The results of a feasibility study using the 4G network in healthy volunteers have been reported and feasibility data using the 3G network in healthy volunteers are available (unpublished data). The investigators recently evaluated the safety, technical feasibility and reliability of in-ambulance telemedicine in patients during emergency missions by a Paramedic Intervention Team of the Universitair Ziekenhuis Brussel (Feasibility study on AmbulanCe-based Telemedicine, FACT) and yielded satisfactory results (paper under review, trial registered at clinicaltrials.gov: NCT02119598).
