PPROBLEM TO BE SOLVED: To transmit multicast data in a wireless section fast with high quality. PSOLUTION: A wireless access point (master unit) 12a discriminates, based on an assignment request from a wireless adapter (slave unit) 21a, whether the slave unit 21a is multicast-enabled or not. If it is multicast-enabled, as a result of the discrimination, a MAC address is exchanged and registered between the master unit 12a and the slave unit 21a. Multicast data sent from a host 11 to the master unit 12a via a first communication protocol 13 are converted into a WDS frame format. This converted radio frame is transmitted from the master unit 12a through a radio section 40 to the slave unit 21a. In the slave unit 21a, the multicast data are converted into the original frame format and transmitted to terminals 21-1 to 22-n via a second communication protocol 23. PCOPYRIGHT: (C)2007,JPO&INPIT
