However, it turns out that the MIC gave it away based on need. After evaluating the state of network congestion of each of Japan's four carriers, who all applied for it, SBM was awarded the band. This will help with their LTE plans. [Update: SGM deployed 900 MHz for 3G.] Emobile would have also liked to have had it, as they not only have no low frequency band, but also have an exotic frequency not used by other carriers. It will be interesting to see how this effects Emobile's LTE plans. It doesn't even overlap with AWS used by US T-Mobile.
Below is how the higher-frequency bands are distributed between Japanese carriers. It becomes obvious why US T-Mobile handsets work with Docomo.
|The overlap is just an idealized IMAGE. The curves are just a gaussian fit to a uniformly distributed histogram of random numbers between the ranges of each band's up and downlink. I have no idea how power is actually distributed within the spectrum.|
