Fendensen small square Fessenden demonstrates a wireless radio telephone Cellphones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through 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.

Mobilephone small square Zero Generation (0G) of mobile telephones In 1945, the zero generation (0G) of mobile telephones was 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 during calls, which allows the user to move from one cell (the base station coverage area) to another cell, a feature called "handover".

It may look more like a boombox than a portable phone, but this boxy, bulky device was actually Nokia's first mobile (if you can call it that) phone. Introduced in 1982, the Nokia Mobira Senator was designed for use in cars. After all, you wouldn't want to use this phone while walking: It weighed about 21 pounds

In general the frequencies used by 2G systems in Europe were higher though with some overlap, for example the 900 MHz frequency range was used for both 1G and 2G systems in Europe and so such 1G systems were rapidl

But in 1993, it was a novel idea. The Simon Personal Communicator, jointly marketed by IBM and BellSouth, was the first mobile phone to add PDA features. It was a phone, pager, calculator, address book, fax machine, and e-mail device in one package, albeit a 20-ounce package that cost $900

Before the Motorola StarTAC was introduced in 1996, cell phones were more about function than fashion. But this tiny, lightweight phone ushered in the concept that style was just as important, ultimately paving the way for today's sleek-looking phones like the Motorola Razr. This 3.1-ounce clamshell-style phone, which could easily be clipped to a belt, was the smallest and lightest of its time. In fact, it was smaller and lighter than many of today's te

There were many doubters who believed Bluetooth would be a distant memory in just a couple of years. However, multiple years have passed and Bluetooth continues to make strides and advancements everyday.

In the late 1990s, Nokia's candybar-style cell phones were all the rage. Sporting a monochrome display, an external antenna, and a boxy, 5.2-inch tall frame, the Nokia 6160 was the company's best-selling handset of the 1990s. The somewhat sleeker Nokia 8260, introduced in 2000, added a colorful case and lost some of the 6160's bulk: it stood only about 4 inches tall and weighed 3.4 ounces, compared with almost 6 ounces for the 6160.

Developed by the Canadian company Research In Motion (RIM), it delivers information over the wireless data networks of mobile phone service companies. BlackBerry first made headway in the marketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, s

If you're one of the many fans of the Palm OS-based Treo phone, you might want to thank Kyocera. The company's QCP6035 smart phone, which hit the retail market in early 2001 and cost between $400 and $500 (depending on the carrier), was the first Palm-based phone to be widely available to users. It included a measly 8MB of memory, and sported a bland monochrome display, but it paved the way for future products.
3g small square 3G and Standard Standaridization Not long after the introduction of 2G networks, projects began to develop third generation (3G) systems. Inevitably there were many different standards with different contenders pushing their own technologies. Quite differently from 2G systems, however, the meaning of 3G has been standardized in the IMT-2000 standardization processing. This process did not standardize on a technology, but rather on a set of requirements (2 Mbit/s maximum data rate indoors, 384 kbit/s outdoors, for example). At t

Back when Palm and Handspring were still rivals, Handspring made waves with the Treo 180. More PDA than phone, the Treo 180 came in two versions: one with a QWERTY keyboard for typing (pictured), and another (the Treo 180g) that used Graffiti text input instead. Like the Kyocera QCP6035, it featured a monochrome screen, but boasted 16MB of memory.

Before the T-Mobile Sidekick became Hollywood's "it" phone, it was known as the Danger Hiptop. PC World liked it so much that we named it our product of the year in 2003. While its voice capabilities were only mediocre, this was one of the first devices to offer truly functional mobile Web browsing, e-mail access, and instant messaging. Plus, it pioneered that nifty swiveling design.

Today, most cell phones come with a built-in camera. But, just a few years ago, a camera phone was hard to come by. In 2002, Sanyo and Sprint debuted the Sanyo SCP-5300 PCS phone, which they claimed was the first mobile phone available in America with a built-in camera. (A camera phone from Sharp had been available in Japan for a few years.) At its highest resolution, it captured VGA (640 by 480) images--a far cry from today's 5-megapixel camera phones like the N
Recycing act small square Cell Phone Recycling Act In late September, California Gov. Arnold Schwarzenegger signed the Cell Phone Recycling Act of 2004 (Assembly Bill 2901), which requires cell phone sellers to take back and recycle old phones at no cost to consumers, beginning on July 1, 2006. California is the first state to impose such a requirement, says Mark Murray, executive director of Californians Against Waste, an environmental group headquartered in Sacramento, Calif. Each day, Californians cast aside about 25,000 cell phones, of whi
Music cell small square The Music Cell Phone It promised to bring together the best of two worlds: Apple's excellent iTunes music player and Motorola's cell phone design expertise. The Motorola Rokr, released in September 2005, was the first music phone to incorporate Apple's music software. It allowed users to transfer songs purchased from iTunes to the phone for listening on the go. Unfortunately, users found song transfers to be painfully slow, and many were stymied by the 100-song limit imposed on their music collections. Still, this h

About two thirds of these are on the WCDMA standard and one third on the EV-DO standard. The 3G telecoms services generated over 120 Billion dollars of revenues during 2007 and at many markets the majority of new phones activated were 3G phones. In Japan and South Korea the market no longer supplies phones of the second generation. Earlier in the decade there were doubts about whether 3G
