1.2 The advantages of the UMTS/HSPDA solution
The combination of UMTS/HSPDA, WLAN, DSL and VPN opens up a com-
pletely new range of possibilities in enterprise connectivity—for example,
mobile conference rooms that are connected via UMTS/HSPDA and offer Inter-
net 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 signifi-
cantly less prone to failure as there are no cables which are at risk from con-
struction works. Apart from that, UMTS/HSPDA is able to bridge the “last
mile” for customers 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.
1.2.1 “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.
