Many businesses use wireless networks either alongside traditional wired networks or as an alternative to them. Wireless technology is convenient and built in to a growing number of devices including laptops, smart phones and tablet computers.
Implemented correctly, a wireless network can bring significant benefits to your company.
Wireless networks do the same thing as any other computer network: they link together computers and other devices so you can share files, access the internet and use centralised applications. While traditional networks use physical cables to link computers together, wireless networks use radio waves.
The technology used in a wireless connection is usually referred to as ‘Wi-Fi’ or simply ‘wireless’. It’s similar to the signals used in cordless phones and allows for the transfer of data between wireless devices without any cables.

There are a number of benefits to setting up a wireless network in your business:
However, although wireless networks are easy to set up, they have a few drawbacks which mean they’re most often used alongside a wired network:
Wireless networks are particularly useful in situations where running cables would be difficult, or where you want extra flexibility – perhaps to offer a network connection to visitors or in your meeting rooms.
You need two essential pieces of wireless equipment to set up a wireless network:
An increasing range of devices now come with wireless capabilities as standard. Every laptop made in the last couple of years will have wireless networking built in.
You can add wireless capabilities to desktop computers by purchasing an adaptor for £20 or so.
There are several different speeds of wireless network, each with a different, hard-to-remember name (802.11g and 802.11n are the most common). You don’t need to worry about this too much, as devices which run at different speeds should work together. Just opt for the fastest you can afford – at present, that’s 802.11n.
If your business already has a wired network, you can usually plug your wireless access point straight into it. Position the access point so the signal covers the areas you want it to.
Once it’s set up, take some key security precautions. Enable encryption so it’s harder for people to intercept information being sent across your network. Also consider hiding the network so it doesn’t show up when people scan for wireless networks.
Many wireless access points will offer a step-by-step guide to help you get set up. However, it’s worth contacting your IT supplier for assistance with more complicated set ups – particularly those involving several access points or large premises.
