The telephone is a communication device which provides a private line of two-way audio communication across great distances without requiring an expensive private wire or landline, or any voice or video transmission facilities. It is often considered the first mass-produced consumer device that enabled both voice and music on demand with a relatively small catalog of prerecorded content. It is the oldest consumer appliance still in common use.
In 1876, Alexander Graham Bell was the first to be granted a United States patent for a telephone device. Exchangeable snap-on receivers were added in 1892, so several people could talk on the one line and it was also great for social gatherings or areas where multiple phone lines were not available yet. The first telephones with ringer were made about 100 years later around 1950.
The most common type of telephone has an upright stand and a pair of cradles to hold the receivers. The classic rotary dial is still used on many phones today, even though more advanced push-button dialing has been available since 1968. The dial is still necessary because the electrical signals in telephone networks are transient and do not continue to be usable after a phone call is over.
The earliest telephones were two-way devices used for voice communication. It could be difficult to hear the other person at the other end of the line, which may have been problematic in noisy places like a party line or with multiple users on a mobile phone. The first attempt at solving this problem was probably in the invention of the "telephone amplifier" by Scottish inventor Alexander Graham Bell in 1876. Several patents were filed around 1900 for various improvements on that device, resulting in two sets of bell-shaped receivers, one for each ear; these early versions resembled radios as well as ordinary phones. This set is the first example of a telephone that may be seen as a complete consumer electronic device. The main body contained the ringer, dial and transmitter for the pair of earphones, causing it too to resemble contemporary radios.
The first mechanically-rotated dial was patented in 1891 by Emanuel Fritz. It was also possibly the first commercially successful receiver to utilize an electric bell instead of a diaphragm/electrode system for signaling reception. The bell ringers were one element in an automatic switching system that could connect a phone subscriber's circuit to any other in stock in a central city exchange, making long distance calls feasible for the first time, though this idea would only be actualized several decades later.
The first dial phones were installed in commercial buildings around the same time. Several large city exchanges were created in Europe, each serving tens of thousands of subscribers. An exchange would typically have a switchboard designed to handle tens to hundreds of lines, and wall-mounted arrays of pushbutton-operated telephones. Users would pick up a telephone, dial a number for another user at the same exchange and wait for the connection to be made automatically by the operator or central switching apparatus. Telephones used on a subscriber basis could be either party lines or private lines.
The first telephone switches and networks were all mechanical, operated by human switchboard operators. These switches and networks were conditioned to operate on the manually-operated party lines which required that the caller physically connect ends of a pair of wires together at both ends. The system was so cumbersome and awkward to use that it became common practice to provide each subscriber with a small telephone set in their home, as one might have a radio, for convenience. The earliest public dial phone systems were designed for these manual party lines, not the automatically switched network of leased lines which came later.
In 1928, Almon Strowger invented the automatic switchboard for privately run telephone exchanges. This was the first system to allow subscribers dialing into a residential network to have their calls automatically connected to the nearest telephone, without manually connecting the two ends. This reduced all of the operator's previous duties down to merely responding, "Number, please?" (the "que" part of "number, please?" being added later after considerable trial and error and disputed usage in manuals and publicity). A final touch was a system for prompting callers with questions about where in a busy household they were located: answering tones that would tell them whether they were at home or away from home.
The first truly mass-produced telephones were installed in homes during the late 1920s. The first mobile telephone, a car phone, was installed in Stoughton, Wisconsin, in 1946. The first transcontinental telephone line using microwave technology was opened in 1951.
In the 1960s and 1970s, the Bell System Divestiture brought competition to the telephone industry for the first time since its inception. With Bell's monopoly ended, "independent" telephone companies like Southwestern Bell Corporation (in Arkansas), Cincinnati Bell and Tele-Communications Inc. of California began entering markets across the United States.
Cellular telephones work in a very different way from older telephones that used an electric wire or cable to connect to other phones. The telephone signals used by cell phones run on radio waves instead of electrical wires. Mobile phones use multiple frequencies and multiple paths to communicate. The same system that transmitters use to communicate over the air (signal) is also used by the mobile phone to communicate between the handset and the network. This allows cellular phones to work in many different places from one company's network, thereby resulting in a national network of coverage rather than a single national network of coverage.
Due to technological advances in semiconductors, mobile phone technology has become much more compact and portable than it once was. This allows users to carry cellular phones with them more often and in more places than ever before.
Mobile phone technology has taken a leap forward since the smartphone was introduced in the early 2000s. More advanced and intuitive mobile applications have freed users from simply communicating via text message or by calling. Today, many mobile devices are built with Internet connectivity and are capable of performing many functions such as email, Internet browsing, GPS software, video streaming and even first-party application downloads.
Cell phones evolved into smartphones that can be used by any user to send and receive text messages, make voice calls, play games, access the Internet and perform other tasks on demand.
Conclusion
The history of telecommunication has undergone a radical change during the past decade. This is due to the development in recent years of new digital technologies that have changed the way we communicate, and which have also made possible a further evolution toward an integrated service platform for communication and information, known as convergent communications. New technologies have also made it very clear that traditional policies and regulatory frameworks are no longer adequate for this market.
Nowadays, convergent communication services provide multimedia messaging and other forms of messaging services via fixedline or mobile networks.
