A.1 Introduction
The 4Motion Access Units implement four transmit/receive channels and are
hardware-capable of supporting adaptive beam-forming and MIMO Matrix B
technologies in all possible configurations (only MIMO Matrix B, only
beam-forming, both beam-forming and MIMO Matrix B in different zones, and
combined beam-forming and MIMO Matrix B). The operation mode is selected via
software, giving the maximal flexibility to select the appropriate mode for each
scenario and for each user.
The following sections explain the proposed antenna configurations that support
the different available diversity scenarios and are prepared for supporting
beam-forming and MIMO Matrix B techniques that are not available in the current
release.
