Increasing complexity and flexibility of recent cellular technologies such as 5G require comprehensive design and testing of mobile devices. This white paper describes the lifecycle of a modern mobile device, which includes identification of target requirements and goals, real-estate planning of components, design, prototype development, testing of the device at various stages, and commercial launch.
Details of the smartphone components are given, covering human and machine interface components, internal components, radio technologies, and application technologies. Design and development of a mobile device are discussed, including collecting requirements, designing of chipsets, prototyping development, and commercial product development. Finally, various tests such as RF tests, protocol signaling tests, and application tests are discussed.
