There were many wi-fi signals as I walked through the airport. The main official ones seems to be all pay ones so I kept looking. I found a fast and free one by sitting outside a business lounge and was able to check e-mails and make a web-call home. There weren't a lot of power points that I could see, at least not close to anywhere to sit. The airport has lots of shops and fairly long walks between gates so I got to see a fair bit while waiting between flights. Didn't try cell or look for any fixed lines.
