It is primarily used for personal devices like smartphones, laptops, tablets, smartwatches, printers, and other gadgets, enabling them to communicate with each other. 🔹 Key Characteristics of PAN Geographical Scope: Very short range (usually < 10 meters). Ownership: Fully personal and user-managed. Data Transfer Speed: Varies — from a few Kbps (classic Bluetooth) to over 24 Mbps (Bluetooth 5.0+). Connectivity Medium: Primarily wireless (Bluetooth, IR, ZigBee); sometimes wired (USB). Use Case: Connecting personal devices like smartphones, tablets, headsets, smartwatches, laptops. 🔹 Types of PAN 1. Wired PAN (WPAN) A Wired Personal Area Network (WPAN) uses physical cables to connect devices. The most common example is a USB (Universal Serial Bus) network, which connects devices like printers, storage devices, and audio systems to computers. ...
