Mobility Internet Access
You may have the experienced a need of Internet access in a location where wired connection is difficult
to deploy, e.g. in countryside or mountain. Or you are just in a public environment without Internet access,
like in a park, on a bus, in a train or metropolitan subway, etc… Or you may temporarily need Internet
access when you are in your exhibition booth and need Internet access for some demonstration. ZyWALL
2WG is especially designed for the mobility Internet access; it is light to carry everywhere and can utilize
a 3G card for dial up to get the Internet access. Besides, you could utilize the embedded wireless card to
provide wireless access for your LAN users.
Not only the mobility, you could also use ZyWALL 2WG as your WAN backup in the small office or
SOHO. You could further choose a certain load balancing mechanism to perform dual WAN access.
In summery, you could utilize the 3G wireless access for your primary WAN, or backup WAN, or work
with your primary WAN(Ethernet or PPP) together as a dual WAN application.
