Telecommunication systems are unique in the range of distances over which their relevant processes take place. This was already true in the middle of last century, when centimetric devices such as vacuum tubes would process signals to be transmitted over a few kilometers over metallic cables, thus integrating processes occurring over a range of five orders of magnitude in reach. Nowadays, this range has increased by at least ten orders of magnitude, as some processes occur over nanometric structures such as quantum dots; and signals may reach thousands of kilometers on Earth and even millions of kilometers in interplanetary communications.
