Advantages and disadvantages of network data cabling

As more and more devices and electronics are designed to make use of wireless networks for network connectivity, it is necessary to evaluate network data cabling before creating a new device or system in your home or office. In many cases, a network that uses physical cabling is more robust and secure than a wireless technology network. Read on for a few of the benefits of network data cabling as well as some of the drawbacks of wireless networks.


One of the primary benefits of network data cabling is that they provide a higher level of security than wireless networks. Although security measures, including passwords and protected Wi-Fi networks, help improve the security of wireless networks, they are never as secure as network cable systems.

Reduced interference

Proper installation of network data cabling helps dramatically reduce the interference caused by electrical and radio frequency, known as electromechanical and radio frequency interference, respectively. Wireless networks are extremely susceptible to radio frequency interference problems. This is not the case with shielded network data cabling and fiber optic cable.

Consistent connection

One of the major concerns that many wireless network users have is the inconsistency of the connection. When data transfer is performed, a loss of network connection caused by an instantaneous loss of wireless signal or electrical interference can effectively ignore a great deal of work, slow down the transfer rate significantly or introduce unacceptable levels of data corruption. Fortunately, network cabling provides a constant connection that does not suffer from these immediate lapses.


While not all network cabling will provide a fast connection, the newer types of wired data cabling can work at data rates up to 10 gigabytes. Fiber optic cabling transmits light rather than standard data, making it optimal for high-speed use and extended ranges.


A major disadvantage of setting up network data cabling is mobility while connected to the network. Wireless networks provide excellent mobility for electronic devices because there are no wires that prevent movement within the range of the transceiver. Unfortunately, users must be directly connected to a network cabling system to take advantage of the data transfer capabilities.

If more than one physical computer connection is required when using physical network data cabling, it is usually a simple matter to connect a router or hub to the already installed network connection and connect network devices to the hub or router. Each hub or router can support up to 255 devices.


While wireless networks are relatively easy to set up, a physical network data cable system must be installed before use. This means that the cable must be routed and terminated correctly at both ends. This usually means accessing the crawl space and the interior of walls as well as cutting holes in walls.
