Some testing here indicates that two-way time-of-flight measurement won't work with XBees. I suspect it has a lot to do with:

  • The frequency band is used by a lot of other devices, requiring non-deterministic noise "abatement".
  • The way the XBee's radios seem to work doesn't lend themselves to time-of-flight measurement.
  • A few other factors that I'm not sure about.

I've gotten the "pingtags" application coded and working. But now I have to build out more hardware for a better test. This means eartags and more base stations (anchors). What people won't be seeing is all the software I had to write to figure out the Beaglebone Black, GPS and XBee's. But I hope most of that is now past.

Is to have several road maps with respect to where the reader is coming from... For example, a person looking for technology would be interested in welding, crop practices, livestock practices, ... But a person looking for a community with which to share ideas would be interested in forums, people (usually in a geographical area), ... I'm proposing different "road maps" to the site for people with different "origins of thought". This lets us address multiple demographics/interests with the same content. In IT parlance, we're just adding indexes to existing content. Also, let the author/reviewer of the content decide which category their content should belong in.
