Japan-based NTT DoCoMo announced today that it plans to begin testing on an experimental "Super 3G" system for extra-high-speed data on mobile devices.
The country's largest mobile carrier said that it hopes to achieve an impressive 300Mbps down in its tests over the wireless network. The company has already begun accepting proposals from suppliers and hopes to implement the Super 3G system in Japan by 2009.
The company said that it planned to start experimenting with Super 3G in an indoor setting with only one transmitting antenna and one receiving antenna. From there, NTT DoCoMo plans to expand the experiment by using four Multiple-Input Multiple-Output (MIMO) antennas on both the transmitting and receiving side. The ultimate goal will be not only to achieve 300Mbps down but also to look at how well handovers will be handled between towers.
