From the invention of the telephone (1877), till 1950, the range was short because of the line attenuation. These lines were made of two bronze wires of 5 mm diameter suspended from insulators fixed on wooden potes. The cables were buried! At regular intervals, electronic tubes repeaters were set up. Transmissions and possible ranges improved in a remarkable manner. The first free space microwave links were set up. But, very quickly, appeared an important achievement. F.D.M. (Frequency Division Multiplex) links.This increased the capacity of links and at constantly decreasing prices.
