The signal isn’t directed to a specific end user device. It’s broadcasted out in a dome around the Access Point (AP), the client device then receives the radio waves, then sends out its own it the same dome shape for the AP to receive.
WiFi is transmitted on either the 2.4 GHz or 5 GHz radio wave frequency.
