Analysis and Measurement of a Wireless Telemedicine System

The analysis and measurement of a multicollaborative wireless telemedicine system operating over third generation (3G) mobile networks is presented. It is designed to communicate the personnel of an ambulance with medical specialists in a remote hospital through a Universal Mobile Telecommunication System (UMTS) mobile access. The system architecture is based on advanced signalling protocols that allow multimedia multi-collaborative conferences in IPv4/IPv6 3G scenarios. The system offers real-time transmission of medical data and videoconference, together with other non real-time services. It has been optimized specifically to operate over 3G mobile networks using the most appropriate codecs. Measurements show a reliable performance over IPv4 UMTS accesses (64 Kbps in the uplink) and also allow to dimension certain system parameters in order to improve the quality of the services offered
