Most I have done have been in the -30s or -40s. Need good system margin to keep 99.999% at something near full modulation. Otherwise, you're paying for something you're not using.

Just think of the 4096 as a bonus, it's nice when it's in that nodulation, but realistically any FDD throughout claims in Mbps from a marketing department are closer to fluff than operational reality.

Radio, antenna and band selection as appropriate for the uptime at performance levels required. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP From: "Eric Kuhnke" < [email protected] > To: [email protected] Sent: Friday, April 15, 2016 4:12:31 PM Subject: Re: [AFMUG] AlfoPlus2 Keeping in mind 4096qam requires a really high RSL like -50, so it's better to think of it as a 1024qam radio. Don't engineer link capacity needs based on 80MHz wide 4096... It'll be in 4096 maybe 99.5% of the year. Done right it can be in 1024 at five nines.

Before, SIAE had some very good spec sheets, so ask for them. I also think they can do 4096QAM? 4096 QAM and 112 MHz channels might get you there. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP From: "Peter Kranz" < [email protected] > To: [email protected] Sent: Friday, April 15, 2016 12:47:09 PM Subject: [AFMUG] AlfoPlus2 Has anyone worked with the SIAE AlfoPlus2 yet? They promise “ ALFOplus2 full outdoor solution offers 2Gbps guaranteed throughput, enabling successful launch of LTE, by providing best TCO while boosting capacity and availability of the network.” And “first full outdoor supporting up to two channels at 80/112MHz in single ODU” I can’t quite figure out how they are getting 2 Gbps.. 1x80Mhz Channel at 2048QAM = 623 Mbps in my book 2x80Mhz Channel at 2048QAM = 1245 Mbps So are they really using 4 channels? Channel 1 HxV for 1245 Channel 2 HxV for 1245 Total = 2490 Mbps.. Peter Kranz www.UnwiredLtd.com Desk: 510-868-1614 x100 Mobile: 510-207-0000 [email protected] </blockquote>
