Sony Semiconductor Israel introduced its long-term roadmap for 5G IoT with the Altair ALT1550, a 5G eRedCap modem designed for battery-powered, long-life connected devices. The company positioned eRedCap, or enhanced Reduced Capability, as the sweet spot between full 5G NR and narrowband IoT for industrial and consumer applications that need more bandwidth without high complexity. This approach addresses use cases ranging from industrial automation to AI-enabled wearables that demand real-time, low-power connectivity.
The ALT1550 is based on 3GPP Release 18 and supports eRedCap with HD-FDD operation, simplifying radio design and helping reduce power consumption. It also supports 4G Cat-1bis and LTE-M, enabling deployment on today’s LTE networks while preparing devices for native 5G. Sony noted that the modem is already in advanced real-silicon testing, aligning with operators’ plans to phase out legacy 2G and 4G infrastructure.
For IoT device makers, this modem roadmap offers a practical migration path from LTE to 5G while preserving battery life, coverage, and unit economics. Industries deploying devices expected to operate for 10–20 years can maintain long-term connectivity without overbuilding on full 5G hardware. As AI-driven analytics and edge processing expand, this middle-tier 5G option supports richer data streams and voice where needed while keeping costs in check, signaling a growing segment of efficient, future-ready IoT modules.
