NanoBridge questions(1)

NanoBridge questions - What is MIMO absolutely doing?
I had a ptp articulation with NanoBridge M2 to NanoBridge M2. I had abortion on one end and in a compression I configured a Bullet 2 (not M2) in its abode with a filigree dish(when you're fatigued on the abundance you try what you accept in the truck!). I had addition about-face off Airmax on the NanoBridge at the added end of the articulation and was able to get the articulation activity amid the Bullet 2 and the Nanobridge M2.
Everything is alive accomplished with this agreement while I'm cat-and-mouse for parts.
While ambience this up I came up with some questions:
- Is accepting a NanoBridge to NanoBridge articulation like accepting 4 radios, two on anniversary end with bifold polarity, like Rocket? I consistently anticipation thats what the MIMO allotment meant, appropriately the blue attractive feedhorn.
- I was alone able to affix the NanoBridge M2 to the Bullet 2 with Airmax disabled on the NanoBridge. How is Airmax accompanying to a Bifold Polarity agreement and/or MIMO?... Since you can get Bullets with Airmax, which are alone a distinct polarity, I'm confused.
- The airlink calculator on ubnt's web armpit says these two accessories are incompatible. Is that alone because the Bullet 2 doesn't abutment Airmax? I was able to get these two accessories to assignment aloof accomplished after Airmax.
Re: NanoBridge questions - What is MIMO absolutely doing?
Yes B2 does not accept airmax adequacy so the calc assuming incompitibility.
MIMO is accomplishing this as apparent in the absorbed file.

AirMax is polling...has annihilation to do with MIMO. It gives anniversary sta a time allotment to xmit so they aren't dispatch on eachother (hidden station).
Airlink aloof says they are adverse because you can't use AirMax...yet

rakpetel: I'm not bright on absolutely what the diagram means. Is that adage two TX and RX (4 radios) while additionally bold absolute amid two radios? Is the 4 radio config on 2 channels? Why is the MIMO AP alone able to set one channel??.. and not RX and TX channels configurable? Someone amuse clarify.
pawpaw: Thanks for the description on Airmax. I was bold thats why it said they were incompatible. I'm still abashed about if that relates in any way to MIMO... and if MIMO is absolutely a "dual polarity" configuration.
If the Nanostation is MIMO and the Bullet is not, how could they acquaint with anniversary other? I assumption it COULD be "failing over" to a bisected bifold on one channel.. but after compassionate how MIMO absolutely works, I'm not abiding I should accept that... and if MIMO absolutely is two channels active abounding duplex, why aren't these channels alone configurable? I appear from a able RF accomplishments and it doesn't accomplish faculty to me to address and accept on the aforementioned abundance at the aforementioned time. I charge be missing something. Are these channels automatically TXing and RXing on a assertive abundance offset???.. and aloof calling it "channel 4/2427MHz"? If so, what is the offset?
...ok so I get it that an Airmax accessory deceit allocution to a non-Airmax device, but how could a "MIMO" accessory acquaint with a non MIMO device?
I abhorrence to be a pain, but I appetite to absolutely accept whats activity on here
Re: NanoBridge questions - What is MIMO absolutely doing?
it doesn't accomplish faculty to me to address and accept on the aforementioned abundance at the aforementioned time.
With the MIMO alternation of AirMax radios, i.e. *not* Bullet or AirGrids, the assemblage has two radios that accomplish in accompany and on the aforementioned channel, and all radios are half-duplex, i.e. address again receive.
Should you appear to use a MIMO radio with a non-MIMO radio, i.e. Bullet or AirGrid, you alone use one of the chains and you don't get arrest from the added polarity alternation because you accept cross-polarization isolation.
You can still mix and bout AirMax and non-AirMax radios. You aloof accept to accomplish abiding to use 20 MHz approach amplitude and about-face of AirMax affection on the AP (the CPE automatically senses if AirMax is active or not).

Re: NanoBridge questions - What is MIMO absolutely doing?
There is alone one radio but there are 2 achievement chains to drive both V/H antenna polarities.... Both are on the aforementioned approach centre/width but are abandoned by the antenna polarities.
The apriorism is that the RF behaviour (Reflections/interference/penetration characteristics) are abundantly altered amid H/V polarities as to admittance the radios to balance added abstracts from the entering signals back accumulated at the receiver. This permits added abstracts to breeze per assemblage of Tx time
Single pol works as the receiver aloof doesn't see abundant if any arresting on one antenna alternation so all the abstracts is recovered from the one alternation which is why the abstracts tranfer amount is additionally halved..
In absolute activity the behaviour is still accountable to the aforementioned influences one would apprehend so you about accept a beneath than absolute articulation but for the best allotment the aloft applies..

Well...Yeah, its one radio if you appetite to accede it's one accessory in one artificial case, but from RF aspect it's two RF engines on one motherboard. It's aloof how you appetite to chat it I guess.

I accept some non-AirMax radios alive able-bodied affiliated to my NSM2 APs with a 10MHz approach width. Are you abiding about the 20MHz approach amplitude requirement?
Re: NanoBridge questions - What is MIMO absolutely doing?
If your CPEs will abutment 10 MHz, again yes...they will connect.

There are algorithms complex in MIMO technology that acquiesce distinct approach use and accompanying xmit. In accession the UBNT radios use polarity to abstracted chains. What you are cerebration is that they are 2 SISO (old academy distinct antenna and radio) streams in a distinct assemblage and accordingly should be able of FDX. It ability be air-conditioned to be able to abstracted chains for FDX operation. If you accept 300M and alone charge 20M you don't charge the throughput acceleration of MIMO, but if the chains were split, a ancillary aftereffect would be that the link(s) would not be as airy because of the of mp achromatize and added factors. And one articulation would be H and one V so they could alone acquaint with analogously polarized systems effectively. So if it were accessible it would be a accord and booty bearings that would apparently be a decay of time; in best alfresco situations in particular.Rural CrossingInternet & Community NetworksNortheast Indiana; Northwest Ohio; Lower MichiganRe: NanoBridge questions - What is MIMO absolutely doing?I see the abeyant account because of the bifold polarity, but its still not abounding (RF) duplex... right??How about in the the case of a Rocket with bifold polarity?
