Introduction
Wireless LAN
■
The numerical values for display are the theoretical maximums for
Wireless LAN standards. The actual values may differ.
■
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) standard. The actual transmission speed
will be lower than the theoretical maximum speed. To use the Atheros
SuperAG™ function, your client and access point must support the
corresponding feature. Performance of these functions may vary
depending on the format of data transmitted.

Some computers in this series are equipped with
a Wireless LAN mini-PCI card 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
(Revision A, B or G), and Turbo Mode. Refer to
Wireless LAN section in Appendix F.
