PtP 17GHz with Alcoma MP vs Saf Lumina

RouterOS Wireless Networking
1

I need to use a 17GHz solution for a 12Km link for carry stable 200Mbps FD in 5GHz high noise place.
I can’t decide from ALCOMA or SAF, someone have experience with these brands, all the aspects from radio section to mechanical mounting?

Thanks

At the begining of our wisp structure we can’t decide between SAF and Alcoma like you.Both of them is perfect but we select SAF.It’s very usefull for us especially FODU model.(Full outdoor unit)There is no any IDU equipment at this model.This is perfect for us because we haven’t enough space for IDU.Also the Ligowave is the awesome product http://www.ligowave.com/ligoptp-5-23-unity…

Next week we install them(SAF) to our towers.

Good luck…

Ok thank you, yes also for me at the beginning we needed only 30Mbps but now much more. I plan to use 120cm dish.
Now I wait for some other suggest.

Thanks

I have a price list of both and for same dish diameter there is around 1700€ of difference ( SAF is cheaper)

5

Suggestions?

Thanks

we use many Alcomas and they work great, exactly as fas as Alcoma declares. So if you buy for example MP360 link and Alcoma sais it will bridge 386Mbit , than it will. So this is what i like.

Not like 1,4Gbit Airfiber runnig max 300Mbit duplex or 400Mbit siklu running 150Mbit duplex

You may be interested in this solution: Siae AlfoPlus 17Ghz. It’s much better than Alcoma, because it has QAM1024. As I know it’s also cheaper.

@czolo
Siae AlfoPlus 17Ghz - how much cheaper?

9

Its not cheaper and Alcoma supports

  • Channel bandwidth 3.5 - 112 MHz
  • Modulation scheme QPSK - 1024QAM
  • Transmission capacity up to 920 Mbps full duplex

so why Siae ? and whats the stupid voltmeter ? Alcoma has full management with signal aligment tool.

10

Could it possibly be for measuring POE voltage on load, and comparing the accuracy of management software reading and disconnecting afterwards?

11

hi,

can someone tell me how is this discussion related to Mikrotik??

12

For me the difference in price is about 500Eur.

13

Technically, I see that there is no difference between them. Voltmeter is useful when you setting the antenna on the tower. It’s smaller then a laptop with www managmenet.

14

Where can I buy complete Alcoma link with >400Mbps, for less than 4k Eur?

15

being on Mikrotik forum… can still someone tell me how is this discussion related to Mikrotik??

16

We use mikrotik for all the network but for the main backbone now we can’t use mikrotik and 5GHz we need 200-300MbpsFD. And other wisp have the same problem…

17

can we achieve this 200-300 Mbps FD using Mikrotik Bonding? i mean there has to be some way to this… yes i understand bandwidth will be a issue… but Alcoma and other allied units are highly costly… if similar performance can be delivered using Mikrotik all the way it will surely be the boon for wireless networking…

This cant be done with MT at the moment. You cant get the low latency of a FD Radio and you cant achieve the Bandwidth. Licensed gear works with 256QAM at least. Newer do 1024/2048. Channel size
is up to 2 times 56MHz.
Most WISPs use Licensed gear at the central lines and MT at the smaller links/customer connections and for routing.

so in this i suppose the wireless link is not from Mikrotik?? am i right???

The ping - What distance with the wireless links also what is media converter?
