RADIO TELEPHONE
SERVICE PLANNED
"A. T. & T. Establishing Sys-
TEN of Communication From
Ship to Shore.

Final preparations for the establish
ment Of ship-to-shore telephone serv-
ice by radio, under which every one OF
the 100000 telephones within the
United States would be available for
direct connection with vessels on the
high seas, are being made by the Amer.
lean Telephone & Telegraph Co.
The Leviathan, American queen of
the seas, already has been equipped for
the service, and further experiments
are being carried out preparatory to
the actual Inauguration of service. Only
experimental licenses have been granted
for it, however, but actual service may
be carried on to ascertain the feasibil-
ity of telephone communication from
land to vessels en- route on the oceans.
The Federal Radio Commission has
granted the application of the A. T. & T.
for the assignment of channels to be
employed in the service. which 1t hopes
TO- establish by next Fall.
Commission Grants Channels.
Recently the commission granted four
channels in the mobile bands for the
experiments, but the A. T. & T. re-
Quested an additional channel and the
substitution of one which had been as
signed it. The commission has APP
proved the request, since 1t Will facll-
itate the preparations. Channels In
different bands are required, so that
continuous contact between land and
the vessel may be had, because particu-
lar channels are adapted for commune
cation only over recognized distances.
For example. channel in the band
from 5000 to 1000 kilocycles may be
employed for only few hundred miles,
whereas to keep the conversation I'M
disturbed when the vessel reaches Eu-
y1t
mel in the 1000 to 10000 kilocycle
band is required.
After two weeks of intensive work
since 1t reconvened, the Commission
has rendered decisions on large batch
of pending applications, OF which the
A. T. & T. request was one. Forty ap-
plications of the Universal Wireless
Communications Co.. Inc. for trans
oceanic frequencies to augment its au-
thorized domestic radio-telegraph serv-
ice were designated for hearing some
time in December Universal filed for
these frequencies with the announced
intention of competing with the Radio
Corporation Of America in world radio
communications. Forty continental ra-
dio-telegraph channels were granted
Universal, with which 1t must inter-
connect 10 cities and serve the public
with a Geographic service by radio IN
competition with the established wire
lines.
Forty Stations Sought.
Universal states in its applications
that each of the 40 stations sought
would be Of $4,000 watts power. They
would be located along the Atlantic and
Pacific seaboards and link up with the
domestic network 1t now has under con-
structior. r. c. A. already has trans
oceanic service reaching. 80 foreign
countries and is authorized to augment
it with a limited domestic service serv-
ing less than q score of cities with but
is channels.
Virtually all of the commissions de.
cisions dealt with communication chan
nels, but four miscellaneous applica-
tions relating to broadcastlng were oe-
MED because the applicants failed TO
appear at hearings scheduled before the
commission.
The Mackay Radio Telegraph Co. was
granted construction permits fora new
coastal station at Bar Harbor. Me-, 10
communicate from shore to ship ana
utilizing a series of frequencies in the
mobile band. Mackay also was author
lied to construct Standby transmit
tiers at Honolulu and Palo Alto, Call
which may be employed in communlca-
ton on any Of the So frequencles allo-
Gated the company for tranSoceanlc
communication for one year, after
which specified frequencies must be
designated for communication between
particular points
An application granted by the COM
mission Of particular interest to radio
engineers is that of Wired Radio, Inc,
of New York for permission to expert
rnent with rebroadcaSting on what 1t
claims to be "three-phase" system.
The company. which proposes to com
pete with space radio" by offering a
choice of programs to listeners sent
them along the power of telephone lines
entering their homes, claims to have
exclusive patents which will make pos
sible the mission of three broadcast1ng
signals on the same standard width
channel. The "three-phase" system, 1t
explains is to send three different pro-
grams from different transmitters, one
following the other at such speeds that
the signals are not jumbled or marred.
1t would be phenomenal advance Tor
broadcasting if accomplished.
