RADIO TELEPHONY

BEAM PROMISES CITEAPNYSS. Wireless telephony across the Atlantic over a beam system which would not only be freer from interference than the present service, but also could be furnished for about a fifth of the present cost, was predicted by Senator Marconi in an interview in London on Lebruary 3. "We are devoting a good deal of attention to the super-imposition of telephony on the telegraphic signals now being sent over the beam system," he said, "The results have been so satisfactory as to warrant the hope that in a period of months we shall be able to take advantage commercially of this important development. "Telephony under these conditions would be very much more economical than at present. ‘The financial return from the telephony would pay largely for the operating expenses of the telegraphic service and make it possible for us to give wireless telephone service certainly at a much cheaper rate than the present 75 dollars (£15) for three miuutes. "The greater the success of our experiments, the greater reduction we may be able to make in the charge. It might be less than 15 dollars (£3) for three minutes."
