The book is a detailed, top level explanation of the various major wireless standards currently in use throughout the world. To understand the bulk of the narrative, you need a professional background in electrical engineering and communications theory. For example, in one chapter there is a discussion of codes used by these standards, like Gold and VL-Kasami.

There is useful advice about some suboptimal schemes, especially LMDS. This suffers from its signal often being absorbed by rain and foliage. Plus it needs Line of Sight to work. LMDS is best used when the wireless communication is between two fixed (ie. non-mobile) devices. Think perhaps of linking two buildings this way. So that free space optics comes into play.

Asif also points out that for Mobile IP, then using IPv6 is better than IPv4 in 3G (or in an eventual 4G) systems, due to faster handover and built in Quality of Service. And of course, v6 won't run out of addresses.

The last 2 chapters talk about the merging of standards into something that might be called 4G. Yielding a seamless transition in wireless across all length scales. From Bluetooth at meter distances to wide area networks. There is some speculation about possible applications. But this is relatively sparse. If you want a more extensive inquiry into applications, take a garner at this book from the same publisher, 4G Roadmap and Emerging Communication Technologies (Universal Personal Communications).
