According to something I read, square is more noise resistant. From: Ken Hohhof Sent: Thursday, May 19, 2016 6:23 PM To: af@afmug.com Subject: Re: [AFMUG] Trango
Do all these manufacturers really still use square constellations? I thought when you were trying to eek out every last dB of performance, you pruned a larger constellation to get a hexagon or something close to a circle.

I wonder what the symbol rate is.

Probably the only way to find out availability of 6/11/18/23 GHz is to call them, then apply some Kentucky windage. I think they are using some new chipset from Broadcom that goes up to 4096QAM? More QAMs, as George would say. Also supposed to be high xmt power without consuming a ton of power, due to xmt predistortion, if I remember right from the WISPA show. -----Original Message----- From: Dan Petermann Sent: Thursday, May 19, 2016 9:44 AM To: af@afmug.com Subject: [AFMUG] Trango Does anyone know when the Trango next gen radios are going to hit the market?
