Wireless sensor networks

Zigbee networks have this wonderful capability to self-heal, which means they +can reorder connections between them if one of them is inoperable. This works +our of the box when you deploy them. But you have to have in mind that achieving +this is not as easy as you would think. None of it is plug&play. So to make +your life a bit easier, here are some pointers which, I hope, will help you.

  • Be careful when you are ordering your equipment abroad. There are many rules +and regulations you need to comply before you get your Xbee radios. What they +do is they wait until you prove that you won’t use the technology for some +kind of evil take over control of the world project :). For this, they have +EAR (Export Administration Regulations) which basically means “This product +may require a license to export from the United States.”.
  • I don’t know if this applies for every country, but when we purchased our Xbee +radios from Mouser, this was mandatory! What we needed to do was to print out +a form and write information about our company and send them a copy via +email. With this document, we proved that we are a legitimate company.
  • When you complete your purchase and send all the documentation, you are not +clear yet. Then customs will take it from there :). There will be some +additional costs. Before purchasing, make sure you have as much information +about costs as possible. Because it can get costly in the end.
  • I suggest you use companies from your country. You can seriously cut your +costs. Here in Slovenia, the best option so far as I know is Farnell. And +based on my personal experience, they rock! All I need to say!
  • Make plans when ordering larger quantities. Do not, I say, do not make your +orders in December! :) Believe me! You will have problems with stock they can +provide for you. So, we were forced to buy some things from Mouser, which was +extremely painful because of all the regulations you need to obey when +importing goods from the USA.
  • Make sure that firmware version on your Xbee radios is exactly the same! Do +not get creative!!! I propose using templates. You can get template by +exporting settings/profile in X-CTU application. Make sure you have enabled +“Upgrade firmware” so you can be sure each radio has the same firmware.
  • And again: make plans! Plan everything! In months advanced! You will thank me +later :)
  • Test, test, test. Wireless networks can be tricky.

If you are serious, I suggest you buy this book, Building Wireless Sensor +Networks. You will get a glimpse of how networks work in lumens terms. It is a +good starting point for everybody who wants to build wireless networks.
