In related news, Motorola has won a contract with TeliaSonera in Denmark to deploy its UMA solution (Unlicensed Mobile Access), for the operator's planned UMA service launch in the second half of 2006. UMA provides cellular mobility as well as better, cheaper coverage inside the home using a Wi-Fi connection. In addition, users will have a seamless mobility using a single device, a single number, contacts book, voicemail and billing."
