3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES

5.1.5 WLAN P

ARAMETERS

The WLAN Parameters Menu contains the following
sub-menus:

Hopping Sequence

The hopping sequence is a parameter that is set for
the Hub. The stations learn it from the Hub at the
association process.

Changing this parameter is useful when several Hubs
are co-located. This reduces the probability of frame
collision between co-located cells.

Range

The Hopping Sequence must be in the range
between 1 and 22.

Default Value

The default value is 1.

Access Rights

This value is read-write on the Hub, and read-only on
the stations.
