This disclosure describes systems, methods, and devices related to an optimized channel estimation field. A device may determine an enhanced directional multi-gigabit (EDMG) frame to be sent to a first device using a communication link. The device may determine a channel estimation field (CEF) associated with the EDMG frame, wherein the CEF is comprised of one or more orthogonal frequency division multiplexing (OFDM) symbols. The device may cause to send the EDMG frame to the first device.
