Which type of network is used for short-range communications, usually within a few feet?

A wide area network (WAN) spans large geographic areas and connects multiple local area networks (LANs). WANs are designed for long-distance communication and can cover extensive regions, often using leased telecommunication lines. This characteristic makes WANs unsuitable for short-range communications, as their primary function is to connect distant networks.

An extended area network (EAN) is designed to cover a larger area than a local area network but is not a standard term widely recognized in networking. While it may suggest connections beyond local range, it typically does not focus on short-range communications like those of a PAN. Therefore, EANs do not specifically cater to the needs of devices in close proximity.

A local area network (LAN) connects devices within a limited area, such as a home, school, or office building. While LANs can facilitate communication over a range of meters to hundreds of meters, they are not limited to the short distances characteristic of a personal area network, which usually operates within just a few feet.
