在5GHz频段的家庭环境中，对4 × 4 MIMO-OFDM系统的区域覆盖进行了测量。为满足在有床、沙发、桌子等家具的环境中进行测量的需要，研制了一种新型的空间扫描仪。覆盖率的计算是基于150平方米的区域内总共55，000个空间样本，其中包括两个房间，一个走廊以及起居和用餐区。结果表明，与单输入单输出系统相比，4 × 4 MIMO系统可以大大提高系统的覆盖范围，特别是在高数据速率下，在MIMO系统中引入最优功率分配可以有效地增加低数据速率下的区域边界
An area coverage of 4times4 MIMO-OFDM system was measured in residential home environment at 5 GHz 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 150 m2 which includes two rooms, a hallway and living and dining areas. The results shown that the 4times4 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
