NTT Docomo said Friday that subscribers to Xi, its extra-high-speed LTE mobile service offering a maximum downlink of 100 Mbps, surpassed 10 million on Feb 18.
Subscriptions to Xi have been growing rapidly since its launch as one of the world’s first commercial LTE services on Dec 24, 2010. Subscribers reached one million in December 2011 and then quickly topped five million in August 2012. Docomo supports its LTE customers with a wide variety of advanced devices, including 32 smartphones, six tablets and seven data terminals so far.
Docomo said it will continue to expand LTE coverage and raise data transmission speeds, including by making the 112.5 Mbps downlink available in 22 cities by March and more than 50 cities by June. LTE base stations offering a 75 Mbps downlink, double the current speed in many locations, will amount to 4,000 by March and then jump to 10,000 by June. Docomo also plans to introduce a 150 Mbps downlink service before March 2014.
