Abstract: A device is provided, which includes radio-frequency circuitry and an encoder. The encoder is configured to modulate input data to generate a long-range packet, and to transmit the long-range packet to a receiver through the radio-frequency circuitry. The long-range packet includes a long-range signal field (LR-SIG) and a long-range data field (LR-DATA). Each modulated bit in the long-range signal field and the long-range data field is spread into a plurality of spread modulated bits that are distributed into a plurality of symbols in a frequency domain.
