A.2 Fourth Order Diversity, Beam Forming
and MIMO
This section describes the configurations that enable support of both Beam
Forming and MIMO technologies.
Only ODUs that support Beam Forming should be used.
The example is for two 4x2 ODUs, where only the Tx/Rx ports are used. 2x2
ODUs can be used instead, as well as a combinations of one 4x2 ODU and one
2x2 ODU in the same sector (provided that the two ODUs use the same frequency
band).
In the current release a Double Dual Slant (DDP) antenna should be used to
support Beam Forming.
