Up until just over a decade ago, the whole world was still using analogue radios, restricted to transmission strength changes and a host of other difficulties in communication. The immediate communication we've got today is due to an eager search for an improved means to communicate than analogue, and many technological advancement must be carried out in order to get us to this point. By creating our own larger ranges of frequencies, we have improved how the world communicates, with more progress on the horizon. To know how we got to this point, it could help to know the way we were.
Signal Transmission And Analogue Radios
For decades, the world used analogue transmissions as the preferential means of delivering and receiving telecommunication signals. Sent in the form of sound waves, the transmission would be duplicated continuously till it was picked up by some type of receiver, like analogue radios. This kind of transmissions were restricted to one wave for each channel, and if the channels became overloaded with such signals, millions of bits of data could possibly be lost without realizing it.
As demand rose for clearer communication possibilities, modern technology had to be first developed to handle it all. Thanks to the quest to improve or replace analogue radios, televisions as well as telephones, other inventions were created or improved, getting a few of the stress off. This is how cell phones occurred, as well as the higher speed bandwidths used in computer communications.
The Main Problem With Analogue Communication
Because analogue radios and other equipment were still dependent on those sound wave signals to communicate, the following step was a search a way to conquer the major problem of analogue communication: clarity. Whenever a sound wave is sent, it only duplicates the original transmission repeatedly, until it reaches a receiver. During the length of time before reaching that receiver, it is constantly increasing it's signal strength, kind of like a tidal wave builds up signal strength en route.
As the transmission strength raises, so does the possibility that static and other sounds can be dragged along with the echoing wave. Once that wave would reach analogue radios or other receivers, it could have turn out to be so garbled with additional sounds that the original message is now lost. A way had to be found to increase the signal for transmission, while filtering out excess noise along the way. The first place they looked to was digital communication, currently restricted to computer signals.
The Transformation To Digital
When they started looking at the technology in back of computer communications, it was found that a crucial factor in the clarity of this format was the digital conversion of data before transmission. Once tried employing analogue radios, the conversion of each sound to its binary structure had improved the quality of the sound that was received, and the degree of interference noise was dropped quite a bit.
The drive was on to develop the technology to adjust the system for worldwide communication. Once done, converters were made to help adjust the analogue signals directly into digital format, help raising the amount of communication channels for transmission. Unfortunately, this also meant the end of using analogue radios, but they still have a vital part in the history of digital communication.
