Thanx, That helps NGL From: Luciano - Computech Tecnologia Sent: Friday, August 09, 2013 2:00 AM To: WISPA General List Subject: Re: [WISPA] 5.8 Separation
NBL andJosh About Antenna Separation we can say something to clarify. Free Space Altenuation 1 Foot = 37,7 dBm (dangerous) 3 Feet = 48,1 dBm (minimum) 5 Feet = 52,3 dBm ( recommended ) Diagonal separation gives you 42% (square root of 2) more isolation ( around plus 3dBm ). Always try to install it as much far as possible. See an old article I wrote it some time ago, I translated to english today and put in feets (here we use meters). Pictures will help. http://lucianofranz.blogspot.com.br/2013/08/uma-boa-instalacao-de-superpops-good.html I hope to be usefull.

How much physical separation should we plan on between the Tranzeo units and the Nanobridges? Thanx NGL If you can read this Thank A Teacher.
