assignment was more challenging than she had imagined. Churn Management in the wireless industry was really complicated, but Sarah was excited to be working on perhaps the most important marketing issue facing Cell2Cell, one of the leading providers of cellular telephone service. Sarah’s mission, as described by her boss, Charles R. Morris, was to (1) develop a statistical model for predicting customer churn, (2) use the model to

Daniel Moore College Composition II Mrs. Price October 14th 2014 “Motorola was a true pioneer in personal communications. We introduced the world 's first commercial portable cellular phone. We even invented the groundbreaking Six Sigma quality improvement process, which became a worldwide standard for excellence”(Motorola.com). Motorola is a proud and well known technologies manufacturer and has been in the cell phone industry from the start. In fact, Motorola manufactured the first commercial

Abstract— The next generation wireless networks are the fourth generation (4G) networks which are targeted for various applications; voice, data and multimedia communications. The mobile technologies 1G, 2G and 3G have lot of disadvantages which has led to the invention of 4G. As the users of mobile devices increase the demand for faster and efficient communication in the mobile network also increase. 4G aims to provide the quality of service (QoS) guarantee for many applications, is an important

called mobile phone or mobile device.—BusinessDictionary.com A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public

An approach widely used on mobile phone navigations is cellular networking based localization. The global deployment and general availability of cellular

Introduction IMSI Catchers or Cell-Site Simulators are devices that pose as legitimate cell phone towers on GSM networks in order to either log the IMSI numbers of mobile phones in a specific area or to intercept mobile phone traffic in a specific area of interest. IMSI stands for International Mobile Subscriber Identity and is an identifying number that is unique for every mobile phone. This research paper sets out to understand how IMSI catchers work, when and in what context their deployment would

phone to a compact device containing the capabilities of a computer. According to Russell Ware, a cell phone is “any portable telephone which uses cellular network technology to make and receive calls.” A cell phone works through a maze of cellular towers that cross the world. This connects mobile devices that allow texting and calling between two cellular devices. Motorola produced the first commercially available cell phone which officially went on sale in 1984 (Ware). This cell phone was called the

have been used in telecommunications since the mid-1960s. For a decade or so, they carried the bulk of international telephone calls, which they still do on routes to small and developing countries. In addition, VSAT (very small aperture terminal) networks provide essential communications for large companies, big ships, and disaster relief. But the use of satellites on any wider scale has been ruled out by their traditional disadvantages (high cost, expensive and bulky terminal equipment, and annoying
