<BODY bgColor=#ffffff>> This may not be quite true, if the card's RX is poor
then the<BR>> additional TX isn't of much use, as it will send much
further<BR>> (reducing reuse) while being able to "hear" much shorter
distances...
<DIV> </DIV>
<DIV>Sure, but if you use 2 of these cards @ 200mW they can "PUSH" the signal
further hence they don't need as much receive sens ? which would make them even
better than say 2 cisco cards :)</DIV>
<DIV> </DIV>
<DIV>> Using higher gain antenna with lower output card on the client side
of<BR>> things is a much more efficient way to use the spectrum... For
example<BR>> of this see Tony Langdon's post on the 20th of June, about
the<BR>> benefits in using less output with higher gain antenna...
higher<BR>> output could effectively limit your useable signal...</DIV>
<DIV> </DIV>
<DIV>Fair enough i understand how a antenna with gain works both ways, helps
pick up a weaker signal etc... but hadn't heard about the higher output
could limit the useable signal....</DIV>
<DIV> </DIV>> Even a 15dBm card with an 8dBi omni is capable of usable
signal at<BR>> 20km or further, by using a high gain antenna at the client
end, such<BR>> as a 24dBi galaxy... even just using a cantenna the range is
capable<BR>> of being 10km or further... and 2 24dBi dishes have the ability
to do<BR>> 100km on a 15dBm cards...<BR>
<DIV> </DIV>
<DIV>wow, hadn't heard anyone peel figures like this before, enterasys card,
8dBi omni with a cantenna reaching 10k's, nice, good to know, taa</DIV>
