NB-IoT from satellite brings standards-based low-power wide-area connectivity to devices anywhere on Earth - agriculture, logistics, environmental monitoring, maritime tracking. It is one of the most compelling applications of narrowband 5G NTN. It is also one of the most unforgiving environments for a physical layer, where devices operate at the absolute limits of link budget and power consumption.

NB-IoT satellite deployments demand FEC performance that can recover signals from devices transmitting at minimal power over long distances and degraded channels. The margin for error-correction inefficiency is effectively zero. Software-based implementations cannot deliver the sensitivity and reliability that operational IoT services require from orbit.

AccelerComm's LDPC and Polar IP cores provide the FEC foundation for NB-IoT satellite PHY designs, delivering the uplink sensitivity and BLER performance that mass IoT deployments demand. Combined with AccelerComm AX-RG for onboard processing applications, they give constellation operators and payload integrators a validated, standards-based Layer 1 for global IoT coverage.

KEY CHALLENGES

ACCELERCOMM SOLUTIONS

KEY CHALLENGE

  • NB-IoT devices transmit at very low power, placing extreme demands on uplink sensitivity and FECefficiency

ACCELERCOMM SOLUTION

  • AccelerComm's LDPC decoding delivers 1 dB uplink sensitivity improvement, directly extending the reach of low-power IoT devices over satellite links

KEY CHALLENGE

  • Error-rate performance must be maintained even at the margins of link budget where conventional FEC fails

ACCELERCOMM SOLUTION

  • Advanced decoding algorithms eliminate error-rate floors, ensuring reliable signal recovery at the sensitivity levels NB-IoT satellite deployments require

KEY CHALLENGE

  • SWaP-constrained satellite payloads cannot support software-based PHY at the scale of commercial IoT constellations

ACCELERCOMM SOLUTION

  • AccelerComm AX-RG delivers hardware-accelerated Layer 1 processing within the power and area constraints of space-grade satellite platforms

KEY CHALLENGE

  • Standards compliance across a rapidly evolving NB-IoT NTN specification is a programme-level requirement

ACCELERCOMM SOLUTION

  • 3GPP-aligned IP with an active NTN and 6G standards contribution roadmap — 55 international patents backing long-term standards alignment

KEY CHALLENGE

  • Serving millions of low-cost IoT devices requires maximum FEC efficiency to minimise infrastructure cost per connection

ACCELERCOMM SOLUTION

  • Hardware-optimised LDPC and Polar IP cores lower the cost-per-bit of IoT connectivity from orbit, enabling commercially viable mass-market deployments
