Will canopy NOT interfere with all of the other systems in the area? Canopy works well, but it's not always the solution. What I need to find are wifi radios that have good rx and tx properties. I also need to find some better hpol sectors. marlon ----- Original Message ----- From: "Gino Villarini" <[EMAIL PROTECTED]> To: "WISPA General List" <wireless@wispa.org> Sent: Thursday, July 26, 2007 3:17 AM Subject: RE: [WISPA] self inflicted interference What you need is Canopy Gino A.

Using my laptop at the tower things always work as expected. Just when the customers are further away (lower signal levels) causes the problems. I've moved things further apart and the system is running better than it ever has. But it should still be better...... What I need are better radios. Something with better oob tx and rx stats. marlon ----- Original Message ----- From: "D.
