The effective data rate is smaller than the selected data rate due to the overhead
caused by the SHR, the PHR and the FCS. The overhead depends further on the
length of the PSDU. A graphical representation of the effective data rate is shown in the
following figure:
Figure 9-31. Effective Data Rate “B” for High Data Rate Mode
Therefore 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.
Furthermore the active on-air time using High Data Rate Modes is significantly reduced.
The Frame Buffer access to read or write frames for High Data Rate communication is
similar to the procedure described in
in the Frame Buffer after the PSDU data is the ED value rather than the LQI value.
According to IEEE 802.15.4 the ED measurement duration is 8 symbol periods. For
frames operated at higher data rates the automated ED measurement duration is
reduced to 32 µs to take the reduced frame length into account
