DigRFSM v4 is intended to be used in mobile terminals that support next generation mobile broadband technologies such as Long Term Evolution (LTE) and Mobile WiMax. It also supports existing 3GPP standards such as 2.5G and 3.5G (EGPRS, UMTS, HSPA, etc) and due to its large data rate and scalability it is suitable to cover other non 3GPP air interfaces. All the standards discussed are supported over a common interface.

The MIPI Alliance Specification for DigRFSM v4 focuses on the protocol and the programming model as well as parts of the physical interface between the BBICs and RFICs. It does not prescribe anything within either IC, except for the minimum necessary to ensure compatibility at these layers. Additionally, it does not specify how multiple ICs, if available, should be used to support a particular standard. However, where necessary, additional text has been added to ensure there is a standardized interpretation of the specification. Details include definitions, timing diagrams, modes of operation, basic configurations and state diagrams. The intention is to leave designers the freedom to seek competitive advantage within the ICs, while ensuring that devices compliant with this specification can work together when correctly configured.
