FSK modems are inefficient in their use of bandwidth, with the result that the maximum data rate over normal telephone lines is 1800 bps. Typically, for rates over 1200 bps, other modulation schemes are used.

What is FSK rate?
The FSK rate is the rate at which the output frequency "shifts" between the carrier frequency and the hop frequency using the internal FSK source. FSK rate (internal source): 125 µHz (33500 Series) or 250 µHz (33600 Series) up to 1 MHz, default 10 Hz.
How do I calculate FSK bit rate?
What is the maximum bit rates for an FSK signal if the bandwidth of the medium is 12,000 Hz and the difference between the two carriers is 2000 Hz. Transmission is in full-duplex mode. – Baud rate = BW - (fc1 - fc0 ) = 6000 - 2000 = 4000 – But because the baud rate is the same as the bit rate, the bit rate is 4000 bps.
What is the baud rate of FSK?
The basic modulation is continuous-phase binary FSK at 1200 baud between 1200 Hz (mark) and 2200 Hz (space). The only supported baud rate is 1200.
What is FSK modulation used for?
Frequency-shift keying (FSK) is commonly used over telephone lines for caller ID (displaying callers' numbers) and remote metering applications.
