Brief Introduction to several alternative uses of Wireless LAN (1)

Although there are still some difficulties in deploying wireless LAN in enterprises, the value of it cannot be negated. Wireless LAN is still of great application value in enterprises. I will not talk about the conventional use of wireless LAN. Next I will talk about some of the alternative uses of Wireless LAN that have made me feel deeply.

I. using wireless networks to form a micro-cellular system

If you are on a business trip one day. Before boarding the plane, I had just finished calling in Beijing. After the plane leaves, he calls Guangzhou. At this time, although the phone is called in the same way, the signal receiving point of the mobile phone has changed. The micro-cell system allows a user to roam freely in different access point coverage areas. As the geographical location changes, the signal is automatically switched from one access point to another. The most important thing is that this entire process is transparent to users. Although the server that provides signals has changed, user services and communications will not be interrupted, you do not need to make any adjustments.

In fact, the use of wireless LAN Solutions can also achieve similar needs.

For example, sometimes we may be using instant messaging tools for online conversations with customers, but the manager calls them to the office for a meeting. If there is no wireless LAN, we have to stop the conversation temporarily. Now, if you deploy a wireless LAN in the conference room, the problem will not be solved. We only need to take the notebook to the Office, and our notebook will automatically find the wireless network signal in the location. After finding it, it will automatically connect to the Internet. In this case, the user can talk to the customer while holding a meeting to listen to the leaders' instructions. In this case, the customer will not be disgusted and let the customer wait.

Therefore, we can deploy several wireless signal transmitters in some important locations of the company, such as the reception room and conference room. In this case, if we move from one location to another, you don't have to be constrained by network cables. You can access the Internet Anywhere. It is convenient to present the company's products to the customer and allow the customer's own computers to access the Internet.

Ii. Network redundancy using wireless LAN

If an enterprise has some information management applications, sometimes network interruption is very hard for them. For example, if an enterprise uses an Enterprise Resource Planning Management System, the network cannot be interrupted for users in a single day. A single disconnection means that many of their businesses cannot be carried out, including opening orders and shipping arrangements. In fact, not only this system, but also information applications such as file servers, email systems, and OA systems. When the network is interrupted, these systems will not be available, it will directly affect users' work.

In this regard, I also have deep feelings. I remember once, the company deployed a file server, and all the files related to the company were stored on the company's file server. The read and write operations on employee files are directly performed on the file server. For file security, there is no backup on the local machine. However, one day, I did not know why (and later I found it was a rat, and the network cable was broken to the mouse), and the network in an office was suddenly interrupted. Computers in this office can access each other. However, files servers cannot access computers outside the office.

In this case, the staff in this office are called the sky. In a short period of time, it is impossible to get disconnected again. What should we do? Fortunately, the company has several wireless routers. I picked up a wireless router in the office next to it, and then picked up a wireless router in another office to get signals from the wireless router in another office. In this case, the network communication problem is temporarily solved. This has earned time to solve network problems. The author has enough time to find out the cause of the problem on the office network and rectify the problem. You know, at that time, the company did not have a good network detection tool and did not know what went wrong with the concealed engineering of the network cable. Therefore, it is necessary to use wireless networks for redundancy. With this wireless LAN redundancy solution, we can also use it to ensure the effectiveness of network communication in an emergency.

Therefore, the wireless LAN redundancy solution is one of the magic weapons for our network administrators.
