This document discusses the potential for mobile phones to become health hubs using Bluetooth Low Energy technology. It describes the Continua Health Alliance, which has selected Bluetooth as the standard for connecting medical devices. Bluetooth Low Energy allows devices like weight scales to advertise their services to mobile phones, which can then select apps to access the device's data and integrate it with health services. This creates opportunities for accessory makers, app developers, mobile carriers and others. CSR provides Bluetooth Low Energy silicon and software to enable these connections between accessories and mobile phones. Open standards, apps and certification are still needed to fully realize this vision of mobile health.

What is the Continua Health Alliance
 Non-profit alliance of >200 companies have
selected the standards that are most suitable to
the health applications they support
 Version 1 selected Bluetooth as the wireless
standard
 Version 2 will use Bluetooth Low Energy
 The alliance is supporting efforts to roll out health
technology on mobile phone platforms
Mobile connectivity for health

Bluetooth low energy is optimised to provide mobile health
 The seeds of success have been planted in the spec
 Truly low power, low power connection to the mobile phone
 Bluetooth low energy advertising is a powerful tool
 Any accessory can advertise the services that it can offer
I am a weight scale

Powerful mechanisms exist in the protocol
 Any device can listen to the adverts
There is a weight scale available

11. © Cambridge Silicon Radio 2010
Powerful mechanisms exist in the protocol
 The device can enquire about the capabilities of the
accessory
What attributes do you have?

12. © Cambridge Silicon Radio 2010
Powerful mechanisms exist in the protocol
 The accessory will report a list of its capabilities (attributes)
Here is a list

13. © Cambridge Silicon Radio 2010
Enables exploration of services
 The device can search for apps that can understand that
accessory
What apps support this accessory?

14. © Cambridge Silicon Radio 2010
Customised applications
 The device can offer the user a choice of applications
Which app would you like?

15. © Cambridge Silicon Radio 2010
Creates a rich UI for simple devices
 Once installed the user can configure the accessory using
a simple UI
– The device can have a lot more capability without a complex UI
– E.g. Set User names and Ids for multiple users

16. © Cambridge Silicon Radio 2010
One device can be used for many services
 Once connected the accessory can have access to web
information and services
– Fitness training
– Weight management
– Chronic disease management

17. © Cambridge Silicon Radio 2010
Web connected accessories
 Once set up the accessory will have the power of the web

18. © Cambridge Silicon Radio 2010
Web connected accessories
 Once set up the accessory will have the power of the web
 A weight scale is now part of your personal Health
management service

What opportunities does this create?

20. © Cambridge Silicon Radio 2010
Revenue opportunities
 The mobile maker doesn't need to understand the
applications
 The accessory maker doesn't need to understand the
applications
 The app developer can create powerful health and fitness
services with engaging user experience
 Generate new revenue for each provider
– Network operator – services, and loyalty
– Innovator – apps
– Handset maker – higher margin and loyalty
– Accessory maker – hardware (app share)
