HSPA Performance and Evolution 
A practical perspective

Written from an operator’s viewpoint, HSPA
Performance and Evolution explores the lessons learned
and techniques developed for optimally deploying HSPA (High Speed
Packet Access). The essential distinctions between rolling out HSPA
compared to earlier UMTS and GSM technologies are explained
covering the many issues that must be specifically handled. Areas
in standards which have been left open for interpretation, causing
significant differences between vendor implementations, are
identified and solutions explored.

This book is invaluable in enabling wireless operators to
extract maximum performance offered by 3GPP’s HSPA radio
technology, consisting of both downlink (HSDPA) and uplink (HSUPA)
elements. It focuses on real-world performance, sharing practical
implementation methods and tradeoffs for deploying, optimizing and
maintaining networks using the HSPA air interface.

* Examines algorithms, equipment and performance perspectives to
identify and explain HSPA

* Measures performance and sets network parameters for optimal
tradeoffs

* Presents results from practical and real-world network
performances

* Explores the evolution of HSPA technology into HSPA+ and
eventually next generation LTE technologies
