Fujitsu, NTT DoCoMo achieve 120 Mbps downlink for LTE

Fujitsu and Fujitsu Laboratories said they have conducted with NTT DoCoMo a successful field testing for Long-term Evolution (LTE) using 4x4 multiple input multiple output.

The testing resulted in high-speed wireless transmissions in the range of 120 Mbps (using 10 MHz bandwidth) in the urban area of Sapporo, Japan - which is equivalent to 240 Mbps throughput using the 20 MHz maximum bandwidth that LTE allows.

These tests revealed that the adaptive switching used in MIMO multiplexing was effective in achieving stable throughput in outdoor carrier environments.
