An area coverage of 4×4 MIMO-OFDM system was measured in residential home environment at 5GHz band. A novel spatial scanner was fabricated to suit the needs of measurements in environments with household furniture such as beds, sofa and tables. The coverage was calculated based on a total of 55,000 spatial samples in an area of 150m2 which includes two rooms, a hallway and living and dining areas. The results shown that the 4×4 MIMO system can greatly increase the area coverage compared to SISO system, especially at high data rate. It was also found that the introduction of optimum power allocation in the MIMO system is effective to increase area boundary with lower data rate.
