<br><font size=2 face="sans-serif">All sounds great! However, do
any of these radios comply to FIPS 140-2 wireless security standards. This
especially important if Ethernet link is directly to an internal network
even with a firewall. May not be important for non-DOI networks but
becoming a hot security topic and requirement for DOI wireless networks,
i.e., "Trusted Internet Connection" (TIC). Last I heard
Afar was working on incorporating these requirements into their radios
and GE-MDS Inet-II radios (http://www.microwavedata.com/Products/FullProductList/iNETII900)
already comply with these AES requirements.</font>

That's a new company to me. Very intriguing products. I could
see <br>
applications for dense arrays or portable reflection arrays. They
<br>
would probably work fine for our application, except for the power <br>
consumption. Our installation is going to require us to use solar
<br>
and batteries at the site end, and at 1A draw, that's a lot. The
<br>
receive end is in a building so that's no problem except for reduced <br>
run time during a power outage (think large earthquake, radio on a <br>
small UPS). That's still the greatest advantage of Freewave radios.<br>
<br>
Thanks for the info.<br>
