Rory, Sometimes our engineers in Latvia are not the best at communicating expectations. Of course with no fade, our equipment, just like any other manufacturers, will deliver max capacity. The question is one of availability.
We don't engineer three 9's links unless specifically told to, and even then we fight it. We also only engineer links with at least 20dB of fade margin (this is an old school rule of thumb). I've never seen anyone truly happy with anything less than four 9's honestly. Also yes there are a lot of knobs and adjustments you can make to Pathloss (the vendor neutral program we use) and LinkPlanner to get considerably different results. If you want to send me the LinkPlanner file I'm happy to discuss the differences offlist with you between the two calculations and also set the "conditions" of each profile the same to show you what you're getting. *************************************************************************** Daniel White - Managing Director SAF North America LLC Cell: +1 (303) 746-3590 [email protected] Skype: danieldwhite Social: LinkedIn *************************************************************************** > -----Original Message----- > From: Af [mailto:[email protected]] On Behalf Of Rory McCann > Sent: Thursday, June 4, 2015 7:00 AM > To: [email protected] > Subject: [AFMUG] Cambium LinkPlanner and Licensed Frequencies > > Hey guys, > > Running into a strange problem with LinkPlanner.
