• E.g. microwave antenna on a TV news van, extended high in the air, beaming video and sound back to the main TV studio.

WAN:

• A WAN (Wide Area Network or extended network) connects multiple LANs to one another over great geographic distances.
• WANs operate using routers, which can "choose" the most appropriate path for data to take to reach a network node.
• E.g.: Internet

PAN:
