Wireless Wire (RBwAPG-60ad) minimum distance

I am looking to use the Wireless Wire kit to bridge two buildings that are separated by a railroad track. This distance between the buildings is only 45 meters but the railroad right of way prevents easily running fiber between the two structures.

Is this distance too close to work? Will I need to reduce the power on the units?

Thanks!

I guess the distance is perfect.

Minimum distance is less than 1 meter. They work excellent from 1-150 meters, for longer distances speed will be lower. Your distance is perfect for ~Gigabit link.

Normis link avalibility at 150m?

Thank You Giuseppe

Hi normis. Sory bad english.
last day install wap60 link 1.1 km. Distance.
i install Wap60 mount (home made) 45 cm parabolic dish antenna.
My signal wap60 device minimum 75 maksimum 85.
but not connected. wap60 Status connect and notconnect, connect and notconnect
continuous.
What problem. ? Wap60 software distance limitation or ack timing problem ?

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

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 parabola.

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.

wap60 device wireless status screen signal level 0 to 100

yes. wap60 device antenna location modified. i transport antenna middle of the box and good focal point.

I think LHG60 is not a different design.

Distance away, reduce distance due to antenna gain.

1.1 km? The device is advertised for 100 meters. You should wait for LHG 60G instead.

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 that wap60g will be easily to import as an indoor device, and lhg60 will probably be problematic because it is for fixed outdoor.
so please mikrotik for meaningful answer, is possible to use wap60g to feed parabolic antenna.

The wAP60 has a new type of beamforming antenna that adjusts it's beam based on conditions. It may not work with dishes like that. It is not officially supported and I can't give you any advice on that.

Normis, I want to use RBwAPG-60ad for distance 150 meters. What real speed will I get? 1Gbit/s or not?

And 1.1km with 60Ghz would be to much. This is like shooting 5GHz through trees. You need luck and good weather. This is due to physics and no 60Ghz gear I know gives good/reliable results at this distance.

the further the distance, the lower the frequency. Why do you think you can reach thousands of kilometres by using low frequency (long wave)?

Short distance: 60 GHz
Long distance: lower frequency.

Do not complain about speed. That is all depending on environment, weather, luck etc.... Today you reach 500 Mbps... tomorrow 900 Mbps, and in the weekend 20 Mbps..... Go ahead, and explain to the clients (when they complain about speed), that today it is rainy, and the connection is not stable....

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 57.3GHz-62.3GHz 11dB/km
Oxygen Absorption on 58.3GHz-62.3GHz 14dB/km
Oxygen Absorption on 62.3GHz-63.3GHz 11dB/km
Oxygen Absorption on 63.3GHz-65.2GHz dropping all way down to from 10db/km to 4dB/km
as you can see if the device can be set to 65175Mhz (65.175GHz) where only 4db/km oxygen attenuation
on the 90cm or 120cm parabolla dish, can be reached up to 8km with a signal below -60dbi
you have to admit that this drastically changes things,
of course, the question is both the legality and the stability of such a link.
taking into account the sensitivity to weather changing, rain and fog, this range is probably smaller,
but some 2-4km are also a big difference compared to the announced upto 1km lhg60.

ok, on https://fccid.io/TV7WAPG60AD/Test-Repor ... rt-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 range but we can set on superchannel from 4920MHz up to 6100MHz
is it possible to have superchannel on wap60g, how and in what frequency range?
on middle channel with 90cm parabola calculation give us -55dBi on 2000m with good margin for average rain and fog conditions.
