We are constantly reading of the enormous possibilities of the radio, says a writer in the London daily news, but they are often over estimated. A popular idea, for instance, is that the time will come when we can step into a radio phone office in London, talk to someone in Australia and see them at the same time. That is a physical possibility, but not so all the other conjecture which we hear every day. Perhaps the one which appeals to the imaginative mind most often is that soon the ordinary landline telephone will be obsolete and everyone will carry a pocket radio phone by which they can call up whom they like.
It is common knowledge among wireless amateurs that the only way for two neighboring wireless stations to transmit at the same time without causing interference is by using a different wavelength. At present there are nearly 1,000,000 telephones use in England and the number is steadily growing. If Pocket radio phones were to be substituted, it would mean that to avoid interference nearly 1,000,000 different wavelength would have to be located. It is only possible to adjust engager wavelength within or 20 miles.
The great drawback in radio and one which seems impossible to overcome is it that the eather through which the wireless travels will only hold a certain amount of business and no more if more than it’s limit is transmitted interference is inevitable.
