| PAN |
A Personal Area Network typically covers the few
meters surrounding a user's workspace and provides the ability
to synchronize computers, transfers files and gain access to
local peripherals like printers and a range of pocket hardware.
A technology like Bluetooth may enable wireless PAN. |

network, in which long messages are subdivided into short packets
and routes to its final destination. |

| PCS |
Personal Communications Services. Any of several
types of wireless, voice and/or data communications systems,
typically incorporating digital technology. PCS licenses are
most often used to provide services similar to advanced cellular
mobile or paging services. However, PCS can also be used to
provide other wireless communications services, including services
that allow people to place and receive communications while
away from their home or office, as well as wireless communications
to homes, office buildings and other fixed locations. |

| PIM |
Personal Information Management functionality
started with the Filofax, with all your personal data held in
paper form in a single package. The personal organiser came
along to store the data electronically with the ability to store
thesame information on your PC and synchronise the two. The
same functionality is now finding its way into mobile phones,
which also have the synchronisation capability. |

| PSD |
Packet Switched Data is a technology where the
communication “pipe” is shared by several users, thus making
it very efficient. The data is sent to a specific address with
a short delay. This delay depends on how many users are using
the pipe at any one time as well as the level of priority requested
for your information. Charging is made according to the volume
of data and not the duration of the connection. PSD is the technology
used for data communication across the internet and because
it maximises the use of the network, this type of communication
will eventually be used even for voice communication, with a
high level of priority assigned to that form of traffic. |
