From Wikipedia:
Compared to lower bands, radio waves in this band have high atmospheric attenuation; they are absorbed by the gases in the atmosphere. Therefore they have a short range and can only be used for terrestrial communication over about a kilometer.
and
While this absorption limits potential communications range, it also allows for smaller frequency reuse distances than lower frequencies. The small wavelength allows modest size antennas to have a small beam width, further increasing frequency reuse potential.
It sounds like the absorption will be a feature, not a bug. This will allow many more antennas in a city like situation. It won't be any good in rural areas, but I don't think it is meant for that.
