To address the contradiction between the cost of 5G terminals and the widespread adoption of applications, 3GPP proposes RedCap technology, a lightweight version of 5G. Typical application scenarios for RedCap include industrial wireless sensors, video surveillance, and wearable devices. With the freezing of R17, the large-scale development and application of RedCap have become urgent. This paper first introduces the key technologies and application scenarios of RedCap and calculates the theoretical peak date rates of RedCap across different frequency bands. Subsequently, based on base station (BS) hardware, the development and implementation of the RedCap protocol are discussed, providing strategies for access network and core network upgrades during RedCap deployment. Finally, the paper presents the integrated applications of 5G RedCap in various sectors.

摘要

To address the contradiction between the cost of 5G terminals and the widespread adoption of applications, 3GPP proposes RedCap technology, a lightweight version of 5G. Typical application scenarios for RedCap include industrial wireless sensors, video surveillance, and wearable devices. With the freezing of R17, the large-scale development and application of RedCap have become urgent. This paper first introduces the key technologies and application scenarios of RedCap and calculates the theoretical peak date rates of RedCap across different frequency bands. Subsequently, based on base station (BS) hardware, the development and implementation of the RedCap protocol are discussed, providing strategies for access network and core network upgrades during RedCap deployment. Finally, the paper presents the integrated applications of 5G RedCap in various sectors.
