Diagram 5Distance and Signal Strengthen
λ The signal strengthens (dBm) is negative value, the more little the absolute value of it, the
better the signal strengthens. For the better throughput of wireless network, you should
better adjust the signal strengthen as better as possible.
λ The signal strengthens (Percent) is just a reference value. It lies on not only the real signal
strengthen but also the academic signal strengthen which lies on the Link Test settings. So
you should take the signal strengthens (dBm) as reference while adjusting antenna.
Distance(km) Best Signal Strengthen (dBm)
3 －64 ~ －56dBm
6 －72 ~ －62dBm
10 －75 ~ －67dBm
18 －80 ~ －72dBm
－64～－56dBm, data rate can reaches 54Mbps, So you should adjust antenna to get at least
Example: If the space between wireless bridges is 3km then the best signal strengthen can reach
－60dBm.If get any other trouble outdoor while set up AP. please see
