HSPA turned out to be a revolutionary technology, through making high-speed wide-area data connections possible. HSPA is by far the most global mobile broadband technology and is deployed by over 500 operators. Data volumes today are substantially higher than voice volumes and mobile networks have turned from being voice dominated to data dominated. The fast increase in data traffic and customer expectation for higher data rates require further evolution of HSPA technology. This book explains HSPA evolution, also called HSPA+. The book is structured as follows. Chapter 1 presents an introduction. Chapter 2 describes the basic HSDPA and HSUPA solution. Chapter 3 presents multicarrier and multiantenna evolution for higher efficiency and higher data rates. Chapter 4 explains continuous packet connectivity and high speed common channels. Multiflow functionality is described in Chapter 5, voice evolution in Chapter 6, and heterogeneous networks in Chapter 7. Advanced receiver algorithms are discussed in Chapter 8. ITU performance requirements for IMT-Advanced and HSPA+ simulation results are compared in Chapter 9. Chapters 10 to 13 present the practical network deployment and optimization: HSPA+ field measurements in Chapter 10, network planning in Chapter 11, network optimization in Chapter 12, and smartphone optimization in Chapter 13. Terminal design aspects are presented in Chapter 14. The inter-working between LTE and HSPA is discussed in Chapter 15 and finally the outlook for further HSPA evolution in Chapter 16. The content of the book is summarized here in Figure P.1.
