Patent ID: 8798033

Claim:
A local area wireless communication apparatus, comprising: two or more local area wireless communication units configured to transmit broadcasting signals to a local area through two or more radio frequency (RF) channels and to communicate communication signals with one or more user terminal apparatuses located in the local area through one RF channel of the two or more RF channels, wherein the broadcasting signals are unidirectional signals to the one or more user terminal apparatuses and the communication signals are bidirectional signals to and from the one or more user terminal apparatuses; and a controller configured to synchronize two or more broadcasting frames for the broadcasting signals allocated onto each of the two or more RF channels on a time axis, and, when one bidirectional communication frame for the communication signals has been allocated onto the one RF channel of the two or more RF channels, to allocate other bidirectional communication frames for the communication signals onto other RF channels of the two or more RF channels to thereby synchronize the allocated other bidirectional communication frames with the one bidirectional communication frame on the time axis.
