Varför RTLS?
• Leverage WLAN infrastructure with Wi-Fi-based asset/personnel
tracking and location applications
• Fast locating of tagged equipment improves core services
• Location context for workflows makes business operations and
processes more efficient
• Locating lost or missing equipment saves money
• Preventing theft reduces cost

Olika typer av lokaliserings tjänster
RTLS 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

less inventory. 25% reduced rental costs.
• Streamlining Patient Workflow by 15%-20%
• Enhanced Patient & Clinician Safety
16
Asset Tracking solution
Leverage the WLAN network to provide real-time
location & status of assets, inventory, & people
• 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 UCbased event messaging based on business rules
• 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”, …)

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
26
Event Processing: Clinical Alarms/Alerts
Automated alerts are generated from monitoring
devices to improve efficiency and response
• Improve response to out-ofbounds conditions
• Save time & increase staff
efficiency
• Improve workflow, performance
& operations
• Automate recording of audit trail
for performance analysis
• 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
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

5. Attending Nurse’s WLAN
handset rings and a text
message is displayed indicating

and does not accept the alarm
3. Patient Monitor sends
alarm message to Alarm
Manager
2. An alarm is
triggered
1. Patient Monitor
detects an out of
bounds condition
6. After a preset time the
alarm rings the charge
nurse’s WLAN handset.
Alarm accepted.
