Network
Selection
This field appears if you selected a 3G device that allows you to select the type of
network to use. Select the type of 3G service for your 3G connection. If you are unsure
what to select, check with your 3G service provider to find the 3G service available to
you in your region.
Select auto to have the card connect to an available network. Choose this option if you
do not know what networks are available.
You may want to manually specify the type of network to use if you are charged
differently for different types of network or you only have one type of network
available to you.
Select GPRS / EDGE (GSM) only to have this interface only use a 2.5G or 2.75G
network (respectively). If you only have a GSM network available to you, you may
want to select this so the ZyWALL does not spend time looking for a WCDMA network.
Select UMTS / HSDPA (WCDMA) only to have this interface only use a 3G or 3.5G
network (respectively). You may want to do this if you want to make sure the interface
does not use the GSM network.
