Baud rate explanation needed - MSK modulation

sgergo said:

Hi to all,

I'm working with a wireless module capable of transferring data with 500 kBaud. I initially thought that to transfer 1 byte I need 10 bauds (start/8bits/stop) but I just read somewhere that in FSK modulation 4 bits equals 1 baud (???). The module uses MSK (minimum shift keying) which is a form of FSK.

Now I'm not sure what kilobit/sec data rate is 500 kBaud exactly in MSK modulation. Any help or explanation would be much appreciated. Thank you.

Isn't Baud Rate measured in units of bits per second?

Meaning, a Baud Rate of 500K (bps) means that every (10/500K)sec 10 bits are sent? [1 (8-bit)byte of data + 1 start bit + 1 stop bit].

AFAIK baud means one meaningful state change in the signal. If you transfer one byte with 10 bauds then 500 kBaud is 50kB/sec. If you don't need the start and stop bits then 500 kBaud is 62.5 kB/sec. Correct me if I'm wrong.
