Re: [AFMUG] Small site Gig POE

I asked a similar question recently. Netonix + MikroTik hEX seemed to be the most suitable answer. I'm waiting for the WS-8-150 versions, though. Also, it seems MikroTik is working on a Gig + SFP + PoE router similar to the 750UP. I'm looking forward to that too. On Tue, May 17, 2016 at 8:51

But the max power is a circle (in I-Q plane) set by either regulations or power amp. And best noise performance is achieved by maximizing vector distance between constellation points. So a square should be sub optimum. From: Chuck McCown Sent: Thursday, May 19, 2016 7:45 PM To:

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. From: Chuck McCown Sent: Thursday, May 19, 2016 5:26 PM To:

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

Speed tests try to determine the characteristics of the last mile connection, using some assumption about what happens when you reach its capacity, like increased queuing delay or increased packet loss. They probably work better when there is a physical limit like DSL line rate. Speed tiers
