Re: Racom Ray3

about 4096QAM/2048QAM modulations... is very improbable they can support it also in large channels 56/80/112MHz I m not native in CZ language ..during video they told if 2048QAM/4096QAM is available in all the channels ? they told something about ROADMAP ? ..when Ray3 is commercially available? I mi...

Re: 24GHz Mimosa B24 1Gbs.

thanks PGB and Matess I think it is right ​surprisely I see some limitation on Ceragon IP20C ..but I never had such problem in Ceragon manual they report use of networkprocessor with limit on number of packet . ​ " Integrated Carrier Ethernet Switch Switching capacity: 5Gbps / 3.12Mpps (mega pa...

Re: 24GHz Mimosa B24 1Gbs.

to me it is not clear (and not acceptable) why throughput depends on size of packet transported..
this I see watching this video

Re: 24GHz Mimosa B24 1Gbs.

Thanks I saw datasheet ..but still it is not clarifying about XPIC , MIMO it just clarify that 1.5Gbps is aggregate ..so it is like 650-700 Mbps Full duplex 256QAM applied to 80MHz according to Shannon theorem is about 480Mbps , in case of XPIC you should have about double something do not fit .. do...

Re: 24GHz Mimosa B24 1Gbs.

I dont know this mimosa device ..can I ask information to whom has used?

- declared capacity it is full duplex ? 1gbos up + 1gbps down ?
- MIMO is 4x4mimo or just they use H and V polarizations as XPIC? (as per ubiquity that declare MIMO but it is just XPIC)

Re: Racom Ray3

I will be there for sure I m very curious about the way ​to transport 1Gbps FDD in 56/80MHz channel (XPIC) using 22W only can you share preliminary about Power amplifier output ? (PTX) ​ "Zveme Vás na uvedení třetí generace mikrovlnného spoje RAy na český trh, které proběhne 28.6.2018 na konfer...

Re: Racom Ray3

midnight_man píše::D :D ale aby ta RAY3 nebola nakoniec 500mb a vybavené.

probably it use a 2048QAM modulator applied to 56/60MHz channels
..and price of course it is important .. right performance for right market ..for right price..Depends
If you have datasheet pelase share

Re: Racom Ray3

my contribution ALFOplus2 has most of frequencies available with 110MHz/112MHz and 4096QAM (@18GHz ETSI permit for 110MHz, in 23GHz ETSi permit 120MHz) CERAGON new Full outdoor (IP20C evolution - RFU-D) will support 112MHz channels too (4Q this year) Huawei RTN320 and NEC IX too but little more comp...
