A lack of planning can mean that the network no longer optimally meets the requirements demanded by IT. For example, problems can arise with the provision of capacity reserves or high costs for expansions. The available bandwidth and flexibility of use are also crucially dependent on the network structure

 

What role does cabling play in this context?
The advantages of LAN and WiFi are quite different. Despite the high ease of use of wireless networks, most companies cannot do without the use of network cables. A major advantage of LAN is the high bandwidth of physical cables.

Another problem with WiFi is that companies often have many clients working in a confined space, which quickly affects the bandwidth and reliability of data exchange. With wired networks, this "shared medium" problem can be eliminated by using switches. In addition, cables are also preferable to wireless connections for security reasons.

The central objective of structured network cabling is not only to provide capacity reserves, but also to support modern communication technologies. However, the simple installation and connection of network components are also essential factors in network planning.

​

In principle, structured cabling can be divided into three levels. These levels consist of premises, building and floor cabling. Whereas the ground cabling connects individual buildings with each other, individual floors are networked in the building cabling. Due to the small number of stations, mainly fiber optic cables are used in the area cabling. In building cabling, copper cables are also used. It is important that a length of ninety meters is not exceeded when using twisted pair cables (CAT5 / CAT5e / CAT6 / CAT6).
