The mobile phone, also known as cellular phone, has become one of the most successful inventions in the 20th century. In the late 90s, mobile phone technology,mobile phone history mobile phones became one of the major communication devices. The first commercial mobile phone system started in 1979 in Japan. According to Cellular Online, the global mobile phone subscribers in 2003 are around 1.52 billion, which is about 20 percent of the current world population. This figure showed the success of the mobile phone industries. In about 20 years' time, this technology conquered the global and became a demand for the majority of people in the world. It provided communication for people no matter anywhere and anytime.
Along with the development of mobile phones, many subsidiary technology developed by the mobile phone companies were also developed and influencing other products such as Bluetooth, Symbian (an operating system (OS) specially designed for mobile phones) and some software companies that designs software for the Symbian OS. These technologies improved the interactive among mobile phones and the users. It provided a much convenience and wider usage for the mobile phone users. More and more companies now are trying to gain a share in the mobile phone market. Many big companies which are developing PDA OS such as Window CE (Pocket PC), PALM and Linux are also engaging their OS with mobile phones functions. This proved that the mobile phone industry is indeed a good market to invest in. The competition in the market is also another reason causing the mobile phone industry to develop in such a short time.
Digital wireless and cellular roots go back to the 1940s when commercial mobile telephony began. Compared with the furious pace of development today, it may seem odd that mobile wireless hasn't progressed further in the last 60 years. Where's my real time video watch phone? There were many reasons for this delay but the most important ones were technology, cautiousness, and federal regulation.

As the loading coil and vacuum tube made possible the early telephone network, the wireless revolution began only after low cost microprocessors and digital switching became available. The Bell System, producers of the finest landline telephone system in the world, moved hesitatingly and at times with disinterest toward wireless. Anything AT&T produced had to work reliably with the rest of their network and it had to make economic sense, something not possible for them with the few customers permitted by the limited frequencies available at the time. Frequency availability was in turn controlled by the Federal Communications Commission, whose regulations and unresponsiveness constituted the most significant factors hindering radio-telephone development, especially with cellular radio, delaying that technology in America by perhaps 10 years.mobile phone technology,mobile phone history.

In Europe and Japan, though, where governments could regulate their state run telephone companies less, mobile wireless came no sooner, and in most cases later than the United States. Japanese manufacturers, although not first with a working cellular radio, did equip some of the first car mounted mobile telephone services, their technology equal to whatever America was producing. Their products enabled several first commercial cellular telephone systems, starting in Bahrain, Tokyo, Osaka, and Mexico City.mobile phone technology,mobile phone history.
Mobile phone

A mobile telephone or cellular telephone (commonly, "mobile phone" or "cell phone") is a long-range, portable electronic device used for mobile communiction. In addition to the standard voice function of a telephone, current mobile phones can support many additional services such as SMS for text mesasaging, email, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception are satellite phones).
History

The introduction of hexagonal cells for mobile phone base stations, invented in 1947 by Bell Labs engineers at AT&T, was further developed by Bell Labs during the 1960s. Radiophones have a long and varied history going back to the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held cellular radio devices have been available since 1983. Due to their low establishment costs and rapid deployment, mobile phone networks have since spread rapidly throughout the world, outstripping the growth of fixed telephony.mobile phone technology,mobile phone history.
In 1945, the 0G generation of mobile telephones were introduced. 0G mobile telephones, such as Mobile Telephone Service, were not officially categorized as mobile phones, since they did not support the automatic change of channel frequency in the middle of a call, when the user moved from one cell (base station coverage area) to another cell, a feature called "handover".mobile phone technology,mobile phone history.
