Wherever no other transmission medium such as a dedicated line or telephone network is
available and where the setting up of a separate wireless network would involve high cost,
data transmission using a GSM network is a practical alternative.
This is, of course, possible only when there is an adequately strong GSM signal at the
relevant location. The latest SINAUT quadband mobile wireless modem makes operation in
the GSM networks available worldwide(850, 900, 1800 and 1900 MHz range).
SINAUT ST7 provides two options for data transmission over GSM mobile wireless:
1. With the GSM modem MD720-3
2. With the GPRS modem MD740-1

Data transmission on demand by establishing a dial-up connection over a mobile wireless
network (CSD: Circuit Switched Data). The sending of SMS messages to standby
personnel is also possible here.
The duration of the dial-up connections or the number of SMS messages sent is charged.
Permanent online connection between station and control center using the GPRS service
(General Packet Radio Service) of a GSM provider. Data can be transmitted immediately
at any time.
Despite being permanently online, only the amount of transmitted data is charged.
