NTT DOCOMO has launched Xi, a wireless connectivity service in Japan, based on the Long Term Evolution (LTE) technology, scheduled on 24 December 2010.
The company said that Xi will enable mobile data communication at a maximum downlink speed of 75 Mbps, or about ten times as fast as its current FOMA 3G service.
Initially, the company will sell Xi data terminals for connection to mobile computers, beginning with the USB-type L-02C and voice calls using Xi will be available within the fiscal year starting in April 2011, when it will begin launching LTE-compatible mobile phones.
The Xi service will be initially available in the Tokyo, Nagoya and Osaka areas, with other major cities and regions to be added thereafter.
The company said that at launch, two data-only billing plans will be offered: "Xi Data Plan Ninen" and "Xi Data Plan."
