<P>PROBLEM TO BE SOLVED: To provide a wireless LAN system in which packet transmission efficiency can be enhanced by removing the impact of radio wave interference reliably. <P>SOLUTION: The distribution order of a multicast packet or a broadcast packet at a wireless LAN access point is determined. When a multicast packet or a broadcast packet is received, it is stored temporarily, and the multicast packets or broadcast packets thus stored are distributed sequentially to a POS terminal under control according to the distribution order starting from the farthest wireless LAN access point. The distribution order of a multicast packet or a broadcast packet is determined for every wireless LAN access point or every combination of wireless LAN access points which do not interfere. <P>COPYRIGHT: (C)2012,JPO&INPIT |
