Radio frequency spectrum utilization for wireless communication has become a mainstay for global communication despite spectrum congestion and exhaustion. This has made it paramount for radio frequency network planning and optimization engineers to seek means to extend and as well reuse the scarcely available spectrum which definitely bothers on spectrum management. This book provides industry and academic research details for radio frequency planning with microcell (small cell) deployment. It details the background information of cellular systems based on hierarchical classifications while providing practical scenarios to network planning, optimization and microcell deployment for coverage and capacity improvement. This book is a reference guide for both beginners and experts in the telecommunication field.
