A phone, landline phone or cell phone, sometimes shortened to just phone or cell, is a small portable phone that will make and receive calls on a radio signal network while the user is traveling within a phone service area. Some phones are considered global phones which work with networks in other countries while others work more like traditional home phones. The traditional landline or cell phone has the features of a standard telephone as well as some additional capabilities such as voice mail, caller ID, and some even have video calling capabilities. These types of phones come with many different options depending on the price, carrier and features.
There are three main components to a typical cell phones or landline phone system. The three components are communication systems the transmission of signals and information, circuits which handle communications, and key systems which allow the system to recognize call events. Communication systems used in cell phones work through what are called base stations. The range from which a base station can communicate with a cell phone can vary greatly depending on the type of base station used. Base stations usually use a dedicated radio frequency connection to transmit their signals and use antenna arrays or satellites to receive their signals.
On the other hand, there are phones that run on wireless networking technologies such as Wi-Fi and Bluetooth. Some newer phones use a hybrid data plan which enables them to use data services provided by various online vendors such as Google, Yahoo, eBay, Amazon and so forth. The most popular example of this type of phone plan is the Google smartphone. The third component is the hardware which allows phones to connect to the network and also act as a backup for the network in case of a major catastrophe such as a power failure.
There are two primary types of cellular coverage and they are CDMA and GSM. CDMA phones work by receiving a signal and then repeating it back to the carrier. GSM cellular coverage works by using a series of cells linked together using radio waves and transmit the signal in one direction. This is why many people choose GSM cellular coverage for their smartphones. CDMA phones on the other hand use a series of cells linked in a logical pattern and are not able to transmit signals in only one direction.
