Chapter 9 Wireless
ZyWALL/USG Series User’s Guide

9.6.1 What You Can Do in this Chapter
Use the RTLS screen (Section 9.6.3 on page 257) 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 ZyWALL/USG (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
• Ekahau RTLS Controller in blink mode with TZSP Updater enabled
• Security policies to allow RTLS traffic if the ZyWALL/USG security policy control is enabled or the
Ekahau RTLS Controller is behind a firewall.
For example, if the Ekahau RTLS Controller is behind a firewall, open ports 8550, 8553, and 8569 to
allow traffic the APs send to reach the Ekahau RTLS Controller.
The following table lists default port numbers and types of packets RTLS uses.
9.6.3 Configuring RTLS
Click Configuration > Wireless > RTLS to open this screen. Use this screen to turn RTLS (Real
Time Location System) on or off and specify the IP address and server port of the Ekahau RTLS
Controller.
