Throughput barrier for 3.3 miles ?

Hi

I installed 4 340 Wireless Bridge for remote network access.

Two is connected via yagi antennas between 0.5 miles distance and one of these bridges in located in a tower and connected to another 340 Wireless Bridge via a hub and these brigge is connected to a parabolic dish with communicates to another dish from 3.3 miles distance and fourth bridge is connected this dish.

Here is my question?

After connection established i made bandwith and download tests beetween two connected networks connected by wireless equipments and couldnt pass

2.5 Mbit per second.

I runned signal test via Bridges's web management interface and i got app %75 signal quality level and %60 signal strength level beetween yagi's and %60

signal quality level and %50 signal strength level beetween 3 dishes...

Techology supports up to 11Mbit/s but is it possible

to get app 4 or 5 Mbit/s bandwidth in this case.

Thanks in advance

Re: Throughput barrier for 3.3 miles ?

For preinstallation calculations, you should consult the Bridge Antenna Calculation tool at http://www.cisco.com/warp/public/102/us-calc.xls

There's also a document on Cisco.com about the errors on a bridge and how to interpret them at http://www.cisco.com/warp/public/102/errors.html

However, given that you only have 50% signal strength and 60% signal quality on some of these links, I would imagine that environment is what's causing you trouble. Some sites where there is a great deal of radio interference around simply are not good candidates for wireless. That is the major reason why wireless resellers are supposed to survey sites before deploying the hardware.
