•
Link Distance – Match to the longest distance link in the network.
•
Frame Length – Match to the lowest frame length to optimize total system latency (for example,
for TDM networks) 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.
External Synchronization
Use an external GPS source as an alternative to the internal synchronization source for system
synchronization. This is ideal for links that are nearby each other, but are not directly collocated at the
same site. Figure 7 illustrates using a GPS source for the primary synchronization at a typical site with
collated radios.
Figure 7 GPS as primary sync source using AUTO SYNC
Figure 8 illustrates two separate radio locations benefiting from synchronized GPS sources.
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.
