passive reflectors

[Chris Hill]

Hi Tim,

Your PCMCIA card can have directivity, without necessarily having gain... as
in "it works OK in that direction, but is worse that way".

Why can't you move the entire access point?  CAT-5 cable is cheap (40c/m),
and you can run up to 100m of the stuff.  By contrast, coax is expensive (c.
$5/m) and lossy.

Regards,


Chris
