understanding of wireless data made easy

in general the author writes well and presents the material in an easy to understand manner. I read more carefully 2 chapters: chp 9 on IPv6 and Chap 11 on evolution to 3G. In Chp 9, the author gives a good overview of the shortcommings of IPv4 and some additional motivations for designing IPv6. Then, the author highlights some key features of IPv6 e.g. address allocation, mobility support, auto configuration etc. In Chap 11, the author describes briefly how GPRS works and the motivation for moving to 3G. The author provides a good high level description of UMTS and the various features available in different releases of UMTS. The author explains how QoS and security is supported at UMTS and compares UMTS with cdma2000 development.
