Samsung and MediaTek have successfully tested 5G Reduced Capability (RedCap) technology over virtualized Radio Access Networks (vRAN), potentially extending battery life for IoT devices. The trial was conducted in Samsung’s R&D lab in Korea and utilized Samsung’s vRAN 3.0 software, OpenRAN compliant radio, and MediaTek’s M60 modem-equipped RedCap testing platform.
The integration of RedCap features with vRAN and Open RAN was the focus of the trial, with a particular emphasis on energy-saving technologies such as Paging Early Indication (PEI) and extended Discontinuous Reception (eDRX). PEI notifies devices about paging signals in advance, allowing them to stay in a low-power state longer, while eDRX enables devices to enter sleep mode for extended periods, sometimes up to three hours.
Eun Yong Kim, Vice President and Head of Air Technology at Samsung’s Networks Business, highlighted the significance of this milestone. He noted that Samsung’s continuous advancements in 5G RedCap over vRAN since last year have now culminated in the testing of energy-saving features. This progress not only enhances 5G connectivity but also broadens the IoT ecosystem by reducing energy consumption and associated costs.
HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek, emphasized the impact of this collaboration on the 5G RedCap industry. He stated that the successful test builds market confidence in transitioning from legacy connectivity to the new standard, opening up new opportunities for IoT application developers.
Samsung plans to make its RedCap technology available this year for both traditional RAN and vRAN, with intentions to integrate it into Tier 1 operators’ networks. This advancement in energy-saving technology has the potential to improve the performance and efficiency of IoT devices, ultimately benefiting consumers and developers in the industry.
In summary, Samsung’s ongoing research on 5G Reduced Capability technology has led to successful testing over virtualized Radio Access Networks (vRAN), which could lead to an extension of battery life for IoT devices by utilizing energy-saving technologies like Paging Early Indication (PEI) and extended Discontinuous Reception (eDRX). The successful test builds market confidence for transitioning from legacy connectivity to new standards while opening up new opportunities for IoT application developers.
