1- There is ever increasing demand on the increasing care for elderly care
and chronic patients.
2- The trend for the personalisation of the care.
3- Major reforms and new healthcare delivery models demanded by
current Economic constraints.
4- The fast pace of ICT Technology advances .

M-health in 2012
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.
m-health is one of the fastest growing vertical
market within the Mobile service domain
Opportunities in the global mobile healthcare market are
estimated to be worth between $50bn and $60bn in 2010

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.

Mhealth News, Nov. 2011 Cellnovo from CE
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
Benefits of m-health for Diabetes management
•Self-management (empowerment) is key to
minimising the long-term complications of diabetes. •Lifestyle and behaviour. •Personal responsibility for his/her care. • Giving the patient the necessary medical information he/she requires • Provision of patient engagement with his/her carer
• ‘Implicit enforcement’ of compliance by providing the nurse/doctor with the information needed to know if the patient is taking SMBG or not.

4G health: m-health Challenges from the LTE Perspective
Mission Critical v/s non-Mission Critical 4G Health Applications
1- Convergence and Interoperability challenges
2- Security and Privacy and confidentiality challenges
3- Inadequate Standards for m-health applications.
4- Development of ‘ m-health’ grade smart terminals
5- m-health based Quality of Service issues

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.
QoS issues in LTE
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

PSNR Vs Throughput
A sample of the average throughput of the ultrasound data stream captured by the expert using the
WiMAX and HSUPA platform is shown. Experimental results show that both WiMAX and HSUPA
support uplink medical video streaming with average 0.6 Mbps.
RTT results of different ultrasound
video 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.
