NodeB
NodeB is a term used in mobile phone networks, specifically in 3G technology. Think of it as a smart antenna tower that connects mobile phones to the main network. It's similar to what people commonly call a cell tower, but specifically for 3G networks. When you see this term in a resume, it usually means the person has experience working with mobile network equipment and infrastructure. While newer technologies like 4G (eNodeB) and 5G (gNodeB) exist, many networks still maintain NodeB equipment, making this experience valuable. This equipment plays a crucial role in keeping mobile phones connected to the network.
