Why is RedCap Needed?
While we explained the need for RedCap from high requirements view, there are several reasons why RedCap is needed from an
infrastructure and operator’s point of view.
It is important to note that while 5G networks are being deployed globally as shown in Figure 1, they are not all the same 5G
network types. There are two distinct 5G network types: Stand Alone (SA) and Non-Stand Alone (NSA). The SA networks rely
completely on 3GPP 5G specifications for all device and infrastructure equipment. NSA networks rely on both 3GPP 4G and 5G
specifications. This means that “SA only” devices are specifically designed for 5G networks, and do not support 4G technologies
such as LTE-M and NB-IoT. This can be a problem for operators of pure green-field 5G networks (no legacy 4G installations) and
regional mandates for devices to support SA if they want to satisfy IoT requirements.
