<P>PROBLEM TO BE SOLVED: To provide a broadcast transmission technique which can reduce a probability of repetitively-occurring transmission collision. <P>SOLUTION: A system includes a sequence selection module and a plurality of emission elements. The sequence selection module selects sequences of directivity transmission patterns (702, 706), and each of the selected sequences corresponds to a period. The plurality of emission elements wirelessly transmit a broadcast with the period of the selected sequence (704, 708). The broadcast includes, for example, beacon and/or data broadcast and/or control broadcast and/or management broadcast. <P>COPYRIGHT: (C)2010,JPO&INPIT |
