Publisher Description

A comprehensive reference book codifying the various standards releases for High Speed Packet Access (HSPA) wireless technology HSPA evolution has maintained its prominence through Releases 7-11 but the evolution is coming to an end with Release 12, with the focus moving to LTE. However, HSPA network and terminal sales will continue for many years: HSPA is expected to remain as the number one radio access technology from the sales point of view far beyond 2015. This timely book examines the complete HSPA evolution, and will be the ultimate long term reference for HSPA evolution. Headed by the successful editing team of Holma, Toskala and Tapia, industry experts look at HSPA evolution including complete Release 11 and the main additions in Release 12. They describe 3GPP definitions, field measurement, expected performance, practical optimization guidelines and the implications to the devices and to the networks. The book also covers MIMO antenna solutions and multicarrier evolution to provide higher data rates. Dedicated chapters include Continuous Packet Connectivity and High Speed Common Channels which provide major improvement to the smartphone capacity, end user performance and power consumption. The book assumes basic understanding of mobile communications yet the material is presented in an understandable way which can be enjoyed without any pre-information about MIMO or other technology solutions.

Back Cover

A comprehensive reference book providing an in-depth presentation of HSPA+ evolution, network planning and optimization, and terminal design solutions. Headed by the successful editing team of Holma, Toskala, and Tapia, industry experts look at HSPA evolution from 3GPP Release 7 to Release 12. The presentation covers MIMO antenna solutions, multicarrier evolution, Continuous Packet Connectivity (CPC), high speed common channels, and HSDPA Multiflow. The network optimization is based on extensive field experience from high loaded HSPA+networks to show solutions for maximizing data rates, minimizing interference, managing multiband deployments, heterogeneous networks, and optimizing spectrum refarming. The smartphone section shows the impact of the operating system and application on the network data and signaling traffic and on the end user performance. The terminal RF chapter gives a detailed explanation of the latest implementation solutions for multimode and multiband terminals with a special focus on power consumption minimization. The book assumes a basic understanding of mobile communications yet the material is presented in an understandable way and can be enjoyed without any pre-information about technology solutions.
