Re: RFID tracking and gumstix

Hi Jon,

in your design, you have to determine, who is movable -- the RFID or the RFID reader?
If the RFID reader is movable, it is a much costlier project, since each moving target
would have to have a gumstix and a RFID reader.  I think it would be much simpler,
to put the RFID tag on the collar, but make it a powered RFID tag, to allow greater range
of detection.  This way, you don't even need a gumstix at all, but can choose a simple
off-the-shelf RFID solution.

Regards, Alex.

We are planning on a semipermanent collar.  Call one for freudian typo.

The apes are our friends, colleagues, and some of the researchers
even consider them our step children.  We would never do anything
that would put the apes in harm's way or cause them discomfort.

As for the mailing list, I was referred to it by an individual at
gumstix who felt that this list would be a good place to start.  It
may be that I am looking at the wrong technology.  I was thinking
that gumstix would be a good low-cost solution for planting very
capable receivers around the campus.  What they are attached to in
terms of actual sensing devices could be debated upon, and I am open
to suggestion if anyone has one.

I will look at the RFID list for any specifics on RFID.  In the
meantime, I do have a question...


Is there anyone working on position aware motes using gumstix?  If
so, would your solution be applicable to tracking apes throughout a
facility?
