The companies have aimed to achieve 1Gbps because the conventional throughput of 100Mbps is inadequate for base stations where there is a high concentration of communications traffic in small areas, including the hotspot environment. The three companies reported the results of their simulation at “Mobile Communications Workshop” held at Yokosuka Research Park.
