Hi I have to realize a PTP link with 2 Dual Polarization Dish with 28dBi gain and RB912 5GHz, now I have to choice the best protocol for this short link (3Km). I need a ping as lowest as possible and a throughput about 100Mbps so I’m undecided between NV2 and Nstreme dual, which one should I choose?
Obviously nv2. Search on my old post for the better configuration example of one ptp nv2.
I searched with nv2 and ptp keywords but I can’t find the posts 
Can you link me discussion?
Thanks a lot.
Thanks, I add you Karma.
Your request for lowest ping - NV2 will not give you that, it will give you higher throughput,
At 3Kms I would use N protocol and 40Mhz channel
Please remember to post here how go! 
So I have to exclude nstreme and choice between 802.11N and NV2?
After 2 Jump (1 ptp nv2 23,5Km + 1 ptp nv2 8Km), 14ms Google.com is too much delay?
With only one jump 2km: 11ms
(I’m on Italy, i have choose Google.com, but Google.it have lower ping delay)
Some posters here have reported difficulties with Nstreme using V6+, a search will give more info.
I answer with my experience and production machine, not virtually or theoretically, or with “I have read…”
In all my production machine I have 6.10,
all my CPE have 5.26 except the newest have 6.7.
User-Manager, PPPoE and DNS have 6.7 (for the bad rewriting of ppp protocol on 6.8+)
The OP requested lowest ping time over a 3Kms distance, fact remains NV2 will not give lowest ping time
fact remains NV2 will not give lowest ping time
For all the CPE or considering only PtP?
Now I made one test, wait please…
Now with Nstreme, i have 16ms delay on Google.com…
Using Nstreme instead NV2 increase latency on MY link.
Strange - some of you replies encourage posters to search or read further which is good, but when you are asked to search you appear not to like such a reply?
I have been on this forum for a considerable time and there a lot of helpful tips and advice given , but as always any advice given should be taken as “…it works for me but not may not work for your configuration…”
To simply dismiss what others say or report is not wise move by anyone?
Nstreme single or dual?
USer can simply test the configuration, “slave” is auto, master must be set or nstreme or nv2, can directly try.
Really my answer to you are birth after your “fact remains”.
The FACT, for me, are live examples, not hypothesis or theory…
Nstreme, without the “2” or dual is Nstreme single.
Also you write about Nstreme (single):
Some posters here have reported difficulties with Nstreme using V6+, a search will give more info.
What module you add to RB912?
It’s impossible use Nstreme dual if you not add another wi-fi module.
I supposed that the dual polarization can suite the n stream dual…
