Abstract
THE achievement in wireless telephony recorded in the daily. Press during the past few days is by no means unique. It is reported that Mr. Daniels, Secretary of the U.S. Navy, successfully telephoned a wireless greeting to President Wilson on board the George Washington when the vessel was more than eight hundred miles out at sea. According to a paper presented before the American Institute of Electrical Engineers, wireless and wire telephone systems can be linked so that the human voice will perform one lap of its journey over wire and the next lap through the ether to its final destination, while the replying waves will travel the air waves first and then proceed on wire. The operation of transferring sound from wire to air can be accomplished by a device similar to the repeater now used in long-distance telephony. Latest developments in connection with the wireless telephone would suggest the latter as an excellent supplement of wire systems. As a rival, however, it has not yet reached the stage when its claims can be considered seriously, partly because of the lack of secrecy involved in its use.
