  1. Wireless Applications in Mobile Telemedicine Kent Tonkin, Assistant Director for IT, CERMUSA

  2. The Center of Excellence for Remote and Medically Under-Served Areas CERMUSA Defined • Research Center • Saint Francis University, Loretto, PA • Identify Sustainable Technology Solutions for improved ACCESS to quality healthcare and education in rural, isolated and/or under-served areas.

  3. The Center of Excellence for Remote and Medically Under-Served Areas Medical Communications Needs • Continuous audio communication • Vital signs (EKG, SPO2) • “Offline” data storage

  4. The Center of Excellence for Remote and Medically Under-Served Areas Technology Overview Technology Goals • Vital signs • Images/motion video • Multiple pipelines • Use of public infrastructure vs. establishing infrastructure

  5. The Center of Excellence for Remote and Medically Under-Served Areas Technology Overview TechnologyDifficulties • Sporadic mobile coverage • Questionable bandwidth • Combined pipelines • Relevant equipment availability

  6. The Center of Excellence for Remote and Medically Under-Served Areas Technology Overview • Currently using AMPS, Spread Spectrum (2.4 GHz) and UHF (licensing in process) • Attempted transmission: Audio, patient data/vitals, video

  7. Intelligent Router Other Cellular VHF UHF Spread Spectrum Hospital Receive Site The Plan

  8. The Center of Excellence for Remote and Medically Under-Served Areas Difficulties so far…. • Bandwidth, bandwidth, bandwidth • IP routing over low bandwidth • Handling other forms of data

  9. The Center of Excellence for Remote and Medically Under-Served Areas Video from an Ambulance? • H.323 VTC • 2.4 GHz Spread Spectrum • Dual mobile and fixed antennae • Variable coverage/line of sight

  10. Public Network Gateway Mobile H.323 Gateway Stand-alone IP VTC Wireless TCP/IP Network Connection

  11. The Center of Excellence for Remote and Medically Under-Served Areas Will it work? • Best possible outcomes will continue to improve • More bandwidth=more possibilities • All communications converge on single standard

  12. The Center of Excellence for Remote and Medically Under-Served Areas Next Steps • New “diversity” switch • Satellite data • Experimentation on “real world” bandwidth (4800-19.2kbps) • Digital radios

  13. The Center of Excellence for Remote and Medically Under-Served Areas New Technology Challenges • Cost/Investment • How “standard” are standards? • Quality • Path of progression (3G) • Security • Technology conflicts
