Exalt gets 500 Mbps per carrier on an XPIC system. So 500 Mbps with 256 QAM 8 bits per symbols or 62.5 M baud. That will not fit into a 50 MHz channel.
18 GHz/62.5 M baud = 288 RF carrier cycles per baud. If you put 4096 QAM on that same system: 12 bits per symbol. 41.6 M baud. 432 RF carrier cycles per baud. So more RF to accumulate but more more precision needed. This stuff fascinates me.

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? Where can I find a spec sheet?
