Airaya – Fast and affordable outdoor wireless bridges
TIP
If you do not see values streaming across the screen, confirm that both
bridges are powered on and then manually aim the bridges at each other
until the values appear. If you see very few or no values streaming across
the screen, there is probably no traffic going across the radio link. You
can generate traffic by opening additional ping windows or FTP file
transfers on your test stations if you do not have a traffic-generating
program.
The first 20 values displayed on each line represent individual RSSi
values; the 21st represents the average of the first 20 values (e.g.: avg:
19). Focus on obtaining the highest average values.
The key to achieving optimal throughput and reliable radio communication
is to obtain the highest possible average RSSi values for bridges at BOTH
ends of a link. This means you need to run this utility from both ends of a
link to ensure signal strength is good in both directions.
FAST FACT
Optimal RSSi values for field deployments range between 18 and 40. Values
for bench tests can be as high as 75. The disparity between such figures is
normal, due to factors such as loss of signal strength along the wireless path,
alignment differences, environmental issues, and other variables.
