What is Rattlegram?
Rattlegram is used to send Text Messages (Short messages).
It is based on COFDM (coded orthogonal frequency-division multiplexing) technology.
- 160 ms long OFDM symbols
- 6.25 Hz per sub-carrier
- 1/8 guard interval
- differentially encoded PSK (phase-shift keying) modulation
- systematic polar codes for forward error correction
Pros:
Sending long messages/text is only seconds
Below is an example or receiving and transmiting.
