The other method and one much preferred by the many business travellers is to access a WiFi signal via your own laptop or similar device. WiFi zones are also known as hotspots.
You will find these wherever you see this sign:
Internet access is provided by several ISP's and networks, namely T-Mobile, BT Openzone, Ipass, Boingo (require a program download in advance), The Cloud Networks (will get you on the Nintendo gaming network) and Surf and Sip. The area covered by these hotspots is pretty wide and takes in not just the terminals (arrivals and departures) but the airport piers and satellites too.
Making connection to the internet through a provider will require you to have a password and username. You can save time by setting this up before you travel by going to the appropriate suppliers website or at the time following the onscreen instructions that will appear once you click on a network signal to join it.
Dixons stores at the airport are also able to provide information and help with WiFi access.
Conveniently the airport terminals can also provide power for your laptop. To power up just look for the T-Mobile laptop stations or BT Openzone powered chairs.
