Cellular devices have evolved and technologically advanced significantly over the last couple of decades. There are many uses to this technology it ranges for something as simple as cordless phone calls, text messages, and even surfing the web. This technology can be thought of as a system just like any other technology because it is dependent on a lot of other components than just the cell phone by itself. Cell phones all need to have a provider company who gives the cell phone signal from a tower. Cell phones are made up of similar technology found in computers or laptops. Cell phones have a rechargeable battery that allows them to be cordless and portable.
Astonishing, over the course of 40 years the dynamic way handheld technology has evolved, from humble beginnings, in the 1970’s with Martin Cooper being the first person noted to make a cellular phone call in public to now over six out of the seven billion people have cell phone. Cellular technology in which enables people to call beyond any border and share unlimited information at any moment.
Cellular phone is a wireless and hand-held device that is well known to the public. It is very common to have a cellular phone now a day since cell phone was introduced to the United States in 1983. According to the wireless industryfs trade association, Cellular Communications & Internet Association, there are over 135 million subscribers in the United States at the time of this writing. It estimates that there will be over 200 million cellular phone subscribers in world wide by the year of 2005.
Cell phones receive and send radio signals with any number of cell site base stations that are fixed with microwave antennas. These sites are usually fixed on a pole, tower or building and placed throughout settled areas then connected to a cabled communication network and switching system. Phones have a low-power transceiver that broadcasts voice and data to the closest cell sites. A cellular repeater maybe used at places where there is low coverage, which uses a long distance high-gain dish antenna to communicate with a cell tower located outside the normal range, and a repeater, to re-telecast on a short-range local antenna that permits any type of cell phone within a few meters to function correctly.
Cell phones have been around for decades. Cell phones were first used in mobile rigs, in taxis, police cars, and other emergency vehicles and situations (Chowdhury, R). The public was introduced to the first generation phone in 1983. These cell phones had small batteries but as society went growing it went getting bigger. As phones became wireless they shrank in sizes and increase sudden ability as tech improved. The startling idea of data services was not thought of, most inclusion areas were for enormous cities and interstate. (Walz,2011).

Cellular phones are a phenomenon that has engulfed people in the nineties. They have become a common occurrence whether you are waiting in line at the super market or in a movie theatre. One professor at Murray State University said, “Many students are carrying them, I had a student get a call in the middle of a test last semester.” Although many people have accepted the thought of carrying a telephone wherever they go, others have not taken the onslaught of cell phones quite so easily. Cell phones have become part of everyday life, and with the dramatic changes that have been made, there is no sign of their existence diminishing. Today, cellular service is available in all 306 Metropolitan Statistical Areas across the country and all of the 428 Rural Service Areas.
Telecommunications gained mainstream attention in the early 90’s; however the initial key market was business men and women, who used their phones whilst being on the move and so allowing them to communicate with their companies with ease. Though in the modern era, telecommunication went through segmentation in the market trends, and now in this day and age it would be difficult to find someone who does not own some form of mobile technology. Many phone providers battle to provide the best service for their customers (Figure 1).
A cell phone is a small wireless device that has some of the same functions of a standard wired telephone. It is also a smaller device and more mobile. A cell phone is also known as a mobile phone or mobile device. Cell phones are known to have more functions than a standard wired telephone. A subscription to a particular service and a prepaid or a monthly billing setup is required as well.
G in 1G, 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services a higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. During the time of 1G, radio signals were transmitted in ‘Analogue’ form. 2G networks on the other hand, were based on narrow band digital networks. The 3rd generation of mobile networks has become popular and users access the Internet over devices like mobiles and tablets. This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos, play games and much more. 4th Generation mobile networks are believed to provide many value added features.
