Nstream via RB433AH and different radio modes.

RouterOS Wireless Networking

Hi.

Is it possable to setup nstream with two RB433AH?
Is it possable to setup nstream with Rx 5Ghz 802.11a @ 5310Mhz and Tx 2.4Ghz 802.11g @ 2432Mhz

You mean is single link or 2 link?

If single link, why not?
If you mean 1 routerboard with 2 Wireless card (per site) and one is on tx by using 5Ghz.., then rx by using 2.4Ghz…

Then you can usin Nstreme dual but make sure the wireless card was support the rang of frequency as what you planned.

Sorry, didn’t get your idea about single link Nstream. I mean tower A recives data from tower B with 5Ghz parabolic dish and send data to tower B with 2.4Ghz grid dish.

Tower A XR5@5310Mhz <------RX------| XR5@5310Mhz Tower B
        SR2@2432Mhz |------TX------> SR2@2432Mhz

ok, here you go…

Thanks, i’ve already read this article. Tommorow will try set it up, after it will post replay with results.

By the way - will nstream work to CPE (RB433 with 2xR52 and one 2.4 flat directional and 5Ghz grid dish) Hi is connected on 2.4Ghz with Tx-69/Rx-72dBm. AP has two omni (5300Mhz and 2427Mhz)

You can do so, but i will advice us not to use the omni antenna but directional since you just point to only 1 direction.

there is another clients connected to these AP’s.

Just a heads up, and I may be wrong.

NStream and Dual Nstream has some issues with ROS v4. That is to say a percentage of people find the links made by Nstream unstable in the extreme and have had to disable the nstream links.

The Dual NStream you are talking about is likely to also break your links with other clients connected to the omni. Again I may be wrong but if you are connecting the Omni’s via NStream you’re only allowing each to independently Tx and Rx. If this occurs you may find that your ‘clients’ are attempting to connect (RX and TX) to an Omni that is set to singularly Tx OR Rx. I suspect that you can’t have a single radio performing Tx for the Nstream link and Rx for ‘other traffic’. I suspect that it’s either totally Tx AND Rx (Not dual Nstream) or totally Tx OR Rx (Dual Nstream but not functional as an AP).

Okey, i read about nstreame and ros 4.3, i already have downgraded boards on both sides. Will see, will this work better then 5Ghz turbo. by the way 24dbi gri dish is enough for 2.2 miles?
