Hello everyone,

I need to build a short (cca 500 meters) Point-to-Point link vith following requirements and conditions:
- speed has to be as high as possible on both parts - wireless and also wired (wired has to be 1Gbps) - 650 Mbps wireless is the preferred minimum, 540 Mbps is the absolute minimum
- installation will be in VERY noisy environment
- use of 5 GHz (there is no possibility to use licensed frequencies, e.g. 6/10/24/60 GHz due to the cost for license)
- power consumption: as low as possible
- cost of the device: as low as possible
- powering: PoE (using RBGPOE)
- definitely NOT sector antena (NOT 90/120 degree beam width)

Optional requirements (would be good to have, but is not critical to have it):
- beam width as low as possible (least critical requirement)
- weight: as low as possible

I have been thinking about following models:
- SXT 5 ac (RBSXTG-5HPacDr2) - can anyone confirm what is noted at mikrotik page: 802.11ac up to 540Mbit? Is there any reason why it is only 540 Mbit/s?
- SXT HG5ac (RBSXTG-5HPacD-HGr2)
- SXTsq 5 ac (RBSXTsqG-5acD)
- LHG 5ac (RBLHGG-5acD)
- DynaDish 5 (RBDynaDishG-5HacDr3)

Which one would you recommend and why?

Thanks in advance for any comments.

650 Mbps wireless is the minimum
- installation will be in VERY noisy environment
- use of 5 GHz

Not possible make this link...

could you please explain why? which parameter is making it not possible?

Use DragonWave products

Use DragonWave products

Could you please stay within the topic name? I am asking for MIKROTIK product recommendation.
If it is not possible to do it with MikroTik, please write WHY it is not possible and what should be possible to get with MikroTik products.

Thank you.

With 802.11ac you will not see this Datarates in noisy environment!

No matter if you buy Mikrotik / UBNT.
Noisy is noisy.


One possibile option is LHG60G, but no one knows when this devices arrives market!

If you need this link yesterday look for Ignite Metrolinq 2.5G

Thanks in advance for any comments.

It is not possible to satisfy this with a single 802.11ac link.

1) The speed of connection is not the effective speed of the link. So, if your device connects at (say) 500 Mb, this isn't the available link bandwidth.
2) 802.11 is half-duplex. If you get (again) 500 Mb, then it is split between upload and download. 100/400, 250/250, 300/200... whatever floats your boat. And this is not the available bandwidth, remember?
3) The fastest Mikrotik 802.11ac product, if I'm not mistaken, would sync (with perfect conditions) at 1300Mbps. The available real bandwidth would be something about... 800Mbps, I guess. Half duplex. 700/100, 200/600, 400/400. At best. And you want at LEAST 540 Mbps.
4) You said this would be in a noisy environment. No way You will be able to get the highest speeds in these conditions.
5) There is a new product (https://mikrotik.com/product/wireless_wire), at 60GHz, that would work for You - but it's maximum range is only 100m. It is planned another version, for longer ranges. But nothing so far.

You can try with https://mikrotik.com/product/sxtsq_5_ac
Maybe link will achieve 300mbps.

Mistry7, Paternot and InoX: thank you guys so much for your help, that are the answers I was waiting for - clearly written and full of facts, much appreciated guys

1) I have to clarify, that 540 Mbps was meant as half duplex, so one problem is solved
2) well, regarding noise, there is nothing I can do about. But when considering your real-life experience, what could be the real available bandwidth? Would it be possible to get at least 100 Mbps fullduplex?
3) As I mentioned earlier, 60 GHz is not allowed for public use in my country, so I have to use just 5 GHz (no way to do it with 2.4 GHz, it is 10x worse with noise than 5 GHz)

Once again, thank you guys

It is not possible make 500Mbit link in noisy environment. As others have said. You'll be glad if you do 100-200Mbps half duplex connection.
SXT is not suitable for a noisy environment. It is completely plastic.
Which frequencies are free (without licence) in your country? 10, 17, 24, 60 or 80Ghz?

Thank you Honzam.
It is available only 2.4 or 5 GHz.
Regarding noise, would DynaDishh be better one for this? Or which one would you recommend for noisy environments?

Which country have only 2,4 and 5Ghz free?
Yes DynaDish is better then SXT. How much do you have interference? How many networks do you see in the scan?

Sorry, I have checked the National Frequency Table and found there is also 24.15 - 24.25 GHz; available and also 61 - 61.5 GHz.
I assume that price for these devices will be much higher than for 2.4/5 GHz, or am I wrong?

Regarding number of WiFi networks, I can see about 25-30 networks on R52 card with 2 dBi omnidirectional antenna

For 24Ghz Mikrotik have any product. For 60Ghz have https://mikrotik.com/product/wireless_wire
but this is only for 100m distance. Price is very good
If you are not in a hurry, wait for LHG60. It is ideal for 500m link with capacity 1Gbit full

1) Well, that's good to know
2) We can't answer that. I've seen places so noisy that one could get more than 30 Mbps. On the other hand, using single chain and 80MHz on a quiet place, I have managed to do 20 megabytes/s sustained, on a single FTP transfer.
3) I saw below that 60GHz is available. If You can wait for the longer range solution, may be worth it. The specs are 980Mbps effective (almost gigabit wire speeds) and full duplex. But You have to wait for it - and we don't have a timeline.
