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. 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. To make this clearer, consider a simple. With the rise in data traffic and continuous innovations in wireless technology, base station design has become a cornerstone in ensuring that networks are efficient, reliable, and scalable. " A base station is called node B in 3G, eNB in LTE (4G), and gNB in 5G.
