Multi-Carrier Aggregation in wireless transport

[freeinfo123]

E-band product provided by huawei si better ,at least 4096QAM gives a better speed

[simog72]

unfortunatly 4096QAM from Huawei is only usable with a specific modem card , specific ODU and specific bands and no XPIC

so with too much restrictions (IMHO)

Freeinfo123 do you have additonal info on huawei solution please share

RTN380H eband is nice because offers a 10G connectivity

then
using specific modem card:ISV3
specifi traffic port card : EM6D
and specific 2U high IDU: RTN950A (with specific type of controller)
you can build up a Superdualband


but..seems an expensive and complex setup
IMHO they should extend the feature to 905 pizza box IDU

comments?

What's about attenuation on these Higher frequencies which would use it as an aggregated Band ?

[omid373]

Hi Sonproo,
As you pointed , attenuation on eband is much higher than traditional band which will be integrated in Huawei Super Dual band.In fact maximum length of link used with Eband is about 1.5km keeping link at 32Q.
But key concept on Super Dual Band is mechanism of aggregation between traditional link and Eband. High priority data will be carried by traditional when high BER or some other issue detected on eband.but totally SDB is not good solution for links longer than 2km. Because as an example in our network which is mostly based on MW , we need all planned capacity of the link. So in case of any limitation on SDB we face congestion and complains by subscribers.
E******* also has solution named multi band aggregation using MMU3+traditional ODU aggregated with eband based on same concept.
Finally , In case of having enough spectrum , 112Mhz channels can be good solution which is upcoming in new 2017 products.for example on Huawei XMC3 it is supported in 32g and other bands are in their roadmap.

on that topic ...finally some vendor starting offer this new kind of antenna

Hello,
I am Danny from Siklu and would like let you know that our customers are leveraging our related solution since 2014.
We have a solution page with overview and an application note.
https://www.siklu.com/portfolio-posts/siklu-overbuild/
The linkedIn post contains real customer testimonial https://www.linkedin.com/pulse/siklu...mits-bensimhon
And, I can tell you that ~2 weeks ago another customer deployed it for 22Km.

Thanks,
Danny

Hi Denny welcome in the forum
as I know the Siklu solution is not exactly what we are describing here

Siklu is using two different Radio EBand + Sub6 radio to build up a mixed link (unlicenced - in most of countries)

Here we talk about of an antenna technology able to merge a 10Gbps Eband radio PLUS a Standard freq frequency radio (typically 13 , 15, 23 ,18,32GHz depending on scenario)using a single antenna(HYBRID LINK)..
but also two different standard frequencies radio (15-18 , 18-32GHz depending on scenario) , all licenced. (DUAL BAND)
Typically suppliers use Eband in an HP performance (18-20dBm Ptx) and Lagged @ L1

E*******,HUAWEI, SIAE Microelettronica and NEC talked about this innovative approach @ MWC17(but also before) with different names : hybrid LAG, Super dual band etc etcoffered in split mount but also in a full outdoor architecture.
In few cases some suppliers described also a solution in pure outdoor : single full outdoor (dual carrier F1 + F2) building-up a single ODU dual frequency terminal with one single antenna

in the most of case we are talking about of an antenna technology (probably a feeder technology) and not just a device technology.

Siklu has a pure millimetre portofolio so I suppose could be little more difficult to offer an "optimized solution" like hybrid lag (ex:15 -32GHz or 32 -80GHz)
but you are here in the community now so u can provide a better view on that (if u please)


thanks for ur post

Hi Simon.

Thanks for your welcoming message.
2 points I need to highlight:
> The original Siklu solution is lower frequency (backup) solution band agnostic. Our customers are using it with both 5GHz (in some cases)2016 09 Imperial Hotels London, project by cyberair and UKB.jpg and also with licensed radios at 17/18/23GHz as well.
> Several months before MWC, we delivered a solution with one antenna (80GHz + 5GHz) to specific customers

The solution with 80GHz+18GHz or 80GHz+23GHz antenna came from MTI Wireless Edge (an antenna mnfg) and yes, other vendors showcased it in MWC, but I am not aware of any operational, with a paying end user, implementation to date.

As for high power, L1 solution, Siklu got the EH-5500FD which offers unmatched link budget for single 80GHz radio who delivers 5Gbps full duplex. We do have customers who use it for 10Km and even more with a lower frequency band radio as backup.
The EH-5500FD with its 10G SFP+ port, offers also <10nSec delay

Kind Regards.
Danny

thanks for clarifying,
Can you elaborate on your "with licensed radios at 17/18/23GHz as well"? was this with single antenna? I didn't know siklu had licenced frequency bands, this could be a strong differentiator! Although I guess the picture is not related to this solution, as we see always dual antennas.

Please remember to avoid making "marketing claims" in the forum such as "unmatched link budget" but focusing on technical aspects.
if you want to say what's is the PTX for ETH5500, we can evaluate the "unmatching" performances.

Clearly to deliver 5Gbps capacity you need a 10Gbps port. do you plan to extend to 10Gbps also in the radio as referred in my previous post?
e.g. RTN380H; ALFOplus80HDX; ML6352 just for references.


The solution with 5GHz reported here could be interesting but off topic for this thread. you may open a new thread on this.

Hi Simon,

Siklu is not manufacturing lower frequencies radios, nor antennas. Yes, the solutions I was referring to are "capacity boost" related: those customers usually had in service 17/18/23GHz radios delivering 50-300Mbps at +8Km ranges. The Siklu overbuild solution enabled them to boost the capacity by adding a separate radio with a separate antenna. The integrated L2 switch that comes with any Siklu radio, took care of the networking required to assemble the Overbuild solution with no need for any change at the old lower frequency radio.

EH-5500FD Tx power: up to 18dBm. System gain (without antennas) 71 to 93dBm.

10Gbps solution. Yes, we are going to release such a solution within 2 months.

Kind Regards,
Danny
