is integrated into the printed circuit board. The two slide-out SIM card readers is accessible

from the front panel. The SMA antenna connector is accessible from the front panel.

GSM/GPRS/EDGE module

• Communicates in four GSM bands (850MHz, 900MHz, 1800MHz, and 1900MHz).

• In the GPRS mode it is able to transmit in three „Time Slot“ and receive in two (GPRS

multi-slot class 10 – the maximum bit rate of reception is 42.8 kb/s) or transmit in one

„Time Slot“ and receive in four (GPRS multi-slot class 12 – the maximum bit rate

of reception is 85.6 kb/s).

• In the EDGE mode it is able to transmit in three „Time Slot“ and receive in two (EDGE

multi-slot class 10 – the maximum bit rate of reception is 118.4 kb/s) or transmit in one

„Time Slot“ and receive in four (GPRS multi-slot class 12 – the maximum bit rate

of reception is 236.8 kb/s).

• Supports coding schemes CS1 to CS4 and MCS1 to MCS9.

Beware! The transmitting and receiving in timeslots depends on the operator networks

possibilities.

2.7.2. Control microcomputer

The core of the router is a 32-bit ARM microprocessor with 512MB DDR2 SDRAM,

128MB FLASH, 1MB MRAM, serial interface RS-232 and an Ethernet interface 10/100 Mbit/s.

The microcomputer is connected to the EDGE EES3 module through the USB interface

and controls the communication via EDGE/GPRS. Towards to the user it is connected

on the Ethernet interface.

The software is built on the Linux operating system.

The router support services as like DHCP, NAT, Open VPN, IPsec tunnels, etc.

The modem settings are saved in the FLASH memory. All modem configurations can

be done through a web interface (HTTP), which is protected by security password.

Actual firmware version: 2.1.1 (4.5.2011)
