DGS-200
GSM (Global System for Mobile Communications) is the world's
most widely used cell phone technology, it is a standard developed
by the European Telecommunications Standards Institute (ETSI). GSM
is a second generation (2G) standard for mobile networks.
GPRS technology is an extended version of GSM and this technology
improves the data transmission rate and network capacity.

GSM/GPS Experimental Set
DGS-200 covers two topics in modern
communication: GPS technology and
GSM / GPRS technology. In GPS module,
the GPS receiver decodes the NMEA
data strings from the satellites and
outputs them to software interface for
the discussion of current position, speed,
direction, time, etc.
In GSM / GPRS module, the usage of AT commands is introduced. Students
can use software interface to send AT command to control GSM / GPRS module,
send SMS message and make a phone call through headset interface, or access
to the Internet.

The interface supports a clear and user-fr iendly experimental
environment. Al l experiments can be implemented step-by-step.
Moreover, students can follow the relevant description of each step
listed in our manual to complete the experiment easily.
