SUMMARY
A Wi-Fi client, such as a laptop or smartphone, transmits a "Probe Request Frame" prior to associating with an Access Point (AP). This frame is used to discover nearby APs and is dependent on the Network Interface Card (NIC) driver settings regarding transmission frequency. The inquiry confirms that clients do indeed send out signals before establishing a connection with an AP, contrary to the initial suspicion that they do not transmit anything.
