A method to provide dedicated bandwidth, the method including: provisioning transmitters to transmit over a satellite link; generating, for each of the transmitters, a respective transmit signal using a common codeblock asynchronous sub-carrier multiple access (A-SCMA) encoding for a respective information stream; transmitting, via the satellite link, the respective transmit signal from each of the transmitters; and varying a bandwidth rate of each of the respective transmit signals with a grant-free protocol, where the bandwidth rate of the respective transmit signals is less than or equal to a maximum system rate, the transmitting of at least two or more of the transmitters is at least partially concurrent, and each of the respective transmit signals is modulated at a common frequency over a common frequency band with a common polarization. The method reduces latency, jitter, and provides dynamic bandwidth allocation without allocation feedback.
