Personal Area Networks (PANs) are a type of computer network that links devices within a restricted area, typically within 10 meters (33 feet) of an individual person. They are designed to enable devices in a small office or home office (SOHO) environment to communicate and share resources, data, and applications. PANs are not contiguous networks as they are intended for individual usage and do not include a router, thus they cannot connect to the internet directly. However, a device within a PAN can be connected to a local area network (LAN) that then connects to the internet.

Wireless PANs (WPANs) are connected through signals such as Bluetooth, ZigBee, and Infrared
Wireless Personal Area Networks (WPANs) are a group of devices connected without the use of wires or cables. WPANs rely on short-range wireless connectivity protocols like Bluetooth, ZigBee, and Infrared.
Bluetooth is a computer networking protocol designed for short-range, low-power communications in the 2.4 GHz unlicensed band. It supports many devices, making it great for things like smart homes and healthcare. Bluetooth can connect up to 255 devices at once. It is perfect for various uses, from home automation to health tracking.
ZigBee is a short-range, low-power computer networking protocol that complies with the IEEE 802.15.4 standard. ZigBee devices operate in the 902-928 MHz and 2.4 GHz unlicensed bands. The technology is intended to be less complex and less expensive than other WPANs such as Bluetooth. ZigBee is great for healthcare because it works over longer distances.
Infrared Data Association (IrDA) uses infrared signals for short-range communication. Infrared communication is commonly used for the remote control of TVs and other home electronics.
WPANs are designed to serve a single person, SOHO, or small workgroup. They are characterized by limited distance, throughput, peripheral sharing, and low volume. WPANs can reach up to 10 meters and stand out for their convenience and easy setup. However, they tend to have slower data speeds, typically just a few megabits per second.
WPANs make it easy for devices to sync up. They are commonly used for health and fitness wearables, allowing users to track their activity and communicate with their phones wirelessly.

Wired PANs are connected through cables/wires such as FireWire or USB
A Personal Area Network (PAN) is a small network that interconnects technology devices within a limited range of just a few meters. While wireless communication is more common in PANs, they can also be wired. Wired PANs provide short connections between peripherals using wired technologies, such as USB, FireWire, IEEE-1394 high-performance serial buses, or a Thunderbolt hardware interface.
USB and FireWire technologies often link together a wired PAN. USB ports can be used to connect various devices to a computer, such as printers, webcams, or external hard drives. They are also used to charge smartphones and tablets. USB connections are also used to connect other devices, such as keyboards, barcode scanners, game consoles, and laptops.
FireWire is Apple's name for the IEEE 1394 High-Speed Serial Bus. It was developed by the IEEE P1394 Working Group, with contributions from Sony, Apple, Panasonic, and Philips, among others. FireWire can connect up to 63 peripherals in a tree or daisy-chain topology and allows peer-to-peer device communication. The copper cable used in its most common implementation can be up to 4.5m (15ft) long and is more flexible than most parallel SCSI cables.
Wired PANs provide a great option for connecting devices that are in the immediate vicinity of a user and their workspace. They are useful in home and office environments, providing flexibility and efficiency for short network ranges.

PANs are used in the Internet of Things, enabling communication between devices and components
A Personal Area Network (PAN) is a computer network that connects devices within a limited range of an individual person. The size of a PAN ranges from a few centimeters to a few meters. PANs are used in the Internet of Things (IoT) to connect devices within an individual's immediate vicinity, enabling communication between devices and components.
PANs are commonly used to connect devices such as smartphones, tablets, printers, keyboards, and other computerized devices. They can also be used for communication between personal devices or for connecting to a higher-level network or the internet. For example, a Bluetooth earpiece connecting to a smartphone is a common real-world example of a PAN. This type of network is often used in a small office or home office (SOHO) environment, where it can provide flexibility and efficiency in connecting devices.
PANs can be wireless or wired. Wireless PANs (WPANs) are the most common form of PAN for everyday use and are carried over a low-powered, short-distance wireless network technology such as Bluetooth, WiFi, IrDA, or Zigbee. WPANs use close-range wireless connectivity protocols and do not require the use of wires or cables. Devices connected through a WPAN communicate directly with each other, with one device acting as the master and the others as slaves.
Wired PANs, on the other hand, use wired technologies such as USB, FireWire, or IEEE-1394 high-performance serial buses to provide short connections between peripherals. PANs do not typically include a router and thus do not connect directly to the internet. However, a device within a PAN can be connected to a local area network (LAN) that then connects to the internet. For example, a desktop computer within a PAN can connect to a LAN and access the internet, while other devices in the PAN, such as wireless headphones, can connect to the computer but not directly to the internet.
