  Personal area network - Wikipedia, the free encyclopedia
A personal area network (PAN) is a computer network used for communication among computer devices (including telephones and personal digital assistants) close to one person.
PANs can be used for communication among the personal devices themselves (intrapersonal communication), or for connecting to a higher level network and the Internet (an uplink).
Personal area networks may be wired with computer buses such as USB and Firewire.

 Local area network - Wikipedia, the free encyclopedia
A local area network (LAN) is a computer network covering a local area, like a home, office or small group of buildings such as a college.
A layout known as a spanning tree protocol is often used to maintain a loop free network topology within a LAN, particularly with ethernet.
LANs are distinguished from other kinds of networks by three characteristics: (1) their size, (2) their transmission technology, and (3) their topology.

 Personal Area Networks: Near-field intrabody communication
In Figure 2 the PAN transmitter is modeled as an oscillator, and the receiver is modeled as a differential amplifier.
A communication network is judged primarily by channel capacity, with a theoretical limit defined by the Hartley-Shannon law [5] C = Blog(1 + S/N), where C is channel capacity in bits/second, B is bandwidth, S is signal, and N is noise.
When the woman and man depicted in the figure are in close proximity, particularly when they shake hands, an electric circuit is completed, allowing picoamp signals to pass from the transmitter through her body, to his body, to the receiver by his foot, and back through the earth ground.

To develop such personal area networks, or PANs, Almaden scientist Thomas G. Zimmerman developed technology that, in effect, transforms the human body into a copper cable.
As part of a PAN, a person would be instantly known to properly equipped cars or telephones, eliminating the need for keys or coins.
On the back of the PAN devices are metal plates, one of which must face the body while the other faces outward to establish a ground connection with the earth.

For example, a person traveling with a laptop, a personal digital assistant (PDA), and a portable printer could interconnect them without having to plug anything in, using some form of wireless technology.
Also see wireless personal area network (WPAN) which is virtually a synonym since almost any personal area network would need to function wirelessly.
Conceptually, the difference between a PAN and a wireless LAN is that the former tends to be centered around one person while the latter is a local area network (LAN) that is connected without wires and serving multiple users.

The cellular network was a natural extension of the wired telephony network that became pervasive during the mid-20th century.
Coverage of a large area was allowed through the definition of relatively small (1 to 2 km diameter) "cells" that cooperate with their like neighbors to create a seemingly seamless network.
These "local area" networks were needed to maintain connectivity with the wired data network of the enterprise in a way that was analogous to the need for extending the voice network for the mobile user.

 Extension of Bluetooth Personal Area Network across an Internet Communications Session
A wireless personal area network is one kind of local area network that can interconnect all devices supporting wireless capabilities in a short-range area by using wireless technology such as Bluetooth.
Potential needs exist for communication between one device in one wireless personal area network and another device in another wireless personal area network across an existing network, and this communication can be conducted along with a voice, video, or Instant Messaging session.
The end points may support a wireless personal area network like Bluetooth, so that the end effect is the extension of the wireless personal area network across the Internet in a controlled and managed manner.
