    - - enable seamless and convenient wireless communication between personal devices and within localized environments
        
        Short Range: WPANs operate over a short range, typically within a few meters to a few tens of meters. This limited range is intended to serve devices in close proximity.
        
        Low Power: Many WPAN technologies are designed to be energy-efficient, making them suitable for battery-powered devices and applications where conserving power is important.
        
        Personal Area: WPANs are often referred to as “personal” area networks because they are intended to serve the personal space of an individual. This can include communication between devices like smartphones, tablets, wearables, and other personal devices.
        
        Peer-to-Peer Communication: WPANs usually facilitate peer-to-peer communication between devices, allowing them to exchange data directly without the need for an intermediate infrastructure
  - - - a group of collocated computers or other devices that form a network based on radio transmissions (rather than wired connections)
    - - a quickly configurable type of network that doesn’t require physical equipment just to connect multiple devices with each other or over the internet
        
        Radio transmission: WLANs use radio waves to transmit data between devices instead of wires.
