Cellular Phone

Simple to use and with more and more functions, the cell phones are a concentrate of technology and a status symbol. This guide will discuss the various aspects of the cell phone, trying to focus on the technical characteristics and differences between brands and models.

History

Although already in 1973 someone managed to make his first phone call from a mobile phone (just for not naming names, a certain Martin Cooper, an employee of Motorola), in reality the history of this type of phone has become so popular was founded in 1983, when Motorola, tired of making only prototypes, decided to introduce one, though certainly not a figure to everyone (over $ 3000!). Gradually, the technology has moved on cell phones have evolved accordingly, that is why there have been several generations of mobile phones (technically called a number followed by a G) :

* 0G [1945] The previous generation to real mobile phones, which are technically called ‘radiotelephone’, as employing simple radio waves.
* 1G [1983] (analog) .The first generation, that of the first boom of mobile phones, which include, among others, the TACS
* 2G (digital) – GSM and others.
* 3G (digital broadband) – UMTS and the like.
* 4G (multiplexing and others).

Today the prices of cell phones vary greatly depending on the features and brand, ranging from a minimum of 50-60 euro to a maximum of over 500 euros (for mobile integrated into PDAs. Found that many telephone operators, especially the UMTS, the phone also currently offer free or nearly so, after signing a contract that commits the buyer to pay a certain sum each month.

Types of cell phones

Going down there on the market for the specific types of phones, from the old TACS (Total Access Communication System), now outdated analog technology, existing GSM, up to all new UMTS. In this section we will try to guide and understand more particularly the GSM (Global System for Mobile communication, ie Global System for Mobile communication). This is a protocol created back in 1987 but made standardized in 1989, where today some 2 billion people can speak to one another, it also reveals the most widely used protocols at the time of writing this guide (May 2007): About 70% of phones using this technology.

It can be dual band GSM, triband or quadband. It is simply means that they can transmit and receive frequencies in two classes, three or four, although many may seem just a publicity stunt, in fact, this characteristic becomes crucial in case you want to use the phone outside Italy and each nation operates in fact in a specified range of frequencies, and only if a device supports a given frequency will be able to be used in China than in Canada, rather than the United States. Fortunately there are now only 4 classes of frequency occupied by the GSM network, so we will have at most a quad-band phone, and in particular:

* GSM 900 band The world’s most popular
* GSM 1800 used in some countries
* GSM 1900 used in North America
* GSM 850  used in the United States, Asia and South America

Key Features

In addition to the useful features of the phone and multimedia models today, consider whether you need the following:

* Phone with integrated microphone and loudspeaker, which does not require the use of hands in the car or elsewhere (but avoid using a phone while driving anyway).
* Programmable standby: the latter allows you to create menus quickly on the touch screen of a phone, so you can easily access the features and functions you use most, such as contacts and text messages.
* Headphone jack standard connector, also known as 2.5 or 3.5 mm, is compatible with most headphones. Some phones with proprietary connector may include an adapter for the standard connector.
* Voice Command: This feature allows you to type the numbers from your address book by saying the name, without following the standard procedure. You can also type the numbers by saying the figures.
* Text messages predefined or custom: in addition to providing a comfortable means of communication, messages can be sent to even when networks are overloaded. Most phones have pre-defined messages such as “I’m late” or “call home”. The majority allows you to program personalized messages for emergency or frequent use, for example, “I left Billy football.”
* Bluetooth: This technology allows the phone to work with wireless headsets and most of the headsets in the car for wireless calls. Some phones support Bluetooth headset for music and other multimedia devices. Some people manage to exchange, wireless, photos, contacts and other files with other compatible Bluetooth devices such as computer, mobile phone or PDA.
* Memory card: many mobile phones have slots that accept memory cards to expand the memory capacity of up to 32 gigabytes. These removable cards can also serve as an easy way to transport files from your phone to other devices and vice versa, provided that the manufacturer has placed the slot behind the battery cover. The formats include Secure Digital SD Card, miniSD and MicroSD.
* Satellite navigation: all phones have some kind of location-based technology to help emergency service personnel find you if you enter the 911 or 112. However a growing number of mobile supports GPS navigation services. They integrate GPS with maps and search engines to give you directions in real time, and progressive voice on a given address or to help you find nearby businesses by name or category, such as pizza and hospitals. Some phones do not have the shift automatic, audible directions, and other advanced capabilities, which limit their usefulness while driving.
* QWERTY keyboard: keyboards make the composition and editing of texts and e-mail much easier than a keypad. Some phones have keyboards that are trying to save space having some letters, numbers and symbols on the same text. These keyboards “condensed”, although still cheaper than a keypad, are not easy to handle as the Qwerty keyboard.
* Hearing aid compatibility: Some phones interfere with hearing aids. Even the ones compatible not guarantee to work with all devices. Your doctor can help you choose a phone compatible with the device you use.

