Some ranges are usable for Industrial/Scientific/Medical (ISM), and there are exempt low power devices although I leave it as an exercise to the reader to find out which:
IR2030/7/2, wideband transmission systems that are not fixed can be used up to 40dBm between 57-71GHz. Fixed systems are allowed, but not within 6km of certain sites. You can also use it for tank probing radar under various situations. One of them is MOD Hebrides which is a large closed area for weapon system testing, another is Castlemartin training area, and another near Luffenham (no idea about that one). Presumably it interferes with military radios and at least two of those sites are used with live ammunition, so probably it's a safety thing.
61-61.5GHz is an ISM band, so it's unlicensed pretty much everwhere. This frequency range is heavily attenuated by oxygen, so it has inherently limited range and low risk of interference even at high emission levels.
60 GHz is unlicensed in the US. Bridgewave and others have been shipping 60 GHz band point to point outdoor radios since 2008.
71-86 GHz ("E band") is light licensed, which is easier and less costly to coordinate than the traditional 6/11/18/23 GHz FCC part 101 microwave bands.

Is 60GHz band unlicensed in US and EU?
Ish in the UK, see http://static.ofcom.org.uk/static/spectrum/fat.html

For example:

According to this it is:

Not in the US at least.

I believe that's what he meant, not [licensed] in the US at least.
