MIPI Alliance develops interfaces that define the signaling characteristics, protocols and other techniques used to interconnect components in a device and enable the components to interoperate and communicate with one another. A device can use a few or multiple interfaces. In a mobile device such as a smartphone, a range of interfaces is needed to connect a couple dozen components, from the antenna, modem and application processor to the microphone, speaker, battery, camera, sensors and others. Devices designed for mobile-influenced applications, such as wearables or automobiles, will use varying numbers and types of interfaces depending on the application and components used.
