hi again, i wonder if here any mk user who realy did wireless full duplex simulation and got double bandwidth? I've tried all methods for simulating full duplex and coudn't achieve any good results..
i've made another lab , and try to simulate full duplex using just simple static routing..
I should attach some animations for being more interesting… make my posts more attractive… this is the third time i post about the same issue and no one peplies…
how many topics should i open for getting the answer…!!!
i’ve tried it… i launched two BT from each leptop (udp, send) and results were terrible…
i think there is no interference between radios, because they are operating in different frequencies (see topology )…
p.s i also tried that topology using two rb433 per site, but results were same…
Is this bonding of two N links?
On u’r second picture with the result of 2 tests on both picture btest is made to 20.20.20.20?
the test should be like from 2.2.2.1<->2.2.2.2 and 1.1.1.1<->1.1.1.2
why not you try the V5.0Beta_6?
i have try with it on the 11a card with MPLS setting, and running on the 40Mhz channel bandwidth for 12KM with 27dbi patch antenna..
it can achieve udp 70Mbps full duplex and tcp 40Mbps full duplex with RB433AH.

it is not bonding, just AP—>station
20.20.20.20 is the ip address of second leptop on the other side… i’m testing through the routers.. it shows more realistic results…

I tried mpls bridges, eoip, also bonding but i couldn’t combine these two speeds…
i used also router os beta versions all this configuration and after no success i downgraded it to version 4.11
i can achieve 80mb udp full duplex per wireless link, its not problem with N cards, but i need at least 150 mb fulll duplex…the main problem is combining these two 80mb full duplex links..
i’ve tried also ethrchannel configuration between two cisco switches. i configure two links as transparent bridges (with MPLS).. But you can’t build ether channel over half duplex links.. there were a lot collision on the swith ports…
what’s your distance for this link?
i have tried with the http://www.lanbowan.com dual polarity antenna..
with the RB800, on the 800Mhz cpu speed, i can achieve 85Mbps full duplex.
If i overclock it to the 1Ghz, it can up to 95~99Mbps, both talking on the tcp test, but overclock make it unstable.
thus, i believe you may need it with the PC based to make it stable.
i just realize that, Lanbowan having 34dbi dual polarity antenna with competitive price.. try to get it..
ops… fyi, the bonding always take the lower speed link as the standard, thus, if one of the link performance drop let say up to 20Mbps only, no matter how good the other link like can up to 80Mbps, it’s also just can run on 20Mbps for both link as what i experienced.
hi, there is no problem with single wireless link, both of them are working properly… i just need to combine these two links to get maximum throughput..
it’s an interference issue…
try using 2 boards and keep them far apart as more as you can on your sites. To bond them use ospf.
Or you can try using nstreme dual, but i don’t think it will satisfy your needs
i’ve used four routerboards.. also ospf config and nstreme dual, but last one seems like doesn’t works well with N standart..
i cant imagine what can be the problem , i have almost half duplex 150-180mb-s with this configuration, but when i’ m testing full duplex udp or just tcp the speed is very low…
i think there is some collisiom problem, maby…
i tested that configuration in wired environment, works great..
today i was testing full duplex simulation with 802.11 g standart and it works great, i’ve combined two 20mb links and got almost 40mb throughput with Nstreme, also with routing.
so i think that simulation of the full duplex doesn’t works in 802.11n… maby,
