View Full Version : WAR2 - Unexpected Performance

I have a WAR 2 board on one of our towers setup as an AP serving a select handfull of clients who are all WRAP/StarOS/CM9 and all links are hardset to 12mb. Speed test to client 5km away (with an RSSI of -82) is around 3500KB/sec which looks to be CPU related on the WRAP. I have now added another WAR2 board as client to this same AP but at 18km away with a much larger antenna (with an RSSI of -80). Speed test to WAR2 client I am only able to achieve 2000KB/sec.
Should the difference in distance make this much difference to the throughput even when the signal seems to be better?
I am doing something very similiar did you get your question resolved ?

Nope, no responses unfortunately.

It is a signal issue. Get your signal to -75 dB or better and you will see better performance.
What sort of throughput would you get at -80 dB with an Orinoco or prism2? Viewed that way you have achieved an excellent increase and should not be too unhappy.

Hmm, if I can get 3500KB/sec at -82 but only get 2000KB/sec with a better signal how could it be a signal issue?

I stand by the statement it is a signal issue. First off it is too low and second you probably have interference. A stronger signal will fix both issues.
We see 3,500 at 43 km using 3 foot dishes with -70 dB signals.
