IP Address Assignment
Global System for Mobile communication (GSM) (Only supported in Digi
Connect WAN and Digi Connect RG)
The GSM protocol is a digital mobile telephone system used in Europe and other parts of
the world. There are three major types of digital mobile systems and GSM is the most
widely used. GSM compresses and digitizes data and sends it down a channel along with
two other streams of user data - each in its own time slot.
General Packet Radio Service (GPRS) (Only supported in Digi Connect WAN
and Digi Connect RG)
GPRS is based on Global System for Mobile (GSM) communication. GPRS is a packet-
based wireless communication service that transports data rates from 56 up to 114 Kbps
and continuous connection to the Internet for mobile phone and computer users. Higher
data rates allow users more flexibility in the media they transmit. In theory, GPRS packet-
based service costs users less than circuit-switched services since communication
channels are being used on a shared-use, as-packets-are-needed basis rather than
dedicated only to one user at a time. It should also be easier to make applications available
to mobile users because the faster data rate means that middleware currently needed to
adapt applications to the slower speed of wireless systems will no longer be needed.
Enhanced Data Rates for Global Evolution (EDGE) (Only supported in Digi
Connect WAN and Digi Connect RG)
EDGE is a faster version of the GSM wireless service and designed to deliver data at rates
up to 384 Kbps and enable the delivery of multimedia and other broadband applications to
mobile phone and computer users. The EDGE standard is built on the existing GSM
standard, using the same time-division multiple access frame structure and existing cell
arrangements.
There are several ways to assign an IP address to a Digi Connect device:
Static IP: Assign a specific IP address to a device, through the Digi Device
Setup Wizard, the default web interface, or the Command-Line Interface.
Using Dynamic Host Configuration Protocol (DHCP). The device server’s
default configuration is as a DHCP client. Dynamic Host Configuration
