Due to the overhead caused by the SHR, PHR as well as the FCS, the effective data rate is
lower than the selected data rate. This is also affected by the length of the PSDU. A graphical
representation of the effective PSDU data rate is shown in Figure 11-7 on page 138 .

PSDU length in octets
The effective throughput is further affected by the MAC overhead, the acknowledgment scheme
as well as the MCU processing capability. Consequently, High Data Rate transmission and
reception is useful for large PSDU lengths due to the higher effective data rate, or to reduce the
power consumption of the system. When using High Data Rate Modes the active on-air time is
significantly reduced.

High Data Rate Frame Buffer Access
The Frame Buffer access to read or write frames for High Data Rate transmission is similar to
the procedure described in Section 6.2.2 “Frame Buffer Access Mode” on page 20 . However,
