BBUs typically have multiple interfaces for connecting with other base station components, such as remote radio units RRU or antennas, transmission equipment, and control units. Baseband units often support multiple wireless standards, such as 2G, 3G, 4G LTE, and 5G, allowing operators to upgrade their networks and support different generations of wireless technologies. Baseband units are designed to accommodate the growth of network capacity, allowing operators to add or expand their base station resources as the demand for data and services increases.
