Full Duplex PTP over 7 to 14Kms

[n21roadie]

Anybody using Mikrotik full duplex (x4) in PTP links between 7 to 14Kms?
What throughput can be expected ?

[saintofinternet]

no mikrotik products come in full duplex modes as of today.

you need 4 radios cards 2 on each side for full duplex to work.

Or use OSPF and 4 QRT’s for example and base setup on http://wiki.mikrotik.com/wiki/Dual_Setup_with_OSPF.

thank you.

that looks interesting but has anyone deployed it in actual environment?

I have a few sites doing that - for example we use an RB850GX2 at each end and 4 x QRT’s.

Set up two unique /29 subnets for each wireless link and the radio’s as simple bridge (bridge/station-bridge).

Apply the different costs to the RB850 interfaces facing the radios so traffic flows in a clockwise (or CCW) direction and you will see uplink on one segnment and downlink on the other.

Disable one link to prove recovery. This gives full duplex and fail-over should one link fail.

Another way (not personally tried) would be to use bonding and two layer two bridges. This is not strictly full duplex but gives good aggregated bandwidth and failover http://forum.mikrotik.com/t/wireless-bonding-technique/64488/1

I had for 2 years a link with 4xSXT bonded. It worked very well.

90% of our towers uses this method.

Usually we use LigoWave because they are more reliable in high noise environments.

For the other links where there is no interference we use rb912uag-5hpnd and bridge them.

Gets 100Mbps + both ways.

If one link dies ospf takes care of the rest.

I would say it works so well that if you don’t have network monitoring you wont notice when one link goes down

What througput have you there?

Hi,

guys you think interface bonding is better than OSPF full duplex ?? any real experience ?

thanks

[czolo]

In my opinion: ospf is better.

Can I ask the max distance between towers using this method?

could you share your code used for bonding the 4 x SXT please? which device was used to bond them?

[InoX]

I’ve just found my first bonding result. Sadly the tutorial no longer exist. I’ve used 4xSXT and 2xRB750GL.

It was a better choice for me than full duplex.

Hi,

The longest link we have is about 150km.

Using RBNetmetal 5’s and the biggest dishes ubnt makes.

Signal is -57/-55 getting about 40-60Mbps

Not of the physical equipment, but I can share point A and B

I can share a screenshots of the signal and distance
