Radisys and AccelerComm Enhance Satellite 5G NTN for IoT and Broadband Services
Key Highlights
-
The companies integrated NB-IoT NTN into an existing 5G NR-NTN RAN solution.
-
The unified platform supports both NB-IoT (massive IoT) and NR-NTN (broadband) services.
-
Satellite Network Operators (SNOs) can use existing 5G NR-NTN spectrum to support low-power NB-IoT devices.
Radisys Corporation and AccelerComm announced an expansion of their ongoing 5G Non-Terrestrial Network (NTN) collaboration. The companies have integrated NB-IoT NTN capabilities into an existing NR-NTN RAN solution.
The combined solution enables NTN providers and Satellite Network Operators (SNOs) to deliver satellite connectivity to low-power NB-IoT devices using spectrum already allocated for 5G NR-NTN broadband services. The pre-integrated software is designed to support both transparent and regenerative payload deployments, providing flexibility across current and emerging markets.
NB-IoT NTN is designed to enable power-efficient, cost-effective, and scalable IoT services. Potential use cases include infrastructure monitoring, emergency communications, maritime connectivity, logistics, and related applications.
Key Capabilities:
-
3GPP Release 18 NB-IoT and Release 19 NR-NTN support.
-
Regenerative and transparent mode support, deployable over LEO, GEO, and HAPS platforms.
-
CPC IoT with anchor and non-anchor carrier support.
-
Band and bandwidth support:
-
NB-IoT: S/N band and 180 kHz bandwidth with 15/3.75 kHz SCS.
-
NR: S/K, Ku, and Ka bands and bandwidth from 3 to 400 MHz.
-
-
Support for extended Discontinuous Reception (eDRX).
-
Mobility features including service link switchover and conditional handover (Release 18).
-
NB-IoT features including SIB-NB 31, SIB-NB 32, HD-FDD downlink and uplink support.
According to company representatives, the integration expands existing NB-IoT NTN RAN software capabilities alongside established NR-NTN functionality, creating a unified NTN solution that supports both deployment modes. The companies state that this approach is intended to help customers deliver a range of 5G services to satellite operators, mobile network operators, enterprises, and industry sectors.
The companies also noted that delivering NB-IoT alongside broadband services over satellite requires efficient use of power, spectrum, and latency resources. By combining physical layer technology with RAN software, the solution is designed to enable satellite operators to support both IoT and high-throughput services within a 3GPP-compliant framework.
