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).
