coondoggie writes "The crew of the classic science-fiction show's Starship Enterprise wore small devices on their chests that they could tap to communicate instantly with their colleagues. Such communications technology is now closer to reality thanks to a Finnish company which this week demonstrated high-tech clothing that can send and receive messages via satellite. The demonstrator antenna, built by the Patria Aviation Oy company, looks like a simple patch of cloth but is capable of operating in the Iridium and GPS frequency band as part of clothing. The Iridium satellites allow two-way voice and data communication, while GPS provides positional data to the user. Iridium could also relay the position of the user."
