5.3.6 IP Multi-site Connect
How to select frequency and color code in IP Multi-site Connect network? You can
select the proper networking scheme as per your actual needs. In the overlapping
area, it is recommended that the frequency of the repeater be different, but the color
code can be the same or varied. For adjacent repeaters sharing the same frequency,
it is better to use different color code to avoid probable interference.
What is the difference between IP Multi-site Connect network system and simulcast
system
1) In a simulcast system, the Switch center or server is a must, which is used to
receive and transmit data and time sequence. And the repeater acts as a transceiver.
Therefore, the Switch center or server shall be available at any time, and a hot
backup is required If necessary.
For IP Multi-site Connect network, there is no independent Switch center or server.
One repeater operates as the master one and other repeaters as the slave ones.
Each works independently.
2) The simulcast system is capable of time sequence synchronization, enabling the
transceiver to use the same frequency in overlapping area, but in IP Multi-site
Connect network, different repeaters shall use different frequencies to achieve
quality communication.
3) At present, the IP Multi-site Connect network supports 15 repeaters at most, while
the simulcast system has no limit on the number of repeaters.
Terminals (portable radio and mobile radio) in single site mode can communicate
with those in IP Multi-site Connect mode. If you want to upgrade the single repeater
system, you just need to upgrade the existing software and configure all parameters
again for the repeater and terminal.
The API application configured for the terminal in single repeater system can work
normally in IP Multi-site Network without update.
Can other repeaters work normally when one of the repeaters fails? Yes. The entire
network is similar to a peer-to-peer network. The Master repeater is used for
registration and broadcasting address. If a Slave repeater disconnects, the Master
repeater can detect and broadcast it to other Slave repeaters; if the Master repeater
disconnects, all Slave repeaters still can work. However, new address can not be
added and the status of other repeaters can not be acquired until the Master
repeater restores to normal operation.
