Wireless Network experts talk about preparations for deploying wireless networks for Enterprises

With the popularization of Wireless terminals, more and more devices need to use wireless networks. For enterprises, deploying wireless networks is imminent. Now wireless Internet access has become a popular trend. for small and medium-sized enterprises, due to its ease of use and low investment, wireless networks have gradually become a new trend in the Internet Office era. If you deploy your company's wireless network without preparing for the wireless network, you may encounter network problems such as bandwidth insufficiency, network disconnection, and unstable card network.

Therefore, it seems that preparation for enterprise wireless network deployment is very important. What aspects should we prepare? We found several wireless network experts to discuss the results.

Device Vendor Selection

After consensus, we believe that the device vendor's choice has ranked first, you must select a company with a certain number of products in the wireless network, provide excellent services, and have a good team with good technology to avoid unnecessary troubles.

Integration with existing networks

A virtual LAN can be implemented in many ways, such as IP addresses, ports, and protocols. If it is based on port: It should be noted that it may cause unnecessary trouble

You can set the port-based implementation method to the IP address or MAC address-based implementation method.

What kind of wireless transmission standard protocol device is selected

For example, if you have selected a device that supports the 802.11g protocol, you have to change the device when you find that the device cannot be used. Or, you can check which protocol is supported by the existing device, then select the type.

Wireless Networks cannot completely replace wired networks.

This is a concept, and we hope that as managers can agree that although wireless networks have many advantages, wireless networks still cannot completely replace wired networks. Some time ago, a network administrator felt that the wireless network signal was quite good and stable. He installed the wireless network card on the company's WEB service and removed the wired network, later, due to a Wireless AP failure, the company's website could not be accessed, which would cause serious losses.

In some cases, application interfaces on various hosts and servers can cause major problems when using wireless networks. For example, a user may be using an inventory management application that scans an item and uses the keyboard on the scanner to enter the total number. If the connection is interrupted after the barcode is scanned and before the total number of inputs, the host-based application may be used up if the inventory processing is not completed. Therefore, this application may record incorrect or invalid inventory items on the host. To avoid such risks, it is best to use a wired network to ensure data correctness.

Department Arrangement

We recommend that you separate the SSID when deploying wireless networks in the guest area, conference room, and office to avoid network insecurity. For a company, wireless networks are not used everywhere. For departments with high security requirements, it is best not to deploy wireless routers. For example, the R & D department may be the key protection department of the enterprise. Do not deploy a wireless router to ensure the security of their department information. For convenience and security, we often choose security. After all, if such information is leaked, it may cause a fatal blow to the Enterprise.

Installation Location Selection

1. radio frequency interference. Equipment such as 2.4 GHz and 5 GHz cordless phones, microwave ovens, and nearby networks can cause destructive radio frequency interference, affecting the performance of a wireless network. To minimize the risk of radio frequency interference, perform a wireless site survey before installing the access point to detect interference and anti-interference measures.

2. Try to deploy the wireless network in the center of the office area. 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.

3. 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.

4. Do not hide the AP for the sake of appearance. This is of course due to signal strength.

5. Whether devices can achieve Seamless Roaming after installation

Manageability of network devices

Product management must be human-oriented. It can take many factors into account for management personnel. It is easy to use and easy to debug.

Security of Wireless Networks

Network security is mainly manifested in encryption and authentication. Through wireless controllers, multiple encryption and authentication methods can be implemented to completely eliminate the risk of internal network access by illegal terminals. To minimize the coverage of wireless access points, enterprises with higher requirements should use firewalls to separate one or more wireless networks, or you may want to deploy a Wireless Access Network in DMZ or the surrounding network,

You can also use IDS or response sensors to monitor all connections on the wireless network. Use network access protection to manage wireless clients so that they can be correctly set before the computer uses the network.

When deploying an enterprise's wireless network, you must make a feasible solution based on the actual situation. Of course, some enterprise's network management personnel may not be able to fully consider the capabilities, we recommend that you find some device manufacturers to provide solutions for you, and then you choose the best option. Wireless Internet access is just a connection technology, and it cannot change the purpose and feeling of Internet access, enterprise Users are even more so. Simplicity, directness, efficiency, security, and convenience are the real purposes of our wireless application.
