On the "local" side you have a lot of noise. Although the the "constant" noise on the channel shows as -90-ish (shown as the solid blue bars) the radio is seeing -70-ish peak noise (shown as the black I beams). Your receive signal is -63 so you only have about 10db signal above the noise.
If you have control of the spectrum at that site and can move the other devices to other channels then you should be able to get more throughput. This is why we went with licensed ptp at almost all of our towers...it keeps the unlicensed spectrum available for pmp. If you try to do ptp & pmp together in the unlicensed spectrum you can quickly run out of room for everything and cause a lot of self interference. (Not certain that is what's happening here but that's what happened to us) -sean On Wednesday, July 15, 2015, Daniel Gerlach <danielgerl...@gmail.com> wrote: > can somebody have a look on the pictures and can tell why the > modulation is so low :( > > spectrum is free..and LOS > > what does this peaks can be.. > > THX a lot >
