With the MC35 GSM/GPRS module, Siemens Information and Communication Mobile (IC Mobile) is offering a new product for wireless, rapid, reliable and cost-effective data transfer. This product offers manufacturers of consumer goods in the mobile computing sector in particular an ideal communication platform. From January 2002, Siemens IC Mobile will be offering the MC35
Terminal with a simple plug-and-play solution for system integration. With its worldwide tailor-made integration support services, Siemens IC Mobile can help its customers develop their applications and offer them considerable benefits in terms of costs and time-to-market.
The MC35 Module
The competitiveness of mobile computers will depend more and more on their ability to communicate. The new MC35 GSM/GPRS module from Siemens greatly increases the speed of wireless data transfer. The module is particularly
suitable for integration in notebooks, handhelds/PDAs and portable navigation terminals. With GPRS, mobile workers can, for example, quickly and inexpensively coordinate order data with their headquarters, arrange meetings, send and receive e-mails and carry out remote maintenance tasks.
Measuring just 54.5x36x6.75 mm and weighing only 18 grams, the MC35 is the ideal basis for implementing smart phones and mini cell phones with integrated GPS satellite navigation modules for personal positioning information.
The module is also perfect for industrial applications such as integration in alarm systems, switching cabinets and electricity meters and for direct installation in vehicles, on-board computers and car radios.
Apart from GPRS with data rates of up to 85.6 kilobit/s (GPRS Multislot Class 8 downlink from the base station), the MC35 supports conventional fax and data communication at up to 14.4 kilobit/s, SMS messaging and reception of cell broadcast services. Obviously, the dual-band module (for GSM 900 and GSM 1800 systems) can also be used for voice communication. The MC35 is
controlled entirely via the serial interface by means of AT commands. These standardized commands enable software developers to produce their individual communication solutions very quickly and to access the full GSM/GPRS functionality of the module. With its cellular engine, Siemens IC Mobile is therefore providing its customers with in-depth GSM and GPRS know-how so that developers can concentrate fully on implementing their particular solutions.
In developing the MC35, we paid great attention to making migration from GSM to GPRS as simple as possible. The new module is fully compatible with the TC35 dual-band module, which will continue to be available. Migration to GPRS can therefore be a simple matter of replacing one module with another.
The MC35 Terminal
From January, Siemens will be offering the MC35 in the form of a plug-and-play terminal for simple integration in systems. At just 65x74x33
mm the "MC35 Terminal" is smaller than a packet of cigarettes. It weighs only 130 grams and contains a SIM card reader, an audio interface for a handset, an antenna connection and a serial interface with a 9-pin socket. The terminal is designed to operate on input voltages of between 8 and 30 V and within a temperature range of -20 degrees C to +55 degrees C. These wide ranges make the unit extremely versatile for integration in a wide variety of systems including fleet management, traffic control and security systems, measuring stations for monitoring pollutants, parking ticket machines and vending machines.
The MC35 GSM/GPRS module and MC35 Terminal modules are marketed through direct sales for wireless modules by Siemens IC Mobile and distributors. Siemens offers application vendors comprehensive system and interface documentation. Its "Wireless Modules Support Team" is on hand throughout the world to help with problems ranging from implementation and instrumentation to official approval.
