Claim Text:
1. A device usable to facilitate, at least in part, wireless communication, the device comprising: logic that comprises hardware, the logic to generate, at least in part, a preamble of a protocol data unit usable in the wireless communication, the protocol data unit to comprise the preamble and data; the preamble comprising a repeated short training field; the preamble also comprising a repeated long training field to follow the repeated short training field; the preamble further comprising one or more signal fields that follow the repeated short training field; the wireless communication, when in operation, to have a bandwidth of 1 megahertz and to use orthogonal frequency division multiplexing; the repeated short training field comprising two short training field repetitions; the repeated long training field comprising two long training field repetitions; each of the two repeated short training field repetitions and each of the two repeated long training field repetitions comprising a respective plurality of symbols; the two repeated short training field repetitions and the two repeated long training field repetitions to permit detection at the bandwidth of 1 megahertz; wherein: at the 1 megahertz bandwidth of the wireless communication, the repeated short training field and the repeated long training field, as transmitted, are to have first respective durations; at another bandwidth of the wireless communication that is greater by a factor of N compared to the 1 megahertz bandwidth, the repeated short training field and the repeated long training field are to have other respective durations that are decreased compared to first respective durations by the factor of N.
