  6. 6. M-health in 2012
  7. 7. m-health is one of the fastest growing vertical market within the Mobile service domain Some Interesting ‘ Google’ Statistics: Google Search - March 2011 ‘m-health’ > 102,000,000 Hits In the US, Verizon launched in November 2009 a health focused business unit, ‘Verizon Connected Health’. In the UK, Vodafone and in France Orange outlined plans in December 2009 for the mobile health business. Opportunities in the global mobile healthcare market are estimated to be worth between $50bn and $60bn in 2010 Source: McKinsey & Company-2010 500M people will be using healthcare mobile applications in 2015 Source: research2guidance.comstepanian 2012

  9. 9. Definition of ‘4G Health’ REF: Istepanian, IEEE Trans. Info. Tech. Biomedicine- 2012©Robert S.H. Istepanian 2012
  10. 10. Concept of 4G health REF: Istepanian, IEEE Trans. TITB- 2012 LTE World Summit 2012©Robert S.H. Istepanian 2012 Barcelona 23-24 may 2012
  11. 11. Key 4G Health Categories : Some Potential applications of ‘long term evolution of m-health’ services : •4G Wellness, prevention and long term chronic diseases management systems. •4G medical Multimedia services and diagnostics systems. •4G mobile emergency care and response systems. •4G smart personalised healthcare.©Robert S.H.

  13. 13. Diabetes as Global Epidemic Diabetes Atlas-2011 from www.idf.org
  14. 14. Common m-health business applications Mobile Diabetes Management Systems Ref: Istepanian etal, JTT, 15,3 2009
  15. 15. Mobile Diabetes Systems as a healthcare business PositiveID announced that the FDA had cleared itsCellnovo from CE mobile health diabetes management system, iGlucose. Mhealth News, Nov. 2011 Interest in mobile health (mHealth) applications for self-management of diabetes is growing. In July 2009, we found 60 diabetes applications on iTunes for iPhone; by February 2011 the number had increased by more than 400% to 260. Ref: J. Med. Internet. Res. 14, 2012
  16. 16. Benefits of m-health for Diabetes management•Self-management (empowerment) is key tominimising the long-term complications of diabetes.•Lifestyle and behaviour.•Personal responsibility for his/her care.• Giving the patient the necessary medicalinformation he/she requires• Provision of patient engagement with his/her carer• ‘Implicit enforcement’ of compliance by providing thenurse/doctor with the information needed to knowif the patient is taking SMBG or not.

  20. 20. QoS issues in LTE In general QoS is an important area for the successful growth of LTE networks. m-health applications have various requirements from the transport network in terms of delay, bandwidth and error rate that they desire for optimal performance or user experience. This poses a challenge for deployment of LTE networks. In general there are two types of bearers that have been defined in the LTE Rel-8 : (i) Guaranteed Bit Rate and (ii) Non-Guaranteed Bit Rate: In (i) where network resources equivalent to a certain bit rate are reserved at the time of the creation of the bearer. In (ii) is typically used for interactive applications such as IMS signaling, progressive video streaming, web browsing, chat, etc©Robert S.H. Istepanian 2012
  21. 21. Medical QoS (m-QOS) REF: Istepanian etal. - IEEE J Selected Areas in Communications, May 2009Istepanian 2011
  22. 22. To manage m-QoS Cross Layer Optimization is required Abstraction Sk =(V k , L k S´k =(V´ k , L´ k ) Application ) CLO Input: Layer Abstraction (Video streaming Quality) 1-Frame Size 2-Frame Rate Presentation 3-PSNR Session External m-QoS Cross-layer CLO Output: Cross layer strategy policy and network Optimizer limitations TCP/UDP/RTP IP 1-Modulation and coding 2-SNR MAC 3-BER Abstraction CLO Input: Layer Abstraction (Link Status) 4-Utilization Phy 5-Operation Frequency LTE World Summit 2012©Robert S.H. Istepanian 2012 Barcelona 23-24 may 2012
  23. 23. PSNR Vs ThroughputA sample of the average throughput of the ultrasound data stream captured by the expert using theWiMAX and HSUPA platform is shown. Experimental results show that both WiMAX and HSUPAsupport uplink medical video streaming with average 0.6 Mbps.
  24. 24. RTT results of different ultrasoundvideo stream packet sizes over WiMAX and HSUPA Fig. 1 and 2 show the comparative results of the RTT values for different packet sizes over HSUPA and different WiMAX modulation and coding schemes. The results show that the WiMAX provides better RTT performance compared to HSUPA network.
