When I fixed AP1200 with 100mW (20dBm) and watched ACU in notebook as near as possible between AP and notebook, -10dBm signal strenth is indicated by ACU site survey menu as SNR (80dB) and noise level (-90dBm). I understand -10dBm means 10mW. How can I understand the "-10dBm" at the receiveing party.
Next, I change the antennas to Parabolic (21dBi) at AP1200 and the Yagi (13dBi) under the same condition, but there is no changes the receiving signal strenth as -10dBm.
At WGB350, I fixed the tx power as 100mW, but I find the strenth out is 0dBm in the link test menu. Please explain these issues.
We need the more system magine in using outside and insufficent Line Of Singht condition (campus fense video surveillance application).
