Virtually any combination of hubs and repeater sites, star configurations, and/or backbones can be
implemented with synchronization. It is typically necessary or ideal in each configuration to match the
following parameters on every radio in the network:
• Link Distance – Match to the longest distance link in the network.
• Frame Length – Match to the lowest frame length to optimize total system latency or match to a
highest frame length to optimize user throughput. Choose an intermediate value to compromise
between latency and throughput.
• Mode – It is desirable, but not always necessary, to match the mode for all collocated links.
• Bandwidth – It is desirable, but not always necessary, to match the bandwidth for all collocated
links.
For complex networks, an Exalt engineer should review multi-link networks before deployment as
several factors can optimize the network for desired performance.
Figure 3 illustrates two separate radios benefiting from synchronized GPS sources.
Figure 3 Synchronized GPS sources
Figure 4 illustrates the recommended synchronization method for two links that share a common site at
one end of each link. Using internal sync, a cable can be connected between the two radios to
accomplish sync. No GPS receiver is required. This approach cannot be used for more than two
collocated radios.
Note: When GPS Sync is enabled, link initiation typically takes 1 to 3 minutes to allow for
the radio to properly synchronize to the available GPS satellites.
