5.1. Working with Parallel Repeaters
When Repeaters are added to a network, plan accordingly to avoid creating a parallel Repeater
scenario. A parallel Repeater is defined as two or more Repeaters linked to the same point in the
network.
l Repeaters Data Transmitted on the Same Frequency Key (on page 98)
l Adding a Repeater to the Network (on page 99)
5.1.1. Repeaters Data Transmitted on the Same Frequency Key
In this diagram, the Slave radio in the middle has overlapping coverage from both the Repeaters
(parallel Repeaters). Data from the Repeaters is transmitted on the same Frequency Key in the
same time slot, which creates message collisions.
Figure 25: Slave Radio with Overlapping Coverage
To resolve this scenario, change these settings on one or more of the Repeaters in conflict:

Setting Description
Repeater
Frequency
l Set the Repeater Frequency parameter in the MultiPoint Parameters tab to
any number other than 0.
l If set to a number other than 0, the radio uses the frequency key set in the
Frequency Key parameter in the Transmission Characteristics tab, instead
of the frequency key assigned to the Master.
Frequency Key Set the Frequency Key parameter in the TransmissionCharacteristics tab to a
key other than that of the conflicting Repeater.
