A base station is referred to a stationary trans-receiver used in telecommunications that serves as the primary hub for connectivity of wireless device communication. " A base station is called node B in 3G, eNB in LTE (4G), and gNB in 5G. The term is used in the context of mobile. In reality, a base station consists of several subsystems that must work together: the antenna-feeder system, the radio frequency unit, the baseband unit, and supporting infrastructure such as the tower, equipment room, power supply, and air conditioning. In the 4G era, the main hardware components were the BBU (baseband processing unit). The idea of base stations is anchored in their function to provide coverage, capacity, and connectivity, hence allowing for extending the working capabilities of mobile phones and other radio gear. It acts as a bridge, connecting your phone to a vast communication network to ensure.
