SoftBank Mobile has announced LTE trial results in Fukuoka with test speeds hitting 70Mbps using 1.5GHz belt
I will inform you that a Softbank mobile company begins as “Ubiquitous special district” project in December, 2009 the field proof experiment of the LTE system that uses 1.5GHz belt, and achieved the throughput of maximum descending about 70Mbps that is the maximum transmission speed of 3GPP standard in transmission bandwidth 10MHz.
This experiment is executed what in the area in Fukuoka Prefecture Northern Kyushu City Yahatahigashi Ward. under Northern Kyushu City and the foundation Kyushu human media creation center’s cooperating. The trial system was composed of an experimental base station of three games, and conformed to the LTE standard issue. Moreover, descending MIMO transmission with two antennas or less was used for the base station transmission and the mobile station reception respectively, and the transmission bandwidth of 10MHz or less was used.
As a result, it descended and the throughput of maximum about 70Mbps was achieved in an actual wireless environment in outdoor. This is descended by maximum transmission bandwidth 20MHz of LTE and corresponds to the throughput of maximum about 150Mbps. Moreover, it was confirmed to be able to shorten being able the real time transmission of rich contents such as 3D images and the online gamings compared with a present HSDPA method, and the transmission delay greatly.
Some sage advise when entering new turf; Stop, Look and Listen.. it’s also good to secure a local guide. Japan is the cradle of mobile civilization – we have been dedicated to this space since 2001 – trust our archives here offer some useful material.
