Introduction to the Raven X
Rev 3.0 Mar.12 13
Connecting to Your Cellular Provider
The Raven X uses your cellular provider as an ISP (Internet Service Provider) to
connect you to the Internet.
Connection Steps:
1. Your Raven X establishes a PPP (Point to Point Protocol or “dial up”
connection) link to the cellular provider’s network, also called registering on
the network, and receives an IP address.
2. When your Raven X has received its IP address from your cellular provider, a
connection to the Internet or the cellular network is also available for
computers or other devices connected directly to the Raven X.
The Raven X will perform routing for all internet traffic to and from the computers
or other host devices.
With the Raven X 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 Raven X will provide NAT for a range of computers or other
devices connected to the switch or hub and 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 Raven X
might not always receive the same address each time it connects with your
cellular provider.
• Static addresses are permanently assigned to a particular account and will
always be used whenever your Raven X 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).
