Described herein are systems and techniques related to maintaining wireless connections between stations (STAs). A message is communicated between the STAs to anticipate modulation type that may be used in transmitting a packet under the Wireless Gigabit alliance (WiGig) specification and the Institute of Electrical and Electronics Engineers (IEEE) 802.11ad standard. The message may be used in disabling or enabling automatic gain control (AGC) at a receiving STA end.
