There are different technologies being used.  The Vivato solution
essentially adds power to the signal.  While that's a simplistic
explanation, but it is accurate.  The Tropos solution uses a peered mesh
network architecture versus a star.  This is the same network design that
enabled the popular US network deployed on the west coast called Ricochet.
While the company failed by overreaching in deployments, the network and
technology was widely popular in the marketplace for data among mobile
professionals.

Yes.  Nothing special is required.

Wi-Fi is the certification label for 802.11 standards compliant equipment,
so of course it uses radio and not microwave.

Yes, these products must be approved by the FCC prior to being sold in the
US.  The UWL (underwriters laboratory) must approve the compliance of
products for health and safety in the US.

There are projects going on all over to bring Wi-Fi and it's increased
bandwidth to market.  I'd look for some interesting developments coming out
of Europe as well.
