Re: rb433ah interference between mpci cards

Well at least we are getting somewhere. Maybe there is a problem when 2 of MT designed cards are connected on the same backplane. Interesting that a Ubiquity mixed with an MT does not give issues. That is the first comment I have heard so far relating to mixed manufacturers on same backplane. But I...

Re: rb433ah interference between mpci cards

Side by side comparision. I didn't have a RB600 laying around at the moment so i just put two RB433/333 beside each other and did the test again. Bleed over was almost completely gone. Very minimal bleed over at 25db power. If i dropped back to 20db power it was gone compleatly.

Re: rb433ah interference between mpci cards

Now this is 10mhz channels. Now we are able to put two cards on top of each other with full power and not bleed over too much. You could run 3 non overlapping channels at full power 25db or use all 5 if you are running a lower power setting such as 15db.

Re: rb433ah interference between mpci cards

Tests below are all 20mhz channels with different power settings. at full power 25db you could only run two cards if they were on on channels 5745 and 5825 and you woud "get by." Even then they are still seeing each other at -93 on the edges.

Here is my network diagram right now. As of right now the PURPLE 900mhz AP's are not there but this is so you can get the idea of what I want to do. Basically I already have a 5ghz infastructure I just want to add the 900mhz for roaming and utilize my backbone already.

Re: how do you setup seamless roaming with WDS?

1. You'll either need to setup static or dynamic WDS links between the APs. 2. No the clients do not need to be Mikrotik. 3. You will need to put the WDS and WLAN interfaces in an RTSP or HWMP+ bridge. Read about RTSP http://en.wikipedia.org/wiki/Spanning_tree_protocol and HWMP+ http://wiki.mikroti...
