4.4.1 Withoutsynchronization
Distance separation (vertical or horizontal) must be at least two meters between the edges of the antennas.
Reduce the transmission power.
4.4.2 Withsynchronization
4 collocated base stations mounted back-to-back.
The recommended guard interval between the end/boundary frequencies of the occupied bands of
theneighboring sectors 5 MHz.
4.5 Synchronization settings
To perform synchronization using an external hub, each base station sector must be connected to an AUX-ODU-
SYNC.
The following conditions should be met:
Frame size and DL/UL ratio should be equal on all sync-end units.
The automatic downlink ratio selection is not allowed.
4.5.1 Configuration via web interface
To enable synchronization via web interface:
Go to the section "Basic Sttings" →"Link Settings" → "rf6.0".
Check the box "Use AUX-ODU-SYNC" and click "Apply". Synchronization status and the number of visible
satellites is displayed in the "Device Status" -> "Link Statistics" section.
NOTE
The AUX-ODU-SYNC antenna is not included in the standard packing list. For more information about this
antenna, proceed to the AUX-ODU-SYNC(see page 32) article.
