antenna divirsity in RouterOS !

Thu Jan 04, 2007 9:26 pm

i searched the forum about this topic but i didnt find something to help me ,,

i want to make a WDS connection at many areas with RB532 and SR2 using RouterOS, and i want to connect the radio with 2 Antennas , one is high directional antenna to connect directly to the Other WDS radio far a way , and can make long distance connection (24 dbi dish) .

and also connecting the other MMCX connector with 12 dbi omni 360 degree , and this one for the client around this WDS radio , to connect with .

i want the 2 antennas to perform diversity for sending and receiving this means the radio will choose the better antenna for its current receiving or sending status ,,

the result SHOULD be that i can connect all the roaming users around this WDS radio , and also the WDS radio can connect to the Base station or other WDS station far away to act as a backbone , with only one radio on the RB532 board .

i think this senario could not be performed with NetStream offcourse (be aware i want roaming laptop users with their internal wireless card (not an MT based router) to connect directly to the WDS ) .

Does the diversity in RouterOS can perform this senario ?

thanks ...

No. Antenna diversity is currently not supported by RouterOS.

ok that means it should be 2 cards at least to perform that ? or just depend on the omni to do the backhaul connection and also make the connection available for users ?

You really need two radios.

I've done this type of connection as a test with a Linksys WRT54GL and results were not good. Enabling diversity in this situation will increase latency, cause network drops, etc.

ok i changed the plans ,,

i will use 2 radios , SR2 and (R52 or cm9) , one of them i will use to act as a client to WDS or a WDS or a client ot base station ,

and the other radio i will use to radiate the signal 360 degrees for the users around to connect ,,

i will use RB112 to reduce the cost , and i know that the maximum power for RB112 is about 12v , 5 for the board and there is 7 left for the radios ,cm9 i think needs only 2v and SR2 needs 4v ,

my question , which is the best to perform , SR2 to act as backhaul and cm9 for 360 degree , or the reverse cm9 as backhaul and SR2 as 360 degree for the users to connect with ?

do you recommend one of the 6th generation radios from Senao instead of cm9 or R52 ?

thanks ..

cm9 or r52 for backhaul (if you have enough signal) sr2 for omni

beware both thise cards are very sensitive and will pick up noise if you are in a crappy area

I suggest going with the R52 over the CM9. I have replaced a couple CM9's that failed for environmental reasons with R52's, signal levels improved quite a bit and performance was much better. I had a link that was operating at 24/36mbps in 802.11a and it's now 54mbps pretty steady with an occasional drop to 48mbps.

I highly recommend the R52 card.
