MobiHealth and HealthService24 are two major EU projects targeting the development and validation, with extensive medical trials, of innovative systems and services for mobile health care. Biosignals are measured by sensor devices connected to a wireless Body Area Network. These signals are transmitted reliably and securely over public wireless networks (e.g. GPRS, UMTS) to a remote healthcare organisation where healthcare professionals can monitor, diagnose and provide advice to patients in real time. The developed system and its services is in the last phase of the pre-commercial validation, expecting a commercial release of the system late 2006.
