Max Range
Enter a number of miles (or kilometers divided by 1.61, then rounded to an integer) for
the furthest distance from which an SM is allowed to register to this AP. Do not set the
distance to any greater number of miles. A greater distance
◦ does not increase the power of transmission from the AP.
◦ can reduce aggregate throughput.
Regardless of this distance, the SM must meet the minimum requirements for an
acceptable link. If the AP is in cluster, then you must set this parameter on all other APs
in the cluster exactly the same. The default value of this parameter is 2 miles (3.2 km).
In Release 4.2 and later releases for 2.4-GHz links, although the typical maximum range
where an SM is deployed with a reflector is unchanged at 15 miles (24 km), you can set
this parameter to as far as 30 miles (48 km). Without affecting the performance of the AP
or SM, the greater value allows you to attempt the greater distance where the RF
environment is uncontested and the Fresnel zone is clear.
