all your licensed links should be engineered for -50 or lower

Well yeah, I guess that's what I was trying to say. 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.On Apr 15, 2016 2:15 PM, "Mike Hammett" <[email protected]>

I can take a 4096 radio, add engineering and come up with a 1024 performing
radio (or a 4096 performing radio). I can't turn a 1024 radio into a 4096
radio. Radio, antenna and band selection as appropriate for the uptime at
performance levels required.

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.On Apr 15,

Well, what do they get at a 112 MHz channel instead of an 80 MHz channel?
Europe has 112 MHz channels available now. 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.

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..
