If you have trouble receiving calls at home or in the office, there is now technology that gives you a mobile signal in places without one.Femtocells are mini phone masts which can piggy back on your broadband connection to send the call to a mobile operator.
Steve Lightley from NEC Europe reckons they are coming to your home soon.
"They've been deployed in Japan and trials are ongoing in UK and Europe," he said.
To use them a mobile does not need to have wi-fi and it is expected that some home routers will have the technology built in later this year.
