2. Philadelphia, May 2–4, 2005 www.locationintelligence.net Agenda Is there a business case for local area Location Based Services (LBS)? –Case study: ROI for Hospital Asset Tracking How do you add location awareness to a local area in a cost effective way? –Wi-Fi based LBS

3. Philadelphia, May 2–4, 2005 www.locationintelligence.net Local Area LBS Case Study: The ROI of Asset Tracking in a Health Care System Improve workflow & efficiency Reduce costs Eliminate over investment Where is the equipment?

4. Philadelphia, May 2–4, 2005 www.locationintelligence.net The ROI benefit numbers for Asset Tracking in a hospital Reduced equipment purchase: 10%$150,000 Reduced equipment rental: 15% $60,000 Reduced maintenance/support labor: 10% $40,000 Reduced clinical labor: 2%$150,000 Improved hospital workflow: 1-2%$200,000 Improved employee satisfactionsoft Improved patient satisfactionsoft Improved quality of care (could develop hard est.) soft Improved regulatory compliance (could develop hard est.) soft ------------ Annual benefit$600,000 ** ======= ** Numbers are conservative values drawn from US hospital systems with 250-500 beds Payback period typically less than 1 year

5. Philadelphia, May 2–4, 2005 www.locationintelligence.net Options for local area LBS Use the same technologies used in the wide area e.g. GPS, Cellular network based –Not really suitable due to poor availability and accuracy Use a specialized radio network designed solely for Location determination –Portal/Choke-Point based, and/or –Full area continuous…Real Time Location System (RTLS) –Tend to be costly and single purpose Add location awareness to a radio network you already have deployed e.g. Wi-Fi

6. Philadelphia, May 2–4, 2005 www.locationintelligence.net Wi-Fi networks can now support data, voice & location 802.11 WLAN Infrastructure DATAVOICELOCATION Data AppsLocation Apps Voice Apps e.g., Physician Order Entrye.g., VOIP “Badges”e.g., Asset Tracking

7. Philadelphia, May 2–4, 2005 www.locationintelligence.net Why use Wi-Fi for local area LBS? Because you get to leverage the single infrastructure cost for multiple services… data, voice & location. –So, the marginal cost of adding Location is very low Because location will become an “equity of the network” in 2005 and beyond as the WLAN infrastructure providers make location available as a feature of their offerings Because Wi-Fi is getting better all the time…a/b/g…i/e/r…k/v…n…the alphabet goes on!

8. Philadelphia, May 2–4, 2005 www.locationintelligence.net The underlying techniques for adding location awareness to Wi-Fi Not currently available in Wi-Fi Available in Wi-Fi Currently available in Wi-Fi only using proprietary hardware. Expected to standardize in next few years 802.11k adds location report to MAC

9. Philadelphia, May 2–4, 2005 www.locationintelligence.net Use RF Power to determine location based on empirical survey or theoretical model AP 2AP 3AP 5 Location 1-48-35-60 Location 2-61-50-40 -35 -60 -48 Location 1Location 2 AP 3 AP 2 AP 5

10. Philadelphia, May 2–4, 2005 www.locationintelligence.net The components of a Wi-Fi LBS solution… just add software! Applications Asset Tracking, People Tracking, Yard Management Middleware Determines location or receives feed from network Supports complementary location providers e.g. Passive RFID Readers NO additional readers…just use the Wi-Fi APs Track-able devices Wi-Fi devices e.g. PDAs, Laptops, Active Tags

11. Philadelphia, May 2–4, 2005 www.locationintelligence.net Summary There is a significant business case for deploying LBS in the local area –Intra-Enterprise Asset Tracking is one example of a key category of local area LBS Apps Standard Wi-Fi infrastructure can be enhanced to provide location through the simple addition of software Wi-Fi Active Tags can be affixed to items that are not 802.11 enabled so almost anything is locatable
