Systems and methods for wireless communication in sub gigahertz bands

A method for wireless communication, comprising:

• receiving a wireless signal comprising a packet, at least a portion of the wireless signal being received over a bandwidth lower than or equal to 1.25 MHz, wherein the packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones, the thirty-two tones corresponding to frequency subcarriers within the bandwidth, and wherein the thirty-two tones of the at least one OFDM symbol are allocated as:
• twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone;
• and
• evaluating the wireless signal, the evaluating comprising converting the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.
