Network basics: Wi-Fi wireless network deployment

Wireless Network is the basis of network technology, but WI-FI technology is the basis of wireless network technology, so we need to understand the WI-FI technology from what angle? The following is a detailed introduction.

Wi-Fi wireless network deployment basics, now every household has their own computer, learn about Wi-Fi wireless network deployment, ADSL settings, wireless Security Settings make it easier for you to understand the wonderful world of the Internet.

It may be because Wi-Fi wireless network deployment is growing too fast. It seems that wireless has become the main consumer for both home users and individual users, this is clearly not the true purpose of Wi-Fi wireless network deployment technology developers. As a local network that uses wireless signals as the transmission medium, the characteristics of wireless networks will be given full play in the office environment.

First, the biggest feature of Wi-Fi wireless network deployment is that it eliminates complex cabling in traditional wired networks and does not require strict environment arrangement. Secondly, the flexible mobility of wireless networks is also limited by signal transmission distance and power supply. In many scenarios designed for advertisements, power supply problems cannot be solved in coffee houses or other places, in the office environment, you don't have to worry about this. Third, the LAN features of Wi-Fi support more computer interconnection, and home users cannot make full use of this feature.

Of course, we cannot blame the vendor for its publicity. Wireless Networks tend to be in the personal market. The current situation is also the result that business users have too high requirements on the network, and security issues have been unavoidable. While constantly improving products, major network manufacturers have to "start" their personal users with low requirements. Intel has made an indelible contribution.

Now, with the help of new technologies, many companies have successfully deployed wireless LAN. From then on, we can no longer see the network cables flying all over the sky, and the conference room is also quite neat. Especially in the Process of meetings, attendees can view the required information at any time without worrying about finding a network cable.

Of course, Wi-Fi wireless network deployment will bring many unexpected benefits. For example, the network management system does not have to worry about the failure of one or more switches. The administrative department can also design a more imaginative office compartment for the company. In addition, we may use the existing wireless network, understand the convenience and speed brought by Wi-Fi cameras, Wi-Fi Mobile Phones, Wi-Fi projectors, and other devices.

All these applications are obviously more attractive than the wireless products in the original advertisements. But how can we deploy a set of reliable, secure, and stable wireless networks in the office? Is it the same as the home wireless network? let's solve this problem today.

Wi-Fi wireless network deployment:

The deployment of traditional wired LAN is often used as an important project. No matter the station design or the number of internal nodes, there will be strict arrangements, while the wireless network is relatively too simple. First, we also need to estimate the number of nodes, because it will not be related to the number of switch ports, so this is no longer as strict as the wired network, as long as it can be roughly estimated.

Then, we calculate the total number of APS we need based on the number of nodes supported by the AP (Wireless Access Node. Generally, it is appropriate to use an AP to support 30 to 50 terminals (about 100 terminals are supported theoretically ). You can use either of the following two methods to connect an AP. One is a wired connection, which is the same as that of a traditional wired network connection terminal.

The other method is to use the automatic bridging method on the AP for connection, but this method will put forward higher requirements on the AP performance. You must select a product that supports bridging when purchasing the SDK. After all the APS are connected, the wireless network can be connected by setting the corresponding IP address and the name of each AP. Devices in a wireless network are basically no different from those in a traditional wired network.

Wi-Fi wireless network deployment of wireless signal coverage

Wireless networks use wireless signals as data transmission media. Therefore, how to ensure signal coverage is the key to deploying wireless networks.

◆ Wi-Fi wireless networks should be deployed in the center of the office area whenever possible. Because the coverage of wireless signals is a circular coverage based on the emission point and the closer the signal is, the deployment plays an important role in future applications.

◆ Wireless AP should avoid electronic devices that are close to microwave oven, radio, and other devices that may cause signal interference.

◆ Do not care too much about the cost. Try to find more than two "hotspots" (signal sources) at each station. Of course, the signal strength may vary depending on the distance, however, if an AP is used to support applications, the application in the entire region will be affected if the AP fails.

◆ Do not hide the AP for the sake of appearance, which is of course due to signal strength.

If you can pay attention to the above aspects, the Wi-Fi wireless network deployment in the office area will inevitably give users a relaxed feeling of use, and will make the scenario at the beginning of this article easy to become a reality. Last but not least: Wireless is not a show. Although this article is about commercial wireless networks, I still want to make some small comments on the current situation of wireless networks.

Wireless Internet access is only a connection technology and cannot change the purpose and feeling of Internet access. Fashion is also used to "show" things, and surfing the Internet in coffee shops and other places does not have the excitement in the internet cafe or the comfort of the home. For this fashion, it is really tiring to deliberately suffer from crimes outside. SO, wireless is not fashionable.
