What is Mobile Cellular Communication?
Mobile cellular communication is a form of wireless communication that uses radio waves to transmit voice, data, video and other information over a network of base stations (or cell sites) that are connected to a central switching system. The network is divided into smaller areas called cells, each served by a base station. The base stations communicate with mobile devices (or handsets) that can move from one cell to another without losing connection. Mobile cellular communication enables users to communicate with each other anywhere within the coverage area of the network.
Mobile cellular communication has many applications in various fields such as personal communication, business communication, emergency services, entertainment, education, health care, transportation, military, etc. It has also revolutionized social interactions, information access, and economic development. Mobile cellular communication is one of the fastest growing and most dynamic sectors in the world today.

Introduction to Mobile and Cellular Communication Systems
This chapter introduces the basic concepts of mobile and cellular communication systems, such as the history and evolution of wireless communication, the types and characteristics of wireless channels, the classification and comparison of wireless systems, the components and functions of cellular systems, the cellular network architecture and operation, the cellular system capacity and coverage, and the challenges and trends in mobile communication.
Cellular Geometry, Frequency Reuse, Cell Splitting and Sectoring
This chapter explains the principles and methods of cellular geometry, frequency reuse, cell splitting and sectoring. Cellular geometry is the study of the shape, size, and arrangement of cells in a cellular network. Frequency reuse is the technique of using the same frequency band in different cells to increase the system capacity. Cell splitting is the process of dividing a large cell into smaller cells to improve the system performance. Sectoring is the technique of dividing a cell into sectors to reduce the co-channel interference.
Elements of Cellular Radio System Design
This chapter describes the elements of cellular radio system design, such as the link budget analysis, the power control techniques, the handoff strategies, the diversity schemes, the equalization methods, the channel coding techniques, the modulation schemes, and the multiple access techniques. These elements are essential for designing and optimizing a cellular radio system that can provide reliable and efficient communication over a wireless channel.
This chapter discusses the sources and effects of interference in wireless communication systems. Interference is any unwanted signal that degrades or disrupts the desired signal. Interference can be classified into two types: external interference and internal interference. External interference comes from sources outside the system, such as natural phenomena or other wireless systems. Internal interference comes from sources within the system, such as co-channel interference or adjacent channel interference. Interference can cause various problems such as signal distortion, noise enhancement, bit errors, call drops, etc.
Co-Channel Interference Models and Reduction
This chapter presents the models and methods for co-channel interference reduction in cellular systems. Co-channel interference is the interference caused by signals from other cells that use the same frequency as the desired cell. Co-channel interference depends on factors such as the frequency reuse factor, the cell geometry, the propagation environment, the antenna pattern, etc. Co-channel interference can be reduced by techniques such as cell splitting, sectoring, frequency hopping, channel assignment algorithms, smart antennas, etc.
Teletraffic Engineering Trunking GoS and Operational Techniques
This chapter introduces the concepts and techniques of teletraffic engineering trunking GoS (grade of service) and operational techniques in cellular systems. Teletraffic engineering is the application of mathematical models and statistical methods to analyze and design telecommunication networks. Trunking is the technique of sharing a pool of channels among a group of users to improve resource utilization. GoS is a measure of the quality of service that a user can expect from a telecommunication network. GoS is usually expressed as a probability or a percentage of calls that are blocked or delayed due to insufficient resources in the network. GoS depends on factors such as the traffic intensity, the number of channels, the channel allocation algorithm, the trunking efficiency, etc.
Basic Antenna Theory
This chapter covers the basic antenna theory, such as the antenna parameters, the radiation pattern, the directivity, the gain, the beamwidth, the polarization, the input impedance, the bandwidth, the efficiency, etc. It also explains the types and characteristics of various antennas used in wireless communication systems, such as dipole antennas, loop antennas, horn antennas, reflector antennas, array antennas, etc.
This chapter focuses on the mobile antennas used in cellular systems. It discusses the design and performance of mobile antennas, such as whip antennas, helical antennas, microstrip antennas, etc. It also describes the effects of mobile antenna environment on the radiation pattern and impedance of mobile antennas. It also introduces some advanced mobile antenna techniques such as adaptive antennas and smart antennas.
