According to in- formation from the company, by using a transparent antenna, an ordinary win- dow could easily become part of the mo- bile broadband network, boosting indoor coverage for an improved mobile experi- ence inside buildings. Jan Hederen, strategy manager of De- velopment Unit Radio for Ericsson, says that using the window to boost signals may be a first step toward a new way of thinking about communication. “Com- munication is everywhere and plays out as the bridge between different services such as energy, security, media display, interac- tion and communication with the network in itself (as a gateway to the Internet).” What about communicating mes- sages to external viewers?
