Complete 5G NR Physical Layer
Challenges of 5G Non-Terrestrial Networks
As the 3GPP standards for 5G Non-Terrestrial Networks (NTNs) evolve, and the industry looks to diverse use cases such as Broadband, Direct to Device (D2D), Direct to Vehicle (D2V) and defense applications it is clear that the next generation of constellations will be best served by regenerative architectures. This architecture brings significant performance benefits, but creates a number of technical challenges.
Regenerative satellites require a large amount of real time signal processing to be carried out in the payload, which effectively becomes a base station in space. The onboard environment of a satellite brings with it requirements that are very different from those in which terrestrial base stations operate. In particular, Size, Weight, and Power (SWaP) are all tightly constrained.
As well as the demanding environmental requirements, the nature of the signal processing required also looks very different to that of a terrestrial base station. 5G NTN signals with very high path loss, latency and Doppler shift present different challenges to signals in dense urban terrestrial applications.
AccelerComm has developed a range of flexible physical layer (PHY) solutions for 5G regenerative NTN constellations that directly address the unique challenges of this environment, drawing on our many years of experience with advanced algorithms and innovative implementation.
Out of the Lab and into Space
Designed for commercial applications our solutions are specified to deliver up to 6Gbps while supporting 128 beams and 4,096 users per chipset, which can be scaled to meet the capacity requirements of the next generation of constellations.
