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.
TECRA M4
Some computers in this series are equipped with
Bluetooth functions. Bluetooth wireless
technology eliminates the need for cables
between electronic devices such as computers
and printers. Bluetooth provides fast, reliable,
and secure wireless communication in a small
space.
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).
■
Theoretical maximum speed: 54Mbps
(IEEE802.11a, 802.11g)
■
Theoretical maximum speed: 11Mbps
(IEEE802.11b)
■
Frequency Channel Selection (5 GHz:
Revision A / 2.4 GHz: Revision B/G)
■
Roaming over multiple channels
■
Card Power Management
■
Wired Equivalent Privacy (WEP) data
encryption, based on 128 bit encryption
algorithm.
■
