A PAN (Personal Area Network) is a network that connects digital devices and communication equipment in the immediate vicinity of a person. It is a wireless or wired network that is limited to a very small physical area and typically has a radius of 10 meters or less.
Structure and Functionality
A PAN networks devices such as laptops, smartphones, or wireless peripheral devices, for example, a mouse with a computer. PAN networks facilitate wireless data transmission, data exchange, and resource sharing between connected devices.
Technologies for PANs include Bluetooth, Infrared (IrDA), WLAN/Wi-Fi, and USB.
Advantages of a PAN
- Easy setup: Connecting devices in a PAN is uncomplicated and quick, without requiring complex network components such as routers or switches.
- High security: The limited range of the network increases security, as only devices in close proximity can communicate with each other.
- Low energy consumption: PANs have low energy consumption, making them ideal for operation with batteries or rechargeable batteries.
- Mobility: PANs promote mobility, as the connected devices can be easily transported and flexibly deployed.
Application examples
A common example is the connection of peripheral devices such as mice, keyboards, or printers to computers. Similarly, a PAN enables quick and easy data transfer between mobile devices like smartphones and tablets, often using Bluetooth. Additionally, temporary ad-hoc networks can be set up to exchange data between devices without requiring a fixed infrastructure.
