Wired networks are like the transport trucks of the digital age; they're nothing flashy, but they get the job done reliably and efficiently. There are several advantages to setting up a wired computer network, and several cases where they are more effective than their wireless counterparts.
The cost to set up a wired computer network in today's marketplace is generally quite low. The hardware involved is minimal — you can pick up wired network adapters for next to nothing — as well as the labour to set up and maintain the network.
Most networking issues are a result of wireless networks, and all the security concerns related to them. With a wired network, you operate in a closed loop system lowering the need for security measures. Less security systems to set up means that your network is plug-in and go.
Wireless technology is improving, but there still really is no comparison to which is faster. Cost effective wired technology can operate at 1Gb/s (1000Mb/s), whereas most wireless networks operate at 54-108 Mb/s — and that's a best case scenario. That means that a wired computer network is still 10 times faster than the best wireless technology. If you are a company that regularly transfers large files, then a wired network could save you time and money.
ReliabilityAlong with wired networks comes the peace of mind in knowing that your connection will remain uninterrupted during the transfer of important files.
Wireless networks are dependent on the strength of the wireless signal. Depending on where you are located, anything from walls to your own body can reduce the strength of the signal available. This directly affects your network performance, and can potentially interrupt it.
Often companies will adopt a hybrid approach to networking, utilizing a wired computer network for key workstations and the remainder functioning on the wireless system. This allows you to benefit from the best of both worlds; you get the speed and reliability of a wired network at your key stations and as an emergency backup, but you also benefit from the portability and ease of access of wireless.
