Re: Ubiquiti 24 GHz
keby si pozriete video, ktore dali na stranku, dak je tam vidiet max vykon 40dbm (3m47sek).

nepochopil jsi mne .. dotaz byl "kde jsi cetl" ze ja bych to chtel nasazovat a jeste k tomu na plne gule s vykonem mimo VO ??
Me jen prislo, ze kdyz resis jakou rezervu to ma pri 33 dB vykonu na trase 13 km a jaky je utlum destem.... To je prece obecna bolest vyssich kmitoctu, A za 3000 USD je to hrube nejlevnejsi gigabitove pojitko o kterem vim, byt by to melo chodit na 1 km. No proste Ubiquiti slagrvort "disruptive" je fakt na miste, tvoje komentare jsou toho dobrzm dukazem....

DIsruptive je skutecne namiste
Ale ta 24 bude vostrá

ví někdo reálnou dostupnost v eshopech? asi to bude znít blbě ale tohle je první věc od ubntu na kterou se těšim, která bude mít smysl.

airFiber -Planning to ship in Q2 - Will be available for pre-order on the Ubiquiti website for the first few months, then transition to distributors.
Q: Any plans for licensed products?
A: The airFiber product will probably be taken and developed into other products.

airFiber Q&A
Q: When
A: Ben will be answering this question later.
Q: Channel bandwidth
A: 100MHz wide, but will support two of those in FDD mode.
Q: ESD protection?
A: Built-in surge supression on all ports. Silicon Transient Protectors will support the main GB ethernet port and the management port.
Q: What are the power requirements?
A: PoE 48 volts
Q: How many can be co-located in the US on the same tower?
A: Because of the GPS sync you should be able to co-locate very well. No specifics on the numbers yet.
Q: How much spectrum is available?
A: 200MHz
Q: What is the lowest modulation rate?
A: 250meg/second is the slowest it will go.
Q: How much DC power does it use?
A: Less than 50 watts
Q: Will there be an SDK available for the radio?
A: Unknown at this time.
Q: Keeping spectrum clean was discussed. How are they working with other leaders in the industry to keep the spectrum clean with HDD?
A: This will never be like the 2.4GHz spectrum where someone will be running an omni. These are pencil beams that need to be carefully aimed at each other.
Q: Is it 700mbps in each direction, or 1.4Gbps in both directions?
A: 1.4 is aggregate. It is 700Mbps each way.
Q: What is the beamwidth of the antenna?
A: 2.5 degrees
Q: How does the radio handle rain fade on the longer distances?
A: Mechanisms are in place to control the gain of the overall system, but at very long distances rain fade is going to be an issue.
Q: Is there support for fiber to the radio.
A: At the moment there is no option, but if there is enough interest this is something they may pursure.
Q: Are there different speeds/frequencies/price points to be offered in the future?
A: No.. you can't have one that's cheaper and slower
Q: Has any consieration been put into a 5GHz failover so that when rainfade happens the link doesn't go down.
A: This has come up in conversation at Ubiquiti, but not in this product has it been implimented.
A: The unit, however, will reduce the modulation rate when it rains heavier.
Q: Is this a loss-less sytem?
A: Yes, the system will rate adapt without losing any data.
Q: From a software level, is there IPv6, will this work with AirControl?
A: Yes. The system is airOS based. Exact same feature set.
Q: What is the max high-rain fade link fade type setup?
A: In a high rain-fade area you might lose 4-5dB per KM. When the rain-fade happens, the fade happens only where the heaviest part of the storm is. As the link distance increases the chance of having more rain fade comes up.
Q: What is the constelation level for data transmission?
A: 64 QAM, but 256QAM is coming. Another 33% increase should be expected when this happens. There are 6 levels of modulation stepping.

Info je že UK to má mít 1.5měsíce po US. By mě zajímalo jak se to bude zaměřovat - jestli s tím bude větší drbačka kvůli těm dvěma anténám než by byla normálně 
. A ještě se optám jaké nejdelší spoje v 24GHz s max. 90cm anténama jste u nás viděli či provozujete v našich podmínkách?

Vzal si mi to z huby. Na delsi spoje 10Ghz, na AP 5Ghz, domaci wifi 2.4Ghz a na kratke spoje by se hodilo tohle 24Ghz pojitko.

ano, přesně tak. Takhle se mi to líbí a takhle se to všechno mezi sebou nebude rušit. Ovšem, jestli to bude mít opravdu takhle obrovský výkony, tak se pro změnu budou rušit 24GHz mezi sebou což neni dobrý. Jednoduchý počty, parabola odstíní kolik výkonu a jaký zisky má mimo hlavní lalok? mimo hlavní lalok bude zisk kolik? cca 0dB? Takže dejme tomu 0dB všesměra? a do toho 30dB výkonu? hmm jako už samotný to bude kolem sebe zářit dejme tomu 20dB což je limit na ptp spoji. No už to tak růžově nevypadá že?
Jako jo, proč ne, čtu je blbý tak ať. Alcoma nabízí max "jenom" 380Mbit na pojítko a nejsou schopni rozšířit kanál aby dostali ve 24GHz víc + cena za MP360... jo tak takhle si to asi už nikdo nekoupí.

Fuj, to bude ale hnusný nechat všechny výrobce do 3km tras vyhladovět 
. Tomu se říká nekalej vývoj, EU by to měla zregulovat .

no uprimne bych rekl, ze 24Ghz pojitek nebude nikde moc diky blbym prirodnim podminkam, takze toto od ubnt asi nikoho srat nebude a naopak to muze byt k necemu dobre ...

Na běžnej internet to bude snad dobrý a jestli na tom povalí i IPTV to se teprve uvidí - tam je co vím větší nárok na stabilitu připojení a i pár minut měsíčně už zákoše může rozladit. Takže pro někoho to bude řešení max na kilák a pro někoho i ty 3km či o ždibek víc. Jenže ruku na peněženku, srát to bude ostatní výrobce i tak dost.
