Samsung and MediaTek Test 5G RedCap for IoT Energy Efficiency

Samsung and MediaTek have achieved a significant milestone in the advancement of 5G technology by successfully testing 5G Reduced Capability (RedCap) over virtualized Radio Access Networks (vRAN). This collaborative effort was conducted in Samsung’s R&D lab in Korea, utilizing Samsung’s vRAN 3.0 software, OpenRAN-compliant radio, and MediaTek’s M60 modem-equipped RedCap testing platform. The primary objective of this trial was to confirm the effective integration of RedCap features with vRAN and Open RAN technologies, with a focus on enhancing energy-saving features.

Revolutionary Energy-Saving Features

One of the key themes of this breakthrough is the potential for extending battery life in IoT devices through the use of energy-saving technologies. Two standout features tested were Paging Early Indication (PEI) and extended Discontinuous Reception (eDRX). PEI works by reducing the frequency of device wake-ups, allowing devices to stay in low-power states longer by notifying them in advance about paging signals. This minimizes unnecessary energy consumption. On the other hand, eDRX enables devices to enter a sleep mode for extended periods, which can last up to three hours, further conserving battery power and improving longevity.

Implications for IoT and Network Efficiency

The successful integration and testing of these technologies signify a pivotal advancement in 5G connectivity, catering not just to higher data rates but also to power efficiency—a crucial factor for the widespread adoption of IoT devices. Eun Yong Kim, Vice President and Head of Air Technology at Samsung’s Networks Business, emphasized the importance of Samsung’s continuous advancements in 5G RedCap over the past year. These improvements have now culminated in effective trials of energy-saving features, reinforcing the broader objectives of extending battery life and reducing energy consumption in IoT ecosystems.

A Collaborative Leap Forward

Samsung and MediaTek have achieved a significant milestone in advancing 5G technology with their successful testing of 5G Reduced Capability (RedCap) over virtualized Radio Access Networks (vRAN). This collaboration took place at Samsung’s R&D lab in Korea, employing Samsung’s vRAN 3.0 software, an OpenRAN-compliant radio, and MediaTek’s M60 modem-equipped RedCap testing platform. The main goal of this trial was to confirm the seamless integration of RedCap features with vRAN and OpenRAN technologies, particularly aimed at boosting energy-saving capabilities. This achievement signifies a crucial step forward in the development of more efficient and flexible 5G networks.

As 5G technology continues to evolve, such innovations are essential in meeting the growing demands for higher performance, reduced latency, and improved energy efficiency. The successful integration demonstrated in this trial paves the way for the broader adoption of RedCap features in future 5G deployments, ensuring that both infrastructure and devices are optimized for next-generation connectivity.
