Hub Site Synchronization
What is Hub Site Synchronization (HSS)
When several radios are collocated at a common hub site, interference may occur from one
unit to another. RADWIN ODUs support the collocation of more than two units at a central
site. Like any other RF deployment, the wireless operation is highly dependent on factors
such as available frequencies, the physical spacing between radios, other third party
interfering radios, and whether other RADWIN radios are installed.
HSS does not eliminate the need for careful RF planning to ensure the
design will work as planned. See Site Survey for information on installation
site survey.
Note
RADWIN HSS
The RADWIN HSS method uses carries pulses sent to each ODU, which synchronize their
transmission with each other. The pulse synchronization ensures that transmission occurs at
the same time for all collocated units. This also results in all of the hub site units receiving
data at the same time, eliminating the possibility of interference that could result if some
units transmit while other units at the same location receive.
Figure 13‐1 illustrates interference caused by non‐synchronized collocated units.
