LTE-Advanved (LTE Advanced) realizes higher speed communication than communication using optical fiber line (about 100 Mbps) though it is mobile communicationA standard selected as the 4 th generation mobile phone (4 G) communication system together with WiMAX 2is.

Its target performance is 1 Gbps maximum for downlink and 500 Mbps maximum for upstream. At Wireless Japan 2011Exhibit of prototypes of base stations and mobile stationsIt was also done and a demonstration was done as well.


NTT DoCoMo's vice president Tsujimura was held in March 2012Mobile IT AsiaIn the keynote speeches,I would like to finish the development of LTE-Advanced by FY 2015 and start service after FY 2016I was talking.

Regarding this matter, when I contacted the publicity of NTT Docomo from the editorial department of GIGAZINE, as I said before, as planned by Tsujimura vice president, we planned to finish development by 2015 and start service after FY 2016, but 2015 It was said that the service was started during the fiscal year.

In the article of the Asahi Newspaper, the start time is written as "2015", but in short, "during 2015" and the technical name "LTE-Advanced (advanced)" is used .

NTT DoCoMo plans to raise the maximum downlink speed to 150 Mbps for Xi during FY 2013 as well. Other companies' high-speed communication services are up to 112.5 Mbps, etc., and it seems that speeding up mobile communication will advance faster than previously thought.
