Point to Multipoint via Repeater (PTMP via Rep)
A Point to Multipoint via repeater (PTMP/R) network is a variation of the Point To Multipoint (PTMP) network. It is normally
chosen when the site where the Host application (i.e.: Entry Point) does not have adequate RF coverage of Remote sites in
the network.
This network topology consists of a radio configured as a Repeater (typically full duplex), an entry point radio and a number
of remotes. The repeater can be configured to repeat data based on either IP layer 2 (Bridge mode), or IP layer 3 (Router
mode) rules.
The repeater should be located at a site with adequate RF coverage to each of the remotes.
For two frequency systems, to facilitate efficient data communication and support features such as digital collision avoidance,
it is recommended that the Repeater be a full duplex radio (QB/QH).
Utilising a half duplex Entry Point radio is possible, however some features may not be available and system performance may
be lower when compared to using a full duplex entry point.
Other aspects of the Point to Multipoint network apply to this network topology.
