A Point to Multipoint via repeater network is a variation of the Point To Multipoint network. It is normally chosen when the site where the SCADA
(i.e.: Data) entry point does not have adequate RF coverage of other Remote sites in the network. The network diagram is shown below.
In this network topology, the Access Point radio is configured as a Repeater. The repeater should be located at a site with adequate RF coverage
to each of the remotes. The Repeater still behaves as an Access Point to the Remotes as in a Point to Multipoint network, but the Repeater is
configured to repeat data messages between remotes in the network. It therefore allows peer to peer communication to occur between remotes.
Because the Access Point radio now needs to “Repeat” data, data latency for messages from the Host Application to/from the Remotes will be
longer. However, the Repeater/Access Point is normally a full duplex device and this means it is capable of receiving and transmitting repeated data
simultaneously.
All other aspects of the Point to Multipoint network apply to this network topology.
