Use of carrier aggregation technology will enable DoCoMo's LTE-Advanced to achieve its ultra-high-speed downlink.
February 27, 2015
TOKYO -- NTT DOCOMO, INC., a personalized mobile solutions provider for smarter living, announced today that it will launch its LTE-Advanced next-generation mobile communication service featuring a Japan-best 225Mbps maximum data-transmission speed, aiming at March 27.
The use of carrier aggregation technology will enable DOCOMO's LTE-Advanced to achieve its ultra-high speed downlink, which will be further accelerated to a maximum 300Mbps towards the end of the next fiscal year ending in March 2016. The maximum uplink will be 50Mbps.
The DOCOMO LTE-Advanced network will launch initially in 22 prefectures, including Tokyo, Nagoya and Osaka. Nationwide availability is expected by March 2016.
Two DOCOMO mobile Wi-Fi routers will be available for the service—the Wi-Fi STATION HW-02G, which is now on the market, and the L-01G, which is scheduled to launch in March. DOCOMO is also preparing to expand its lineup of compatible smartphones soon.
A unique feature of DOCOMO's LTE-Advanced service will be its introduction of Advanced C-RAN, a network architecture that efficiently increases radio capacity and maximum transmission speed simultaneously especially in high-traffic areas.
