The WiFi Cell Phone & Why the Telephone Companies Hate Cell Phones with WiFi

The WiFi cell phone has been identified by cell phone carriers as an up and coming threat to their revenue streams. Their concerns are well founded. Mobile VoIP or VoWiFi has the potential to evolve into a serious problem for them. It's possible that millions of WiFi cell phone users will either terminate their contracts with carriers or scale down plan minutes.

There is a precedent and the cell phone carriers are well aware of it. They had the opportunity to witness the impact of VoIP on wire line carriers. They lost millions of subscribers and their core product "voice" was irreversibly devalued.
There are parallels between the history of VoIP and developments in the world of WiFi. Neither technology was taken seriously in the beginning, but both have now become mainstream. We initially became familiar with WiFi in our homes. Subsequently it was adopted by business and then continued to spread like a virus to hotels, airports, public libraries and hot spots. The net result is that millions of us have been exposed to the technology and feel comfortable using it. It's simple, robust and getting better all the time.

Last words

No contemporary cultural artifact embodies the genius and the disruptive excess of capitalism as clearly as the cell phone. Ubiquitous in most developed societies in Europe, the Americas and Asia, the cell phone has become a laboratory – some would say an asylum – for testing the limits of technological convergence. Less a telephone today than a multi-purpose computer, cell phones are game consoles, still cameras, email systems, text messengers, carriers of entertainment and business data, nodes of commerce. Particular age cohorts and subcultures have begun to appropriate cell phones for idiosyncratic uses that help to define their niche or social identity. Today’s Forum will examine the cell phone as a technological object and as a cultural form whose uses and meaning are increasingly various, an artifact uniquely of our time that is enacting, to borrow the words of a contemporary novelist, “a ceaseless spectacle of transition.”

The story
Probably no means of communication has revolutionized the daily lives of ordinary people more than the telephone. Simply described, it is a system which converts sound, specifically the human voice, to electrical impulses of various frequencies and then back to a tone that sounds like the original voice. In 1831, Englishman Michael Faraday (1791-1867) proved that vibrations of metal could be converted to electrical impulses. This was the technological basis of the telephone, but no one actually used this system to transmit sound until 1861. In that year, Johann Philip Reis (1834-1874) in Germany is said to have built a simple apparatus that changed sound to electricity and back again to sound. A crude device, it was incapable of transmitting most frequencies, and it was never fully developed.

Service Lines and Switchboards
In 1877, construction of the first regular telephone line from Boston to Somerville, Massachusetts was completed. By the end of 1880, there were 47,900 telephones in the United States. The following year telephone service between Boston and Providence had been established. Service between New York and Chicago started in 1892, and between New York and Boston in 1894. Transcontinental service by overhead wire was not inaugurated until 1915. The first switchboard was set up in Boston in 1877. On January 17, 1882, Leroy Firman received the first patent for a telephone switchboard.

Exchanges and Rotary Dialing
The first regular telephone exchange was established in New Haven in 1878. Early telephones were leased in pairs to subscribers. The subscriber was required to put up his own line to connect with another. In 1889, Almon B. Strowger a Kansas City undertaker, invented a switch that could connect one line to any of 100 lines by using relays and sliders. This switch became known as "The Strowger Switch" and was still in use in some telephone offices well over 100 years later. Almon Strowger was issued a patent on March 11, 1891 for the first automatic telephone exchange.
The first exchange using the Strowger switch was opened in La Porte, Indiana in 1892 and initially subscribers had a button on their telephone to produce the required number of pulses by tapping. An associate of Strowgers' invented the rotary dial in 1896 which replaced the button. In 1943, Philadelphia was the last major area to give up dual service (rotary and button).
