RS232 EDGE Modem

RS232 Serial Wireless Cellular EDGE Modem

RS232 Serial Wireless Cellular EDGE modem presents a modern solution of mobile Internet connection. It supports EDGE technology which delivers the data transfer three times faster than GPRS. The installation is very simple, modem is ready to use after inserting the SIM card and installing drivers. Modem is suitable for the applications that require a permanent connection as in the GPRS network you don't pay for the time you are connected, but for the volume of transferred data. It presents an interesting alternative for fixed and commuted communication circuits.

Thanks to the universal communication interface (RS-232) the modem is suitable for an industrial use in many fields, e.g.:

connection of computers and private networks to the Internet as the primary or back-up route,
industrial and telemetric applications,
banking (connection of ATMs/POS terminals),
security systems with remote control,
vending machines administration,
