The advantages of the UMTS/HSPDA solution
The combination of UMTS/HSPDA, WLAN, DSL and VPN opens up a comple-
tely new range of possibilities in enterprise connectivity—for example, mobile
conference rooms that are connected via UMTS/HSPDA and offer Internet
access over WLAN or access to the company network via VPN. As a back-up
connection for site coupling, UMTS/HSPDA is cheaper and/or faster than the
conventional alternatives, ISDN and Analog. Furthermore, it is significantly
less prone to failure as there are no cables which are at risk from construction
works. Apart from that, UMTS/HSPDA is able to bridge the “last mile” for cus-
tomers who do not have access to an equivalent broad-band connection.
The UMTS/HSPDA card is simply operated in the CardBus expansion slot of the
appropriate LANCOM devices. The device automatically switches Internet
access between UMTS/HSPDA and GPRS depending on availability.

“Last mile“ via UMTS/HSPDA
The Internet connection over UMTS/HSPDA is recommendable wherever a
broadband Internet connection is not available. When accessing the Internet
with UMTS/HSPDA you can currently reach significant higher downstream
rates than with an ISDN connection.
