i think this very normal because you running the 125 mbits lite version. if you upgrade to full 450 mbits licence version, you will have at least 225mbits and maybe more.
It's normally useful to see the LINKPlanner file for a PTP link, and in this case we don't know if the links has any obstructions. The PTP 650 units are reporting a Link Loss of about 145.3 dB. If we work in dB, the measured Link Loss is the difference between the transmit power and the receive power, plus the antenna gain at each end, like this:
24 - (-62.3) + 30 + 29 = 145.3 dB.
We can find the expected basic loss of a line of sight link from this formula:
For 5.8 GHz and 30.7 km, the expected line-of-sight loss is 137.5 dB. This is about 8 dB lower than the measured Link Loss. This 8 dB discrepancy could be due to:
Obstructions within the Fresnel zone of the link
Actual antenna gain lower than 30 dBi or 29 dBi
RF feeder loss in the installation but not entered into the PTP 650
Alignment error in the antennas
Are any of these likely explanations? Can you share the LINKPLanner predictions with us?
As the previous contributor pointed out, this link has the Lite capacity license. The aggregate capacity at present is 102 Mbit/s. If you upgrade to the Full capacity license, the link capacity will increase to about 360 Mbit/s.
