5G, the key infrastructure for the digital transformation of economy society, has been widely integrated into various industries in the past four years. However, as 5G application going deeper, the higher cost of 5G terminals brings the challenges for the large-scale deployment of 5G applications. 5G RedCap (Reduced Capability), also was known as “NR Light”, can obtain the advantages of low cost and low power consumption by reducing terminal complexity, fully enabling the mid- and high- speed Internet of Things (IoT) scenarios and further promoting the large-scale deployment of 5G applications. ZTE launched the comprehensive "Basic + Enhanced + Overlay" RedCap solution that can flexibly match the deployment stage and diverse scenarios, helping RedCap evolve from "usable" to "useful".
