RAN
RAN (Radio Access Network) is the part of a mobile phone network that connects phones and other wireless devices to the main network. Think of it like the local roads that connect houses to highways - it's the critical infrastructure that lets mobile devices communicate with cell towers. When you see cell towers or small antenna boxes on buildings, those are parts of the RAN. This term often appears in job descriptions for roles involving mobile network planning, deployment, and maintenance. Some other names for this are "wireless network" or "mobile network infrastructure."
