14 TDD Synchronization Configuration and Installation Guide
14.1 Introduction
When planning a network of links, a key consideration is the interference that exists between
the links. TDD synchronization is a feature which eliminates two specific interference
mechanisms, namely interference between Master and Master and interference between
Slave and Slave.
TDD synchronization is not available in the PTP 48600 and PTP 49600 product variants.
One example which highlights the need for TDD synchronization is the case where a number
of links are required from a single mast. Without TDD synchronization, high levels of
interference will occur between the units on the mast due to their close proximity. By enabling
TDD synchronization, interference between these units is eliminated if all are of the same
type. The recommendation is for all units on a mast to be configured as Masters. The
maximum number of links on a mast depends on the customer requirements such as required
throughput, link availability, available spectrum, maximum EIRP, bandwidth, channel
separation and the longest link. However, in some cases, it may even be possible to re-use
radio channels on the same mast which would not be possible without TDD synchronization.
In summary, by eliminating interference between units of a like type, TDD synchronization
increases network capacity by increasing frequency re-use and increasing the density of links
across the network.
This section will cover the two steps required to enable TDD synchronization:
• Physical installation of the GPS Synchronisation Unit. This will include wiring diagrams,
illustrations showing the placement of the GPS box and the recommended components
for installation.
• The latter will describe the step by step configuration process using the Web interface.
