Benefits/Features in Applications
Short Development Time. The MultiModem® GPRS can make your existing and next generation
device, machine, or system, communication-ready without requiring any hardware changes to its
design. It actually provides faster time-to-market because it relieves the burden and expense of
obtaining network and RF approvals. This complete, ready-to-deploy wireless modem allows you to
enhance your product while you focus on developing its core features.
Voice Features. The MultiModem® GPRS provides telephony and Dual Tone Multi Frequency
(DTMF) functionality. It also allows for emergency calls as well as echo cancellation and noise
reduction (option), and full rate, enhanced Full Rate and Half Rate (FR/EFR/HR).

Industrial Chassis. The MultiModem® GPRS is packaged in a rugged, water resistant, industrial
chassis. The chassis has a USB connector for power and data. It has an SMA antenna connector.
It also has modular phone handset receptacle. The chassis can be side-mounted on a panel or top-
mounted on a desktop or other surface. A set of LEDs indicates the modem’s operational status.
Packet-Switched Data. The MultiModem® GPRS supports GPRS Class 10 packet-switched
cellular data. This enables mobile Internet functionality by allowing interworking between the
existing Internet and the cellular network at speeds up to 85K bps. Any service that is used over
the fixed Internet today – File Transfer Protocol (FTP), web browsing, chat, e-mail, telnet -- is
available over the cellular network, as well. The MultiModem GPRS supports PBCCH and coding
schemes CS1 to CS4, and is compliant with SMG31bis.
Circuit-Switched Data (CSD). The MultiModem® GPRS also supports GSM circuit-switched
cellular data connections. Circuit-switched data connections support speeds up to 14.4K bps,
Class 1 and Class 2 Group 3 fax, as well as MNP2 V.42bis compression. CSD cellular wireless
connections are ideal for applications that require a quick wireless replacement of an existing point-
to-point analog dial-up connection. They integrate seamlessly with your current application
requiring little infrastructure change.
Internet-Enabled. The MultiModem® GPRS includes an embedded TCP/IP protocol stack to bring
Internet connectivity to any device. Using the embedded Internet protocols and the wirless
connection to an IP network, it sends and receives data over the Internet. It can also serve a single
web page in response to a web browser request.
