Focusing on the fundamentals of wireless communications and networking, this book introduces readers to an overview of the salient features of first and second generation wireless cellular systems, and those perceived for the third generation, with a road map. It identifies the problems that cause information loss in point-to-point signal transmission through the wireless channel, and discusses techniques suitable for minimizing the information loss. With an acceptable transmission quality, the text proceeds to cover wireless communications in a cellular setting, treating the ramifications in terms of capacity maximization, support for multi-user transmissions, mobility management to facilitate user roaming, and global information delivery through wireless/wireline interworking. For individuals beginning their study of electrical and computer engineering.
