Umts/Hspda Backup - Lancom 3550 Wireless User Manual

LANCOM 3550 Wireless
Chapter 1: Introduction
Mobile WLAN, e.g. for a „mobile
conference room".
For a group of staff members, who e.g. often work together on projects at a
customer's location, a so-called mobile conference room can be established.
The access point then only has to be configured once by the administrator; the
staff members on location simply have to supply the device with power and
slot in the data card. With an appropriate configuration the router automati-
cally builds up a connection to the Internet. The result is that all notebooks
with a compatible passphrase in the WLAN configuration can directly access
the Internet. As long as the router has a VPN connection to headquarters, the
field staff can also access all of the services in the network of headquarters
(fileserver, mailserver, data bases) from the mobile office.

UMTS/HSPDA Backup

The high availability of data lines e. g. between branch offices and headquar-
ters in large company networks are in the majority of cases established over
backup solutions with ISDN or analog. The standard Internet connection is
then provided e. g. over a DSL connection, and an ISDN or analog line is used
as a backup line in the case the DSL line breaks down.
