there is several benefit from narrower freq chanell in p2p applications. all together using for example 500mhz it would be possible reach a noticeably longer distance (2500m for example) or more stable connections on lower distance especialy on rain conditions.Of course, all this would mean differen...

vlatko

my 2 cents. i think signal drop is not about rain attenaution at least not on 100m. my opinion is that durring rain rf path enviroment change dynamically, so originated rf, expirience numerous reflections from rain drop and confuse phase array antenna algoritmh.if this is reason that leads us to nex...

vlatko

please give us details about link drop during a rain. Has it preceded degradation or is just link interrupt with the beginning of rain.if the smaller rain interrupts the link to 100 meters it will be great problem. I have already mentioned several times to the mikrotik how to assess the problem if w...

its not 60ghz antenna pigtail, its look like 60ghz radio or downconverter is integrated on back of phased array pcb,
first cable is power source,
pigtail possible have some rf role, downcoverting to lower freq? or connecting to baseband?

vlatko

mikrotik say, antennas in wap60g a phased array beamforming. i understand why is that important in p2mp conecting several wap60 to one from different directions. but i dont understand when we have simple wap60 configuration or two wap60 in p2p how that work, meaning whitch patch antennas corespondin...

vlatko

its ok to mount radio on metal cooling plate, i just say that antenna should be fixed to center of lhg box.

vlatko

i dont want to vacillate,
but watching pictures from the assembly wap60 board inside lhg box although you have very elegantly resolved board mounting,
I dont think you have positioned the antenna exactly in the middle of lhg box as it should be for optimum results
please consider this

vlatko

obviously its possible to replace wap60 board into lhg box relatively easy. Still I am convinced that the lhg mesh reflector isnt best solution for 60ghz wavelenght. i will repeat it again. Probably would be the best to replace somehow wap60 board inside ldf box and then mount ldf60 on any appropria...

vlatko

we cant (without enormous hassle) setup and maintain 60ghz link over more than 500m without rssi signal level.

vlatko

im already writing about this in https://forum.mikrotik.com/viewtopic.php?f=7&t=128251 obviously its possible to mount wap60 board inside lhg housing, i think its possible to mount in ldf housing also, only question is how mehanical fix 60ghz antenna on top of the board before replacing housing....

vlatko

ok, on https://fccid.io/TV7WAPG60AD/Test-Report/RF-Test-Report-3521245 we can see that device has tested on three channels low 58.32GHz middle 60.48GHz and high 62.64GHz, all that channel have 14,9db/km oxygen apsorbtion but for example we have RBLHG-5nD (International) supports 5150MHz-5875MHz rang...

vlatko

in fact it's not that easy at all at 60ghz there are many questions that we do not yet have an answer from the mikrotik in which frequency range their 60ghz ad devices works. is it possible to adjust the frequency, if it is not why? and whether it will be possible? consider next Oxygen Absorption on...

vlatko

Normis, I would ask you for a more detailed answer please? AT first, lhg60 we will be waiting for another 6 months. Second, the wap60g range could be twice of the lhg60 on the 90cm parabola, and especially since its ts is probably have higher tx power than that on the lhg60. The most important is th...

vlatko

The question is whether it is possible to use it as a parabola feed at all, becouse of a nature of antenna inside (Phase array 60° beamforming).
it is very possible that this is why it constantly reports a connected disconnected problem.

vlatko

Also do you have noticed the exact position of the 60ghz antenna inside the device. Its not in the middle of the box, but also shifted to one side for aprox 10-15mm. To get a quality result over the parabola, you need to place the small antenna inside the device precisely at the focal point of the p...

vlatko

very interesting question,what represent 75-85 signal value, dbi or some percent?

vlatko

dont mean on rx/tx signal strenght, agregated troughput is more important than anything else

vlatko

Anyone tested the RBM11G+R11e-5HacD against Netmetal in PMTP on Sector antenna for example. Wouldnt surprise me that solo wifi card working better than the one integrated on the 912 or 922 board.

vlatko

use netmetal in combination with mant30 in slant polarization and you a ok

vlatko

to be honest nv2 really approaching, and become comparable with even cambium in extreamly noisy areas, with still lower troughput but maybe better stability than others. It does not make things better, its not really about quality of nv2 but the circumstances make the others same bad. but of course ...

First of all, note that im not from the US. I took a quick look at the Western New York territory. It seems you have quite complicated terrain topology, mix of hills and forest all over. If the backbone infrastructure is bad, then it may not be surprising that there are no wisp operators in your are...

just change frequency on ap side down to 5400-5600 range and look again

vlatko

I'm interested in nv2 AP sync, but not yet able to test new options Please someone from the microtik to explain in details If at one location we have 4 mikrotrik sectors that are mutually visible in the signal range from for example, -60 to -70dbi. On the site is also present on all channels a distu...

for lhg 60g is all about price. I am surprised that mikrotik selected housing from lhg rather than dynadish.

is there any simple way to use hotspot only for authorize access without one to one nat in 2.9.x mikrotik?
i mean to route original client ip address, without changing source and without manualy define to_address option in ip binding.

thanks, so its managable from winbox console now?

when we can expect drivers from wireless-test in regular distributions?
