Twenty minutes later and you have only seen five minutes of the film. The people talking on their phones have been forced to call back a dozen times, so they finally give up and send a text message. Recognise the scenario? Irritating isn't it?

However, most of today’s wireless networks still remain wired. This is partly because, over the last 40 years, researchers have not been able to determine network capacity. Nicolas Schrammar and Mikael Skoglund have been given an award for shedding light on this problem using an approximation model.
