We are trying to develop a transceiver for the european 870 ism band
But we need to send at least 7200 bps in a 12.5 KHz channel.
So we need a 60 db atenuation at 6 kHz from the carrier.
The question is:
-Is it possible to achieve this data rates using the fsk modulation
(continuos phase)?
- Even better, which is the maximum data rate using CPFSK
modulation, in a 12.5 KHz channel system, with maximum deviation of
+/-1.5 KHz and with an attenuation of at least 60 db at
6 kHz from the carrier?

Thanks in advance!!
