The telephone revisited
LASZLO SOLYMAR · 1999
Abstract The telephone made great strides ahead in a very short time. By 19n, as mentioned in Chapter 5, it was possible to make a call from New York to Denver, 4300 km away, but obviously that was not far enough. Ambitions were much higher: firstly, to span the continent from New York to San Francisco, secondly to establish telephone connections between the US and Europe, and finally to enable people to conduct conversations between any two points on Earth.
