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 the ‘Channel Share+’
collision avoidance mechanism, 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.
