A PTMP via multiple repeaters system is a variation of the PTMP/R system. It is normally chosen when the site where the Host
application (i.e.: Entry Point) together with the first repeater have inadequate RF coverage of remote sites in the network.
In this system topology, there are multiple radios configured as repeaters. The PTMP/R with multiple repeater system
topology is only possible when using IP routing mode. Each repeater is configured to repeat traffic based on destination IP
address.
The repeaters should be located at sites with adequate RF coverage for the remote sites. For two frequency systems, to
facilitate efficient data communication and support features such as the collision avoidance mechanism, it is recommended
that the first Repeater be a full duplex radio (QB/QH).
Utilizing a half duplex Repeater 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.
