The actual data rate you obtain varies depending on the 3G card you use, the
signal strength of the service provider’s base station, your service plan, etc.
If the signal strength of a 3G network is too low, the 3G card may switch to an available 2.5G
or 2.75G network. See the following table for a comparison between 2G, 2.5G, 2.75G, 3G and
3.5G wireless technologies.
After you insert a 3G card in the ZyWALL, the 3G connection becomes WAN 2. Refer to the
for the type of 3G cards that you can use in the ZyWALL along with
the corresponding supported features.
