Which technology is commonly used in a Personal Area Network?

Bluetooth technology is a widely utilized standard for creating Personal Area Networks (PANs), which are intended for short-range communication typically within a range of about 10 meters. It enables devices such as smartphones, tablets, headphones, and wearable devices to connect and communicate wirelessly. This is particularly beneficial in scenarios where users want to pair devices for personal use, such as transferring files or streaming audio without the need for physical connections.

In contrast, the other options serve distinct purposes within different networking contexts. Ethernet cables are generally used in Local Area Networks (LANs) to provide wired connections and broader range connectivity. Fiber optic cables facilitate high-speed internet and data communication across much larger distances, commonly seen in backbone connections for network infrastructures. Satellite communication, while effective for connecting remote areas and enabling long-distance data exchange, does not fit the personal and localized nature of a PAN. Each of these technologies serves significant roles, but Bluetooth is specifically designed for the short-range, personal connectivity that defines a Personal Area Network.
