Adaptive modulation
PMP 450 units can transport data over the wireless link using a number of different modulation modes. The radio
automatically selects QPSK (Quadrature Phase Shift Keying), 16-QAM (Quadrature Amplitude Modulation), or 64-
QAM based on the RF environment to provide 2x, 4x, and 6x operation.
*
PMP 450 devices include two antennas, vertical and horizontal. Listed receive sensitivity corresponds to the combined
horizontal and vertical receive powers. The PMP 450 management interface displays receive power level readings as a
combination of the vertical and horizontal power levels.
