HSS Implementation
Figure 9‐3: Collocated units using Hub Site Synchronization (2)
9.3 HSS Implementation
HSS is implemented using a master (which transmits synchronization pulses), where the rest
of the co‐located units are defined as clients. These client radio units synchronize their
transmission to the pulses received by the master.
HSS can be carried out between all co‐located RADWIN radio products, so long as they are
defined as a base station.
9.3.1 Radio Frame Pattern
The synchronization signal is transmitted once per a specific time period, and determines
when the co‐located units will transmit and when they will receive. This cycle of transmit and
receive is called the Radio Frame Pattern. Figure 9‐4 shows the Radio Frame Pattern of 3 co‐
located outdoor units (ODUs).
Figure 9‐4: Radio Frame Pattern
If the master is one of the co‐located ODUs, it is called the Hub Site Master (HSM). The other
co‐located ODUs are called the Hub Site Clients (HSC).
