LTE (Long Term Evolution)

Japanese

The concept of LTE was proposed by NTT DOCOMO as Super 3G in 2004 and it was standardized in 3GPP (3rd Generation Partnership Project), an international standardization organization. As a specification, LTE aims to provide the high data rate service of approx. maximum 300 Mbps in the downlink with 20 MHz bandwidth. It also realizes significant reduction in connection and transmission delays. Further, to improve spectral efficiency, technologies such as MIMO(Multiple Input, Multiple Output) have been introduced and OFDMA(Orthogonal Frequency Division Multiple Access) has been adopted as the downlink access system.
