1.2.2 Baseband functionalities
The digital part of the WISMO Quik Q2403 Series is composed of a PHILIPS-
VLSI chip (ONE C GSM/GPRS Kernel). This chipset is using a 0,25 µm mixed
technology CMOS, which allows massive integration as well as low current
consumption.
1.3 Firmware
WISMO Quik Q2403 Series is designed to be integrated into various types of
applications such as handsets or vertical applications (telemetry, multimedia,
automotive,…).
For vertical applications, the firmware offers a set of AT commands to control
the module. With this standard software, some interfaces of the module are
not available since they are dependent on the peripheral devices connected to
the module. They are the LCD interface and the SPI bus.
