  • DoCoMo Tests 4G Speed

    DoCoMo said today that this past summer they successfully achieved a 1-Gbps high-speed packet transmission (downlink) in a laboratory experiment using fourth-generation (4G) mobile communication radio access equipment, and are considering field experiments early in 2005. DoCoMo achieved 100- and 20-Mbps data rates in the downlink and uplink, respectively, in outdoor environments at a moving speed of about 30 km/h in July 2003.

    The implemented 4G radio access equipments employ variable-spreading-factor spread orthogonal frequency division multiplexing (VSF-Spread OFDM) radio access method and multiple-input-multiple-output (MIMO) multiplexing technique using new signal detection algorithm in order to achieve 1Gbps data transmission with 100MHz bandwidth in the downlink.

    NTT DoCoMo is currently conducting indoor tests with various radio conditions as preparation for future field tests to develop a 4G global standard in coordination with the International Telecommunication Union Radiocommunication Sector. In Japan, the telecommunications council of the Ministry of Internal Affairs and Communications is overseeing efforts to develop technologies for 4G commercial services by 2010.
