Will wireless replace the Integrated Wiring of enterprise networks?

Enterprise Network Integrated Wiring is still quite common, but with the continuous development of information technology, wireless networks have become deeply rooted in the hearts of the people, and its own advantages are unmatched by WIRED wiring, here, I will analyze the differences between wired and wireless networks and give them a comprehensive comparison.

Wireless: Real and necessary

Editor's note: In the past, we used Wireless Office as a fashion, such as chatting online in the coffee shop and posing in the airport lobby with a wireless laptop. Now, wireless applications have begun to penetrate into a variety of enterprise applications. In some enterprise integrated network cabling applications, wireless applications have even become a tool to replace wired networks.

Some enterprises, especially large sales enterprises, do not have fixed office positions, for example, a sales project manager may have 80% of the time to hold meetings in different locations (internal meetings, meeting with customers, and communicating with colleagues separately) in a day ), wireless access has become a necessary means of work. For another example, how can we achieve network coverage without changing the building and wiring of old-fashioned hotels? Wireless networks are a good solution. In a large field, how can we build a network monitoring and management system at a low cost and efficiently? Wireless Networks are much better than wired networks .....

Without a doubt, wireless applications have penetrated into the Integrated cabling of enterprise networks, which will not replace wired networks, but has become an important role. However, we still have many questions: What wireless access methods do different enterprises need? What is the security problem of wireless networks? What are the advantages of wireless networks over wired networks?

Wireless: Real and necessary

For Wireless Office, some people still have the issue of distrust. They think that it is not professional and safe. In enterprise applications, it often does not involve key business of the enterprise and does not affect the business efficiency of the enterprise. In fact, for most enterprises, as mentioned above, wireless access does not involve key businesses of enterprises, and does not affect the operational efficiency of enterprises.

However, for some enterprises, such as large sales enterprises, hotels, university campuses, restaurants, etc., wireless applications play a key role to a considerable extent, such as the wireless ordering system, it even determines the operating efficiency of the restaurant. Now, let's analyze the enterprise needs of wireless applications in depth:

For some enterprises, especially the sales and office departments, there are several important wireless application requirements:

1. company meetings/training/Lectures
Various meetings of the company may be internal regular meetings, negotiations with customers, etc. The laptops in the conference room can be wirelessly logged on to the company's website or cited on the Internet, or share files between employees. It can be easily implemented in wireless mode.

2. Temporary team
The company sets up a temporary team for a project. The team members may work together until the project ends, maybe several months. Group members can directly connect networks without base stations.

3. Entry of external staff
The staff of the Branch Office should report to the headquarters, receive training, or audit the company to audit the company, which must be connected to the company's network to facilitate work. With wireless networks, our staff can quickly access the Internet without interrupting their normal work.

As shown in the preceding figure, relatively large enterprises have higher wireless requirements and smaller wireless requirements for small enterprises. In this regard, Pan Heng, wireless product manager of D-link, analyzed: "small enterprises have a relatively small number of employees and their offices are relatively stable. Therefore, mobile Internet access is less demanding. From the sales figures of D-link, the wireless sales of medium and large enterprises are much larger than last year, while that of small enterprises is less ."

The hotel is actually a good breakthrough in the wireless market. For example, Netgare said: "banquet and room requirements for some five-star hotels are international, and there are also network requirements in meetings. wireless coverage is imperative ."

In a renovated Hotel, when it needs to deploy a network system, rewiring the enterprise network will affect the entire environment, and the cost of integrated network cabling is relatively high. The use of wireless networks can minimize the impact of decoration and save costs, making installation and use very convenient. You only need to deploy a wired and wireless AP to achieve full-range Internet access.

In fact, there is still a good way for wireless hotels to use a coaxial cable wireless signal splitter so that wireless signals can be transmitted through the hotel's cable TV network, share wireless network signals with cable TV signals. In this way, every room in the hotel can enjoy the convenience of wireless network.

In addition, the wireless solution is undoubtedly a good solution for large areas, such as large-scale field fields, parks, university campuses (playgrounds), residential areas, and airports. Wireless Networks are superior to wired networks in terms of integrated cabling costs and maintenance management. At this point, we may need to introduce wireless switches, multiple AP bridging functions, and wireless MESH technology ......
