GOOGLE PHONE


Google phone to cost $179, debut Oct. 22
Android packs a large touch screen, trackball, and a slide-out keyboard

Mark Lennihan / AP
NEW YORK - The first phone that harnesses Google Inc.'s ambition to make the Internet easy to use on the go was revealed Tuesday, and it looks a lot like an iPhone.

T-Mobile USA showed off the G1, a phone that, like Apple Inc.'s iPhone, has a large touch screen. But it also packs a trackball, a slide-out keyboard and easy access to Google's e-mail and mapping programs.

T-Mobile said it will begin selling the G1 for $179 with a two-year contract. The device hits U.S. stores Oct. 22 and heads to Britain in November and other European countries early next year.

The phone will be sold in T-Mobile stores only in the U.S. cities where the company has rolled out its faster, third-generation wireless data network. By launch, that will be 21 cities, including New York, Los Angeles, Houston and Miami.

In other areas, people will be able to buy the phone from T-Mobile's Web site. The phone does work on T-Mobile's slower data network, but it's optimized for the faster networks. It can also connect at Wi-Fi hotspots.

The data plan for the phone will cost $25 per month on top of the calling service, at the low end of the range for data plans at U.S. wireless carriers. And at $179, the G1 is $20 less than the least expensive iPhone in the U.S.

Android, the free software powering the G1, is a crucial building block in Google's efforts to make its search engine and other services as accessible on cell phones as they already are on personal computers. The company believes it eventually might make more money selling ads that get shown on mobile devices than on PCs, a channel that will generate about $20 billion in revenue this year.

Both Yahoo Inc. and Microsoft Corp. also are investing heavily in the mobile market in hopes of preventing Google from extending the dominance it enjoys in searches initiated on PCs.

In an interview, Google co-founder Sergey Brin said Google's aims are broader than mobile advertising.

"Generally, we think if there are great (operating systems) out there that let people have great devices and great applications, people use the Internet on their phones much more," Brin said at the launch event in New York. "And whenever people use the Internet more, they end up using our services, and ultimately, that's good for our business. There's no secret plan to have ads pop up or anything."

Like the iPhone, the G1 has a high-resolution screen, making it easier to browse Web sites that haven't been specifically adapted for a cell phone. Unlike the iPhone, Research in Motion Ltd.'s BlackBerrys and most other high-end smart phones sold in the U.S., the G1 has a very limited ability to connect to corporate e-mail servers. That means the device's initial market is likely to be consumers.

On the face of it, the G1 doesn't do much that other high-end phones don't already do. But Google is counting the device unleashing the creativity of software developers, who are free to write applications for it.

"There aren't a lot of `wow' features on it. I think what we can expect from it is that it's going to be a good Internet phone," said Lance Ulanoff, editor-in-chief of PC Magazine.

Developers will be able to submit applications to an online store run by Google, which will apply minimal vetting.

"The key is going to be what app developers are going to do for it," said Ross Rubin, an analyst with NPD Group. "They didn't have a lot to show today."

Apple launched a similar store for the iPhone this year, but keeps much tighter control over what applications are available. It has blocked programs that compete with its own.

The G1 won't connect to Apple's iTunes store, but one of the initial applications will be a music store from Amazon.com Inc., which will let users download songs directly to the phone. In an unusual move for a mobile-phone music store, the songs will have no copy protection.

Brin himself has written an application for the phone.

"It's just very exciting for me as a computer geek to be able to have a phone that I can play with and modify and innovate upon just like I have with computers in the past," he said.

You carry your phone almost everywhere, so it's important that you find the model that's right for you and one that works with your carrier. Fortunately, CNET is here to help. We've chosen five handsets that we think are the best cell phones right now in any category. If you'd like to drill deeper, follow the links at the left for our favorite cell phones in several categories. These lists change frequently, so check back often.


Apple iPhone 3G
Just over a year after Apple birthed the first iPhone, the long-awaited, next-generation iPhone 3G has arrived bearing a mildly tweaked design and a load of new features. With access to a faster 3G wireless network, Microsoft exchange server e-mail, and support for a staggering array of third-party software from the iPhone Apps store, the new handset is the iPhone we've been waiting for. It still lacks some basic features but when compared with what the original model was year ago, this device sets a new benchmark for the cell phone world.

