Anybody tested MT-boards/radio+mimo on Airmax sectors?

Is anybody already having experiance in a setup where a MT-rb with ´n´ radio is running on the neet ubnt airmax sector antenna’s to build a full mimo AP-Client network?

Already any experiances with this and ROS5rc1?

Any input appreciated. I am to build a new tower and would like to start with ´mimo´ but haven´t seen very much nice sleeky looking mimo sector antenna’s yet.

Any usefull advices for mimo PtMP hradware setup?

ask to baltics networks they are selling ubiquiti with mikrotik N

Anyone seen European suppliers coming up with similar solution? Baltic Networks are not shipping outside USA it looks to me and for currency reason it would be nice if we have European suppliers could do similar.

not seem to be going very well. MTI Dual pol antennas are mere efficient.

?

and you can not put two antennas with opposite polarizations? vertical and horizontal sectorial?

Hello, off course can you use 2 antennas, if you have the space. I prfer to use Mars antennas with CPR Case on the back and dual polarity.

8

Not sure about that, correct me but if you use the same polarity same frequency (vertical + vertical or horizontal + horizontal) in close proximity then you can have phase cancellation, and maximum happens at 180°?, but not if using horizontal and vertical ?

9

I would say, you are right. 180 degrees hor and ver is the best way aon “long links”.

I would say, you are right. 180 degrees hor and ver is the best way aon “long links”.

Must be a typo, vertical at 0° and 180° is still vertical but inverted and out of phase, horizontal at 90° and 270 is the same?

to say the truth i don’t see any reason to use two single pol antennas, to complex to much space
which one you are using? 25dbi dual pol?

I’ve been helping deploy the Mikrotik / Ubiquiti Combo in both 5 Ghz and 2.4 Ghz.

I’ll show the one of the 5 Ghz setups first. The sector is being used to feed both clients (currently 6) and to backhaul service to PicoPops (currently 2).

On the Tower:

  • RB800 Running RC10 with Firmware 2.30
    Ubiquiti 5Ghz 19 dBi 120 Deg BaseStation Sector
    Ubiquiti SR-71
    Jirous JE-300 Enclosure
    3’ LMR 195 Pigtails feeding the sector

AP is running NV2 and using 20 Mhz Channels

First Client is a PicoPop

It was setup a few weeks ago and there are still a few things to be done (grounding, high capacity backup).

  • RB800 Running RC10 with Firmware 2.30
    Ubiquiti SR-71 for Backhaul using both chains.
    Ubiquiti SR-71 for AP running single chain (HT0).
    Jirous JC-320 20 dBi Dual-Pol Antenna / Enclosure Combo
    12 dBi 5 ghz Omni Vert-Pol

The distance between the AP and picopop is 1.62 Miles (2.61 Km).

Here is what the picopop looks like:

Here is what the box looks like inside:

Here are the results of a test I did this morning.

When doing bandwidth tests from a number of clients at the same time…I’m seeing the potential 60MB of aggregate throughput.

There are currently 8 clients connected to the sector. The furthest out is 7.7 Miles (12.47 Km).

Some other thoughts on this Combo - The relatively low cost of all the components involved has caused a shift in thinking… instead of deploying high powered, high elevation MicroPops with 20-30 customers being served per AP…you can now deploy lower powered higher-throughput “PicoPops” for 10 to 15 customers.

If you have any questions don’t hesitate to ask.

I’ll post the results of a 2 gHz setup next.

Hope that helps.
