5. RTLS – what’s in it for Biomed?
1. Increased productivity
– Shortening time to find assets for preventive maintenance and clinical use purposes
2. Increased asset utilization
– Knowing where a hidden item is for patient use
– Help determine of an item is in use
3. Reduce overtime
– Knowing where equipment is for PM’s increase productivity and reduce overtime
– Help with recalls
4. Help manage work flow more efficiently

8. Patented RSSI Modeling Approach for Indoor Positioning
1. Active measurements of all
RSSI data from each access
point is taken via Wi‐Fi Site
Survey. RF characteristics
such as multi‐path
reflections are recorded and
do not harm signal
measurement or location
accuracy.
2. Site survey data is stored in
the location server
3. Based on the site survey
data and the information
received from the tag/client,
the server software
calculates the real‐time
location using the patented
probabilistic algorithms.
Ekahau patent status in April 2009: nine patents approved worldwide, six pending
