed or controlled. However, if we try to add it technology to the AP connection field, we may think more about the product called the wireless LAN switch and its functions.

Yes. Use a switch to control and switch the AP. In addition, due to the wireless LAN protocol, that is, 802.11, there are four protocol frequencies a/B/g/n, and each of the six adjacent channels in each band has interference, by setting each frequency band as a relatively independent network, four wireless networks can be formed, each network can be controlled by a wireless LAN switch for different businesses or departments of the enterprise. In each network, the AP can also be controlled through a wireless LAN switch to provide a non-interference connection to the terminal. In addition, the AP can be fine-tuned in every AP so that it only has the radio function, no configuration, and no IP address, you do not need to process data. In this way, you can add antenna groups to achieve small-capacity redundancy on the channel. It is also reported that even if multiple terminals and multiple APs are connected at the same frequency at the same time, control engineering China is copyrighted, the wireless LAN switch can achieve zero interference through time-sharing.

Summary

The AP is still those APs, But if more channels are needed, the AP can be disassembled slightly, that is, adding a few more antennas. However, control engineering China is All Rights Reserved. The involvement of Wireless LAN switches has played a surprising role in the use of traditional IT technologies in Wireless LAN connections, the implementation of non-interference Wireless LAN will open a new page.
