Caution: If you want to connect remotely to your PinPoint-E using
TCP/IP, the IP address given to your modem by Verizon cannot be a
private or internal IP address (such asspecial private network) unless
you are on the same network or inside that network’s firewall (such as
with frame relay).

EV-DO Communication
CDMA (Code Division Multiple Access) is the underlying
digital radio network technology used by many cellular
providers across the globe and is prevalent in North America.
To provide backward compatibility and seamless connections
in a wider range of locations, your PinPoint‐E will fall back to
1x when EV‐DO is not available.

EV-DO
EV‐DO (Evolution Data Optimized) provides a broadband‐like
cellular data connections that is 10 times faster than 1x/CDMA
service. With the high‐speed connection, users can experience
faster downloading when accessing the Internet and retrieving
e‐mails, including large attachments and other bandwidth‐
intensive applications. EV‐DO is often referred to as Mobile
Broadband and Cellular Broadband.

EV‐DO revision A is an enhancement on the original revision 0
adding expanded upload capabilities and a more robust
connection overall. In addition to increasing the downlink
speed, revision A also increases the uplink speed. In addition,
it is backwards compatible and automatically connects with
existing and broadly deployed EV‐DO Rev. 0 and 1x networks
ensuring reliable and pervasive connectivity.
