mCore™ .NET SMS Library
1.2
GSM Modems
mCore™ .NET SMS Library 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™ .NET SMS Library 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 appropriate modem driver
driver for Infrared or Cable, which creates a virtual serial
port.
