This paper presents a flexible telemetering system based on a mobile medical communication platform for long-term medical data acquisition. The system is able to gather data from multiple medical relevant sensors like electrocardiography. Preprocessing is performed before wireless transmitting the data either via Bluetooth to a local station like a laptop or mobile phone or via GSM / UMTS to a central infrastructure (server). An implemented emergency call function provides an automatic phone call to an assistance hot-line and offers the possibility of transferring online personal vital parameters as well as the patients GPS coordinates via UMTS.
