Up until just over a years ago, the whole world was still utilizing analogue radios, limited to transmission strength changes and a host of other difficulties in communication. The instantaneous communication we have today is due to an eager search for a better means to communicate than analogue, and many technological development must be carried out in order to get us to this date. By making our own larger ranges of frequencies, we now have improved the way the world communicates, with more progress on the horizon. To know how we reached this point, it could help to know the way we were.
Signal Transmission And Analogue Radios
For many years, the whole world used analogue transmissions as the preferential way of sending and receiving telecommunication signals. Sent in the form of sound waves, the transmission would be duplicated continuously until it was picked up by some type of receiver, like analogue radios. Such signals were restricted to one wave for every channel, and if the channels became overloaded with such transmissions, millions of bits of data could potentially 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 and telephones, other inventions were produced or improved, getting some of the pressure off. This is how cellphones occurred, and the higher speed bandwidths used in computer communications.
The Main Problem With Analogue Communication
Because analogue radios and other devices were still dependent on those sound wave signals to communicate, the next stage was a search a way to conquer the major problem of analogue communication: clarity. When a sound wave is sent, it only duplicates the original transmission over and over, till it reaches a receiver. Throughout the length of time prior to reaching that receiver, it is continually raising it's signal strength, just like a tidal wave builds up signal strength en route.
As the transmission strength increases, so does the possibility that static and other sounds will be dragged along with the repeating wave. Once that wave would reach analogue radios or any other receivers, it could have become so garbled with other sounds that the original message is now lost. A way had to be found to strengthen the signal for transmission, while blocking out unwanted noise on the way. The first place they looked to was digital communication, now restricted to computer signals.
The Conversion To Digital
Once they started looking at the technology in back of computer communications, it was discovered that a crucial factor in the clarity of this format was the digital conversion of data just before transmission. Once examined using analogue radios, the transformation of each sound to it's binary format had improved the quality of the sound that was received, and the level of static sound was reduced a great deal.
The drive was on to develop the technology to adjust the system for world-wide communication. When completed, converters were created to help adjust the analogue signals into digital format, help raising the number of communication channels for transmission. Unfortunately, this also meant the end of utilizing analogue radios, however they still have an important component in the history of digital communication.
