65. Wi-Fi Measurements

TEMS Investigation is capable of collecting Wi-Fi measurements using the PC's built-in Wi-Fi network card or an external Wi-Fi adapter plugged into the PC.

For TEMS Investigation to detect such a device, you need to check the Wi-Fi Network Card item in Device Detection Properties dialog (see section "Device Detection Properties") and then restart TEMS Investigation. The Wi-Fi device will then appear as an "EQ" of its own in the application.

There are no script activities or manual control commands for starting and stopping Wi-Fi measurements. Rather, as soon as you activate the Wi-Fi device, TEMS Investigation will start presenting data from it, populating the Wi-Fi information elements listed in IEs and Events, section "Information Element Table".

These elements appear in Wi-Fi presentation windows as indicated in IEs and Events, section "Wi-Fi Presentation Windows".

Please note that activating a Wi-Fi device in TEMS Investigation is independent of whether the device is connected to a Wi-Fi access point, or indeed whether it has its radio switched on at all.

An event "Wi-Fi Scan State" with extra information "On" is always generated when you activate a Wi-Fi device in TEMS Investigation. Naturally, in order to actually obtain Wi-Fi measurements, the device must be in an operational state and detect a Wi-Fi network.
