Deploying License-Free Wireless Wide-Area Networks 72

Posted by timothy from the you-gotta-license-for-this-thing dept.
Grant Willey writes "Deploying a License-Free Wireless Wide Area Network? Want to learn the intricate details from an authoritative expert who has personally designed and installed hundreds of license-free outdoor broadband wireless networks? This book isn't just for WISPs (wireless Internet service providers), this book is for you!" Read on for Grant's review of Deploying License-Free Wireless Wide-Area Networks from Cisco Press.
Deploying License-Free Wireless Wide-Area Networks
author Jack Unger

publisher Cisco Press
rating 8
reviewer Grant Willey

summary This is an information packed publication designed to assist you with the planning, installation, and maintenance of wireless WAN's.

This information packed publication is designed to assist you with the planning, installation, and maintenance of wireless WANs. You'll receive help with many commonly faced deployment challenges including site surveying, antenna evaluation and selection, overcoming real-world obstacles, solving noise and interference problems, maximizing available bandwidth, and working safely with tower structures and wireless gear. And, if you're presently pursuing a wireless technology certification such as Planet3's CWNA, CWNI, CWSP, etc, this book isn't written as a study guide, but it does provide vitally important information to help you earn these respected certifications.

Whether you're an experienced LAN/WAN professional or are new to the field and looking to "get your feet wet," this book will enrich your knowledge and possibly open new doors of opportunity for you. Being an experienced LAN/WAN professional with 19 years of experience and dozens of certifications, I thank the author for not filling the book with dry-humored jokes, useless "real life" experiences, and confusing diagrams/ illustrations. This book is grammatically correct, technically accurate, focused, and very helpful whether you're pursuing wireless certification or not. Beginner and experienced networking professionals will appreciate the "vendor neutral" content of the book. The book is published by Cisco Press, but contains no specific references to CISCO brand hardware/software. I believe this makes the information even more useful to technicians and installers who work with varying vendor equipment. While many concepts and methodologies are the same, this book is true to its name and offers little help in the way of assisting you with indoor WLAN deployments. The wealth of useful information contained in Appendix B, "Wireless Hardware, Software, and Service Provider Organizations" is absolutely priceless and much appreciated.

Here's how the book is organized: Chapters 1 and 2 are an introduction to wireless WANs and explain wireless technology fundamentals. Chapters 3-5 dive into network architecture, conducting site surveys, and selecting appropriate antennae. Chapters 6-9 discuss actual equipment selection, installation, interference resolution, and the provision of broadband wireless Internet access. Chapter review questions are located at the end of each chapter and serve as a "pop quiz" to reinforce key concepts and technologies covered.

Comparing this book to others is relatively easy. I haven't found any other publications dedicated to the planning, installation, and maintenance of wireless WANs! While there are a plethora of theoretical RF and wireless technology books already in print, no single publication dedicates its content to explaining the technologies like this book does. In addition, I appreciate the author's strong emphasis on installation and technician safety -- an area not many authors seem to write about. This book will not bog you down in theoretical RF discussions, but rather allows you to learn through the introduction of real-life examples, explanations, and suggestions based on the author's actual installation experiences.

The book contains no CD-ROM or marketing material. Published in March 2003 (prior to the now finalized 802.11g standard), the book primarily covers 802.11a and 802.11b technologies. Both Mr. Unger and Cisco Press deserve a round of applause!

    • I think a "real-life example" [as the review uses it] would indicate a generic example that would be found in life. The generic and therefore broad nature would allow for a more general descriptoion that and hence an understanding of the concepts, so as they may apply the general knowledge to a wider variety of situations. Where as a real-life experience would tell us how to do one thing very well, but only in those specific circumstances.

    • More and more "book reviews" are becoming less and less review-like and more and more marketing. Wasn't there a book "review" some time ago that introduced the word marketectual? It was aimed at marketing software products or something and every piece of review on here was loaded with acronyms, buzzwords and various hi-tech sounding catchphrases.

    • Reviews I write go to multiple sites (/., amazon, etc). Who cares, as long as it's the case of the same person writing the same review in each place? If you plagarize another person's review, that's another story.

