A personal area network (PAN) is a computer network used for the transmission of data between devices such as computers, telephones, tablets and personal digital assistants. PANs can be used to communicate between personal devices themselves (interpersonal communication), or to connect to a top-level network and the Internet (a uplink) where a "master" device assumes the role of Internet router. A wireless personal area network (WPAN) is a low-power PAN transported through short-range wireless network technology such as:
• INSTEON
• IrDA
• Wireless USB
• Bluetooth
• Z-Wave
• ZigBee
• Body Area Network
The range of a WPAN ranges from a few centimeters to a few meters. A PAN can also be carried via computer cabling such as USB and FireWire. Although a Wi-Fi anchor connection (secure) could be used by a single user, it is not considered a PAN.
A wireless personal area network (WPAN) is a personal area network - a network for interconnecting devices centered on a person's workspace - where the connections are wireless. The wireless PAN is based on the IEEE 802.15 standard. The two types of wireless technologies used for WPAN are Bluetooth and the association of infrared data.
A WPAN could serve to interconnect all the ordinary computing and communication devices that many people have on their desk or carry with them today; or could serve a more specialized purpose, such as allowing the surgeon and other team members to communicate during an operation.
A key concept in WPAN technology is known as "connect." In the ideal scenario, when two devices equipped with WPAN are close (a few meters away) or within a few kilometers of a central server, they can communicate as if they are connected by a cable. Another important feature is the ability of each device to selectively block other devices, avoiding unnecessary interference or unauthorized access to information.
The technology for WPANs is in its infancy and is undergoing rapid development. The proposed operating frequencies are around 2.4 GHz in digital modes. The goal is to facilitate seamless operation between devices and home or business systems. All devices in a WPAN can be connected to any other device in the same WPAN as long as they are within the physical range of the other. In addition, WPANs around the world will be interconnected. For example, an archaeologist in Greece could use a PDA to directly access the University of Minnesota databases in Minneapolis and transmit the results to that database.
