In the realm of IoT, the promise of ubiquitous connectivity has always been a driving vision. As the world continues to embrace 5G technology, the integration of satellite communications as defined by the 3GPP Release 17 standards marks a significant leap towards achieving this vision. The convergence of terrestrial and non-terrestrial networks (NTN) holds immense potential for providing seamless, cost-efficient, and widespread connectivity, particularly in areas where traditional cellular networks fall short.
Expanding Horizons with Satellite NTN
Understanding Satellite Connectivity
NTN encompasses all forms of network communications that are not earth-bound, including satellite systems that can provide cellular network-like services directly from space. In 3GPP Release 17, two main satellite orbits are specified for NTN IoT connectivity: Low Earth Orbit (LEO) and Geostationary Equatorial Orbit (GEO).
- LEO Satellites: Positioned closer to the earth (400-2,000 km altitude), LEO satellites provide lower latency and high-resolution imaging. These satellites are ideal for rapid data transfer and applications requiring quick response times.
- GEO Satellites: Orbiting at a much higher altitude (35,780 km), GEO satellites offer wider coverage but with higher latency. They are better suited for continuous, real-time monitoring across vast areas.
As we venture into this new era, NTN represents a pivotal advancement, extending reliable connectivity far beyond the reach of traditional cellular towers.
3GPP Release 17 and the Role of NTN
The 3GPP Release 17 by the Global System for Mobile Communications Association (GSMA) marks a significant milestone. For the first time, this standard enables devices designed for cellular networks to access satellite communications using a standardized approach, including NR-NTN for 5G New Radio and IoT-NTN for LPWA IoT applications via NB-IoT and LTE-M. This development promises ubiquitous coverage, effectively filling persistent gaps in cellular network reach, particularly in rural and remote regions.
Bridging the Gap: Terrestrial vs. Satellite IoT Ecosystems
Cellular IoT applications traditionally accustomed to high data throughput and lower costs will encounter higher costs per megabyte and significantly lower throughput in satellite communications. Applications must be optimized to function efficiently within these constraints, focusing on transmitting critical data in smaller packets. On the other hand, adding satellite will enable dual-mode connectivity, which can help mitigate these issues by leveraging cellular networks where available and only switching to satellite networks when necessary.
Conversely, IoT applications that are already using satellite communications will experience unprecedented benefits. The integration with 5G allows for the use of standardized, off-the-shelf cellular modules, antennas, and protocols, reducing the need for bespoke, high-cost solutions. This not only lowers development and deployment costs but also accelerates time-to-market for new IoT solutions.
Velocity IoT’s Dual-Mode Connectivity: A Seamless Transition
Velocity IoT, in partnership with Skylo, a leading satellite NTN provider, and floLIVE, a global connectivity and network infrastructure leader, will soon offer satellite NTN service as an additional IMSI on our multi-IMSI SIM. This innovation will be available on multiple form factors including eSIM, allowing customers to leverage both satellite and cellular networks using a single SIM, module, and antenna. Velocity IoT customers using Release 17 modules can benefit from this service with a simple OTA update to their current SIMs, ensuring a seamless transition to dual-mode connectivity.
Such dual-mode connectivity ensures that IoT devices can select the optimal network based on location, cost, and capability, thereby eliminating coverage gaps and enhancing operational efficiency. This advancement supports industries with critical connectivity needs, ensuring seamless operations even in the most remote and challenging environments.
Practical Applications: Transforming Industries with Satellite IoT
With vast geographical areas lacking cellular coverage, many remote use cases can benefit from the extended reach provided by satellite connectivity.
Asset Tracking and Location
For industries dependent on asset tracking, such as logistics and transportation, the extended coverage provided by satellite communications ensures uninterrupted tracking of goods, even in the most remote locations. This level of visibility is crucial for supply chain optimization and timely delivery.
Industrial IoT and Equipment Monitoring
In sectors like mining, oil and gas, and heavy machinery, continuous monitoring of equipment health and performance is essential. Satellite NTN facilitates reliable data transmission from equipment in remote and challenging environments, preventing downtime and optimizing maintenance schedules.
Lone-Worker Safety
Ensuring the safety of lone workers in remote areas is a top priority for many industries. Satellite connectivity ensures that safety devices remain connected, allowing for real-time monitoring and emergency response, regardless of the worker’s location.
Tool and Equipment Tracking
In construction and field services, the ability to track and manage tools and equipment across widespread sites enhances asset utilization and reduces losses. Satellite IoT solutions provide the necessary coverage to track these assets effectively.
The Road Ahead: Transformative Impact on the IoT Landscape
Disruptive Potential and Market Trends
The introduction of satellite NTN for IoT is set to be highly disruptive, particularly for incumbent satellite network operators. The ability to integrate seamlessly with 5G networks broadens the market and enhances the capabilities of satellite IoT service providers. However, cellular-based IoT users may experience initial disillusionment due to the higher costs and lower bandwidth associated with satellite communications.
A Strategic Vision for the Future
As the need for connecting remote assets to backend systems grows, the demand for edge intelligence and comprehensive connectivity solutions will continue to drive innovation.
