Product Description
Master the basics in designing, building, and managing a Cisco Aironet WLAN.
- Master the basics of Wireless LANs with this concise design and deployment guide
- Understand implementation issues for a variety of environments including vertical, SOHO, and enterprise networks
- Learn design and troubleshooting advice from real-world case studies
802.11 Wireless LAN Fundamentals gives networking engineers and IT professionals the knowledge they need to design, deploy, manage, and troubleshoot their own wireless local-area networks (WLANs). Starting with an overview of the technology and architecture of WLANs, the book goes on to explain services and advanced features that such applications can provide. Most importantly, it provides practical design guidance and deployment recommendations.
Wireless LANs connect computer networks via radio transmissions instead of traditional phone lines or cables. Benefits to these systems go well beyond getting rid of all the cables and wires. Campus networks can grow geographically larger while still retaining all their efficiency and speed. Additionally, cost savings can be realized when third-party phone lines are no longer necessary, saving the cost of line rental and equipment upkeep. Finally, flexibility in campus network design increases significantly for the networking professional, while the network accessibility and usefulness increases for the individual users.
802.11 Wireless LAN Fundamentals helps networking professionals realize these benefits by helping them understand how to design, build, and maintain these networks, as well as how to justify their value within organizations.

Good coverage in reasonable depth, By
This review is from: 802.11 Wireless LAN Fundamentals (Hardcover)
Great things sometimes really do come in small packages. I confess I had my doubts when I picked up this book: it seems very small to actually cover the fundamentals of a topic, any topic. But it surprised me. In only about 250 pages, it succeeds in covering how wireless data networking - aka 802.11, or WiFi - actually works. There is even a professional level of detail. When it comes down to it, what makes wireless different is the use of a radio instead of a physical wire. That means, for those familiar with the OSI Model, the differences are all in the bottom two layers, the Physical and the Data Link layers. As an effect of using a radio, of course, anyone with an appropriate antenna can listen in, and maybe join the conversation if they wish, which makes security both important and a little trickier to implement. Now you know the focus of this book. To make sure that the reader understands the data network wireless connects to, as well as to provide a good comparison, the... Read more

This review is from: 802.11 Wireless LAN Fundamentals (Hardcover)
I recently read the title "802.11 Wireless LAN Fundamentals" by Pejman Roshan and Jonathan Leary. ISBN: 1587050773. You've heard the saying that good things come in small packages. Well, this title reinforces that statement. The book is packed with information regarding 802.11 Wireless LAN's. Don't be thrown by the title into thinking that this book only covers the basics. In fact, this book covers the basics and much, much more.The book starts off with fundamental concepts of Ethernet Technologies. Not enough to be a great Ethernet reference, but enough to refresh your memory or to get the flavor of Ethernet once again. The book then explains the essential concepts of Wireless LAN's. After some needed high level concepts are covered the book dives into the bits and bytes of Wireless networking, leaving nothing for the imagination. The physical layer details are covered extremely well in this book. There are great depictions that show the different... Read more

Wireless LAN manual,
By A Customer
This review is from: 802.11 Wireless LAN Fundamentals (Hardcover)
At a total of 281 pages covering 10 chapters of material, this book is very compact, but every page is filled with relevant information.The first chapter of the book quickly delves into Ethernet technologies - 802.3 ethernet frame formats, addressing, CSMA/CD, 10Mb,100Mb and 1000Mb. The second and third chapters cover the physical and MAC layers of 802.11 technology extensively. Chapter 2 starts from service sets (IBSS,BSS and ESS),CSMA/CA and how it differs from CSMA/CD,and moves to 802.11 MAC layer operations. MAC layer operations include station connectivity - how 802.11 clients connect to the access point, power save operation and the different 802.11 frame formats. Chapter 3 covers the physical layer of the 802.11 protocol - the sublayers, PMD (Physical Medium Dependant)and PLCP (Physical Layer Convergence Procedure); FHSS (Frequency Hopping Spread Spectrum) and DSSS (Direct Sequence Spread Spectrum) and the different modulation techniques used in 802.11,802.11a,802.11b...
