Task 6: Configuring radio parameters
MIMO-A mode of operation for PMP 450i
In releases prior to System Release 13.2, PMP 450i supports MIMO-B mode using the
following modulation levels: QPSK, 16-QAM, 64-QAM and 256-QAM. System Release
13.2 introduces MIMO-A mode of operation using the same modulation levels as the
MIMO-B mode. With MIMO-B, the PMP 450i radio sends different streams of data over
the two antennas whereas with MIMO-A, the PMP 450i radio uses a scheme that tries
to optimize coverage by transmitting the same data over both antennas. This
redundancy improves the signal to noise ratio at the receiver making it more robust, at
the cost of throughput.
In addition to introducing MIMO-A modes, improvements have been made to the existing
rate adapt algorithm to switch between MIMO-A and MIMO-B seamlessly without any
intervention or added configuration by the operator. The various modulation levels used by
the PMP 450i are shown in Table 39.
