Connecting to Verizon
The AirLink GX440 uses Verizon Wireless as an ISP (Internet Service Provider)
to connect you to the Internet.
Steps of a Connection:
1. When your AirLink GX440 is powered on, it automatically searches for
cellular service using LTE/CDMA-based cellular technology.
2. Your AirLink GX440 establishes a communications link to the Verizon network
with the radio module.
3. When your AirLink GX440 has received its IP address from Verizon, a
connection to the Internet or the cellular network is also available for
computers or other devices connected directly to the AirLink GX440.
The AirLink GX440 will perform routing for all internet traffic to and from the
computers or other end devices.
With the AirLink GX440 in Ethernet Public mode, only one device connected to
the Ethernet port will receive the public IP address which is the one provided by
the cellular network. In Ethernet Private mode, with a hub or switch connected to
the Ethernet port, the AirLink GX440 will provide NAT (network address
translation) for a range of computers or other devices connected to the switch or
hub and allows Internet access to all of them.
Dynamic vs. Static IP Addresses
There are two types of addresses on networks: dynamic and static.
• Dynamic addresses are assigned on a “need to have” basis. Your AirLink
GX440 might not always receive the same address each time it connects with
Verizon.
• Static addresses are permanently assigned to a particular account and will
always be used whenever your AirLink GX440 connects to the Internet. The
IP address will not be given to anyone else.
Most ISPs (cellular included) use dynamic IP addresses rather than static IP
addresses since it allows them to reuse a smaller number of IP addresses for a
large number of customers. A dynamic IP address is suitable for many common
Internet uses, such as web browsing, looking up data on another computer
system, or other client functions (such as data only being sent out or only being
received after an initial request).
Tip: If your account with Verizon includes a dynamic IP address and you need a static IP,
please consult your Verizon Representative for more information about changing your
account for static IP support.
