NextNav is city-wide navigation. It looks like beacone can cover a few miles which makes sense with the frequency. It can also work indoors.
Navigation system like that is useful for more accuracy or when GPS has problem. But not at the expense of 900 MHz band for other useful things. I'm surprised that they can't find an awkward slice of low-band that mobile provider would get rid of or lease.
