What is 5G RedCap?

5G RedCap briefly explained

5G RedCap, also known as 5G NR-Light, is a new software addition to 5G technology that has been specially developed for devices with lower performance requirements. The technology is designed to enable cost-efficient and energy-friendly connectivity for devices that do not require high data rates and where latency is less critical. These include smartwatches, wearables, but also industrial sensors or monitoring systems. By reducing the complexity of the devices used and extending battery life, 5G RedCap closes the gap between today's 4G networking and high-performance 5G applications in the IoT sector.

The advantages of 5G RedCap at a glance:

• Reduced costs: cheaper device production by reducing unnecessary 5G functions.
• Energy efficiency: Lower power consumption and longer battery life thanks to optimized data transmission.
• Medium data rates: 5G RedCap offers data rates in the medium range that are sufficient for many IoT applications without requiring the full range of 5G functions.

What distinguishes 5G RedCap from 4G?

4G vs. 5G RedCap: Compared to 4G, 5G RedCap offers improved efficiency that is better suited to the needs of IoT devices. The technology is ideal for applications that do not require the full functionality of 5G but want to access a similar range of services as LTE.

What distinguishes 5G RedCap from 5G?

5G vs. 5G RedCap: While 5G aims for maximum data rates and low latency, 5G RedCap focuses on providing sufficient connectivity for devices with lower requirements. It offers important benefits such as lower latency for IoT devices without putting excessive strain on the battery or driving up costs.

The compatibility of 5G RedCap

The software add-on is compatible with the normal 5G frequencies, so no new hardware is required. The end devices in use only require a 5G RedCap-capable radio module.

5G RedCap is interesting for these end devices:

5G RedCap is interesting for end devices that do not need to use the full functionality of 5G. These include

• Industrial sensors for data transmission from machines and systems
• wireless monitoring systems, such as health monitoring
• Smart grids, for monitoring traffic flows or controlling lighting
• Video surveillance for real-time transmission from security cameras
• Intelligent wearables, such as smartwatches

Outlook: 5G RedCap will become increasingly established

5G RedCap is currently the best choice for IoT devices when NB-IoT and LTE-M are too slow and 5G is too expensive. With more efficient utilization and reduced costs, 5G RedCap is a cost-effective solution for medium to high IoT applications that do not require the full bandwidth and speed of standard 5G. Therefore, the adoption of 5G RedCap devices is expected to increase over the next few years.
