1.5.1.1.1.2 Single Sector 4x4 with MU-MIMO
Downlink Multi-User MIMO (MU-MIMO) topology is supported for higher sector throughput
with enhanced spectral efficiency optimized for fixed wireless. This mode of operation is
supported in single sector with Compact’s configuration to be used is 4Tx/4Rx.

1.5.1.2
Two Geographical Sectors:
1.5.1.2.1
Split Mode 2x2
This topology covers two geographic sectors / areas, where the split mode is ideal for small areas
with a low number of subscribers, each geographical sector can be configured in the same
frequency F1F1 or different frequency F1F2.
Figure 10: Split Mode 2x2 Topology
The Single Carrier Using Split Mode topology enables deployment on a single BreezeCOMPACT
unit to cover two geographic areas. In this mode, single carrier bandwidth (for example,
20/10MHz) is used. The capacity of the single carrier is shared over both the geographic areas.
There are two options for Split mode:
 Split Mode default mode - using the same frequency for the two 2x2 sectors where
the two antennas are back to back
 Split Mode f1f2 - Using different frequency for each 2x2 sector
The capacity of single carrier (5, 10, 14, 15, 20 MHz) is shared between the two sectors in both
cases.
Handover is not supported in Split mode.
