Free download Free Next Generation Wireless LANs from mediafire, rapishare, and mirror link If you've been searching for a way to get up to speed on IEEE 802.11n and 802.11ac WLAN standards without having to wade through the entire specification, then look no further. This comprehensive overview describes the underlying principles, implementation details and key enhancing features of 802.11n and 802.11ac. For many of these features the authors outline the motivation and history behind their adoption into the standard. A detailed discussion of key throughput, robustness, and reliability enhancing features (such as MIMO, multi-user MIMO, 40/80/160 MHz channels, transmit beamforming and packet aggregation) is given, plus clear summaries of issues surrounding legacy interoperability and coexistence. Now updated and significantly revised, this 2nd edition contains new material on 802.11ac throughput, including revised chapters on MAC and interoperability, plus new chapters on 802.11ac PHY and multi-user MIMO. An ideal reference for designers of WLAN equipment, network managers, and researchers in the field of wireless communications.Books with free ebook downloads available Free Next Generation Wireless LANs [Kindle Edition]

Several months ago, I started on a project that required me to be able to dig into low-level 802.11n device driver code and understand how it worked. I knew nothing about 802.11 at the time, and it quickly became apparent that the 802.11 standards documents were not written with the neophyte in mind. I looked around for books to get me started, but most were focused on network design and implementation, and they weren't much help in understanding the frame-by-frame details.
Then I found this book.
Perahia and Stacey provide a lucid introduction to the structure of 802.11n (and ac). They focus on the improvements in the more recent "n" and "ac" amendments, but they give enough 802.11 a/b/g background to avoid leaving anyone behind. Most valuable of all, they explain the motivation behind many decisions made in the standardization process--which offers a whole new layer of insight into why 802.11 works as it does.
The book has separate sections on the physical and MAC layers, and each is self-contained. The prose is both concise and understandable, which means you don't have to set aside days of reading to get what you need. All-in-all, this is one of the most well-written technical books I have come across.
Of course, if you need to work with 802.11n on an implementation level, you'll eventually have to dive into the standards documents themselves, but if you take the time to read this book first, you'll save yourself hours of piecing together details from disparate sections (and documents) to answer what you thought was a simple question.

Perahia and Stacey have a very straight forward way of writing and get right to the meat of what you need to know to understand and use WLAN effectively, or to create your own implementations. The book contains all the technical details you need to understand the IEEE 802.11 standards (which on their own can be a little cryptic if you are not a regular at IEEE meetings). In addition to being a great reference book, you will also find history and reasons for choices made in the standard. There are lots of practical information about how features are commonly used, recommended practices, features that are not commonly used (hint: you don't have to learn all 3000+ pages of the latest WLAN standard!). This is the book I wished I've had when I started designing WLAN systems. Now with several years of experience under my belt I still find this book an invaluable companion in my work. You will find solid analysis and explanations of RF, Phy and MAC layer protocols and you will find detailed information about all the new features for enhanced robustness and throughput, such as MU-MIMO, aggregation and beamforming. I would highly recommend this book for every systems, hardware, RF or software engineer that needs a deeper understanding of WLAN!
