|WHAT THE INVENTOR SAYS: It has already been proven that distance does not affect the wireless transmission by the Hertzian wave.
My telephone messages from fifty feet to seven miles are a further demonstration of this fact. The first application of my wireless telephone will be for marine service. Wireless telegraphy has been used commercially on about 250 ships up to date. As my telephone will work as far as any wireless telegraph instrument after some development I intend to apply it for the same service. In time of war, every battleship fitted with a wireless telephone will be able to get any particular ship within its range without the danger of messages being intercepted.
An ordinary wireless telegraph instrument requires an operator. By using my telephone the officer in command could carry on the conversation personally. In a great many cases my wireless telephone could be better adopted than the ordinary wire telephone. For instance, no person desiring an absolutely secret telephone communication between Oakland and San Francisco would have to go to a tremendous expense to secure it. At a nominal expenditure of money two wireless telephone stations could be erected and maintained, assuring absolutely secret and uninterrupted communication between these two points. The field of my wireless telephone is greater than that of the wire telephone, in view of the fact that it can be used in isolated places.
The following is a summary of the uses to which my telephone will be applied: Marine service, lumber camps, mines,
ferry-boats, lighthouses, mountainous districts, desert lands, balloons and our future air ships; in fact, in all places where it is either impossible or too expensive to apply the ordinary telephone.
