With this background, Sky microwave Corp. develops its MOD 9001 BENQ GSM/GPRS
Modem. Users of this product can add wireless communication capability easily to their own
products, and then, develop many applications.
The MOD 9001 BENQ GSM/GPRS Modem mostly fits the need of data transfer, with
SMS data communication, GPRS data navigation, Circuit Switch / Data Connectivity, TCP/IP
protocol etc. Because the easy setting up in SCM (Single Chip Micyoco), it is convenient for
network data communication. The MOD 9001 BENQ GSM/GPRS Modem with small size,
which fits both embedded application and external peripheral equipment. The AT command
set and RS232 interface will offer easy data connection without any extra circuit control.
Traditionally, the above applications use digital cellular, CDPD or other wire-line modem to
do communication, and these technologies are of the disadvantages of high communication
expense, limited communication range, dial before communications, etc. When we begin to
use MOD 9001 BENQ GSM/GPRS Modem, all these problems disappeared.
