GR47/GR48 is a wireless module carrying complete set of
GSM/GPRS of radio and data processing functions. Its all
functions are integrated in an ultra small chip (only 50
x 33 x 7.2 mm); The simplest development --- the TCP/IP
Protocol stack enables the users to to shorten the period
of research and development to the greatest extend. GR47/GR48
is matchable, making external control of the connection
ports more effective, hence to make the GR47/GR48 product
more suitable for the M2M solutions. Inserting Controller
can also be applied to Emergency System, Data Collection,
and other applications (when GR47/GR48 and the M2M functional
package connected).
Characteristics£º
The GR47 is completely compatible to all hardware connection
ports of GM47, it can provide the GM47 user a seamless upgrading.
An Inserting Controller is compatible to the group;
Data, Fax, SMS and Tone
Double-wave band EGSM 900/1800MHZ(GR47) or GSM 850/1900
MHz(GR48)
Expand IO£º
4+1 channels and the P channel
GPS Integral Operation£º
Passed GSM Phase 2+ standards
GR48 FCC/PTCRB passed the tests of Remote Testing and Romote
Control, applicable to (HR/FR/EFR)
Wide applicaitons: Wireless metering and control, GPS Car
Tracking Terminal, wireless public phones, wireless POS
device, Wireless PDS, wireless data transmission, and etc..
The inserted TCP/IP Protocol stack allows you access to
the Internet more easier and convenient, greatly reduces
your development time.
