Association request: Carries information about the connection including SSID.
Beacon frame: Sends periodically from an Access Point to announce its presence and provide the SSID and other preconfigured parameters.
Probe request frame: Sends from a wireless client when it requires information from the wireless network.

Match the frequency channel saturation avoidance technique used.

Sort elements

Direct-sequence spread spectrum (DSSS)
Orthogonal frequency-division multiplexing (OFDM)
Frequency-hopping spread spectrum (FHSS)
Frequency Modulation
Pulse Modulation

The technique creates redundancy in the transmitted signal in an effort to counter quality loss in the wireless medium.
This technique is able to maximize spectral efficiency without causing adjacent channel interference.
This technique requires the sender and receiver to be synchronized to “know” which channel to jump.
