NTT DoCoMo Achieves 1Gbps Packet Transmission in 4G

December 17, 2004

According to JCN Network, NTT DoCoMo announced December 17 that it succeeded in achieving 1Gbps in downlink packet data transmission in a laboratory experiment using forth-generation (4G) mobile communication radio access equipment on August 20, 2004.

The company employed two wireless access techniques, variable-spreading-factor spread orthogonal frequency division multiplexing (VSF-Spread OFDM) and multple-input-multple-output (MIMO) multiplexing, in the latest test.

The company also used its proprietary signal separation technique to enable data transmission at 1Gbps in realtime using a bandwidth of 100MHz in a area with low radio signal receptivity.

NTT DoCoMo aims to develop a 4G global standard in coordination with the International Telecommunication Union Radiocommunication Sector.
