World Radio System, Now
Under Way, Gives Promise
of Success.

Development OF globe-circling sys.

what some claim to be the speediest
and most efficient wireless service in
the world. This has stimulated Amer
lean interests to an investigation of
the possibilities in beam" wireless,
which is the transmission on high fire.

Quires less power for better results
than ordinary radio. AS described by
Harold Hayes, assistant supervisor of
radio of the Department of Commerce,
the radio beam" may be likened 10
the spoke of wheel.
Under ordinary transmission, the
radio wave emanating from the trans
mitter radiates i'm all directions. The
beam" system concentrates the wave
impulse into a narrow path, and it
leaves the transmitter just as spoke
points from a hub. Using the same
power, the concentration on the dircc.
tional impulse gives it IS times more
energy than if the wave radiated in
all directions.
