Support for location-based services

FortiOS supports location-based services by collecting information about WiFi devices near FortiGate-managed access points, even if the devices don’t associate with the network.

Overview

WiFi devices broadcast packets as they search for available networks. The FortiGate WiFi controller can collect information about the interval, duration, and signal strength of these packets. The Euclid Analytics service uses this information to track the movements of the device owner. A typical application of this technology is to analyze shopper behavior in a shopping center. Which stores do people walk past? Which window displays do they stop to look at? Which stores do they enter and how long do they spend there? The shoppers are not personally identified, each is known only by the MAC address of their WiFi device.

After enabling location tracking on the FortiGate unit, you can confirm that the feature is working by using a specialized diagnostic command to view the raw tracking data. The Euclid Analytics service obtains the same data in its proprietary format using a JSON inquiry through the FortiGate unit’s web-based manager interface.

Configuring location tracking

You can enable location tracking in any FortiAP profile, using the CLI. Location tracking is part of location-based services. Set the station-locate field to enable. For example:

config wireless-controller wtp-profile edit “FAP220B-locate” set ap-country US config platform set type 220B

end config lbs set station-locate enable

end

end

Automatic deletion of outdated presence data

The FortiGate generates a log entry only the first time that station-locate detects a mobile client. No log is generated for clients that have been detected before. To log repeat client visits, previous station presence data must be deleted (flushed). The sta-locate-timer can flush this data periodically. The default period is 1800 seconds (30 minutes). The timer can be set to any value between 1 and 86400 seconds (24 hours). A setting of 0 disables the flush, meaning a client is logged only on the very first visit.

The timer is one of the wireless controller timers and it can be set in the CLI. For example:

config wireless-controller timers set sta-locate-timer 1800

end

The sta-locate-timer should not be set to less than the sta-capability-timer (default 30 seconds) because that could cause duplicate logs to be generated.

FortiPresence push REST API

When the FortiGate is located on a private IP network, the FortiPresence server cannot poll the FortiGate for information. Instead, the FortiGate must be configured to push the information to the FortiPresence server.

Enter the following command:

config wireless-controller wtp-profile edit “FP223B-GuestWiFi” config lbs set fortipresence {enable | disable} set fortipresence-server <ip-address> Default is 3000. set fortipresence-port <port> set fortipresence-secret <password> set fortipresence-project <name> set fortipresence-frequency <5-65535> Default is 30. set fortipresence-rogue {enable | disable} Enable/disable reporting of Rogue APs. set fortipresence-unassoc {enable | disable} Enable/disable reporting of unassociated devices.

end

end

Viewing device location data on the FortiGate unit

You can use the FortiGate CLI to list located devices. This is mainly useful to confirm that the location data feature is working, You can also reset device location data.

To list located devices diag wireless-controller wlac -c sta-locate

To reset device location data diag wireless-controller wlac -c sta-locate-reset

Example output

The following output shows data for three WiFi devices.

The output for each device appears on two lines. The first line contains only the device MAC address and the VLAN ID. The second line begins with the ID (serial number) of the FortiWiFi or FortiAP unit that detected the device, the AP’s MAC address, and then the fields that the Euclid service uses. Because of its length, this line wraps around and displays as multiple lines.