RIM BlackBerry Curve 8320
T-Mobile's Curve has the same sleek design as the original Curve, but it offers a more spacious and easy-to-use keyboard. You also get a 2-megapixel camera, which will endear the 8320 to a wider audience, and we're thinking it'll be a hit. The Curve offers solid performance, a great design, excellent messaging features, and the addition of Wi-Fi is icing on the cake.

Nokia N95
When it comes to cool Nokia phones, the United States often is left out in the cold while our friends in Europe and Asia get all the goods. Well, it seems Nokia has heard our cries; the company has started selling more of its best handsets in North America. One model in particular has attracted a lot of attention, and that would be the Nokia N95. The demand for this smartphone has been so great that Nokia decided to release a North American Edition of the Nokia N95. For the most part, it's very similar to the original version, but there are some major additions that make it a better buy, namely 3G support, more memory, longer battery life, and faster performance.

Price: $444.99 - $450.00 (check prices)

Samsung Instinct
Though the Instinct and the iPhone look about the same, there are some important feature distinctions. The Instinct offers its own brand of visual voice mail and it bests the first incarnation of the iPhone by offering 3G network compatibility, integrated GPS, and work e-mail support, just to name a few. The new iPhone 3G will be more evenly matched, but even the Instinct gets points for its multimedia messaging, voice dialing and video recording. In the important areas of usability and performance, however, the Instinct struggled on a few fronts. The Web browser wasn't quite as easy to use as we had hoped, the camera lacked editing features, and the Instinct's call and video quality were variable. However, even with those caveats, the Instinct remains a powerful, innovative cell phone with a loaded feature set and an appealing design.

Price: $129.99 - $599.99 (check prices)

Sony Ericsson W760i
The Sony Ericsson didn't let us down in the slightest. It first captured our eye at CES 2008 where it was a finalist in the cell phones category for CNET's Best of CES. At the time, we admired its slick design and its laden feature set, which includes a motion sensor, an accelerometer, and support for three UMTS/HSDPA bands. And now, seven months later, we can report that this super world phone offers so much to like that it earned our Editors' Choice Award. If you want a Walkman phone you can't do better.

HISTORY OF MOBILE PHONES



In 1908, U.S. Patent 887,357 for a wireless telephone was issued in to Nathan B. Stubblefield of Murray, Kentucky. He applied this patent to "cave radio" telephones and not directly to cellular telephony as the term is currently understood.[48] Cells for mobile phone base stations were invented in 1947 by Bell Labs engineers at AT&T and further developed by Bell Labs during the 1960s. Radiophones 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 1973. 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.[citation needed]

In 1945, the zero generation (0G) of mobile telephones was introduced. 0G mobile phones, such as Mobile Telephone Service, were not cellular, and so did not feature "handover" from one base station to the next and reuse of radio frequency channels.[citation needed] Like other technologies of the time, it involved a single, powerful base station covering a wide area, and each telephone would effectively monopolize a channel over that whole area while in use. The concepts of frequency reuse and handoff as well as a number of other concepts that formed the basis of modern cell phone technology are first described in U.S. Patent 4,152,647 , issued May 1, 1979 to Charles A. Gladden and Martin H. Parelman, both of Las Vegas, Nevada and assigned by them to the United States Government.

This is the first embodiment of all the concepts that formed the basis of the next major step in mobile telephony, the Analog cellular telephone. Concepts covered in this patent (cited in at least 34 other patents) also were later extended to several satellite communication systems. Later updating of the cellular system to a digital system credits this patent.

Martin Cooper, a Motorola researcher and executive is widely considered to be the inventor of the first practical mobile phone for handheld use in a non-vehicle setting. Using a modern, if somewhat heavy portable handset, Cooper made the first call on a handheld mobile phone on April 3, 1973.[49]

The first commercial citywide cellular network was launched in Japan by NTT in 1979. Fully automatic cellular networks were first introduced in the early to mid 1980s (the 1G generation). The Nordic Mobile Telephone (NMT) system went online in Denmark, Finland, Norway and Sweden in 1981.[50] NMT was the first mobile phone system that enabled international use of the phone, or "roaming" on other networks in other countries. This was followed by a boom in mobile phone usage, particularly in Northern Europe.[citation needed]

In 1983, Motorola DynaTAC was the first approved mobile phone by FCC in the United States. In 1984, Bell Labs developed modern commercial cellular technology (based, to a large extent, on the Gladden, Parelman Patent), which employed multiple, centrally-controlled base stations (cell sites), each providing service to a small area (a cell). The cell sites would be set up such that cells partially overlapped. In a cellular system, a signal between a base station (cell site) and a terminal (phone) only need be strong enough to reach between the two, so the same channel can be used simultaneously for separate conversations in different cells.

