Japan’s Ministry of Internal Affairs and Communications issued TDD 3.5 GHz licenses. SoftBank, Docomo and KDDI will each obtain a 40 MHz spectrum.
The three telecom operators filed their applications for 3.5 GHz licenses in October 2014. They reportedly pledged to invest $3.6 billion in building 3.5 GHz base stations in next five years and start network construction no later than March 31st, 2016. The network is expected to be commercialized by the end of 2016, covering 50%~55% of mobile phone users in Japan.
The Japanese government hopes to offer the 1Gbps ultra high-speed wireless broadband access through the 3.5 GHZ frequency band, which asks operators to bring the advantages of LTE-A key technologies, such as carrier aggregation and multi-antenna, into full play.
It is believed that the launch of TDD 3.5GHz licenses will greatly speed up the development of wireless broadband in Japan, and moreover give a strong boost to the development of TD-LTE technology and the global 3.5GHz industry.
