have an effect on the range. Decisive is frequently an optimal placement of
the radio stations (both network adapters and base stations).
1.5 The AirLancer 54 models
The AirLancer series with 54 Mbps data transfer rate features several mod-
els. You have the possibilty to extend standard PCs and a multitude of mobile
computers for access to the Wireless LAN:
•
AirLancer MC-54ag
Dual band PC card (Cardbus) according either to IEEE 802.11a (up to 54
Mbps data tranfer rate in the 5 GHz band) or to IEEE 802.11g (up to 54
Mbps data transfer rate in 2,4 GHz, backward-compatible to IEEE
802.11b) for operation with mobile devices
•
AirLancer MC-54g
PC card (Cardbus) according to IEEE 802.11g (up to 54 Mbps data tranfer
rate in 2,4 GHz, backward-compatible to IEEE 802.11b) for operation with
mobile devices
•
AirLancer PCI-54ag
Dual band PCI adapter according to IEEE 802.11a (up to 54 Mbps data
tranfer rate into 5 GHz frequency band) or IEEE 802.11g (up to 54 Mbps
data tranfer rate into 2,4 GHz frequency band, backward-compatible to
IEEE 802.11b) for installation in a stationary desktop PC. You find an
external dual band antenna enclosed with the product.
1.5.1 Encryption in three security steps
Several countries regulate the operation of encryption technologies. Air-
Lancer 54 Mbps Wireless LAN adapters support three different variants of
encryption:
•
WEP64 – for encryption in accordance with W ired E quivalent P rivacy
(WEP), encryption keys are used with an effective length of 40 bit.
•
WEP128 – encryption keys with a length of 104 bit.
•
WEP152 – operate with keys with a length of 128 bit (only applicable
with
AirLancer 54 Mbps cards).
Please inform yourself about the valid legal regulations for employment of
encryption technology in the country you want to use a AirLancer Wireless
LAN adapter. Pay attention to use no devices which support inadmissible
encryption technologies.
