Wireless Network Anti-interference switch controls AP

In many cases, wireless technology is not a single use. The combination of wireless technology and other network devices is the current trend. How can we control interference with signals on networks?

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 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 interference prevention-bottlenecks in Wireless Network Access

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, users will often see a prompt window that automatically searches for and reconnects to the wireless network, this greatly damages the continuity of network connections. In particular, compared with wired networks, it requires real-time smooth connections for some key business applications of enterprises, such as VoWLAN (voice applications based on wireless LAN, it is even more unacceptable to achieve switching through network pauses.

Obviously, for security, there are some established standards in wireless network security technology, and there are many standards-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.

Anti-interference in wireless networks: Traditional AP independent

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.

Generally, the number of APS in an enterprise network is deployed based on the signal coverage and physical space matching. Obviously, if it is only an AP, there will be no signal interference, but the stability of wireless access will become a problem when the number of access requests increases. However, there are more AP scenarios. In this case, 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.

Wireless Network Anti-interference, ask the switch to divert the AP

At first, many users valued the coverage of Wireless AP signals, so that the manufacturer would regard this as a very proud parameter when promoting the product. However, we know that, unless we build a wireless network at home, as long as it is an enterprise network, users are almost reluctant to connect to all wireless terminals with 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.

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, extricom sets each frequency band as a relatively independent network, thus forming four wireless networks, each network can be controlled by a WLAN switch for different businesses or departments of the enterprise. In each network, the AP can be controlled by a WLAN switch to provide a non-interference connection to the terminal; in addition, Extricom fine-tuned the AP in each AP so that it only has the radio function, no configuration, no IP address, and no need to process data, in this way, the antenna group can be added to achieve small capacity redundancy on the channel.

It is also reported that even if multiple terminals are connected to multiple APs at the same frequency, the WLAN switch can achieve zero interference through time-sharing.

Summary of wireless network anti-interference

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, the intervention of WLAN switches has played a surprising role in the wireless LAN connection by traditional IT technologies.
