The WORLD version is meant for use in Europe and other countries,
especially the USA. Apart from the European CE standard, it also meets
the American FCC standard. The maximum number of channels is 11.
Accessing an EU access point with an AirLancer WORLD version
In order to be able to access an EU access point (supports 13 radio channels)
with an
AirLancer WORLD version (only supports11 radio channels), you must
choose a channel between 1 and 11 on the access point.
For guidance regarding the manual setting of channels please refer to the
documentation of your access point. A list of the radio channels that are sup-
ported by the two versions is available in paragraph 9.2 'Radio channels' on
page 54.
1.5.2 Encryption in two levels of security
Some countries regulate the use of encryption technology. This is why there
are two versions of every
AirLancer wireless LAN adapter:
WEP64—for the encryption according to W ired E quivalent P rivacy (WEP)
keys are used with an effective length of 40 bits.
WEP128—this model version uses keys with a length of 104 bits. The
encryption attained is considerably stronger, compared to the models
using WEP64.
Please inform yourself on the current legal regulations for the use of
encryption technology in the country where you want to use an A
AirLancer. Make sure not to use devic e s that support illegal encryption's
techniques.
Detailed information on the use of WEP encryption can be found in chapter 8
'Security in the wireless LAN' on page 49.
