Main Features of a Cell phone

Cell phones have become the world’s most popular communication and electronic devices. Some countries even have more cell phones than their population. There are numerous companies out there that manufacture different types and models of cell phones, but basically, all cell phones or mobile phones have common features. All mobile phones have the following basic components:

• A battery, which provides the power to run all of the cell phone’s functions.
• An input system, such as the keypad, touch screen, microphones. These input mechanisms allow interaction between the user and the phone.
• Basic services of the mobile phone in order to allow the user to make phone calls or send text messages.
• Individual GSM, iDEN, WCDA and some satellite phones are identified uniquely by an International Mobile Equipment Identity (IMEI) number.
• All phones of GSM use a SIM card so that accounts can be changed among devices.

Normal mobile phones that offer just the basic telephony and maybe other simple functions like taking photos, playing games and music, are referred to as feature phones. Handsets that have a more advanced ability of computing through the use of software applications are known as smartphones. The first smartphone only added PDA functionality to the basic functions of the mobile phones. The increased processing power of microchips and miniaturization has enabled more features to be added to smartphones. As a result, the smartphone concept has evolved and what was a smartphone three years ago might be a regular phone today.

Cell phone manufacturers have introduced different series of phones in order to capture a specific segment of the market, such as the corporate world, teenagers and various other groups. Some cellular networks also offer free phones on condition that a user will join their network. There are other numerous features that you may find on a cell phone. They include music and video playback, GPS navigation system, RDS radio receiver, memo recoding, alarms, video calling, video streaming, video download, email, internet browsing, ring tone, games, USB, support dual lines, Bluetooth, instant messaging, infrared and many other features.

Some phones even have the capability of making payments through direct schemes of mobile billing or via contactless payments. Some mobile phones also have a feature called an electromechanical transducer, which is normally on the back of the phone and helps the user to hear phone call conversations clearly in a noisy area. It does this by changing electrical voice signals to mechanical vibrations, which then flow through the forehead or cheekbones.
