The cell phone has become one important item in my daily life. A day without the cell phone may look a century in the wilderness. Gone are the days when a cell phone was a luxurious item in one’s life; today it has become part and parcel of each person’s life. It replaced the wrist watch for time and alarm that wakes one up in the morning; it also replaced the paper calendar on the wall to know the day and date ( Haddon, 2017) . The cell phone has also replaced the bulky diaries for planning daily events were written. In the past putting reminders both at home and in office, colored papers stickers, as well as alarms, were set. The complication with setting a reminder for an activity to be done in the next years or two was almost impossible, but with cell phones, reminders and plans are easily stored for longer.
How the Cell Phone Impacts Life
The cell phone has many uses and has rendered very many other items obsolete. Today the cell phone is primarily used for communication. It provides the user with the ability to communicate with others with great convenience. The cell phone has the ability to convey verbal communication between parties, a written communication by the use of messaging services and face to face communication via video call services ( Haddon, 2017) . The cell phone also provides the user the ability to use internet services which can be used for communication, research or entertainment. The cell phone user can easily use email services, access social media sites like facebook, tweeter, and Instagram as well as share their views and feelings in the social media platform. Personal and business communication has been made simple since the cell phone since some phones are more sophisticated to assist in monitoring business activities ( Haddon, 2017) . Today the cell phone is used by all people around the world.

Physical Science Concepts the Device Uses
The cell phone uses the basic concepts of radio waves to convey voice from one recipient to another. As one makes a call, the phone converts the voice into an electric signal. The signal is then transmitted in the form of the radio wave which is received by the receiver’s cell phone which converts the received radio waves into sound (De-Sola Gutiérrez, Rodríguez de Fonseca & Rubio, 2016). A cell phone thus comprises a radio receiver and a radio transmitter just like a CB radio or a walkie-talkie. The ability of a cell phone to remain mobile is caused by the presence of a compacted antenna and uses a relatively low amount of power that can be stored in a battery. Cell phones have the greater ability to send a signal over a very long range because of their enhanced transmitters.
For very long range communication, the cell phone utilizes the cellular network cells with a mast or transmission base station which pick up the weak signals to the mast adjacent the receivers cell phone. In a situation where one communicates while on the move, the cell phone changes masts as per its location. Radio frequencies are limited for cell phone networks. Typically there are about 800 frequencies available that one is allocated to the caller or receiver (De-Sola Gutiérrez, Rodríguez de Fonseca & Rubio, 2016). Communication over a long distance requires one frequency allocated by the must near the caller for transmitting the radio waves and one frequency from the mast near the receiver for receiving the transmitted radio waves. For calls within the same area, 400 conversations can overload a bandwidth. Thus, for successful use of the cell phone, there are three important items; the transmitter, the receiver, and the cellular network cells or must boost the radio waves.
