Alexander Graham Bell, in 1878, wrote: "I believe in the future wires will unite the head offices of telephone companies in different cities, and a man in one part or the country may communicate by word of mouth with another in a distant place". True enough, since their invention in the 1870s, telephones are among the most important tools in telecommunication today. Today, telephones come in a variety of systems and among the most popular are cellphones. These types of phones, often carried in their leather mobile phone cases, are used virtually by everyone all over the world.
The great improvement in the world's telecommunication system of the world happened on March 10, 1876 when the first telephone was invented by Alexander Graham Bell. Originally the idea of the telephones started when Michael Faraday discovered that vibrations of metal could be converted to electrical impulses, and when Johann Philip Reis invented an apparatus that changed sound to electricity and back to sound in 1861. With all these ideas, Bell worked on his experiments with the electrical signals of the telegraph, hence he invented the telephone.
After the telephone was introduced, different improvements on it were done. Among the popular telephone improvements was the invention of the cellphones which are often seen carried on leather mobile cases. These cellphones are now considered as the most popular means of communication. Other than the invention of the cellphone, the three different telephone systems were also discovered, namely, the landline telephone system, cellular wireless telephone system, and the internet protocol system. The landline telephone system which is a part of the POTS or the Plain Old telephone System that uses full duplex system allows both people on the call to talk at the same time. It is a system that employs standardized equipment and a lot of people prefer using it, because it produces predictable sound quality.
Second, the cellular wireless telephone system is the system which is required for mobile phones. Unlike the landline telephone system, the cellular wireless system carries not only voice but also data. On the other hand, this system also allows full-duplex system like the landline; however, it uses radio frequencies rather than copper wire. Lastly, the Internet Protocol telephone system or the Voice-over Internet Protocol (VoIP) is a system that offers existing Internet service with the use of cable service or DSL broadband to connect to a network.
Among the three types of telephone systems, among the most popular is the cellular wireless telephone system especially that cell phones are deemed a necessity in today's world. Carried in leather mobile phone cases, cell phones can be used virtually anywhere in the world depending on one's network capability. Today, cellphones also come in a variety of types. Among these are Personal Digital Assistants (PDA) or Smartphones, touch screens, slider phones, flip phones, and budget cellphones.
The world of telecommunication has indeed been significantly since the invention of the telephone. With various improvements and modifications to Bell's invention, said industry still continues to grow. As such, one may expect more gadgets of communication will be carried in leather mobile phone cases and not only cellphones.
