Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Increasing Wi-Fi SNR with NLoS

How can I figure out what type of antenna (e.g.
omni, Yagi, parabolic, etc) I should use to increase
my SNR to an 802.11n router signal to which I do
not have line of sight? A straight line running
between the antennas would run through approximately
30 m of interior construction. With a 1 dBi antenna
the noise is at about -92 dB while the signal can
range between -70 dB down to -90 dB and the link
is frequently lost. How can I figure out how much
gain on my antenna would be appropriate, 6 dBi,
12 dBi, 15 dBi, and what pattern would be appropriate?
I’m an EE but I have no RF experience and I'm
looking to learn more about how to make such decisions.
I would greatly appreciate your advice or
any references or tutorials you can point me to.
