November 3, according to Nokia Bell, in October this year, under the guidance of IMT-2020 (5G) Promotion Group, Nokia Bell completed the laboratory and field validation of 3GPP R17 RedCap key technology respectively.

The test followed the requirements of the "5G Enhanced Technology R&D Trial NR RedCap Key Technology Test Methodology" and "5G Enhanced Technology R&D Trial NR RedCap Field Performance Test Methodology" prepared by the IMT-2020 (5G) Promotion Group, and 100% of the mandatory functions passed. The test results prove that the network has the key functions of RedCap UE residency and access control, identification and random access, basic service-related functions, mobility and coexistence with Legacy UE, and the key indicators of single-user peak throughput, multi-point access and throughput, and user-plane delay under field conditions are in line with expectations, laying the foundation for the future commercialization of 5G RedCap.

RedCap devices are said to be designed for use cases that exceed the capabilities of large-scale IoT technologies such as LTE-M and NB-IoT, meaning they can support high data rates and low latency, with some representative use cases including

- Video transmission for traffic monitoring and security cameras

- Wearable devices such as smart watches, goggles, smart glasses, body health sensors and medical devices

- Industrial wireless sensors for temperature, pressure, proximity, smoke, liquid level and vibration

- Connected car applications such as infotainment, telematics, real-time HD mapping and software upgrades

- Drones for command and control and video transmission

The introduction of RedCap devices will help expand the IoT opportunities for operators, for example

- Expanding the IoT market for 5G NR by offering low-cost devices and enabling network software updates, leveraging existing networks

- Supporting the re-farming of LTE spectrum to NR by providing a cost-effective device solution for IoT service migration

- Delivering NR-based IoT solutions to complement URLLC components in Industry 4.0 for better integration and improved network efficiency.

Nokia Bell said it will continue to actively participate in the IMT-2020 (5G) Advancement Group's subsequent research and validation of 5G RedCap enhancement technologies.
