SkyOFDM is a high speed modem based on the OFDMOrthogonal Frequency-Division Multiplexing and turbo coding technologies. It offers several baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. rates (300-9600 bpsBits per second (bps)) and two different interleaving options (short and long). Also there are two bandwidth options: 2000Hz (OFDMOrthogonal Frequency-Division Multiplexing 22 tones) and 2400 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). (OFDMOrthogonal Frequency-Division Multiplexing 28 tones).
At least two times the signal has been able to locate it to Southern Finland.
