We have heard of cellphones as well as watches. But a combination of both a watch and a cellphone-not much. The best feature of this mobile cellphone is that it can flip its lid. This provides additional attractive features such as lesser size, greater compatibility and so on. When you just pop it open you get to reveal a fully funtional multimedia mobile phone inside. Under the hood of the U200i mobile phone wristwatch dwells a quad-band (unlocked) GSM phone, complete with a 1.3MP digital camera, Bluetooth connectivity, and full media player capabilities. Other than the time,we can also check out other essential features such as signal strength and battery meter at a glance from the external OLED display. You can even watch tiny little MP4 videos on the 1.5-inch color display, which also happens to offer touchscreen capabilities. In addition to the stainless steel case shown in these pictures, the U200i comes in a solid black case design as well. But the best part of the design has to be the decidedly retro round dial pad, complete with otherworldly blue backlighting.
Future mobile: Morph concept phone from Nokia
The future mobile of Nokia uses Nanotechnology and this device is flexible and streacheble. The Fibril proteins are woven into a three dimensional mesh and that reinforces thin elastic structures. this makes the devices flexible and streachable.This have many magical functions which had never seen before. This is the result of joint research by Nokia and Cambridge Nanoscience Centre (United Kingdom).
Nanotechnology gives magical functions such as flexibility, transparent electronics, and surfaces that clean by themselves. The mobile fits easily in pocket. The eco friendly device is made with biodegradable materials.It charges by absorbing solar energy, smaller long lasting batteries. The Built in sensors to know the environment and air pollution etc. Nano technology enables the device self-cleaning and self-preserving.
Mobile phones come in a variety of different physical styles or form factors that define the design and shape of the device and the arrangement of the various elements on it. Manufacturers are continuously striving to make mobile phones thinner and lighter and to come up with innovative designs. Different form factors for cell phones affect the size (and therefore the portability), functionality, ergonomics and usability of these devices. Users may prefer one form factor over the other based on their specific preferences and requirements.Though there are many form fac tors available in the market, most mobile handsets can be classified under the following broad categories:
Bar
Also referred to as “candy bar,” this is the most basic of handset form factors. Like a bar of chocolate, the phone is rectangular in shape, and does not have any hinges or moving parts. You’ll find a display screen and the standard set of number keys. Depending upon the specific phone model, you may also find soft keys, ‘answer’ and ‘end’ buttons, and navigation keys. The screen and all these keys are placed on the front of the device. Since the keys are exposed, most phones using this form factor also provide a key- guard feature that prevents the keys from being pressed accidentally when it’s in your pocket.
Clamshell
Also referred to as folder, a clamshell phone consists of two halves joined by a hinge. The upper half usually sports the screen and the speaker, while the keys are placed on the lower half. The phone is shut when not in use, hiding the screen and buttons. Most clamshell phones also boast if dual LCD screens: apart from the main screen on the inside, there is also a secondary, smaller screen on the outside that displays information
such as the time, battery status, caller information etc. Depending upon the model, the two screens can have different screen resolutions and colour capabilities. Most phone models using this form factor have also an ‘Active flip’ feature, which means that calls can be answered and ended by opening and closing the phone. In most cases, the size of a clamshell phone is quite com pact when closed as compared to candy bar phones.
Flip
A flip phone is across between the bar and clamshell. Here, most components including the screen and the keys are placed on bottom half of the phone. The top half is usually a plastic flap that folds on top. Again, depending upon the phone model the top half may contain a speaker and even a transparent that enables the user to see a portion of the screen phone is closed. The visible part of the screen display the time and caller ID information. Most flip phones also have active flip feature.
Slider
A relatively newer entrant, phones using a slider form factor are designed much like clamshell phones. The phone has two parts one with the screen and speakers along with some keys, and the other half containing the main keypad. However, instead of folding, the bottom half with the keypad slides out from under the top half. This kind of design also allows the phone to be quite small. Also, in most cases, you can perform certain operations such as answering and ending calls and accessing the phone book and call history without opening the slider.
A handset might seem to be just a device tnat lets you zaiK on a cellular network, but actually, there is a lot you need to know about handsets before you go out and buy one. What do you need? What kind of form factors are available? What about the battery? Then, there’s the camera to be considered. Also, if a mobile phone is to be really mobile, you need to consider connectivity options. Then there are accessories to jazz up your phone -We round off this chapter with descriptions of a few especially desirable phones.
Display Types
Not only do mobile phone displays show caller information, menu options, contacts, etc., mobile phone displays these days need to be capable of displaying thousands of colours so that high-end features such as images and video playback offer the desired user experience. The followingis a brief on the various types of display technologies in use for mobile phones.
