After reading the pdf, I'm still not clear: does this mean UAVs can operate in regular airspace (above 400 ft) with proper licensing, or are they still (for now) limited to under 400 ft, and away from populated areas?
UAVs (UASs) can operate above 400 ft with a Certificate of Airworthiness (or similar.) However, the FAA will not yet issue you one, as they don't yet have to rules to do so.
UAVs that qualify as "model aircraft" can operate in that domain, as they always could. But now commercial use doesn't automatically turn them into license-requiring UAVs.
