Why We Are Great at What We Do ?• Leveraging an 802.11 network has obvious advantages to solutions that require a

proprietary infrastructure, however, enterprise WLANs are complex and fluctuating entities.

• Ekahau has 10 apprpved patents on generating location from RSSI data.– US 7,228,136: A method for probabilistic positioning using radio signal observations. – US 7,196,662: A method for creating and combining probabilistic radio signal models. – US 7,209,752: Methods for estimating and visualizing positioning uncertainty. – US 7,299,059: A method for modeling possible routes using tracking rails to improve

positioning accuracy. – US 7,149,531: A method for monitoring radio networks in real time. – US 2005/0136944: A method for improving positioning accuracy by using a sequence

of radio signal observations. – US 2005/0181804: A method for normalizing radio signal observations from different

types of devices. – US 2007/0149216: A method for multi-hypothesis tracking which improves

positioning accuracy, scalability and performance. – US 2007/0149215: A method for improving positioning system performance by

focusing the computation on a small subset of possible locations based on the latest observations.

Why Hospitals need Asset Tracking

Ekahau Confidential

RTLS – What do people think it is ? What’s out there ?

• Real Time Location System• Monitor location of objects

using a radio network• Rules and alerts based on

location or button presses• API to 3rd party system

pushes out location data or even a map

…this is pretty easy, not very impressive nor exciting…

What is it really about ?

RTLS is not only about location and eventsIt is about:

• Providing and communicating relevant information to and from people and objects

• Communicating one to many, many to one, tag to person, tag to tag, person to tag, etc.

• Driving actionable events which are communicated and/or escalated and responded to based on event, severity, type, time, motion, location, sensor, etc.

• Events initiated by tags, buttons, sensors, people, computers, telephones, PDA’s, cell-phones, etc. all forming the “RTLS Grid” that communicates.

Ekahau Zones

• Ekahau Zones are the equivalent of physical portals, but exist virtually in the Ekahau system to drive alerts and business rules.

• Ekahau Zones are drawn by mouse and can be located anywhere on a facility map.

• There is no limit number, size or shape on zones.

• Example zones include– Doorways for exit alerts– Patient rooms for room status– Sending rooms for Clinical Engineering– OR/ED Flow Tracking

• Zero cost alternative to expensive and proprietary chokepoints *) at doorways or exits. *) some WIFI chokepoints operate at 125 kHz which have been found to pose serious risks in hospitals. Alert COW

Ekahau Location Beacons – Complementing Wi-Fi

• The beacons can be attached to any surface and pointed into the area that needs to be identified. For example:– A Bed Beacon on the wall above a

bed, will shower the bed with a unique ID, allowing you to see if a patient is in the bed or not or if a caregiver is or has been with a patient.

– A Bed Beacon can tell whether a bed is available or not based on occupancy

– A Bed Beacon mounted over a sink can detect who washed their hands and when

– Beacons can be used between curtained areas to know the location and status of patients for example in recovery, ED etc.. Patient Smith in Bed 1

What else can Wi-Fi RTLS do for my hospital ?

• An RTLS system is not just limited to “finding things” or alerting when something exits the door, a properly planned deployment and execution can automate many manual processes and reduce human error. Examples include:– Managing and automating equipment inventories, par

levels, preventive maintenance– Automatically capture time and motion for outpatient

visits, surgeries, lab procedures etc. to measure and manage based on process visibility.

• A properly deployed RTLS system can be used across the entire enterprise and leverage the economies of scale of hospital-wide implementations on a “cost per tracked item” model.

Ekahau Confidential

Summary

• Ekahau is the only solution on the market that does not require wiring in or plugging in disruptive, expensive and proprietary hardware technology – we accomplish all of this with software and tags.

• Because Ekahau is 100% Wi-Fi and IP-based:– You don’t have to worry about any potential interference issues now or

in the future.– The learning curve and on-going support for Ekahau RTLS is minimal.

• Ekahau offers several business models to accommodate your purchasing requirements from simple capital purchase to “lease to own” and SaaS.

• Our confidence in our technology is backed by a thorough pre-survey followed by a fast system implementation and comprehensive End-User training.

Case Study : Infection Control

Customer:• XXX Bed Hospital in Europe• 800,000 sq.ft. facility with 95% Wi-Fi

coverageProblem:

• HAI ( Hospital Acquired Infections) are believed to be a significant problem due to the inadequacy of hand washing.

• HAIs are seen as occurring in 5-8% of patients resulting in approx $4k in increased costs per affected patient = possibly $12m per year ( 30k discharges)

Solution:• Ekahau T-301BD tags and Ekahau

Location Beacons monitor and report hand washing events compared to patient interactions.

• Remind care givers via gentle text reminders on staff badges to sanitize hands after each patient contact

• A 5% reduction in HAIs due to proper hand sanitization pays for the RTLS system and more.
