Simplex "Peer-To-Peer; Peer-To-Peer With Repeater Assistance - Microwave Data Systems MDS 9810 Installation And Operation Manual

Simplex "Peer-to-Peer"

Peer-to-peer communication is possible using the transceiver's simplex
mode. With this arrangement (Figure 4), two or more remote units can
share information by direct communication with each other in addition
to communicating with a central master radio. This is possible because
the transmit and receive frequencies for each hop channel are the same
at each radio when simplex mode is enabled. If adequate transmission
paths exist, each radio can communicate with all other units in the net-
work. Additional details for peer-to-peer systems are provided in
Section 4.2 (Page 19).

Peer-to-Peer with Repeater Assistance

Peer-to-peer communication is also possible using this alternate
arrangement (see Figure 5). It overcomes the range limitations of a sim-
plex peer-to-peer system by using a repeater to re-transmit the signals of
all stations in the network. The repeater consists of two radios—one pro-
grammed as a remote using master frequencies ( command),
MODE R-M
and the other programmed as a conventional master. Additional details
for peer-to-peer systems are given in Section 4.2 (Page 19).