LCDS
LCD displays utilise two sheets of polarising material with a liquid crystal solution between them. Crystals in this suspension are naturally aligned parallel with one another, allowing light to pass through the panel. When electric current is applied, the crystals change orientation and block light instead of allowing it to pass through, turning the crystal region dark.There are two main types of Liquid Crystal Displays: STN and TFT.
STN
Super Twisted Nematic LCDs use the passive matrix screen technology, which has no active or controlling element inside the display cell. Pixels are controlled by energising the appropriate row and column drive lines of the matrix from outside the display, resulting in a slow frame rate. STN screens have limited colour range and viewing angles (~15 degrees max).
TFT
With Thin Film Transistor (TFT) LCDs, each pixel is controlled by one to four transistors. Typically one transistor is used for each of the RGB colour channels. Because of this direct control technique, TFT screens are also called Active-Matrix LCDs.TFT technology provides more accurate colour control, allowing it to display more colours and also offer a wider viewing angle range than other types of LCDs.
OLED
OLED stands for Organic Light Emitting Diode. OLED is a flat-panel display technology that is now being used in a variety of devices. Apart from mobile phones, you can also find OLED screens on portable audio players, car audio systems, PDAs and digital cameras. The basic property of OLEDs was discovered in 1985, over a decade before the first displays were seen. Ching Tang, a Kodak researcher, noticed that an organic material glows green if you pass an electrical current through it.An OLED is made by placing a series of organic thin films between two conductors. They operate on the attraction between positively and negatively charged particles. When voltage is applied, one layer becomes negatively charged relative to another transparent layer. As energy passes from the negatively charged layer to the other layer, it stimulates organic material between the two, which emits light visible through a layer of glass. There must be blue, red, and green light-producing organic material to produce the different colours. Because screens using OLED technology produce light themselves, they do not require a backlight as compared to LCD screens. This means that OLED displays require less power and also can be made very thin. Without any other source of illumination, OLED screens can display bright images that are viewable from almost any angle.Like LCDs, OLEDs also come in passive-matrix and active-matrix flavours.Passive-matrix OLEDs are made up of a matrix of electrically-conducting rows and columns making pixels. Between the rows and the columns are the organic layers. On the other side is the substrate, the material which gives the electricity. The more cur-rent applied, the brighter the display.In Active-matrix OLEDs, there is a TFT back plate instead of rows and columns. This controls the brightness of each pixel. There are two TFT arrays per pixel: one to start and stop the charging of the capacitor, and one to provide a constant electrical current to the pixel. Active-matrix OLEDs consume much lower power than passive-matrix ones.OLEDs have the following advantages over LCD or plasma displays: New-age displays: OLEDs can bring in new types of displays, like ultra-thin, flexible or transparent displays.
Power efficiency:
Since OLED screens do not require a back-i hey require much less power compared to other types of displays. This makes OLED a far better
choice for portable devices.
The Dream
In technology circles, it has long been known that CDMA beats the pants off GSM. It is, to state it in no uncertain terms, the technology of the future. Even third-generation GSM networks will use CDMA-based technologies.
Why?
Because CDMA is faster.
Because CDMA is more secure.
Because connections on a CDMA network will never gel
dropped when moving from cell to cell.
Because CDMA base-stations cover a larger area.
The Reality
GSM was the world’s hero, really. It replaced the archaic analogue systems, and its popularity grew fast. While CDMA was commercially available in the US only a couple of years after GSM, this wasn’t so for the rest of the world. The purpose of publishing the GSM standard was to have a world standard for mobile communications, so that all mobile users could roam free across the world without needing to bother about changing handsets. The CDMA standard, however, is patented, and anyone implementing a CDMA network or manufacturing a CDMA handset has to pay a royalty to Qualcomm. Telecom companies the world over, therefore, preferred GSM.
Today, the cellular-using world has 1 billion GSM subscribers to CDMA’s 270 million. Using a GSM phone meant that you were more likely to avail of international roaming. CDMA isn’t being adopted by countries as quickly as one would hope, but where it has been adopted, it’s grown phenomenally. The Indian scenario is quite the same. When mobile telephony came to India, GSM was our only choice. CDMA came in only in the beginning of 2003, but has seen huge growth since then. Nonetheless, GSM still remains the preferred network for most of India’s subscribers.
With both GSM and CDMA moving towards better technologies based on the CDMA technique, one hopes that in the future they would become cross-compatible. This would finally concretise the dream of a fully-connected mobile world. For now, GSM is the Goliath to CDMA’s David. We’re all just waiting for that stone to knock it over.
