Multi-Site Repeat Operation
The Multi-Site Repeat mode is the most flexible method to allow messages to be delivered to
multiple radio technologies concurrently. This means messages can be sent to POCSAG
pagers at different speeds and on different frequencies if required. DMR radios can be
supported concurrently. Messages can be sent to all sites at high data rates for low latency,
multi-site transmission. Continuous coverage across the site is shown through blue, green and
red area crossover.
This mode of operation relies on the use of the WT Output Control protocol. Using this
protocol, any message for transmission can be steered to some or all TReX units at the same
time.
In the following examples the central controlling TReX unit is configured to be unit “01”.
This TReX unit is managed either from a direct connection to a PC or through an Ethernet
connection to a remote PC.
In this example units “02” and “03” are considered as repeaters. These units must have their
receivers configured to a frequency and data rate that suits the installation (all units must be the
same). This receiver rate may much higher than the repeater transmit rates. For the following
examples, the rate between sites is fixed at 2400 baud, for a 12.5kHz channel.
