Preface
Thank you for placing your trust in this LANCOM product.
The combination of UMTS/HSDPA, WLAN, DSL and VPN opens up a completely
new range of possibilities in enterprise connectivity—for example, mobile
conferen-ce rooms that are connected via UMTS/HSDPA and offer Internet
access over WLAN or access to the company network via VPN.
As a back-up connection for site coupling, UMTS/HSDPA is cheaper and faster
than the conventional alternative, ISDN. Furthermore, it is significantly less
prone tofailure as there are no cables which are at risk from construction
works. Using VRRP with the LANCOM 3550 Wireless offers fully vendor-inde-
pendent high availa-bility and a completely transparent, automatic switch of
media in the event of backup.
Apart from that, UMTS/HSDPA is able to bridge the “last mile” for customers
who do not have access to an equivalent broadband connection. The UMTS/
HSDPA card is simply operated in the CardBus expansion slot of the LANCOM
3550 Wireless. The device automatically switches Internet access between
HSDPA, UMTS andGPRS depending on availability.
