Wireless LAN Connection (on selected models)
The optional built-in wireless LAN is a compact easy-to-use wireless Ethernet adapter. Implement-
ing the IEEE 802.11 standard for wireless LAN (WLAN), the optional built-in wireless LAN is
capable of fast data transmission rates using Direct Sequence Spread Spectrum (DSSS) and Or-
thogonal Frequency Division Multiplexing (OFDM) technologies on 2.4GHz/5GHz frequencies.
The optional built-in wireless LAN is backward compatible with the earlier IEEE 802.11 standards
allowing seamless interfacing of wireless LAN standards.

Access (WPA) features.
Ad-hoc mode
The Ad-hoc mode allows the UltraMobilePC
to connect to another wireless device. No
access point (AP) is required in this wireless
environment.
(All devices must install optional 802.11 wire-
less LAN adapters.)
Infrastructure mode
The Infrastructure mode allows the UltraMo-
bilePC and other wireless devices to join a
wireless network created by an Access Point
(AP) (sold separately) that provides a central
link for wireless clients to communicate with
each other or with a wired network.
(All devices must install optional 802.11 wire-
less LAN adapters.)
