The GSM network is the basis for worldwide transmission of voice, data and text
messages to mobile end devices. For industrial use, data is transmitted using the
- CSD - Data transmission via a voice channel (just like a normal modem)
- SMS - Sending and receiving short text messages
- GPRS/EDGE - Packet-switching data service, usually via an internet connection
GPRS and EDGE can provide higher data rates due to channel bundling and the
advantage of payment according to data volume. This allows you to set up a virtual
dedicated line at a very low cost, for sending many small data packets (e.g.
Local ports for GPRS devices
|serial:||Behaves like a standard modem when connected to a serial port (RS-232), all protocol stacks|
|Ethernet:||Router with NAT and Port Forwarding, Ethernet Access 10BT|
|PPP:||IP data is passed to the program via the serial port (RS-232) and via PPP. The program can|
process PPP connections and IP connections directly.
All INSYS GSM/GPRS/EDGE devices, except INSYS GPRS/EDGE 5.0 Ethernet, connect to the
local program (e.g. a control program) via a serial port (RS-232). They can be configured
using the free software HSComm (Download information on the right).
INSYS GPRS/EDGE 5.0 Ethernet have an ethernet connection and can be configured using
a web interface. For other GPRS routers with integrated switches, please see the link
All devices can log themselves back in automatically after power outages. For stationary
operations, automated regular logout and login is supported. Within the GSM network,
4 frequencies are in use worldwide - the INSYS devices either support all four (quad band)
or only the two used in Europe (dual band).
