8.6 Higher Data Rates
To support the demands of applications that require high data throughputs such as in audio or data streaming
applications, the JN5148 supports higher data rate modes that offer 500kbps or 667kbps on air transmission rates.
The switching between standard and higher data rates is controlled via software, When operating in a higher data
rate mode standard IEEE802.15.4 features, such as clear channel assessment, can still be used. This allows the
JN5148 in a higher data rate mode to co-exist in an IEEE802.15.4 based network (adhering to the correct bit rates
and frame timing etc.) whilst at the same time providing the benefit of the higher data rate where required.
When operating in a higher data rate mode, the receive sensitivity will be degraded by at least 3dB.
