Product Description

The Multi-Tech MultiModem® iCell is a mid-range wireless modem. It is available in three models that require a SIM.

All models contain an embedded TCP/IP protocol stack for internet connectivity, serial and USB connectors for

modem configuration, USB connection for future use, and a General Purpose Input/Output (GPIO) connector for

customer interface connection. All MultiModem iCells can be desktop or panel mounted.

The MultiModem iCell modems are available in four models:

Model Description

MTCMR-H (HSDPA)

Standards based tri-band UMTS/HSDPA performance

MTCMR-E (EDGE)

Quad-band E-GPRS Class 10 performance

MTCMR-G-F4 (GPRS)

Quad-band GSM/GPRS Class 10 performance

All models contain an embedded TCP/IP protocol stack to bring internet connectivity to any device without making

changes to its hardware design. Using the Internet protocols and the wireless connection to an IP network, the

modems send and receive data over the Internet. The modems offer short message service (SMS) features such as

text and PDU, Point-to-point (MT/MO) and cell broadcast.

The MultiModem iCell modems deliver some of the fastest cellular wireless data speeds using the various internet

protocols. This is ideal for highly data-intensive applications such as remote video surveillance and other multimedia

applications where you are sending digital images, web pages and photographs.

The MultiModem iCell modems are designed around a wide variety of interface options including serial RS-232, USB,

and General Purpose Input/Output (GPIO). The serial RS-232 and USB connections provide seamless connectivity

for configuration of your application. The GPIO interface provides five user configurable GPIO’s as CMOS input or

output ports to be connected to a customer’s peripheral device. A customer application in which the GPIO interface

could be used is one with a monitoring device connected to the GPIO interface in which the monitoring device

triggers an event in the IP stack to establish a TCP or UPD socket connection or send an email stating that the

monitoring device was triggered by high water.

Universal IP

All MultiModem iCell modems are equipped with an embedded TCP/IP protocol stack to automate the

connection process and open a socket for bidirectional data transmission. Multi-Tech’s Universal IP supports

Telnet, SMTP/POP, FTP, TCP, UDP, PPP as well as other automatic call management options.

AT Commands: The embedded TCP/IP stack on the MultiModem iCell modems is configured

using the Universal IP (UIP) AT Commands. These commands are documented in the Reference

Guide document number S000457x.
