Multimedia Wireless Networks: Technologies, Standards and QoS Review

Average Reviews:

(More customer reviews)The book is cooking together information about WLAN, 802.11, 802.16, Bluetooth, 802.15, GPRS, UMTS and so forth. It gives a rudimentary overview of mostly the MAC of each standard (and sometimes also PHY and some higher layer protocols), especially with respect to available QoS mechanisms.
Unfortunately, the book only scratches on the surface of each standard. It fails to give the big picture, instead it provides a mosaic of gory details. Sometimes, the pieces selected for presentation seems to be randomly selecled.
The book describes "what" is in the standard (at least some pieces of it) but it fails to explain "why" things are like they are. The reason might be that the authors have not aquired a fundamental understanding of each of the standards presented. (It might be useful as a strange kind of manual, but not at all as a tutorial of any kind.)
Finally, the book needs editing. It is frustrating with chopped figures, strange font policies for headings, and so forth.
The book deserves a star because the last pages of Ch.2 and most of Ch. 3. provided a good overview of QoS that laid a basis for the rest of the book. Also, it must have been quite much work for the authors to gather together all this (incomplete pieces of) information from various standards.

Now that you can buy a cell phone with integrated multimedia capabilities, integrating QoS is even more important and timely since development and maintenance of those networks is crucial to product success! This book introduces the wireless networks practitioners (designers, implementers, and users) to the art of a wireless system design with integrated QoS support. To ensure users quality satisfaction, end-to-end Quality of Service (QoS) support is needed the various underlining networks combined of the wide area network (WAN), the last mile distribution system (WLLs, satellite), and the WLANs. Wireless networks should be designed with integrated QoS control techniquesWith the growing optical based WANs users enjoy an abundance of bandwidth that results in no need for exercising QoS control schemes at the WANs because the edge wireless networks will suffer in the foreseeable future from limited unstable bandwidth (i.e. - unstable QoS). This trend is also observed in the new WLAN and WLL approved and proposed standards. These standards include however only the signaling mechanisms for QoS - not implementation techniques! The QoS techniques implementations are left to the designer.And designer's will turn to this book for answers.
