Who should manage the spectrum??
There are some struggle as to 700MHz spectrum in USA. Story is simplly birthright owner(taditional player) vs new commer, namelly Verizon vs Google. Currently 700MHz spectrum is owned by TV broadcaster and planned to be reframed and auctioned off as part of the switchover to digital broadcasting.
Same type of struggle will be occuerd all over the world. It's true that there is a trend toward birthright owner have a disadvantage.Definitely Japan is not exception. As to WiMAX 2Ghz spectrum,Ministry of Public Management WiMAX isset limits existing Mobile carriers to invest less than 30% to WiMAX operating company. The conclusion will be comming soon.
Anyway, Google claimed that in principle for usage of spectrum, end user can use their handsets with any network they desire, and download and use the lawful software applications of their choice. In this logic, exsiting carrier is inferier, but new commers once owned the spectrum, they will know the difficulty to handle it.
