Data throughput in DSSS and GFSK modes of transmissions

Question: What is the data throughput in DSSS and GFSK modes of transmissions ?

 

Answer:

For DSSS modes, the user’s data is encoded in a series of chips, based on the configuration register settings. In raw GFSK mode the chips transmitted over the air are equivalent to the user’s data. Regardless of the user selected data rate, the rate that information is actually transferred over the air (the chip rate) is always 1 Mbps. Different DSSS data rates are achieved by encoding a different number of bytes in each symbol.
