This paper deals with the development of 1.2 Gbps MIMO wireless LAN system based on IEEE802.11TGac's functional requirements. It reaches 33 meter propagation distance by using 80MHz of bandwidth on 5GHz band. 4 ? 5 antennas configuration contribute 2nd-order diversity gain and maintain both the high throughput and the high performance. The proposed Greenfield format preamble has high preamble efficiency. Novel phase rotation is employed to get low PAPR signal of preamble and data fields. Three different coding rates are examined for 64-QAM constellation which all accomplish over 1 Gbps with maximum throughput 1.266 Gbps.
