Wearable computer devices, including smart clothing and smart watches with accelerometers, can monitor daily activities and exchange digital information using the electrical conductivity of the human body as a data network. An example of a body area network is a medical sensor that has wireless connections implanted in the human body to monitor vital signs. With this network, communication takes place entirely within, on and in the immediate proximity of a person. Also referred to as a wireless body area network or a body sensor network, it's a type of mobile computer network that moves with a person and is typically established when a person connects their smartphone and Bluetooth headphone. The following are the most common examples:īody area network. Common use cases for a personal area networkĪ PAN has several use cases and applications.

These networks provide short connections between peripherals using wired technologies, such as USB, IEEE-1394 high-performance serial buses or a Thunderbolt hardware interface. A wireless PAN functions wirelessly and is carried over a low-powered, short-distance wireless network technology, such as Infrared Data Association (IrDA), wireless universal serial bus (USB), Bluetooth, ultra wideband or Zigbee.Ĭonceptually, the difference between a PAN and a wireless local area network ( LAN) is that the former tends to be centered around one person while the latter is connected without wires and serves multiple users. As such, limited distance, throughput, peripheral sharing and low volume are some of the main characteristics of this type of network. A wireless PAN is designed to serve a single person, SOHO or small workgroup. There are two types of PANs: wireless and wired.
