Today, mobile communications are connected with a lot of spheres of the people’s life. In their book Introduction to Mobile Communications: Technology, Services, Markets, Dave McNally, Tony Wakefield, Alan Mayne, and David Bowler present the discussion of the main aspects of the modern telecommunication industry.
The research question associated with mobile technologies can be formulated the following way: How do mobile phone’s calls work? The detailed analysis of the mobile technologies provided in Chapter 2 and Chapter 3 of the book is helpful to develop the discussion of the research question.
The source can be discussed as reliable and relevant for discussing the research question because the book is based on analyzing the main principles of the mobile technologies’ work. The examination of the changes in the industry is also presented in the book.
Furthermore, the authors of the work are the members of the ISEB Diploma Board for Systems Analysis and Design and the lecturers of the US universities, specialising in technical communication.
Being professionals in the field, McNally, Wakefield, Mayne, and Bowler provide the complex analysis of the tendencies and basic changes in the modern mobile technologies and telecommunications. The target audience of the book is specialists interested in the development of the industry, engineers, and researchers.
Thus, the topic of the book is mobile communications. The authors’ purpose is to provide the overall analysis of the industry and developed tendencies in mobile technologies. The authors pay attention to all the aspects of the industry, including not only technologies but also market and infrastructure.
The book consists of four main parts which are the summary of the mobile communication market, the analysis of the technology principles, the focus on the aspects of the mobile networks, and the discussion of the services and media associated with the sphere.
To conduct the necessary research on the question of mobile phones’ work and principles of calling with the help of mobile phones, it is important to refer to Chapter 2 “Technology Principles: The Basics of Telecommunications” and Chapter 3 “Mobile Network Infrastructure and Supporting Systems”.
The information provided in these chapters is significant to discuss the principle of mobile phone system’s work in relation to calling, switching, and receiving signals.
In their work, McNally and the group of researchers state that mobile phone communications are the result of developing the radio technology based on the cellular system. This process is in a constant progress because cellular telephony systems are improved to contribute to the quality of a signal (“Technology principles: the basics of telecommunications” 2007, p. 190).
Thus, to realize the call via the mobile phone, it is necessary to rely on the definite cellular system the main components of which are the mobile devices and the cellular base station (“Technology principles: the basics of telecommunications” 2007, p. 190). Mobile phones operate within cells, and the quality of the system depends on the number of channels supported by one cell at a time.
From this point, mobile phones act as low-power transmitters to pass the signal to the cell and connect with the other mobile phone with the help of that cell (“Mobile Network Infrastructure and Supporting Systems” 2007, p. 240-244).
The signal from one mobile phone passes to the definite cell, and it is connected within the cell with the required mobile phone with references to the code and control channel. The specifics of the work of the cellular system determine the quality of the connection and its speed.
It is possible to concentrate on the first 1G system which was changed into 2G systems such as GSM (Global System for Mobile Communications).
The next generation of the cellular system includes 3G systems such as UMTS (Universal Mobile Telecommunication System) (“Technology principles: the basics of telecommunications” 2007, p. 195). Moreover, the authors provide the detailed analysis of the features typical for GSM and CDMA systems.
The information on the principles of mobile phones’ work and discussion of the modern cellular system according to their characteristic features presented in Introduction to Mobile Communications: Technology, Services, Markets is relevant in relation to the research question because the examined chapters of the book provide all the basic material to discuss the aspects of the issue.
Chapter 2 and Chapter 3 can be used for discussing the principles of mobile phone calls and for completing the research successfully.
Notes
Dave McNally, Tony Wakefield, Alan Mayne, and David Bowler are the authors of Introduction to Mobile Communications: Technology, Services, Markets. It is possible to refer to their authority because these persons are the members of the ISEB Diploma Board for Systems Analysis and Design. They are also lecturers of the US universities who specialise in technical and mobile communication.
The book includes four chapters. Chapter 2 is directly associated with the problem of the cellular system’s work which is necessary for realizing mobile phone calls. The section “Radio and Cellular Systems” provides the detailed description of the cellular system’s work (also in schemas). It is important to refer to cell planning, GSM and CDMA-based systems.
Chapter 3 provides the important information about specific technologies used to make calls via mobile phones. The section “Making Calls” is useful to compare the principles of making calls between mobile phones and telephones. The analysis of GSM and GPRS systems is provided.
