eMobility – Strategic Applications AgendaHealth and InclusionV. Medical consultation when the specialist is on the moveDescriptionA medical doctor may be travelling and his expertise may be urgently required. In this case,patient‘s data can be immediately transferred to the specialist‘s PDA enabling an immediate firstdiagnosisUtilisationUrgent medical consultationComponentsooooECG and other medical examinations results;CT scansMRI imagesultrasound (images and video)RequirementsLow-delayHigh bit rate if MRI/CTscan/ultrasound data is involvedEntitiesHospitalsTechnical CharacteristicsDelivery requirementsHigh mobilityLow-delayReception through low-complexity devicesSymmetry of the connectionAsymmetric (hospital to medical doctor).Bit rateSeveral kbps.

Future ChallengesFuture services include:Citizen or patient to carer (C2P)/ (C2C) communications and interactionsHealth care providers tele-consultation and communicationBattlefield medical emergency telemedicine servicesDisasters medical emergency servicesRural healthcare deliveryMost of the cited services require the transmission of demanding (medical) multimedia data over wireless links.The main challenge in this area is secure delivery of medical quality (multimedia) data over wireless channels[42] [44] [41].Wireless transmission of multimedia medical data is a challenging application area due in particular to the highquality requirements of medical video, the bandwidth limitation/error prone characteristic of the wireless channelsand real-time requirements of most of the services in this area.In order to keep the required quality, lossless compression techniques are usually considered when medical videosequences are involved, resulting in huge amounts for transmission. When transmission is over band limited,error prone channels, lossless compression is not possible and a compromise should be made betweencompression fidelity and protection and resilience from channel errors and packet loss.
