Olika typer av lokaliserings tjänsterRTLS vs. Conventional RFID

• Passive RFID - Short Read Range Identification Technology• Chokepoint-based• More data than barcode, easily readable, becoming inexpensive• Standardized (EPC Global )• Primarily an identification resource – not for location tracking.

• Active RFID - Location Tracking – Point Solutions • Use portals/scanners as overlays to existing LAN/WLAN • No standards proprietary networks• Various frequencies, tags & vendors create incompatible silos• Varying levels of performance, scalability and accuracy

• RTLS - Location Tracking – Leverage 802.11 coverage• Real-time enterprise-wide location tracking• Proprietary overlay systems over 802.11 networks• Open standards 802.11-based leverages WLAN infrastructure

Cons:

• Devices require client

• Not suitable for low cost, simple devices

• Requires calibration of Location Server

• Requires transport of location info over WLAN network

Asset Tracking & Management

Start on high-return, location-aware applications for tracking assets, personnel and patients.

Use of Radio Frequency Identification (RFID) capabilities, integrated with mobile communications, inventory solutions and directory applications, to track the location of assets, patients and clinicians.

Solution Benefits

• Improve efficiency through better utilization

of assets and resources.• 40% Reduce Asset Loss/ theft and 10% less inventory. 25% reduced rental costs.• Streamlining Patient Workflow by 15%-20%• Enhanced Patient & Clinician Safety

17

• Determine efficiency by recording the movement of assets & people

• Increase efficiency and safety/security through automated alerts based on location

• Provide new revenue-generating services to some verticals (such as “track my child”, …)

Asset Tracking solution

• Ekahau Finder/Tracker Application or IBSS provides a holistic view of the current placement of assets, inventory or people at any time on map-based software

• Ekahau Tags, Badges or Clients are used to identify assets, inventory or people to be tracked

• Location Clients can be placed on many different wireless devices, including: Nortel Wireless VoIP Handsets, handheld RFID or barcode scanners, PDAs, and laptops

• UC integration – click to call from GUI, generate UC-based event messaging based on business rules

Clinical Alarms & Alerts

A full-solution approach that manages the broad variety of notifications and delivers them effectively to mobile devices.

Sends event-driven alarms and alerts instantaneously to the right clinicians based on their role, the skills required and the clinician’s proximity to the location where the skills are needed.

Solution Benefits• Improved care and staff efficiency

through real time delivery of clinical alerts to mobile staff handsets.

• Effective communication between clinician

• Efficient response to care requirement • Enhanced Patient & Clinician Satisfaction

27

• Improve response to out-of-bounds conditions

• Save time & increase staff efficiency

• Improve workflow, performance & operations

• Automate recording of audit trail for performance analysis

Event Processing: Clinical Alarms/Alerts

• Wireless VoIP handsets are leveraged to enhance response

• Integration of various systems that monitor state or condition and with systems that control output

• Event Processing and Alarm Manager software drives alerts and information from monitoring devices to the right member of staff on their device of choice

• UC integration generates UC-based event messaging based on business rules; automates creation of click-to-call options to respond to events

Automated alerts are generated from monitoring devices to improve efficiency and response

Registered staff

Alarm Manager (Emergin, Comtech, …

1. Monitoring device detects out-of-bounds condition, an alarm is triggered & sent to Alarm Manager

2. Alarm Manager determines distribution of alarm, and sends alarm message to staff WLAN handset

3. Staff member’s WLAN handset rings, a text message is displayed indicating problem

4. Staff member can decide to accept, reject or phone the location where the alarm was generated; if not accepted, an alternate responder is contacted according to rules defined on alarm manager

Clinical Alarms & Alerts Example: Patient Monitor Alarm to WLAN Handset(s)

Alarm Manager

WLANAccess Point

1. Patient Monitor detects an out of bounds condition

2. An alarm is triggered

3. Patient Monitor sends alarm message

to Alarm Manager

4. Alarm Manager determines distribution of alarm. Sends alarm to

attending nurse’s WLAN handset

5. Attending Nurse’s WLAN handset rings and a text

message is displayed indicating problem and monitor the alarm was sent from. Nurse is busy

and does not accept the alarm

6. After a preset time the alarm rings the charge

nurse’s WLAN handset. Alarm accepted.
