Types of Mobile Phones and Their Features
A cell phone, mobile phone or simply cell, phone, sometimes shortened to just cell, phone or hand phone and sometimes also referred to as mobile phone is a small portable phone that will make and receive calls on a short-range radio frequency signal while the user is travelling within a phone service zone. These phones are not considered a standard phone as they are usually smaller than the size of a typical walkie talkie; however, they are often the only communication device for a family that cannot afford a landline phone. The great thing about having a cell is that you can talk with anyone in the world and even receive and send email at the same time. Many people like using their cell phone while they are travelling because it allows them to keep in constant contact with their loved ones, work colleagues, and friends wherever they are in the world.
There are various types of mobile technology and the one you decide upon depends on your requirements. Some people just need basic features such as receiving and sending text messages, receiving phone calls, playing music and video, enjoying live television, surfing the Internet and checking the news while some others may require added features such as taking pictures, streaming video and playing games. Some mobile devices use GSM technology which is a generic way to describe the technology used in communication devices by the cell phone companies such as CDMA, FLEX, GSM and UMTS. CDMA, or Code Division Multiple Access technology is used to provide mobile phones with the ability to communicate with base stations and other mobile devices that may be equipped with different types of equipment.
Another very popular mobile phone is the VOIP (Voice over Internet Protocol) phone which is capable of making international telephone calls. The advantage of a VOIP call over traditional telephony is that the call can be attended to using a cell phone or regular phone. There is also an application called Skype which enables free video chat which is very useful if you are going to meet a new friend or talk to your business associates on a professional level.
