7.5 Cellular Configuration Screen (3G)
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is
optimized as multiple users share the same channel and bandwidth is only allocated to users when
they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet
access to mobile devices.
Note: The actual data rate you obtain varies depending on the 3G device you use, the
signal strength to the service provider’s base station, and so on.
You can configure how the ZyWALL’s 3G device connects to a network (refer to Section 7.5.1 on
page 134 ):
• You can set the 3G device to connect only to the home network, which is the network to which
you are originally subscribed.
• You can set the 3G device to connect to other networks if the signal strength of the home
network is too low or it is unavailable.
