1 Introduction
The advantages of wireless LANs are obvious: Notebooks and PCs can be set
up where they are wanted—problems with missing ports or construction al-
terations are a thing of the past with wireless networking.
Network links in conferences or presentations, access to resources in adja-
cent buildings and exchanging data with mobile units are only a few of the
options available with a wireless LAN.
The access point plays the central role in enabling these options in an exist-
ing wired network. All stations in the wireless network access the LAN via
the access point.
Your entire LAN is connected to the outside world via the integrated IP router
and the ISDN interface. Access to the Internet for the entire LAN or office
functions such as fax and answering machine at all workstations are only
some of the advantages offered by the ISDN router.
Notes on using wireless LAN devices
ELSA Wireles s LAN products can use up to 13 radio frequency channels in a
frequency band between 2400 MHz and 2483 MHz. The devices are approved
for operation in all EU countries and Switzerland. Use of the devices is reg-
ulated throughout Europe by the 1999/5/EG guideline of the European Parlia-
ment and Council Directive of 9 March 1999 regarding Radio and
Telecommunication Terminal Equipment (R&TTE) and the mutual approval of
their conformity. Please observe the approved frequencies for individual
countries as listed in the appendix.
ELSA is not responsible for disturbances or interference caused by unautho-
rized modifications made to the devices. ELSA will not be held liable espe-
cially for the consequences of connecting external antennas or cables that
are not explicitly designed for use with
ELSA LANCOM Wireless and Air-
Lancer devices.
See the appendix for more information on CE conformity.
