NETWORK TOPOLOgIES
Topology refers to the shape of a network or the network’s layout. How different nodes communicate with each other is
determined by the network topology. The CL2510s support a point-to-point and a point-to-multipoint network topology.
The CL2510s do not support multi-hop meshing or any repeater functionality by default.
POINT-TO-POINT
a point-to-point network consists of only two radios, one configured as a Server and one configured as a Client. Sometimes
referred to as a wireless bridge, a point-to-point link replaces a single communications cable. It does not matter which node is
the server and which node is the Client as both nodes will support bidirectional serial data in the same manner.
POINT-TO-mULTIPOINT
Point-to-multipoint systems have one base station, or access point, that controls all communications with all of the other
wireless nodes in the network. This allows for the creation of a wireless network consisting of multiple nodes. In a
point-to-multipoint network the Server would typically be set up as the access point and would be configured to transmit
Broadcast Packets. The other nodes would be set up as Clients and set up in Addressed Mode (most likely using Auto Destination).
Data received on the server’s serial interface would be transmitted to all Clients in range. Data received on the Client’s serial
interface would be transmitted only back to the Server. There is no limit to the number of Clients that can be configured in a
point-to-multipoint network, but all radios would share the same bandwidth over the rF, so as more nodes were added care
should be taken when transmitting data to prevent collisions.
