Embodiments described herein provides a system for detecting data received in a low power low rate (LPMR) data frame format. The system includes a receiver and control circuitry. The receiver is configured to receive a data frame comprising an LPLR preamble portion and an LPLR data portion following the LPLR preamble portion. The LPLR preamble portion and the LPLR data portion occupy a bandwidth that is less than an allowed bandwidth. The control circuitry is configured to determine a mode of the data frame based on whether the data frame has an additional portion, and detect data field in the LPLR preamble portion from the data frame based on the mode of the data frame.
