Дополнительное описание

IEEE 80. 1 Handbook: A Designer's Companion familiarizes system network architects, hardware engineers and software writers with the basic concepts, terminology and key specifications of the IEEE 80. 1 standard - serving as an indispensable primer

IEEE 80. 1 standard - serving as an indispensable primer. This book takes the reader from a basic understanding of WLANs through the details of the PHY and MAC layer of the standard. The authors articulate a clear picture of the standard to both first-time and experienced designers of wireless products.

The draft standard was ratified on 24 June 2004. This standard specifies security mechanisms for wireless networks, replacing the short Authentication and privacy clause of the original standard with a detailed Security clause.

IEEE 80. 1 Control Frames. Figure 4-5 shows the format of all six types of Control frames, which are all very short. The usage of the ACK in IEEE 80. 1 actually serves to indicate to the sender whether a collision has happened. A collision is inferred by the lack of an ACK. PS-Poll. The PS-Poll (Power-Save Poll) Control frame (20 octets) is used when a STA sees that an AP has frames buffered for it.

DTI is mainly a data transmission period. It is noted that not all the DMG STAs have the opportunity to transmit during DTI. A DMG STA which intends to initiate a frame exchange in DTI shall meet one of the following two conditions: (1) during a CBAP in which the STA is identied or included as source or destination

The first generation 80. 1 wireless market, once struggling to expand, has spread from largely vertical applications such as healthcare, point of sale, and inventory management to become much more broad as a general networking technology being deployed in offices, schools, hotel guest rooms, airport departure areas, airplane cabins, entertainment venues, coffee shops, restaurants, and homes. 1 Handbook : A Designer's Companion.

If you are an engineer with need to quickly understand the details of the 802.11 protocol, but do not want to plow through hundreds of pages of the IEEE specification, this book is for you. It is a good concise treatment of the details of the protocol. It is written for practicing telecommunications engineers. It is not 'wireless 101' and it is not for someone who wants to know how to set up a home or enterprise 802.11 network. It does not describe what unratified (as of this writing) 802.11e, 802.11 g, 802.11i specs are. It does cover the 802.11a and 802.11b phy layer descriptions.
Unfortunately, the lack of a detailed Table of Contents, lack of any index at all, a super sparce list of acronyms hurt the readability. This also makes its use as a quick reference not so quick. I also think that the figures are too simple and that better use of detailed figures would help the book considerably. However, the actual IEEE spec has very good figures. This book and the IEEE spec are side by side companions on my bookshelf and complement each other nicely.
I have found other books to date on the subject much too soft as far as technical detail on the protocol mechanisms. The authors participated in the design of 802.11 and know how to present the most salient features for embedded engineers. If you want a concise explanation of the 802.11 spec, and already have a fundamental understanding of how ethernet works, this is the book for you. So, I give it 4/5 stars on applicability of this content, but not for literary style and construct.
If you are more interested in what is a wireless LAN, what affects the signal propagation, how do you plan to put in an 802.11 LAN in your enterprise, and a little overview on the protocol, buy the James T. Geier book

I received my copy of the IEEE 802.11 Handbook 2nd edition on April 1st, 2005. All experienced Wi-Fi professionals should have this book and those new to Wi-Fi should learn the basics elsewhere.

What follows is a comparison of the two editions.

The same two authors are credited with authoring both editions. Both have significant IEEE 802.11 standards committee histories and business involvements. The authors dedicated the 1st edition to their parents and the 2nd to their wives. Times change.

The 2nd has twice as many pages, and is twice as thick. It is an extra inch wide and tall but with a larger font that results in the same amount of information on each page. Thus the content looks to have doubled.

All the old chapters are carried forward with nominal changes. The 2nd has a very modest glossary and a decent index; the 1st had neither.

New chapters in the 2nd include 802.11i, 802.11e, 802.11h, 802.11d, 802.11F, 802.11j, 802.11g, and 802.11n, in that order but mingled with the old chapters. The entirely new chapters are 4, 5, 6, 7, 8, 13, 14, and 15.

Virtually all the graphics of the 1st are carried forward in the 2nd and most became grainier. Most typos and awkward English in the 1st are corrected in the 2nd.

Someone formatting the 2nd went overboard globally replacing words and phrases with acronyms or abbreviations. For example all instances of "station" became "STA" regardless of context.

Most other changes are additional paragraphs or additional sentences added to existing paragraphs. Rarely is a sentence modified. Here are the 2nd edition pages that have changes in the chapters carried over from the 1st: 5, 14, 26, 27, 33-34, 40, 52-55, 57, 60-72, 74-86, 89, 92-93, 223, 225-226, 228, 239-240, 258-260, 267, 271, 273, 275-284, 289-290, 344-347. If you have a 1st edition you can match the paragraphs up with the 2nd edition and the new material will jump off the page.

The result is a mix of voices from 1999 and 2005. Understanding this makes it easier to forgive a leftover remark from 1999 that would be a glaring mistake if penned in 2005.

The Handbook is seldom technically wrong. The 1st edition introduced language not found in the IEEE 802.11 standard that can both help and hinder accurate understanding of the technology. None of this was improved on in the 2nd edition.

The 1st edition was my only 802.11 resource for several years. When I began reading the IEEE 802.11 document and its amendments I had to stop reading the Handbook in order to not confuse the two. Perhaps one day I can write about what I would wish to see changed in a third edition.

I found the 2nd edition new chapters to be very informative and alone worth the price of the book. So enjoy -- but be careful.

I hope this helps. /Criss Hyde

I don't mind paying a small fortune (>100$) for a large, thick technical book crammed with valuable information; but this tiny handbook is just a *very* thin and *very" small paperback. And they didn't even bother to write an index for it. This is, by far, the most overpriced book I have ever purchased -- or indeed, that I have ever even *seen* in any bookstore, library, or online! 29.95$ would have been more than a fair price for the information and content contained in "The IEEE 802.11 Handbook: A Designer's Companion", not the 60$ or so that is being charged for it.
