First semaphore systems appearing in Europe
In 1792, Claude Chappe, a French engineer developed the first network of optical telecommunication (or semaphore) between Lille and Paris. This was accompanied by a line between Strasbourg and Paris. -
First Reported Transmission of Human Voice
A number of inventors filed patents in the early nineteenth century claiming to had attained transmission of the human voice. Such as Antonio Meucci, inventor in Italy. Their innovations, though, were not really functional, so they were not produced as commercial products. -
The Telegraph System
Telecommunications originated in 1844 with Samuel Morse's popular breakthrough in the telegraph system. TIn theU.S. for 3 years The visionary Washington Post Office led the line to Baltimore. By then other private telegraph companies had formed (the first to communicate with New York and Philadelphia) and were expanding rapidly. The expansion of telegraphs paralleled and enabled the growth of the American railway network. -
The telephone was invented
Telephone was developed by Alexander Graham Bell. Three hours after Bell Elisha Gray files a patent application. In the next 11 years over 600 patent cases were filed. Settled in favor with Bell. Bell is selling Western Union its patent for $100,000. I got the following item from Warren Bender, of A.D., years ago. Petit, Inc. Warren released it in an early issue of IEEE Systems Transactions, -
The first telephone exchange
The first phones were operating in between two fixed points. For example, a business could have a line in between two offices. The principle of telephone company, nevertheless, was nearly as old as the telephone itself. In the mid-1870s, Hungarian Tivadar Puskás first planned a telegraph exchange, then rapidly adapted his designs for the newly invented machine. Based on his work, Bell's subsidiary company in New Haven, Connecticut, established the first commercial telephone exchange in 1878. -
Period: to
Early long distance
Physics bounded early long distance lines Call quality will decrease for each mile of track. It would be too long and the call will be muffled. Nonetheless, in 1880 AT&T Long Lines was established to create a transcontinental telephone network in the USA. By 1892, AT&T's network expanded from New York to Chicago, and the first undersea telephone cable between London and Paris was opened. -
The Bell system was created
Next year, Bell created the corporation that for more than a century would continue to dominate North American telecoms: The Bell Telephone Company. Yet Bell wasn't sure about the route. Thomas Edison invented his own superior telephone and established a short-lived competitor to Bell, the American Talking Telephone Company, with Western Union. -
Rotary dial and automatic exchange
Relatively early developments were the rotary dial telephone and the automated telephone system. Designed by Almon Brown Strowger, an undertaker in Kansas City, it saw acceptance only from non-Bell System networks and outside the US. Due to reliability problems, AT&T rejected the automatic exchange and only embraced automatic switches when they had built their own system in the early 1920s. -
Transoceanic phone call
In 1866, service began on the first viable Transatlantic telegraph connection, consisting of two separate cables, each capable of carrying one message at a time. The cables were barely able to carry morse code without amplification let alone speech. Marconi sent the first message over the Atlantic via radio in 1901. -
Microwave on-land
Cable was expensive. New York-San Francisco's first line needed close to 3,000 tons of copper and 130,000 poles. Radio had proven successful for long distance telephone communication but had limited capacity and privacy as a broadcast medium. Microwave communications were highly focused and therefore suitable for point-to-point contact, unlike lower frequencies. Communication experiments using microwave radio had begun in the 1930s, -
The first transatlantic telephone cable
Telegraph subsea cables circulated the globe, and subsea short distance telephone cables linked island nations to neighboring continental partners. Nevertheless, it wasn't until the mid-1950s that a transatlantic telephone line was feasible with cable engineering. Coaxial cable, synthetic insulation and vacuum tube repeaters made it possible to open the first link–TAT-1–in 1956. it had room for 35 telephone calls and 22 telegraph networks simultaneously. -
The internet was born
ARPANET, the predecessor of the modern internet, was the US Department of Defense's experiment on robust computer networking. The first link with UCLA and the Stanford Research center in Menlo Park, California, was founded in 1969. -
First Telephone Call
With an AT&T service built for use in automobiles, mobile telephony dates back to 1946. Despite decades of progress, these radio telephones suffered from congestion and interference from the network. It wasn't until cellular telephony emerged–which enabled mobile devices to move from one tower to the next–that issues of power and range would be solved. In 1973 Motorola engineer Martin Cooper made the first call from such a cellular telephone. -
First commercial cellphone network
Since the late 1940s, radio phones had been commercially available but they were severely limited by the size and amount of simultaneous calls that could be carried. In 1979, Japan's NTT launched the world's first industrial mobile telephone system, whereas in 1983 Ameritech introduced the first US service. -
First internet voice communication
Compact disks, fiber optic networking, the new networks of cell phones: they all converted sound into digital information and then turned it back into sound. The groundwork for voice communication was laid over the internet and Autodesk engineer Brian Wiley traveled to Europe in 1991. He wanted to find a way to keep in touch with coworkers based in the U.S. and thus developed NetFone, the world has ever known first digital voice calling app. -
World's first text message
Software engineer Neil Papworth used his PC to deliver the first text message of the planet. This said "Merry Christmas" and used part of the GSM messaging protocol for new voicemail messages and related network messages. -
iPhone was invented
Steve Jobs unveiled the first iPhone at the Macworld convention on January 9, 2007 and received significant media attention. Jobs announced the release of its first iPhone later that year. The first iPhone was released June 29, 2007. -
The telecoms API
The telephone has evolved tremendously from that first conversation between Bell and Watson in 1876 till today. What was a concrete box, limited by the quality of the network, is now much more nebulous. What is meant by "telephone" is now something like a conventional landline call, which could be a pocket supercomputer or a call made over the internet. Over the past 10 years, communications APIs, have taken us on the next phase in telecommunications evolution. -
