How to calculate the data rate of IEEE 802.15.4 to be 250 kbps

• Could you rephrase a little the title from the content ? – Gilles Nov 3 '16 at 22:06
• The standard says that at 2.4 GHz band the over the air data rate of the channel is 250 kbps, but i am looking for its justification as if how this value is calculated? – Linux-Fan85 Nov 3 '16 at 22:07
• Could you include that (and other info you have) in your question ? – Gilles Nov 3 '16 at 22:10
• 4 bits per symbol and 62.5 kbaud, the link might help it contains all the details of the standard [link (ecee.colorado.edu/~liue/teaching/comm_standards/2015S_zigbee/…) – Linux-Fan85 Nov 3 '16 at 22:42
• The rate is not really calculated, it is specified. – MBaz Nov 3 '16 at 23:02

You have $16$-ary symbols, each symbol requires $4$ bits. With a chip rate of $1000$ K, the symbol rate is $1000/16=62.5$ K, hence the bit rate is $4\times 62.5=250$ Kbps. Did you mean this calculation?