Cellular systems required several leaps of technology, including handover, which allowed a conversation to continue as a mobile phone traveled from cell to cell. This system included variable transmission power in both the base stations and the telephones (controlled by the base stations), which allowed range and cell size to vary. As the system expanded and neared capacity, the ability to reduce transmission power allowed new cells to be added, resulting in more, smaller cells and thus more capacity. The evidence of this growth can still be seen in the many older, tall cell site towers with no antennae on the upper parts of their towers. These sites originally created large cells, and so had their antennae mounted atop high towers; the towers were designed so that as the system expanded—and cell sizes shrank—the antennae could be lowered on their original masts to reduce range.

The first "modern" network technology on digital 2G (second generation) cellular technology was launched by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard which also marked the introduction of competition in mobile telecoms when Radiolinja challenged incumbent Telecom Finland (now part of TeliaSonera) who ran a 1G NMT network.

The first data services appeared on mobile phones starting with person-to-person SMS text messaging in Finland in 1993. First trial payments using a mobile phone to pay for a Coca Cola vending machine were set in Finland in 1998. The first commercial payments were mobile parking trialled in Sweden but first commercially launched in Norway in 1999. The first commercial payment system to mimick banks and credit cards was launched in the Philippines in 1999 simultaneously by mobile operators Globe and Smart. The first content sold to mobile phones was the ringing tone, first launched in 1998 in Finland. The first full internet service on mobile phones was i-Mode introduced by NTT DoCoMo in Japan in 1999.

In 2001 the first commercial launch of 3G (Third Generation) was again in Japan by NTT DoCoMo on the WCDMA standard.[citation needed][51]

Until the early 1990s, most mobile phones were too large to be carried in a jacket pocket, so they were typically installed in vehicles as car phones. With the miniaturization of digital components and the development of more sophisticated batteries, mobile phones have become smaller and lighter.

In the 2000s, video and TV services are driving forward third generation (3G) deployment. In the future, low cost, high speed data may drive forward the fourth generation (4G) as short-range communication emerges. Service and application ubiquity, low cost data delivery, and a high degree of personalization and synchronization between various user appliances will be drivers. At the same time, the radio access network may evolve from a centralized architecture to a distributed one.[Wikipedia]

HANDSETS


Handsets
Nokia is currently the world's largest manufacturer of mobile phones, with a global device market share of approximately 40% in 2008. Other major mobile phone manufacturers (in order of market share) include Samsung (14%), Motorola (14%), Sony Ericsson (9%) and LG (7%).[4] These manufacturers account for over 80% of all mobile phones sold and produce phones for sale in most countries.

Other manufacturers include Apple Inc., Audiovox (now UTStarcom), Benefon, BenQ-Siemens, CECT, High Tech Computer Corporation (HTC), Fujitsu, Kyocera, Mitsubishi Electric, NEC, Neonode, Panasonic (Matsushita Electric), Pantech Curitel, Philips, Research In Motion, Sagem, Sanyo, Sharp, Siemens, Sendo, Sierra Wireless, SK Teletech, Sonim Technologies, T&A Alcatel, Huawei, Trium and Toshiba. There are also specialist communication systems related to (but distinct from) mobile phones.

There are several categories of mobile phones, from basic phones to feature phones such as musicphones and cameraphones, to smartphones. The first smartphone was the Nokia 9000 Communicator in 1996 which incorporated PDA functionality to the basic mobile phone at the time. As miniaturization and increased processing power of microchips has enabled ever more features to be added to phones, the concept of the smartphone has evolved, and what was a high-end smartphone five years ago, is a standard phone today. Several phone series have been introduced to address a given market segment, such as the RIM Blackberry focusing on enterprise/corporate customer email needs; the SonyEricsson Walkman series of musicphones and Cybershot series of cameraphones; the Nokia N-Series of multimedia phones; and the Apple iPhone which provides full-featured web access and multimedia capabilities.

MY PHONE


The mobile phone (also called a wireless phone or cellular phone)[1] is a short-range, portable electronic device used for mobile voice or data communication over a network of specialized base stations known as cell sites. In addition to the standard voice function of a telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, bluetooth, infrared, camera with video recorder 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 is satellite phones).
