This whitepaper introduces 5G Reduced Capability (RedCap), a new technology standardized in 3GPP Releases 17 and 18. RedCap enables simpler, lower-power 5G devices for industrial IoT. It highlights key use cases such as wearables, sensors, and video surveillance, and explains how RedCap reduces device complexity, extends battery life, and unlocks new industrial applications.
Executive Summary
3GPP has introduced the RedCap feature set to enable user equipment (UE) with reduced complexity and power requirements, targeting IoT and industrial applications that do not need the full capabilities of traditional 5G devices. RedCap represents a new class of 5G-only technology designed to unlock new use cases in high-density, cost-sensitive, and space-constrained environments.
• RedCap simplifies 5G devices by reducing bandwidth, antennas, modulation, and duplexing complexity while preserving essential 5G benefits.
• Power-saving features, including extended sleep cycles and relaxed measurement requirements, significantly enhance battery life.
• RedCap is suited to industrial scenarios such as wearables, wireless sensors, video surveillance, handheld radios, and mobile trackers.
• Adoption requires network upgrades to 5G standalone (SA) operation and software updates.
• While offering lower cost and complexity, RedCap devices still meet the performance demands of many industrial applications.
The purpose of this whitepaper is to provide an industrial perspective on RedCap and help stakeholders understand its relevance, implementation considerations, and potential impact. By reducing device and network complexity and costs, RedCap makes 5G more accessible for massive IoT deployments, supporting innovation in smart factories and other industrial environments.
