Fast Ethernet LAN (100 megabits per second,
100BASE-TX).
Wireless LAN Some computers in this series are equipped with
a Wireless LAN module that is compatible with
other LAN systems based on Direct Sequence
Spread Spectrum/Orthogonal Frequency Division
Multiplexing radio technology that complies with
the IEEE 802.11 Standard.
■ The transmission speed over the wireless LAN and the distance over
which wireless LAN can reach may vary depending on surrounding
electromagnetic environment, obstacles, access point design and
configuration, and client design and software/hardware configurations.
The Transmit Rate (at X Mbit/s) is the theoretical maximum speed
under the IEEE802.11 (a/b/g/n) standards. The actual transmission
speed will be lower than the theoretical maximum speed.
