	Dear Group,

	The transmission and reception of signals in the optical, or light
domain ... but not using fiber or other light guides is called 
	"Free Space" communications.   This has been a method known since
the mid to late 1800s ...and systems have been part of electronics design
from the time of vacuum tubes onward.
