Claim:
1. 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, the first tone allocation to differ from a second tone allocation used for the preamble.
