RFID for Dummies

Who This Book Is For

Whether you are just curious, scared, worried, or simply mad at the prospect of implementing yet another new technology — even if you know nothing about RFID — RFID For Dummies is here to help. And, unlike a similar promise by the IRS, this book really will help. You find out what RFID is, what it does, and how it works. I guide you through the concepts and ideas in plain English, walk you through the basics of RFID from a business perspective, and specu­late on where this technology is headed (although I do, from time to time,

About This Book

This is a book that is on a mission to take the confusion out of RFID. RFID is based on well-known laws of physics. It’s easy to understand how things work after you get your arms around those basics. The better news is that the technology works really well if you know what you’re doing. So without sending you to MIT for a couple of years of RF engineering school, this book explains everything you need to know to start setting up and deploying your own RFID network — what more could you ask for? provide sufficient Geek Speak for the engineers and systems guys who, no doubt reluctantly, bought this book in an attempt to actually understand the mechanics of Radio Frequency Identification).

If you know the basics about running a laptop or PC and know what an IP address is, you are armed with just about all you need to know to initially set up an RFID network. If you have any background in physics and understand some things from an electronics perspective, you’ve got a running start. I assume that you come from a supply chain or warehouse background and might not have a detailed IT background.

How This Book Is Organized

RFID For Dummies is broken into six different parts. If you are new to the technology, it is helpful to read the parts in sequential order. If you have a physics or RF background and you want to get into the nuts and bolts of the technology, skip right to Part II and then move on to Part III. If you are trying to justify the RFID project, you may want to go right to Part V, which addresses some of the business concerns around strategic planning and ROI. You can read all the technical chapters in Parts II and III by themselves and use them for reference, as well as the last part, the Part of Tens. Here’s a quick rundown of what you’ll find in each part.

Part I: Now That You Can Spell RFID, Here’s the Rest of the Story

This part introduces the basics of RFID. In Chapter 1, you find an overview of the technology, what advantages are driving the mandates, and a blueprint for implementing RFID, which I call the four Ps. In Chapter 2, I explain how RFID fits into the world of Auto-ID technology and explain some of the basics about the protocols that make it work. Chapter 3 helps you start assessing the impact RFID will have on your business and helps you make some basic decisions about how you’ll use RFID.

Part II: Ride the Electromagnetic Wave: The Physics of RFID

In this part, I peel away the layers of RFID to uncover the underlying science of RFID. This part gives you the physics knowledge you need in order to design your network for optimal performance and make wise purchases. In Chapter 4, you can find an overview of how the physics of RFID systems work. Chap­ter 5 digs a little deeper by delving it parts inside each of the key components of a system. Whereas Chapters 4 and 5 focus on the invisible realm of electro­magnetic waves, Chapter 6 is focused squarely in warehouse or marketplace, covering common setups of RFID systems and case studies so that you can learn from early adopters.

Part III: Fitting an RFID Application into Your World

This part is your key to designing an RFID network specifically for your envi­ronment and needs. In Chapter 7, I walk you through the process of testing for electromagnetic noise in your warehouse or building using a spectrum analyzer. Chapter 8 helps you set up a lab (or find one you can use) so that you test for the right tag (Chapter 9) and tag reader (Chapter 10). And last but not least, Chapter 11 helps you wend your way through maze of middle­ware (the software the connects the RFID network) by explaining what fea­tures to look for and how to fit middleware into your network architecture.

Part IV: Raising the Beams for Your Network

This part walks you through the process of actually implementing your care­fully planned-out RFID network. Chapter 12 explains a few project management tools that will keep your trial run and follow-up network designs on schedule. Chapter 13 covers the process of setting up the hardware in the warehouse, or other real-world setting (as opposed to a lab), and how to train your employees to use the new system. And Chapter 14 explains now to set up monitoring systems for both operators and system administrators, so that your system keeps running strong, and thus helps your bottom line.

Part V: How to Speak Bean Counter

Deploying an RFID system is a big project, and the bottom line needs to drive your implementation. This part walks you through the key RFID-related busi­ness decisions you need to make. In Chapter 15, I explain who in your organiza­tion needs to be involved in these decisions and walk you through a nine-step process for building and presenting a business case study. In Chapter 16, I explain strategic benefits you need to include in the business case in more detail, including how to calculate return on investment, or ROI, for all the money you’re about to spend on RFID hardware and software. Chapter 17 is your guide to outsourcing: I explain how you decide whether to outsource, what to look for in an outsourcing partner, and how to seal the deal.

Part VI: The Part of Tens

No For Dummies book is complete without a Part of Tens. The four chapters in this part offer (more or less) ten equipment vendors to assess, ten of the best RFID-related Web sites, ten tips from RFID experts who are part of that rare fraternity that has actually done real-world deployments and lived to tell about it, and ten standards and protocols for RFID that you may want to investigate.

In the back of this book, you can also find a glossary of electrical, magnetic, and scientific terms. So if, in your RFID reading, you come across terminology that leaves you baffled, you can use this glossary as a handy resource.
