ZyWALL USG 20/20W User’s Guide

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 card you use, the 

signal strength to the service provider’s base station, and so on.

•  (refer to 

• 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.
