It needs to be in the infrared spectrum at least to be useful for smart dust, otherwise the package size is still dominated by the size of the antenna. Even mm-wave radar is marginal here.

So... smart dust powered by the sun? Cool!
Okay if you take dust literally. The important part is that the particles fly. Like dandelion seeds.
