Mobile communication speed record: One gigabit per second over the air

A world record was set at the research laboratories of the Siemens Communications Group. For the first time, data were transferred in real time via mobile communication at a speed of one gigabit per second (Gbit/s). By comparison: WLAN networks presently offer the fastest wireless links to mobile devices at speeds of around 50 MBit/s . In order to achieve its record-setting high speed, Siemens combined an "intelligent antenna system" consisting of three transmitting and four receiving antennas with Orthogonal Frequency Division Multiplexing (OFDM) . Researchers consider these technologies, which are especially efficient at using the frequently band, to be highly promising modules for the mobile communication generation beyond W-CDMA.
