CPRI is the abbreviation of Common Public Radio Interface, a standardized communication protocol widely adopted in mobile communication base stations. CPRI plays the role of transmitting baseband I / Q signals to radio units in traditional BS (base station). CPRI has efficient and flexible I / Q data interfaces for various standards, such as GSM, WCDMA, LTE, etc. Unlike the data center, the CPRI o...