Connectivity

Another element that emerges by the difference between a mobile and another is the type of connections. This element should be considered if you want to share photos, music, etc.. with their friends, or if you want to surf the internet with the Internet doorstep. The main connections that exist today are:

* Infrared, to exchange data, now supplanted by the Bluetooth (although still many phones have a connection of the first kind).
* Bluetooth, which is used to exchange pictures, music and files between a phone and another in general or between phone and PC equipped with Bluetooth or other device.
* WiFi to surf the Internet, set up a mini-network of computers or phones, etc..
* Internal modem, if you want to use the phone to surf the internet, perhaps by connecting a computer and viewing the Internet on your PC.

Other relevant characteristics

The quality of a cell is given mainly by the reception, but despite being something fundamental, such a characteristic ‘ethereal’ is often poorly documented (and documentation). Wherever you are, whatever the conditions, a good phone has even better chances to hook the repeater properly. Unfortunately, since there are many studies in this regard, purchasers looking for a good reception to trust the advice of his friend, the expert, or dealer in office, putting into practice a choice more dogmatic than scientific. In any case, dogmatic, in fact, two of the brands with better reception are, according to many, Nokia and Motorola. (Even if also vary from model to model).

Battery life is another strong point of a good cell phone: Even if nowadays most phones have good values, there are significant differences between trademarks and easily traceable in the documentation provided by manufacturers. Unfortunately, like many other things, the tests carried out by producers on their mobile phones are becoming a bit ‘part, so the values given regarding the battery life in standby (ie screen Auto-) and conversation (or talking constantly) are always a little higher effective autonomy. When buying a cell phone you can then take secondary characteristics, such as the amount of memory installed.

This value is important if you want to use the phone even take (or store), many photos, listen to entire CDs in MP3, or simply, in the case of the latest phones, and turn them into satellite navigation systems complete with software and maps. The values vary widely: from 4MB to 41MB and more, there is also the possibility that a cell is fitted with an expansion card (which is quite desirable): this makes it possible to buy a few dollars all the amount of memory that wants, and wanting it can change for any eventuality. In the latter case it is preferable that the expansion is like SD, MMC or CF secondly, because they are the most common in general and thus easily purchased in any store including non-stocked.

As for the mp3 player, not all phones it consists, and this needs to be done sorted and understand what is meant by ‘mp3 player’, and many special sites in the datasheets writes that a cell has the ‘mp3 player’ when he the specific application installed to read the mp3, but other sites when the phones have the ability to add mp3 ringtones, regardless of whether or not the application to play it, and often not clear which of these two statements are related. For me, it is important that you can put in your phone mp3 ringtones, because then you have some sort of customization of the device. If you buy an appliance with only the polyphonic ring tones, I recommend buying one with at least 24 entries. Finally, I will list below a series of acronyms that represent a set of secondary characteristics are not dealt with above but it might be useful:

* EMS and MMS
Evolution of the SMS, the first is used to pass even small children and smileys gif (mobile phones must be compatible), the second is used to pass along with the message also photos, mp3 and other multimedia elements.
* WAP
It is the protocol used to surf the internet with one mobile phone, has a misfortune: the pricing is seconds.
* GPRS
It is the protocol used to browse the internet with one mobile phone, faster than WAP, Opera, packet-switched and tariffs is kb (the more you download, the more you pay).

As the eye wants its part, with the advance of technology also the aesthetic had to deal with the increasingly demanding user. And here is the proliferation of three types of mobile:

* By closing the book (the typical form of ‘clashes’, especially useful for those who put this device in his pocket).
* With close to death (one of the last born, return to it in his pocket but also operate through the basic fundamental keys that are always visible (those calling and hanging up, and sometimes those of navigation in the menu)).
* Without closing (mostly usable car, and all other occasions through the use of the keypad lock).

OS

The modern mobile phones also are increasingly tending to look like electronic diaries handyman, so that at most from simple phones to send text messages over phone calls, we turned to two additional categories of products:

* Mobile handyman that integrate electronic diaries, notepads, file manager, etc..
* PDAs that have the functionality of traditional phones.

