Re: A86: Radio Link




Wow, finally someone has the same ideas as me. I think I radio link would be
cool and better than an IR link in a couple of ways. Since the IR link has a
short range and works only by LOS (afaik), a radio link that has a big range
would be extremely cool.. While I know that a radio link with a range of several
miles would be a bit expensive and maybe a bit hard to accomplish, we do not
need this kind of range yet. While a range of 35 miles would be extremely cool,
for now, I think whoever designs and tries to build an radio link should keep
the range roughly enough so the link works fine on a 20 story building. If this
is a bit unrealistic, maybe have the range be large enough so it would work fine
from one end of a college campus to the other. If that is still unrealistic,
then make it work on the size of a high school campus. As a reference,
Motorola's' two way radios have a two mile range (aprox.), so whoever designs
the radio shouldn't try to make it better than that. I know that someone was
working on an RF link a while back, and I posted the url of his project in this
list some months back, so if anyone who has been in this list and still has all
the postings from the list, please try to find the url that I sent. I do not
have the url anymore since I had to reformat my HD not to long ago and I had no
backup copies of anything. In close, if anyone with much electronics experience
is willing to step up and try to do this, I am very sure many would be thankful
to you. This certainly isn't a simple project, but I am sure it can be done.
Maybe someone in this list is in the TI-Hardware list and can ask them if they
know anything about a radio link or a project for one.
