As mobile networks move gradually from 4G to 5G, a new technology known as eRedCap is gaining attention as a way to connect everyday devices that need better performance without the cost and power use of full 5G, according to industry executives and analysts.
eRedCap, short for enhanced Reduced Capability, is part of global 5G standards and is designed mainly for connected devices rather than smartphones. These include industrial sensors, safety systems, wearables, tracking devices and emerging artificial intelligence-enabled products that need reliable and real-time connectivity over many years.
Today, many such devices still rely on older 4G networks or specialised low-power technologies that send only small amounts of data. However, as mobile operators plan the long-term shutdown of legacy networks, companies that design connected devices are looking for alternatives that can last for 10 to 20 years in the field.
Industry executives say eRedCap is intended to fill this gap. It offers higher data speeds and lower delay than older technologies, while remaining simpler and more energy-efficient than full 5G used in smartphones.
Nohik Semel, chief executive officer of Sony Semiconductor Israel, said device makers are increasingly planning for a future where 5G becomes the dominant network.
“For companies building connected devices that will be deployed for many years, the transition from 4G to 5G is unavoidable,” Semel said, adding that eRedCap is designed to make that transition practical.
Connected devices vary widely in their needs. Simple applications such as water meters or basic trackers may continue to use low-power networks that send very small amounts of data. In contrast, applications such as industrial automation, public safety equipment, smart wearables and AI-driven consumer devices require faster data transmission and real-time responsiveness.
eRedCap is aimed at these more demanding uses, where devices must handle voice, images or continuous data streams but still operate on batteries for long periods.
Another factor driving interest in eRedCap is the way mobile networks are managed. Telecom operators currently maintain multiple generations of networks at the same time, including 2G, 4G and 5G, which increases costs and consumes limited radio spectrum. By moving more devices onto 5G-based technologies such as eRedCap, operators can gradually simplify their networks.
The technology is defined under international standards and is not owned by any single company. Analysts say its adoption will depend on factors such as device cost, network support and the availability of compatible chips.
Mohit Agrawal, research director at Counterpoint Research, said interest in native 5G connectivity for devices is rising as businesses rely more on real-time data and edge computing.
“As companies increasingly use data and artificial intelligence to make decisions, having connected devices that can send and receive information in real time becomes more important,” Agrawal said.
Sony Semiconductor Israel said it is developing modem chips that support eRedCap as well as existing 4G networks, allowing device makers to move gradually rather than make an abrupt switch.
Industry experts say eRedCap is still at an early stage, but it is increasingly seen as a practical path for connecting millions of everyday devices in a future where 5G becomes the standard.
