Connectivity
WLAN
Wireless Local Area Network (WLAN) is a network
access technology becoming increasingly common
around the world. It allows users with portable
computers and wireless devices to access network
resources wirelessly, at the office, in the home, or in
public spaces (public Access Zones or so-called
“hot spots”) such as cafés, airports, aeroplanes
and hotels.
P990i WLAN may be used as an alternative to any
of the other types of network connection, such as,
USB, GSM, UMTS, Bluetooth™ connectivity or
infrared, and it may be chosen as the preferred
connection method for any of the P990i data appli-
cations.
The WLAN functionality is compliant with IEEE
802.11b (11 Mbps), and will work simultaneously
with the P990i GSM, UMTS, Bluetooth connectivity
and infrared interfaces.
The WLAN functionality can be switched on or off
as required, including when the P990i is placed into
flight mode.
The P990i allows the user to rapidly make a con-
nection to a public hot spot. A WLAN icon is per-
manently available on the P990i status bar and this
icon may be used to open the WLAN set-up
screen. The user may then turn on WLAN and scan
for available networks. A temporary connection to
a chosen hot spot may then be made without the
need for any technical details about the network.
It is important that data encryption can be used for
hot spot connection but the authentication and
association is open. It is possible to use WLAN in
conjunction with a personal firewall and virus scan-
ner.
For connection to a private network in the office or
home, security is very important. P990i will support
the following encryption/authentication methods:
• Shared (one or more WEP keys must be
selected).
• 802.1x.
• WPA and WPA2.
• WPA-PSK and WPA2-PSK
WPA2 and WPA2-PSK are supported for enter-
prise networks as well as open.
Setting up the infrastructure network mode is sim-
plified by the use of a wizard that presents relevant
options after each selection is made. For example
a WEP key selection screen follows the selection of
shared encryption.
Virtual private networks software is supplied for use
with the WLAN in infrastructure network mode.
Memory Stick Duo™ and
Memory Stick PRO Duo™
Memory Stick™ provides a convenient way of add-
ing storage and other functions to a wide range of
devices. P990i supports Memory Stick Duo™ and Memory Stick PRO Duo™. A 64 MB Memory Stick
PRO Duo is supplied with P990i and sizes of up to
32 GB are supported.
