A new new spectrum, 1.5GHz band with with 15MHz bandwidth, will will be be used in in Others(800MHz,1.7GHz) will will be be also also used for for LTE.

The popularization of smartphones is accelerating the trends. DOCOMO s LTE launch and service Xi DOCOMO launched LTE service Xi (crossy) on 24 Dec as one of the first group of operators in the world. Performance in commercial network satisfies the original expectations. Further evolution to true 4G/LTE-Advanced LTE provides a smooth path to a true 4G, as DOCOMO originally thought with Super3G concept. Pre-history of LTE standardization Summary end
