2008 ., Softbank Mobile 1.5GHz frequency band operation on the plans for HSPA +, to market in 2010.

and compared to the other two mobile operators, Softbank have chosen another route. With advanced technology or 3.9G technology called HSPA + compared to select the former Softbank. The reason to make this choice because the direct costs of all aspects of LTE are too high, LTE chips are too expensive at the same time to overcome compatibility problems, but efficiency in the use of frequencies is the same with LTE. Softbank said it does not rule out the future possibility to upgrade to LTE.
