10 GHz pásmo (Původně: Ubiquiti PowerBridge 10GHz ...)

[ppp76]

Tak kdyz koupis plysovou hracku v polsku a tam se smi prodavat ale v cr se jeste neprodal ani kus tak ji cou tezko u nas zakaze prodavat kdyz se to u nas offico nikdo nedovezl ale pokdu ji koupsi u nas tak ji u nas pak muze zakazat, polakum do teho nase coi kecat nemuze ... do soli si taky kecat nenechaj

[blax]

nemusis, ale ja to v CR koupil .. takze v klidu, uz se tim spojem zabyvaji lide co z toho udelaji platne merici protokoly

platne merici protokoly ty to nechavas merit v akreditovane laboratori? Testcom?

[Viktor Novotný]

to ppp76 ale ano ja to koupil u nas v CR

blax presne tak

[ppp76]

nejdrive merici protokoly, pak na COI at nemam hole ruce

To nevadí ČOI si to stejně přeměří a stačí když budeš mít hole v ruce .

Jasne ze premeri al enejdriv musi dostat podnet s nejakym merenim , nemuzes tam prijit tohle s emi nelibi merte ....

Jo tak tomu rikam hrat prvni ligu , proti mereni testcomu neni odvolani

officalne to prodava nekolik shopu v CR a dokonce k tomu vystavuje faktury, takze lavina byla spustena nebo na co jeste cekat na dalsi zavoz 10.5 nebo dalsi 20.6?

[Viktor Novotný]

necekame ted defakto na nic .. jen na to premereni

[ppp76]

necekame ted defakto na nic .. jen na to premereni

predbeznej termin vysledku je nejakej , ja abych sem enelezl zbytecne hladove kazdej den a lezl az bude neco finalniho

[Viktor Novotný]

zatim presne nevim, ale uprimne bych rad kdyby bylo nejake info cca do patka pristiho aby se to mohlo zverejnit na konferenci v Prerove

[blax]

to ppp76 ale ano ja to koupil u nas v CR

blax presne tak

mereni trva mesice navic stoji poradnej ranec, takze delas sbirku?

[Viktor Novotný]

nemusim, stoji za tim silnejsi hrac

[Viktor Novotný]

ne ne klidek ... penize nereste ...

jinak jen pro kontinualni provoz ... zmenil se me nick kvuli moderovani, ale porad jsem to ja Dade_Marfi

Prej compliance..

Hi,
This is not correct.

We have a Notified Body Opinion, all tests and reports have been completed prior to shipping. We have done everything required from a compliance/regulatory standpoint.

If anyone has any questions, please email compliance@ubnt.com.

Thanks,
Matt

komu: compliance
Dear UBNT team,

I received this email address from Mr. Derby, ACB Europe to find out your plans according to introduction of PCB10 device on Czech market.
I advance let me introduce you my self. I am head of KPE company CZ. I am not sure what rumors are going inside UBNT company, but we are your direct competitor on market of 10+ GHz radios. We do the exactly the same stuff you do, and if I would be that unfair I can clearly say, I am the Godfather of your PBM10, because we already invented, sold and distributed FDD OFDM radios on 10GHz from 2008.
In history you will find I contacted your company about such project cooperation several times with a bid for cooperation, and I was the man who poked Mr. Sedlak in 2007 about possibility of such project. Unfortunately you did not found this useful.

Anyway, what is my story:
I do produce and develop PDH, FDD, TDD radios in CZ, we do custom development and I am active member of local WISP community - once I co-own one WISP, then I am in broad contact with other ISP during meetings, fairs etc..
I have no idea, what is your information about non harmonized band in CZ, But let me introduce:
The band is up to today used from 100percent by FDD system- it is not written - but rule. It means 1 sub band for RX, one for TX with minimal gap of 56MHz between RX and TX. This way we are bringing 180Mbit full duplex in 1 chain from one side to another with sensitivity of -71dBm and 28MHz channel.

