What is PAN:

What is PAN A personal area network ( PAN ) is a computer network used for communication among computer devices, including telephones and personal digital assistants, in proximity to an individual's body. The devices may or may not belong to the person in question. The reach of a PAN is typically a few meters A personal area network (PAN) is the interconnection of information technology devices within the range of an individual person, typically within a range of 10 meters.

Types of PAN:

Types of PAN Wired PAN Uses wired devices, computer busses, such as USB and FireWire. Wireless PAN (WPAN) A wireless PAN consists of a dynamic group of less than 255 devices that communicate within about a 33-foot range. Unlike with wireless LANs, only devices within this limited area typically participate in the network, and no online connection with external devices is defined.

Wired PAN:

Wired PAN Used on just about any computer Busses Parallel Serial USB Designed for PC, and its peripherals Can be used for Smartphone, PDA’s, game consoles etc… FireWire Fast transfer of Data Ability for a lot of connections Not Mobile!!!

Wireless PAN history:

Wireless PAN history Developed by Thomas Zimmerman at M.I.T media lab late 1980’s Wanted to connect personal communication devices Increased efficiencies Reduce functional I/O redundancies Allow new conveniences and services Zimmerman and IBM Joined forces in 1995 Working on developing encrypted security system Free flowing information between devices and users

Types of WPAN:

Types of WPAN Z-wave Designed for home uses Low powered radio frequency Lighting, entertainment systems, home access IrDA Short distance data exchange with infrared light Cell phones, laptops, medical equipment Wireless USB Short range, high bandwidth radio communication Sends 480 Mbit/s up to 3m or 110 Mbit/s up to 10m Game controllers, flash drives, printers, scanners etc

Types of WPAN:

Types of WPAN Bluetooth Created in 1994 by Erickson Designed for wire free, short range communication Uses piconets to communicate Piconets Up to 8 devices One master and slave units Scatternet formed with multiple piconets through a common unit/device

WPAN Future:

WPAN Future Human body carries electrical signal Signal is low and unnoticeable by users Signal can carry data Information can be shared by users Electronic business cards Risk are obvious


Advantage/Disadvantage Advantages Mobile networks Easy flow of information Everything is at your fingertips Disadvantage Security
