http://www.mobiletracker.net/archives/2004/12/07/siemens_has_1_g.php Siemens today announced that researchers at the Siemens Communications Group department have developed wireless technology capabale of speeds up to 1 Gbit/sec (1000 megabits per second). WiFi currently tops out at around 50 megabits per second, which is still quite faster than technologies in the US like EV-DO that top out at a little over 2 megabits second. Howver, don’t hold out for the new tech anytime soon: By the time the next generation of mobile communication debuts, which is expected to occur beginning in the year 2015, the need for transmission capacities for voice, data, image and multimedia is conservatively anticipated to rise by a factor of 10. Siemens combined an “intelligent antenna system” consisting of three transmitting and four receiving antennas with Orthogonal Frequency Division Multiplexing (OFDM). The research looks promising for “4G” or technology after W-CDMA (3G). This technology will be shown off at the 3GSM World Congress in February 2005. MobileTracker will provide complete coverage of the event. The experimental system operates in the 5-GHz band and has a bandwidth of 100 MHz. The Orthogonal Frequency Division Multiplexing (OFDM) transmission method that it employs protects the signals against most types of interference, such as the echoes that are produced when the signals reflect off buildings |
