DoCoMo's Smart Vertical MIMO achieves 1.2 Gbps with single-size antenna

Japan's NTT DoCoMo laid claim to what it said was the world's first transmission exceeding 1.2 Gbps in a field test using a single-size antenna incorporating a new transmission technology for LTE Advanced systems. The operator's Smart Vertical MIMO transmission technology actively groups vertical antenna components according to reception quality for mobile devices in the transmission area. This enables a single-size antenna to achieve throughput equivalent to that of a four-antenna system. "Smart Vertical MIMO, a key technological development for the planned deployment of DoCoMo's LTE Advanced network by the fiscal year ending March 31, 2016, reduces the cost and space of installing antenna equipment and improves spectrum utilization efficiency," the company said.
