High bandwidth over bridge connection?

[a.kiprawih]

Is there any possibility to get more than 11Mbps of transmission speed over wireless bridge, .e.g binding 5 wireless bridges to get 55Mbps?

Thanks.

Hi ,

In case of 802.11b there are 3 non overlapping channel , 1 , 6 and 11 . So you can

use aggrgation of 3 pairs of brigde and overall you can get 33 meg .

So

br1 ---------br1a

br2-----------br2a

br3------------br3a

put ever pair on non overlapping channel and have different ssid .

Thanks

You can do this as Nilesh suggests, however, in order to bind these and provide for an aggregated bandwidth using these three channels, you'll need to provide load balancing from either a router or switch.

Hi Nilesh/Bill,

Since this setup is limited to 3 non-overlapping channels only, looks like 33Mbps will be the max. bandwidth available. Any other options?

Thank you for the info.

Rgds,

... and could we use only one antenna for this trunk ??

[btillery]

Each bridge will require an antenna. In this configuration, you'll use six antennas, six bridges and two routers or switches. The bridges would be configured to use channels 1, 6, 11.

--> br350 --> antenna antenna <-- br350 <--

router/switch --> br350 --> antenna antenna <-- br350 <-- router/switch

--> br350 --> antenna antenna <-- br350 <-

Hello

I think agregatting channels is not as simple as it seems. If you simply use three bridges in each site connected to a switch, you may be would have STP problems, but if trying etherchannel configuration, load balancing would be done by processing packets attending to dest or source mac, so no load balancing if trying to connect two machines (i've found that once). You could not calculate the agregate bandwith by ftp from server to client.
