LANCOM 3550 Wireless

 Chapter 5: Setting up the UMTS profile

5.3.3 UMTS/HSPDA only or automatic UMTS/HSPDA/GPRS selection

UMTS/HSPDA coverage is not yet universally available. It is still possible to

establish a data connection even in areas without UMTS/HSPDA reception by

selecting the 'automatic' operating mode. With this setting, the data card in

the LANCOM will initially attempt to establish a connection via UMTS/HSPDA.

The card will automatically switch to the GPRS network if the UMTS/HSPDA

signal proves to be too weak to support data transfer of the necessary quality.

If required, the operating mode can be permanently set to either UMTS or

GPRS. The desired operating mode can be set in the UMTS/GPRS profile set-

tings which are to be found in LANconfig in the configuration area 'Interface'

on the 'WAN' tab with the UMTS/GPRS profile button.
