Wireless networking: The pros and cons


Wireless networks, or WiFi as they are more commonly called, offer many key advantages over wired networks.

Wireless networking has many advantages

Efficiency increases

Data communications are faster and more efficient, which allows for quicker information transfer within companies as well as between customers and partners. Salespeople can, for example, remotely monitor stock levels and prices during sales calls.

Accessibility and availability

Wireless technology allows users to communicate on the go, so you’re never far from your computer. You don’t even need additional cables or adaptors for office networks.


Wireless workers who work from home can connect to the internet without having to use dedicated computers. They can also continue their productive work even if they are not in the office. This could lead to new ways of working such as working remotely or having direct access to company data from customer sites. Learn more about employees who work remotely.

Cost savings

Wireless networks are easier and more affordable to install than traditional cables, particularly in older buildings that have been listed or where permission is not granted by the landlord.

There are new opportunities

You could offer new products and services through wireless networking. Many airport departure lounges, train stations and hotels have installed WiFi hot spots to enable mobile users to connect to their home offices from their mobile devices while they travel.

Wireless networking has its disadvantages

Wireless networks offer many advantages over wired networks. However, there are potential WiFi drawbacks.


Wireless transmissions are more vulnerable to unauthorised users. Therefore, you need to pay attention to security. Security of your wireless networks

Installation problems

Interference can occur if other people in the same building use wireless technology or are exposed to electromagnetic (radio-) interference. This can cause poor communication, or even complete loss of wireless communications in extreme cases.


Some buildings may not have consistent coverage, which can lead to “black spots” where there is no signal. You might have difficulty picking up radio frequencies in buildings made with steel reinforcement materials.

Transmission speeds

Wireless transmission is slower and less efficient that ‘wired networks. Larger wireless networks have a ‘backbone’ network that is wired or fiber rather than wireless.
