Backhaul using

RouterOS Wireless Networking

Hi

I am going to set up some backhauls 35Mile 50KM. I have some questions, I am hoping I can find an expert here who can help me.

\

  1. I want to have Full Duplexing Connections So I will use Nstream2 .I want this to be a 150MEG through put In Each Direction so can Nstream2 Deal with the 5Ghz 802.11N 40Mhz channel width

  2. When I use Nstrem2 do I have to use to different Antennas/dish …IE: one for TX and One for RX or can I use a Dual polarity dish and just use the one dish.

Here is what i was thinking of Using for each end of the link

The 3 Foot 32DB Laird HDDA5W Dual Polarity version
RB 433AH
Two R52n-m Mini PCI Cards
And a 5 Wattt Amp

Will this achieve what I am looking to do

Thanks in Advance for your time

First advice, TAKE OUT THE 5 WATT AMP, your signal may be good, but your data rates will suffer, due to the noise.

High data rates are VERY picky when any sort of noise is around. I have a 32 mile link using (2) 3-Foot dishes and the signal is -57db, so I think 35 miles will be fine.

Hi

Thanks for the reply


what are you using for radio cards?

My concernt is both link are mouantain top and are often socked in in fact the whole shot is often socked in.

Mountain Top is Mountain Top is the best you can get, I’m not sure what you mean about “Socked In”. I’m using SR71-15 cards.

That is what I was going to use if I didnt use an amp just wasnt sure I would get enough through put I am hopping a 100 meg fibre connection so I woul like to get all of it over the link not just 50 megs or something.

I mean it is in the clouds allot

the 5 watt amp will screw things up for sure

XR5 will do that distance also

I try SR71-15, they can’t give me 150mbps. What RB and ROS version you used? In addition, i have the link 49km with XR5 and i have -59dbm signal, when i change it to SR71-15, ROS show me the -70 only.
