Personal Area Network Profile (PAN)

PAN describes how two or more Bluetooth enabled devices can form an ad-hoc network and how the same mechanism can be used to access a remote network through a network access point.

Usage Scenarios

A good example might be a group of PCs (or laptops) connecting wirelessly to one "master" PC, or Network Access Point. This will also allow for remote access of the "master" PC.

Example Products

Here are a few examples of the types of devices that you might find using the PAN:

  • Mobile Phone
  • PC
  • Laptop

Getting Technical

The PAN defines three roles, that of a Network Access Point (NAP), Group Ad-hoc Network (GN) and PAN User (PANU).

  • Network Access Point (NAP) and NAP Service – A Bluetooth device that supports the NAP service is a Bluetooth device that provides some of the features of an Ethernet bridge to support network services.
  • Group Ad-hoc Network (GN) and GN Service – A Bluetooth device that supports the GN service is able to forward Ethernet packets to each of the connected Bluetooth devices, the PAN users, as needed.
  • PAN User (PANU) and PANU Service - This is the Bluetooth device that uses either the NAP or the GN service.

The Baseband, LMP and L2CAP are the part of the Bluetooth protocols that reside in the OSI layers 1 and 2. SDP is the Bluetooth Service Discovery Protocol.

ME is the Management Entity which co-ordinates procedures during initialization, configuration and connection management.