    The more interesting part of the problem is the backhaul. Great, you set up a couple of access points and provide access to your entire apartment building or neighborhood. What's the backhaul connection? DSL? T3? Unless you're talking about provisioning something on ther order of OC3 or a DS3 you have the potential of bottle-necking pretty quickly. The bandwidth has got to come from somewhere. That's why I believe the 802.16 spec is the last-mile answer, not WLAN. We've [beamreachnetworks.com] addressed that problem, has anyone else?
    • Jeez, if I thought the review was a thinly disguised commercial...the parent post is quite obviously one.

      P.S. I never hear anyone but marketing guys call it "backhaul".

    • Okay, so now there is no difference between 'backhaul' and 'last mile'? you marketing guys have all the answers, huh.

      In most corp. networks the local access layer is Fast-E, connected to a T1 Interenet pipe, so what's the difference?

    What about WANs that use 900 MHz? Those higher 802.11x frequencies are very common, but when faces with a lot of trees, hills, etc you want something that has less signal loss through obstacles. The equipment is definitely available [waverider.com].

    I am surprised that the book does not cover this technology because the spectrum is license free (at least in Canada and the USA) and it has a lot of potential for Wider Area Lans in hilly, forested, wooded areas like my own.

      The author and I worked together in 1997, just as he was starting to transition from 900 MHz to 2.4 GHz equipment. At the time he was seeing some pretty serious interference problems with 900 MHz in the south SF bay - presumably due to the boom in 900 MHz cordless phones. Rest assured he has a lot of experience with that band, so I don't know why he wouldn't write about it, unless he doesn't consider it viable for modern installations.

      One interesting thing about 900 MHz is that although the free air path loss and absorption by vegetation is indeed lower vs. higher frequencies, it's also more difficult to deploy antennas with gains like you find in the 2.4 and 5.7 GHz bands. I'm talking mostly about point-to-point deployments. In designs I've done, the system loss (calculation of amount of energy arriving at the remote receiver), assuming antennas of reasonable size, was almost the same for 900 or 2.4. One significant advantage of 2.4 is an 83 MHz band to play with vs. a 26 MHz band on 900. I wouldn't say that kind of equivalence applies to 5.7 though, due to the environmentally-related fade factors starting to really kick in.

      I have a lot of respect for Jack and his commitment to wireless, and hope his book sells a gazillion copies. He's a fellow ham radio operator and knows the RF side far better than most wireless LAN/WAN people I've met.

      • It's a myth that the free space path loss increases with frequency. The free space path loss is independent of frequency. Think about it: If the path loss of electromagnetic radiation increased with frequency, we'd never see any light from the sun--at 500,000,000 MHz [qsl.net], it'd be severely attenuated!

        The effect often seen is due to the antennas used, not the frequency of operation. WLANs often use resonant dipole antennas. Such antennas have constant gain with frequency; a 900 MHz resonant dipole has the

        • As soon as you're not in free space, though, high frequencies tend to get aborbed faster.

          For example, one brand of high-quality coaxial cable loses 3.7 db per 100 feet at 900 MHz. At 2500 MHz, it's up to 6.5 db per 100 feet.

          Similar things happen when there are buildings, trees, people, and other obstructions. It's analogous to what happens when you're a few hundred feet from a stereo and you mostly hear the bass.

    I got this book a few months ago, and it was one of the best books I've purchased. For a book from Cisco Press, there is almost no mention of specific Cisco products, which was surprising...but freshing in a way.

    Granted, it's weaker in the areas of security and such, but it is pretty heavy on RF theory and all those things you need to make any license-free WWAN work.

    Security and stuff is important as anyone here will likely agree to, but that is really better covered in dedicated books on the topic. In short, this is not a general book about wireless networking. It is techincal and there's a lot of useful information for people who are above the noob level of wireless looking to install outdoor wireless link.

    The best part of the book, IMHO, was the antenna theory portions, math, and formulas that were included. The author is a ham radio operator (as am I) and he defintely know what he's talking about.
