5G Non-Terrestrial Networks represent the next frontier of connectivity, bringing standards-based 5G coverage to areas that ground infrastructure cannot reach. But the physics of satellite communications create physical layer challenges that terrestrial 5G was never designed to solve. AccelerComm exists to solve them.

The 3GPP NTN standards define how 5G should work from orbit. What they do not do is make it easy. Doppler shift, propagation delay, power constraints, and thermal limits all place demands on the physical layer that software-based implementations cannot meet at the performance levels operators and primes require.

AccelerComm's IP is already proven in orbit on more than 100 commercial satellites, selected by major aerospace and satellite primes for programmes where physical layer performance is a programme-level requirement. From LDPC and Polar FEC to complete regenerative and transparent NTN PHY acceleration, AccelerComm provides the Layer 1 foundation that 5G NTN is built on.

KEY CHALLENGES

ACCELERCOMM SOLUTIONS

KEY CHALLENGE

  • Satellite channels introduce Doppler shift and propagation delays that degrade standard 5G PHY performance

ACCELERCOMM SOLUTION

  • AccelerComm's NTN-optimised IP is designed specifically for the impairments of satellite channels, maintaining performance where terrestrial implementations fail

KEY CHALLENGE

  • SWaP-constrained payloads cannot support software-based PHY processing at the throughput levels commercial services demand

ACCELERCOMM SOLUTION

  • Hardware-accelerated LDPC and Polar IP cores deliver up to 10x the performance of software alternatives within the power and area budgets of satellite payloads

KEY CHALLENGE

  • Error-rate floors in conventional FEC degrade service availability and increase retransmission overhead

ACCELERCOMM SOLUTION

  • Advanced, patented decoding algorithms eliminate error-rate floors, delivering ultra-low BLER across the full range of NTN channel conditions

KEY CHALLENGE

  • Achieving the link budget necessary for broadband services or small terminal support requires maximum FEC efficiency

ACCELERCOMM SOLUTION

  • AccelerComm's LDPC decoding unlocks 1 dB uplink sensitivity improvement, directly enabling higher capacity or smaller, lower-cost user terminals

KEY CHALLENGE

  • De-risking NTN PHY development against a rapidly evolving standards landscape

ACCELERCOMM SOLUTION

  • 3GPP-aligned, standards-based IP with a clear 6G NTN roadmap, backed by 55 international patents and active standards contribution