By introducing your device to the market, from Statement of Opinion by ACB, your is TDD. If you are friendly with knowledge of problematics, you will find that TDD radios are not RF compatible to FDD if used in RX subband and it will interfere FDD, because of its high peaks on neighbor channels (it is just FFT mod. issue, SAW is not the saver), in opposite the FDD Class 6 radio which normally sold in CZ. FDD radio will not by their mask interfere with RX of PBM10, because of very steep loss of energy on border of channel approx 50dB in 2,5 MHz, and all neighboring devices will be fine with ACDP regime.
Second what I found is: Your specification is Class 2, which is in direct contradiction of used Atheros RF chipset which uses 2x64QAM OFDM. If you will read thru the ETSI EN 302 217 2-2, you will find your device has to be tested at least by class 5A which means capacity of 2xATM (155Mbit) and much more agressive mask, which you be not able to get with same baud speed. I hope my words will help you imagine what I am fighting against. It is not beacuse we product PDH radios.. It is because we want the market grow the same power as last 5 years did, thanks to hi speed 10GHz band.
HONESTLY, WE CAN INSTANTLY START TO PRODUCT COMPETING PRODUCT ON MIKROTIK . With real truput of 158Mbit of NET trhuput in both chains and 28MHz channel and gigabit port, but this is not the goal. Believe me. The best competition is to cooperate.



Where I am aiming: As we already in 2005 had idea of entering market with transversed WI-FI, we found that idea faulty, because it does not respect used rules and parametrics of local band. Go ahead with such product to Slovakia, Croatia, Serbia, Monte Negros or Dalmatia, where the band is virgion, ut please: DO NOT KILL THE BAND IN CZ WITH SUCH LEVEL PRODUCT.
Why we did not entered market?

The aim it self: These days are serving CZ market over 10 000 units of all models from 2002 to 2012 with net thruput of 30 - 200Mbit FDX FDD, without coordination in full power of its abilities. 60+ by one site, with no interference each to other (oh, yes really, duplex 4 channel 2 polarisation!). By introducing device you will choke your now days customers, because they will loose their heavy backhaul solution which are feeding your low end APs, they have not to pay licenses now, they have spare money in oppositon to large operators to invest new hotspots quickly, without large investitions and mandatorry annual fees for lic.. Count average operator in CZ own 3-5 links.. Licence fees now: 0, next year 3-10 000USD. The now days 10GHz is rock stable, solid T bone of CZ WISP.

What than if you come??
They will have to buy devices (each by 7-12K USD) in licensed bands to withstand the loss of their back haul solution, which are the same reliability, almost the same thruput, but 1,5 expensive now days PDH on 10GHz and license charges, price of license will grow up shortly as demand will grow up dramatically. The now day cost of PDH device is approx 5000USD per link with net thruput 180Mbit 1 polarization, 28MHz.
Regulator against ISM band are able to sell only limited ammount of licences of cheap licences (they are now days already sold out). There are not free licences for next 10 000 radios in CZ. Licence per link from 13-36GHz costs average about 800-2000USD per year. So do the math and try to find out, why the CZ market rockets this much. Because of existance of PDH on 10GHz, they can make more hotspots to be fed by 200Mbit traffic, they can boost the growth with no payment of license.

Do you understand that? The demand of new HW will crash instantly, because the WISP will have no more reliable band to bring datas over 3 km and will have to rearm quite quickly. This is why we did not entered this market, the unit we had ready in drawer in 2005.
This is it, please consider to contact me, if you will like some clears up. The weapons are still hot, not because of loosing market of 10GHz, I am still in game, and other producers are happy to sell licensed bands already, but because you will poison the customer, h¨which buying power will be immediately transversed toward licensed solution.


There are few thing, you can do about it technically.. It was my public proposal to Mr Perra, when he was in Prague few years ago. We you figure out what you are doing, let me know. We can realy help you globally.

With best regard Michal Peterka, KPE spol. s r.o

P.S. Sorry not to come Chicago, but I found lately my passport was expired this time unfortunately.

zarizeni mam i s fakturou - uz nemame hranice, takze je uplne jedno jestli to koupim v CR nebo EU nebo snad ne?
je CR v EU nebo NENI?
co ma COI resit - ze jsem si koupil zarizeni s platnou certifikaci, aha ona platna neni tak at si to COI vyzada od vyrobce a pak vyrobek zakaze, ale prijde mi nesmysl,ze to musim koupit v CR aby COI jednala.

Kdyz pominu vetsinu balastu, tak ti jen reknu ze ano - mame spolecny trh. A ne, nemuzes si vsude poustet co nekde jinde nakoupis.
Zkus si tady koupit libovolnou 2,4 wifinu outdoor, rekneme Nanostation, a vyraz do Francie. Uvidime co ti reknou, az to tam pustis.
Tys nevedel, ze ve Francii maji 2,4 povolenou pouze a vyhradne indoor?
