Reduced Capability New Radio (NR-REDCAP), which will start to appear in 5G networks, will serve the market segment of “Smart IoT” applications. these are apps that require mid-range speeds that correspond to current LTE capabilities. This new 5G standard applies to devices such as wearables, industrial wireless sensors, and video surveillance. Interestingly enough, devices connected to the NR-REDCAP channels could enjoy similar bandwidth as a standard 4G LTE connection without adding a significant load to the network. The article below does an excellent job of describing exactly how NR-REDCAP works and the applications it supports.
Reduced Capability New Radio (NR-REDCAP) will address Mid-Speed Smart IoT applications with connectivity demands higher than LTE-M/NB-IoT can provide but not requiring critical IoT services such as mmWave or ultra-low latency.
Over the past few years, with the increasing demand for Low-Power Wide-Area Networks (LPWANs) for industrial applications, a couple of cellular-based technologies have emerged as the solution for many deployments: LTE CatM and NB-IoT.
