Japanese broadband provider UQ Communications, KDDI’s WiMAX joint venture with Intel Capital, has announced that it has passed the ten million subscriber milestone on 30 April 2015. The operator disclosed that subscriber uptake has increased at a rapid pace following the introduction of its WiMAX 802.16m network, dubbed ‘WiMAX2+’, for smartphones in May 2014. Further, UQ Communications stated that it has expanded the area of mobile internet coverage in Japan, while also increasing the download bandwidth speed of the WiMAX2+ service to 220Mbps with the ‘Ya-Baisoku’ service.
As previously reported by CommsUpdate, in July 2011 UQ Communications achieved downlink transmission speeds of over 100Mbps in what it described as the world’s first WiMAX2 field trial. The pilot, which was held in Otemachi, Chiyoda-ku, Tokyo, was staged in cooperation with Samsung Electronics and used 20MHz of spectrum in the 2.6GHz band. IEEE802.16m is approved as an IMT-Advanced technology by the International Telecommunication Union (ITU).
