What kind of a site survey was done? Do you have a clear channel across the
whole range? How's the SNR?
Remember that wireless is half-duplex anyway, so you'll always have less
than perfect throughput, but 6-8 may still be a bit lower than expected.
Try measuring a burst of something not requiring acknowledgements to measure
the wireless throughput rather than a tcp transmission.
Try turning off your encryption stuff in order to see if that's causing
somewhat of a bottleneck as well.
How many other devices are in contention for sending traffic?

Subject: Cisco 1310 P-t-P Throughput too low
Hi Guys,
We setup a point to point bridge between two trailers. They are about 300 m
away. The throughput we test via FTP is just about 6-8Mbps. I opened a tkt
with Cisco, but not too much help so far. Could somebody please give some
suggestion. Below is the configuration.
We tried to adjust antenna, but the Signal of Strength is still not good.
