4G test breaks 1Gbps transmission barrier

20 Dec 2004

NTT DoCoMo says a test of 4G mobile communications equipment achieved a 1Gbps packet transmission back in August using variable spreading-factor spread orthogonal frequency division multiplexing (VSF-Spread OFDM) and multiple input, multiple output (MIMO) technology. The company has been conducting 4G tests since 1998 and hopes to launch commercial services in 2010.
