We　proposed　a　bidirectional60　GHz　multiband　orthogonal　frequency　division　multiplexing　(MB-OFDM)　wireless　communication　system.　In　this　system,　MB-OFDM　signals　can　be　transmitted　bidirectionally　on　60　GHz　band.　We　measured　the　transmission＇s　packet　error　rate　(PER)　of　the　system　in　different　distances　(1m-5m)　and　modes　(data　rates　of　53.3　Mbps　to　480　Mbps;　using　various　MB-OFDM　time-frequency　codes　(TFC))　to　show　the　system＇s　transmission　performance.　Furthermore,　we　demonstrated　the　system　with　the　form　of　teleconference　based　on　Ethernet.
