A Personal Area Network (PAN) allows communication between devices like phones, tablets, and computers. A wireless PAN (WPAN) uses wireless technologies like Bluetooth, Infrared, and WiFi to connect devices within 10 meters. Bluetooth creates small networks called piconets to connect keyboards, headsets, and other personal devices. Infrared uses invisible light to connect devices like phones and remotes. WiFi provides connections over larger areas of around 91 meters for sharing files between devices on a local network. WPANs offer simple setup between portable devices but have limited range and speeds compared to other wireless technologies.

2. What is Personal Area
Network(Pan)
 It is a computer network used for
communication among computerized
devices, including telephones and
personal digital assistants.
 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).

3. WPAN
 A wireless personal area network
(WPAN) is a PAN carried over wireless
network technologies such as IrDA,
Bluetooth, Wireless USB, Z-Wave,
ZigBee, or even Body Area Network.
 The reach of a WPAN varies from a few
centimeters to a few meters. A PAN may
also be carried over wired computer
buses such as USB and FireWire.

5. Wireless technologies used
for
WPAN:
Bluetooth
Infrared Data Association
Wi-Fi

6. Bluetooth
 A Bluetooth PAN is also called a piconet.
 Bluetooth uses short-range radio waves
over distances up to approximately 10
metres.
 A cable attached the antenna to a
Bluetooth card in a computer. They later
named the antenna "The BlueSniper.“
 Bluetooth devices such as a keyboards,
pointing devices, audio head sets,
printers, etc.

8. Infrared Data Association
 Infrared Data Association uses infrared
light, which has a frequency below the
human eye's sensitivity.
 It is used in cell phones and TV remote
ps3 controllers controls.
 Typical WPAN devices that use IrDA
include printers, keyboards, and other
serial data interfaces.

10. WiFi
 WiFi uses radio waves for connection
over distances up to around 91 metres,
usually in a local area network (LAN)
environment.
 Wifi can be used to connect local area
networks, to connect cellphones to the
Internet to download music and other
multimedia, to allow PC multimedia
content to be stream to the TV (Wireless
Multimedia Adapter), and to connect
video game consoles to their networks
(Nintendo WiFi Connection).

12. Advantages of WPAN
Dynamic network setup
Usually quick and relatively
simple to set up
WPAN enabled devices are
usually portable
Needs less technical skills to
deploy than LANs or WLANs.

13. Disadvantages of WPAN
 Typically have a limited range
 Currently limited to relatively slow data rates when compared
with WLAN technologies
 Compatibility and interoperability issues (WPAN technologies
are not usually compatible with each other. Some WPAN
technologies such as Bluetooth are known to have had
interoperability issues between devices from different
manufacturers.)
 As small devices that are often associated with WPANs often
have limited potential for adding extra hardware it is
sometimes difficult to find suitable upgrade equipment.
 Devices with inbuilt WPAN technologies can be considerably
more expensive than devices without WPAN technologies.
