What is Personal Area Network (PAN)?
It is a network used to establish communication between computer devices. These are devices that are close to the user, such as phones, personal digital assistants, etc. These devices may or may not belong to the user in question. The range of a PAN is a few meters. In addition to enabling personal devices to communicate with each other, PAN can also be used to connect to the Internet or a high-level network. Personal area networks can be wired using data pathways such as USB and FireWire. A wireless personal area network can also be established using network technologies such as IrDA, Bluetooth, UWB, Z-Wave, and ZigBee.
A group of up to 8 devices in a master-slave relationship is called a piconet in a Bluetooth PAN. The first Bluetooth device connected to a piconet becomes the master, and all other devices communicating with this device become slaves. Although the average range of a piconet is 10 meters, under ideal conditions, this range can extend up to 100 meters. With the latest innovations, Bluetooth antennas have been designed to allow for exceeding these mentioned ranges. At DEF CON 12, a group of expert programmers known as "Flexilis" connected two Bluetooth devices to each other from a distance of more than 800 meters using a combination of antennas, including telescopic and Yagi antennas, all mounted on a +++++ pole. The antenna was connected to the Bluetooth card in the computer via a cable, and they named this setup "BlueSniper."
Skinplex is another PAN technology that enables transmission over a capacitive field close to the human skin. With Skinplex, devices more than a meter away from the human body can still be detected and communicate. This technology is currently being used in the control of door locks and parasitic protection systems of convertible vehicles.
