HSS Concepts: Radio Frame Pattern (RFP)
A Radio Frame Pattern (RFP) is the cycle duration of transmit and receive of the air‐frame.
Without HSS
When selecting TDM or Ethernet services, the system automatically and transparently
chooses the optimal RFP. When TDM and Ethernet services are configured, the RFP is
optimized for TDM.
RFP and HSS
When HSS is used, the RFP for the collocated radios must be selected manually.
RADWIN 2000 uses the Time Division Duplex (TDD) mechanism.
Under HSS, TDD enables synchronization of transmission for the collocated units as shown in
Figure 13‐4:
Figure 13‐4: Radio Frame Pattern
Two RFP types (labelled B and E) are available. Under HSS the RFP must be configured by the
user depending on the type of the radio products, services and channel bandwidth in
accordance with Table 13‐2.
The table describe the efficiency of the air interface according to the RFP type, services and
channel bandwidth. The tables may also be viewed in the RADWIN Manager and in the Link
Budget Calculator. The efficiency of the air interface will vary according to the product used.
