Topology refers to the shape of a
network,
or the network's layout. How different nodes in a network
are
connected to each other and
how they communicate, is determined by the network's
topology. The
NL900PRO supports a Point-to-Point and
a Point-to-Multipoint network topology.

A point-to-point network consists of a single Server
and Client pair. Sometimes
referred to as a wireless
bridge, a point-to-point link replaces a single communications cable.

Point-to-Multipoint
systems have one base station, or access point, that controls communications with all of
the other wireless nodes in the network. This allows for the creation
of a wireless network consisting of
multiple
nodes. By programming each NL900PRO with a network specific Channel Number and System ID
multiple networks can be created.
