Abstract
Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz and lower frequency bands. In many embodiments, physical layer logic may implement a new preamble structure with a new signal field. Embodiments may store the preamble structure and/or a preamble based upon the new preamble structure on a machine-accessible medium. Some embodiments may generate and transmit a communication with the new preamble structure. Further embodiments may receive and detect communications with the new preamble structure.

31. An apparatus, comprising:
-
at least one memory; and logic, at least a portion of which is in hardware, the logic to detect a preamble in a physical protocol data unit (PPDU), the PPDU to correspond to a below 1 GHz frequency band transmission, the PPDU to comprise a plurality of orthogonal frequency-division multiplexing (OFDM) symbols, the preamble to comprise a signal field comprising a bandwidth parameter to designate a bandwidth of the PPDU, the designated bandwidth to correspond to an Institute of Electrical and Electronics Engineers (IEEE) 802.11ac bandwidth reduced by a factor of 10, a data portion of the PPDU to be demodulated according to a first tone allocation that matches an IEEE 802.11ac tone allocation for the IEEE 802.11ac bandwidth.

46. At least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed on a computing device, cause the computing device to:
detect a preamble in a physical protocol data unit (PPDU), the PPDU to correspond to a below 1 GHz frequency band transmission, the PPDU to comprise a plurality of orthogonal frequency-division multiplexing (OFDM) symbols, the preamble to comprise a signal field comprising a bandwidth parameter to designate a bandwidth of the PPDU, the designated bandwidth to correspond to a second bandwidth reduced by a factor of 10, a data portion of the PPDU to be received according to a first tone allocation that matches a tone allocation corresponding to the second bandwidth.
