In a significant advancement for the Internet of Things (IoT), Sony Semiconductor Israel has introduced its vision for enhanced Reduced Capability (eRedCap), marking a pivotal shift in connectivity solutions. This initiative aims to address the evolving needs of manufacturers, operators, and technology suppliers as they adapt to the transition from legacy 2G and 4G infrastructures to more advanced networks. The move is expected to facilitate greater data flow necessary for next-generation artificial intelligence and industrial applications.
The launch highlights the urgency for robust, future-ready connectivity solutions as IoT device lifecycles extend into decades. Recent discussions surrounding eRedCap have primarily focused on technical specifications and early deployment phases, but details regarding product timelines and comprehensive industry strategies remain ambiguous. Previous announcements from Sony and other companies have pointed to the initial development of 5G-based IoT chips aimed at proof-of-concept rather than widespread adoption. Today’s announcement indicates a more mature roadmap that promises improved network consolidation and support for longer device lifecycles.
Understanding eRedCap’s Role in IoT
eRedCap is strategically positioned as a bridge between advanced 5G and low-power wide-area (LPWA) technologies. Sony emphasizes the significance of eRedCap’s balance between lower power consumption and higher data rates, making it suitable for a variety of applications, from industrial automation to AI-powered consumer wearables. This vision includes real-time connectivity, essential as the demand for efficient, data-heavy IoT applications continues to grow.
Telecommunications operators are currently evaluating the costs and complexities involved in maintaining parallel 2G, 4G, and 5G networks. Transitioning to eRedCap is expected to streamline these operations. According to Nohik Semel, CEO of Sony Semiconductor Israel, the gradual migration of legacy IoT devices will enable operators to phase out older networks and optimize valuable spectrum resources. He stated, “The future of IoT is clearly converging around eRedCap. It brings the performance needed for tomorrow’s connected devices while preserving the efficiency and longevity that industries count on.”
Innovations in the Altair ALT1550 5G Modem
As part of this initiative, Sony has announced the introduction of the Altair ALT1550 5G eRedCap modem. This new chip complies with 3GPP Release 18, features HD-FDD optimization for battery-powered IoT devices, and maintains backward compatibility with 4G Cat-1bis and LTE-M. Dima Feldman, Vice President at Sony Semiconductor Israel, explained that the development roadmap reflects a commitment to creating a cost-efficient and power-efficient solution designed for longevity: “Our Altair ALT1550 roadmap reflects our belief that 5G IoT must be cost-efficient, power efficient, and built for longevity. This is how we help customers transition smoothly from 4G to a sustainable 5G future.”
With HD-FDD technology preferred for its simplicity and reduced power consumption, Sony anticipates that eRedCap could achieve shipment volumes of 50 million units by 2030. This projection suggests a strong market readiness for large-scale transitions, especially in sectors where connectivity and real-time data flow are critical.
The commercialization of eRedCap illustrates how mid-tier cellular technology is becoming increasingly vital to IoT. Unlike high-end 5G or basic low-power solutions, eRedCap addresses a wide spectrum of device needs while helping operators manage costs and consolidate radio access technology. For businesses planning deployments that must last a decade or more, considering chip-level upgrades such as the Altair ALT1550 and proactively preparing for backward and forward compatibility can significantly reduce future redesign risks.
As more vendors and carriers invest in the eRedCap ecosystem, customers will have clearer options to achieve a balance between investment, performance, and lifecycle sustainability. The launch of eRedCap signals a new era in IoT connectivity, poised to drive innovation and efficiency across industries.
