Fortuna, there’s only 2 MHz in the Guard Band and Expansion band combined in the 800 MHz block.
Read the header of this forum to see what the company disclosed in the January 2019 corporate update.
They have more than 2 MHz licensed, which means they have additional spectrum in the safety band or interstitial PLMT band.
The thing to look for is population coverage. In January they only covered 175M, but we know the applications started being accepted in July for the majority of the rest of the population.
Spectrum that IOTA owns/controls is not cellular and cannot support high data rate transfers. It is very low bandwidth. This is fine for communicating text, but not graphics. BUT, it can communicate long distances which is a boon. For lower bandwidth IOT applications this spectrum makes the most sense from a cost standpoint.