The difference between the two types of products is becoming increasingly thin, except for the price, which for the latter is much higher (because it’s true handheld computers), and hence for computing power. In short, the handhelds can be recommended to all those for whom the use of a complete instrument such as a real portable computer has priority over the use of simple mobile handset (professionals, entrepreneurs, etc.).. For these purposes ‘emerging’ mobile phones, more and more brands that decide to install software such as real operating systems that make it possible to provide a standardized platform on which to run other software configurations that can be downloaded from Internet (or, if not as ‘geeks’, program directly). Just to give you an example, the Nokia 6600 mounts a Symbian operating system S60. With the operating system, if you want to run games or do you use light applications for mobile phones, it is essential that these devices have a Java J2ME. If you are interested in handheld, we recommend our guide to the handheld.

How to choose cell phones

* Search the important characteristics
The cameras and music players are fun, but other features such as programmable standby, speakerphone and voice command could be more crucial for an easier option.
* Consider the shape and size
Phones that fold, slide or spin are typically more compact when closed. Phones that have the shape of a finger can be used without first being opened. The best choice depends largely on personal preference, then go visit a store and pick up a phone if possible. Make sure you’re able to easily use most of the buttons with one hand. Make a test call and access the menu. There are also buttons small, with strange shapes or unusual reasons, not suitable if you’re trying to do a number with little light.
* Check the display
Most color screens are good with low light and normal, but some are difficult to see in bright sunlight or a bright light. Try the phone outside or under a bright light. Phones in which the input and output numbers are large and black against a white background are easiest to read in most conditions. Ensure that indicators like battery life and signal strength are clearly visible.
* Check prices and special promotions
Discounts and special offers can be substantial, but change frequently. To make a bargain, check out the offers online and in retail stores phone companies and then see what offer the independent dealers on their site and in their stores. If possible buy a new phone when switching telephone operator + or signing a new contract of service with your existing operator. Generally do a better deal when you sign a contract as a highly discounted price or even a cell phone for free.
* Consider buying online

Manufacturers

* Nokia
The history of Nokia starting from far away, ie as Fredrik Idestam in 1865, is a company for paper production, the first modern means for supporting non-verbal communication. Over a century later he will rise to the first signs for the development of the multinational, and this will happen in 1981 with the launch of the service Nordic Mobile Telephone (NMT), limited at first only to the countries of the North. The following year Nokia will create the first mobile phone, a telephone installed in cars. Since then I have spent several years and Nokia has become one of the largest companies in the field of mobile telephony, whose products, innovative, good value for money, meet the needs of many customers worldwide.
* Motorola
Motorola started its activities at the beginning of the twentieth century, thanks to the founding of the Galvin Manufacturing Corporation in Chicago, this company, which derives from the current Motorola, is engaged in the production of batteries and radio. The first steps into the world of telephony will be paths in the seventies, when the company became “Motorola” in 1947, will be the first prototype of a portable radio telephone that uses DynaTAC, this episode will set the foundation for the current success This multinational arrived in Italy in 1966. Mobile phones currently produced by this company are valuable features that allow you to combine aesthetics with functionality and ease of use.
* Sony Ericsson
Sony Ericsson was born in October of 2001 through the merger between Sony Corporation and Telefonaktiebolaget LM Ericsson, the union took place with a breakdown in the middle of the activities of the previous two companies, was formed with the goal of creating a society still stronger and more powerful in the field of technology, even in terms of the constitution of mobile phones. The company not only offers valuable mobile phones, many different models, but also services that allow it to further increase the prestige and trust of customers.
* NEC
The company NEC was born in 1899, its initial activities was the manufacture and import of materials and resources useful for communication. In 1942, the camp’s activities expanded to cover up even the radio, diversifying, as the production technology. In recent years the production performed by the NEC has also seen the collaboration of Siemens in order to further improve the proposed technologies to the public. The models of mobile phones made by NEC are many, each has distinct characteristics that are well adapted to individual market demands.
* LG
LG Electronics Inc was born in Korea in 1958 is already original sound production activities of domestic appliances and high-tech devices. Over time, the catalog company has expanded while including many modern products and affordable for much of the population, products now covered by the historic mark of the “smiling face” LG. Mobile phones made by this company are of different types, either GSM or UMTS, and combine the proper functioning of the beauty and the design outward.
