James Clerk Maxwell’s discovery of electromagnetic waves was proven experimentally by Heinrich Hertz. From then on here were numerous attempts to use electromagnetic waves for communications. A young Italian, Guglielmo Marconi, arrived in Britain and worked with the Post Office to gradually extend the radius within which radiation can be detected to ...

Beyond the facts that they recur in welldefined cycles and that they affect certain of the earth's latitudes more than others, little but theoretical knowledge exists about the nature of sunspots and the sometimes concomitant magnetic storms. However, almost inadvertently, modern telegraph systems are being immunized against them by such innovations as

AbstractThis paper surveys the emergence of the era of electrical communications, from its beginnings in the 1830s through to the end of analogue technology. The electric telegraph soon became an essential and visible business tool with its network of poles and wires, but it is argued that, as each system was supplanted by the next, the evidence of its
