9.6 RTLS Overview
Ekahau RTLS (Real Time Location Service) tracks battery-powered Wi-Fi tags attached to APs managed
by the Zyxel Device to create maps, alerts, and reports.
The Ekahau RTLS Controller is the centerpiece of the RTLS system. This server software runs on a Windows
computer to track and locate Ekahau tags from Wi-Fi signal strength measurements. Use the Zyxel
Device with the Ekahau RTLS system to take signal strength measurements at the APs (Integrated
Approach / Blink Mode).
The following example shows the Ekahau RTLS Integrated Approach (Blink Mode).
1
The Wi-Fi tag sends blink packets at specified intervals (or triggered by something like motion or button
presses).
2
The APs pick up the blink packets, measure the signal strength, and send it to the Zyxel Device.
3
The Zyxel Device forwards the signal measurements to the Ekahau RTLS Controller.
4
The Ekahau RTLS Controller calculates the tag positions.

9.6.1 What You Can Do in this Chapter
Use the
RTLS
screen (
) to use the managed APs as part of an Ekahau RTLS (Real
Time Location Service) to track the location of Ekahau Wi-Fi tags.
9.6.2 Before You Begin
You need:
• At least three APs managed by the Zyxel Device (the more APs the better since it increases the
amount of information the Ekahau RTLS Controller has for calculating the location of the tags)
• IP addresses for the Ekahau Wi-Fi tags
• A dedicated RTLS SSID is recommended
