The History Of Telecommunications Tulsa OK

By Marci Glover


Back in the days, for people to communicate, they had to be at close proximity to pass the information across. At a distance, the channels of communication available included drum beating and some signals. The scope of information that would be sent was narrow. Telecommunication was invented between the late 1830s and early 1840s which revamped the telecommunications Tulsa OK by providing a quick and convenient mode of communication amongst different people.

The new methods of communication that were invented were telephony, telegraphy as well as electronic mails among others. This involved transmission of electric signals through metallic cables over long distances. These cables were first laid to link the USA and the Great Britain passing through sea beds. These new methods were revolutionary in nature since they changed the communication industry completely in the entire globe at that time.

The main aim of laying a communication link between USA and the Great Britain was to facilitate an easy communication between the president of USA called James Buchanan and the queen of Great Britain known as Victoria. For this reason, the project could not afford to fail at all costs since the communication between the two leaders was deemed very important.

These cables however failed quickly and could not offer reliable form of communication between the USA and the Great Britain, which was heartbreaking owing to the huge investment that had been undertaken. More needed to be done in this area to ensure success in this area, and so the two countries remained committed to ensuring the communication link was up and running. It was until the year 1956 that the telephone link between the two countries was successfully set up.

A rather interesting form of communication invented by a French man known as Claude Chappe was designed to transmit messages from one place to another rapidly in the year 1792. The system involved setting up of a number of towers that were six miles apart. Operators located on top of these towers would receive a message and transmit it to the next tower. The transmission of messages was mainly through use of semaphores. The system lasted only up to 1880 when it was rendered obsolete by the now powerful telegraph system.

The first commercial electrical wire based telegraphs was invented in the year 1839 by Sir William Fothergil Sir Charles Wheatstone, which was an improved version of the already existent electromagnetic based telegraphy.

The development of the communication system had taken a good start. In the 20th century, more convenient system of communication was invented. This was wireless communication which required no physical link between the sender and recipient of the information. This mode of communication was invented by Nobel Laureate Guglielmo Marconi using radio waves.

As is evident, the communication industry has come a long way to get to its present status where it has literally reduced the world to a global village. This has been only possible because of the selfless and determined nature of the early scientists whose work was used as a basis of developing more sophisticated methods of communication.
