Tom

it's in the pipeline, stay tuned to our SM channels - we'll announce it there once it's up. Datasheet itself is not enough unfortunately..

Hello, we'll be at the WISPA palooza in the US, you can get a free shirt there. We are also setting up a swag shop where everyone will be able to purchase them, thank you for patience.

Hello Chris, we are in the process of setting up a swag shop, so until then, we stop mailing T's one by one. Hang on there, and follow our SM channels - once it's out, you'll know it..

Hey Keith, actually, that is exactly what is in the works, you'll know when it's out from our SM channels

just PM'd you

Hi, the recommended spacing is 1 m. However many space the antennas much closer than that and their results are still excellent.

Hi Sarv, we do not make any antennas for wifi routers, unfortunately. But if you have the N-connector output from those, and they work in the same spectrum, you could try any of our Carrier class or TwistPort antennas depending on the link budget. For the Twistport ones you'd need TPA-SMA adaptor and corresponding cable though. Would be interesting to know if / how it worked. If you end up trying, please write here how it went.

Hi Ajm, thanks for the feedback, we have bunch of updates in the pipeline that might include the export of the device locations. We'll look into exporting the heat maps as well. You'll know when it's out from our newsletter / social media updates..

thanks for the tips, we'll look into it

Seems like the link you shared is broken As RF elements, an antenna manufacturer, we can tell with certainty how our antennas work and what they do. Since this particular MU-MIMO implementation is a feature of the radio, in-depth questions should be directed to the radio manufacturer.

Hi And, the circle section on the images you shared indicates the -6 dB beam width of an antenna. The beam width is not equivalent of RF coverage given antenna provides. We are absolutely clear and vocal about it, for example in our Sector coverage uncovered webinar, which explains it all. This is not to create confusion, quite the contrary - clarity. We do our best to help users understand the difference between antenna beam width and coverage. So we give people tools and information useful for their practical life. More over, this information is valid for any antenna out there - the beam width does not mean coverage. We say how things really are, instead of trying to sugar coat our messages by for example saying 'this antenna does not radiate outside the 60 deg angle'. The rest is of course up to the user to test what works in real life and how. Our horns do not have any side lobes. Any antenna engineer understands that despite every antenna radiates in every direction, it is only a question of how much is too much. Therefore, for all practical considerations of WISP networks, our horns do not have side lobes.

Thanks for the tips, we'll look into it in our future updates

That is interesting, and how exactly do those WISPs identify that the radio works in MU-MIMO besides the grouping of the CPEs? Regarding the bracket suggestion, maybe in the future we'll make what you suggest, thanks for the tip..

BE is important for both AP and CPE, but more so for AP (from the angle of a network as a whole), since AP is the device to which all the CPEs are connected. So if the AP radio is seeing a lot of noise, all CPEs suffer. Where as if only one CPE sees noise, it's only that one user that sees the effect.. In my opinion BE says much more about colocation capability than FTB ratio - one side lobe (back lobe) simply cannot be more important than all the other side lobes combined.

ok, so we synthesized the real install for you check out the photos :)

Unfortunately we don't have many photos of the AS-5-20 with this radio, why are you so keen on seeing real life picture? We could print it out here and test it if you want, but it's a simple plastic part and our designers have tested it long time ago

I don't know do we have a real install photo of this setup but if you search facebook WISP channels, maybe you'll get lucky

Yes, the ePMP 3000 MU-MIMO works if the antennas have horizontal spacing, without it, it won't work. They can be somewhat vertically spaced, but the horizontal spacing or lack there of makes it or brakes it. It has to do with the radiation pattern of the array - if the antennas are above each other the coverage of the array looks almost identical as if you used just one antenna (except the further reach because of the array effect). Once the antennas are horizontally spaced, the coverage you see shows minima and maxima depending on the antenna spacing, that result in the possibility of 'spatial filtering' and polarization division into 2 user groups and therefore MU-MIMO. In the near future we will release a video about this, so stay tuned to our YT channel and SM outlets..

Right, the higher FtB ratio the less noise. But, FtB ratio quantifies only the backlobe - one side lobe out of many antennas used in WISP industry typically have and all that at one frequency and from a single polar plot.. What about the rest of the radiation pattern? The rest of the sidelobes are much substantial than just backlobe by itself. This is exactly why FtB ratio is practically useless (in other words useful in very few instances). We believe Beam Efficiency (BE) is way more comprehensive and reliable measure of noise suppression capability of antennas. More over, we extended its definition to an average number over the whole antenna bandwidth and both polarizations, which makes it super robust noise suppression measure. BE is great because it gives you a simple numerical value from 0 to 100%. The higher the BE is the better an antenna suppresses noise - check the BE of the most common antenna types here.. We also have a full webinar on BE if you want deeper explanation and have a little time - here.. What do you think about BE vs FtB?

The Symmetrical horns do have corrugations inside, from the Asymmetrical ones only the 30 degree one does, the 60 and 90 do not. How much FtB ratio is enough? And why do you think it is important?

🤐

Hi And, no speculations here. What Dmitry says is true - the MU-MIMO will not work with horns attached to THB. However, you can use the radio with THB in the 4x4 MIMO no problem.

We design many antennas all the time, so it's hard to remember
