Regenerative Satellite Mesh – A (RSM-A) is an internationally standardized satellite communications protocol by Telecommunications Industry Association and European Telecommunications Standards Institute.
It is expected to be utilized by the Hughes Network Systems satellite called Spaceway-3.
The standard is meant to provide broadband capabilities of up to 512 kbit/s, 2 Mbit/s, and 16 Mbit/s uplink data communication rates with fixed Ka-band satellite terminal antennas sized as small as 77 cm.
The standard consists of the following documents: The standard describes the various segments involved in a RSM-A satellite system including: The uplink consists of a multi-frequency time-division multiple access (MF-TDMA) scheme where individual uplink spotbeams are assigned frequency channels out of the satellites frequency band.
Satellite Terminals transmit on timeslots on its uplink beam's frequency channels using mechanisms such as Bandwidth-on-Demand (BoD) protocols with the satellite payload.
