The Wide Area Network can trace its roots to this invention

In the late 1950’s, engineers at Bell Labs came up with a revolutionary technology that paved the way for computer networks—the modem. The modem, which stands for MOdulator and DEModulator, encodes analog signals into digital ones so they can be transmitted, then decoded on the other end. In a word, it’s a translator. Modems were actually invented in the late 1940’s, but it was the engineers at Bell Labs who enabled them to connect computers. They were originally created to transmit radar signals over the the existing telephone infrastructure.

The modem enabled computers to communicate over existing phone lines. Prior to the modem, communications between computers required dedicated, highly expensive circuits. It was cost-prohibitive. By using a transport medium that was extensive and connected any phone in the country, the modem enabled computers to communicate, regardless of their location.

The modem carried on the tradition of code translators, such as Morse Code, which was invented by Samuel Morse in the early 1800’s. In Morse Code, series of dots and dashes represent each letter of the alphabet and were sent across telegraph lines. The first Morse code transmission was sent from Washington, DC, to nearby Baltimore, MD. In 1858, a transatlantic telegraph line was dropped in the Atlantic Ocean and enabled messages to be sent between the U.S. and England in a matter of minutes. Prior to that, it could take up to 2 weeks.

As we all know, however, technology changes fast, and the 1900’s were no exception. The telegraph lines were replaced by telephone lines later in the century.   

If you’d like to revolutionize your WAN communications, you’ve come to the right place. MetroNet’s WAN solutions require no additional technology and provide wide area connectivity through MetroNet’s 100% all fiber network. With cost-effective pricing that’s not mileage-based, connecting to the most remote locations will seem as fast as communicating with ones across town.
