Link PTP 130KM helps ...

Hi macdo,

To get 300Mbps wireless link you need to set data rate to “default” or select from 0 to 15. At MCS 12 you only will get 180 Mbps max with a short guard interval.

To get best performance, try to set your wireless link to “nstreme” protocol and to stabilize your link, change frequency in 5 MHz steps up or down to find your “ideal” frequency.

If you want to “legalize” your link, please search your wireless regulatory restrictions for your country and post here, for example here in spain we can use this frequencies:

5180-5320, 5500-5800

Regards.

hello djfrancis really increased the link to 270-300 Mbps as you can see in the image that I attached although I still maintain it in NV2 since doing the test with nstreme did not give good results the link becomes more unstable and passes much less traffic, with all the changes have stabilized more and more and improved the traffic which has allowed me to work but I did not manage to increase the CCQ above 70%, I have the impression that looking for a better channel can improve but I read on the internet and I do not achieve to give a correct interpretation to the reading of the NF in the tool of search of use of the frequency of mikrotik in synthesis I can not interpret when it is good and when it is bad since I understand there is a correlation between the NF and the saturation by noise in the signal , can help me interpret greetings.

on the other hand that another change could be made in search of more stability was attentive … greetings

Hi macdo, a good way to interpretate this values (Frequency Usage and Noise Floor) is this:

  • A lower Noise Floor value are better (-115 is better than -105)
  • A frequency with constant 0% of usage is a good frecuency. When you find a “good frequency”, set your scan-list to scan 40 MHz upper this frequency and below this frequency. For example, if you see that frequency 5220 is good, set your scan-list to 5180-5260 and see if usage changes or not. If there aren’t changes in a 10-20 seconds on this frequency means that are good for use.

To gain stability on your link the first step is find the best frequency and then if you cant mantain max modulation of link (300/300), set your wireless config to use lower modulation (MCS 0-14 or MCS 0-13) to avoid flapping rate.

Regards.

Hello, good afternoon, excuse me for delaying in posting, I was looking for the ideal frequency which as it does not exist in this link jejejejeje. well I found one that gave a moderately good result but the same CCQ% of the RX never increased above 50% then lei and lei and the only possible solution that apparently worked was not to leave the MSC with multiple selections but to thicken one and so I was choosing to see how much I could support the link and in the end I was as shown in the following image

the good CCQ% oscillates between 80 and 98%, the bad the MSC where the link reacted so it was in 3 what allows to spend as maximum 30 MB in the best case .. now what I do not understand is why selected all MSC or at least up to 15 as it would be ideal the link in TX can pass 150MB but in RX it becomes totally crazy and does not raise the CCQ% because it behaves so asymmetrically.

now this link as mentioned at the beginning of the post is echoed with two radios 922 which is not bad for links not greater than 50KM which are the ones that I usually echo that radio recommend me to use in this link that gives me better results ??

a friend who has a cemenjante link tells me to use the airfiber ubiquiti 5X with the 45 ° Slam system … now I wonder there is not a mikrotik team that size for these links that can compete with airfiber ??

Hello DjFrancis seeing me in the situation where I am and looking for references to continue working with mikrotik I would like to use this equipment RB921UAGS-5SHPacD-NM what do you think?
This would be a good option works in AC which would allow me to work on frequencies greater than 40MHZ so dodging a little noise that already exists in those in that band and the other is that it has a bit more power than the RB912 currently in that link of 130KM that is not little …

The other option is to buy the airfiber5X that you think I want some council or yours or someone from the staff I really do not want to throw money in the trash, greetings

hi everybody and nice day

I recommend mpls and vpls over wireless ptp ( netmetal5...for example), specifically if you are working multicast link IPTV. This avoid bottleneck on interface wlan1 ( without mpls and vpls, you will get only 6Mbps :frowning: ) .

Bandwidth---> 90Mbps/90mbps-->TCP---> I Got with this link-----ccq 97%---Rssi -55 dB--rate modulation 580mbps/520mbps
