Since people use smart phones in daily life, the mobile traffic over the network is changing. The rich content such as video streaming with high quality becomes popular and popular, resulting in huge traffic. The 4G (LTE) system with high capacity, launched in 2012 and now under rapid deployment, may not be sufficient to cope with the explosion. KDDI, the second-largest telco in Japan, is accelerating R&D activities towards LTE-Advanced, including Multi-User MIMO, Small Cell Enhancement, and Small-sized Active Antenna for Multi-band Basestations. Also, KDDI has a broader view under the name of "3M strategy" which comprises "Multi- Network", "Multi-Device" and "Multi-Use." We believe that further network enhancement from "Dumb Pipe" to "Smart Pipe" is the key for user-centric smarter life. Related R&D activities backed by Big Data will be introduced.
