HISTORY OF MOBILE COMPUTING

Since the 1990s, the idea of mobile computing has been around. Mobile computing has evolved from two-ways radios that use large antennas to communicate simple messages to three inch personal computers that can do almost everything a regular computer does. People can’t go to their local McDonalds and not see a laptop linked up to a hotspot Static network. This actually used to mean radio transmitters that operated on a stable base, which is usually done with the help of large antennas. Two way radios used by police officers were also considered mobile technology but now, it means people can connect wirelessly to the internet or to a private network almost anywhere. As long as a person has one of the devices capable of wirelessly accessing the internet, they are also participating in mobile computing.

Nowadays, pocket PCs are other ways to access the internet conveniently on the earth devices that have being developed for mobile computing which has taken over the wireless industry. The new communication is very a powerful tool for both personal and business use. The portable computer changed the computing world confiered to hundred years back from huge machines that could not do much than word processing to small hand held devices.

The idea of cellular phones was conceived by researchers in AT & T Bell Labs in 1947 when Wireless network started. They requested for allocation of a widespread large number of radio spectrum frequency to make mobile phone services attainable. The first wireless network was authorized in Germany in 1957 and was called A-Netz and it used analog technology at 160MHz which was wireless but not a cellular network.

Outgoing calls was the only calls made possible by then, later on receiving incoming calls became possible as long as the location of the mobile station was known.

Martin Cooper invented the first mobile phone handset in April 1973, a preliminary model of public cellular network was created in 1977 by AT &T and Bell Labs.

Finally FCC authorized the commercial cellular service for the USA in 1982 and in 1983, the first American commercial analog cellular service AMPS (Advanced Mobile Phone Service) was made commercially available in Chicago.
