GSM Modems

mCore™ is designed to work with any GSM Modem that complies with ETSI specification GSM 07.05 and supports sending of text messages in PDU mode using AT Commands. There are a large number of good GSM Modems available in the market (e.g. Wavecom, Siemens, Ericsson, Falcom, Nokia etc) which can be used with mCore™ without any problems.

GSM Phone handsets, that have a built in modem and supports AT Commands, can also be used with mCore™, however, if the SMS application has to run for longer durations or the application has to send large number of messages then we recommend using GSM Modems because:

GSM Phones normally run on battery power and no phone manufacturer recommends that the phone should be connected to battery charger continuously.
GSM Phone handsets get heated up when they are used for sending large number of messages in sequence.
GSM Modems normally run directly from power source and have a more robust design in terms of heat dissipation and heavy duty usage.
Some GSM Phone handsets like Nokia do not support AT Commands directly and require the installation of Nokia Data Suite or the appropriate modem driver driver (if using Infrared port), which creates a virtual serial port.
