Abstract:
An extensive 4×4 MIMO channel measurement is carried out at 6.0-6.4 GHz under a typical classroom environment with channel sounder based on vector network analyzer. Both LOS and NLOS scenarios are considered. The results on path loss, delay spread and spatial correlation are presented. The measurement shows that, for corridor coverage, 2×2 MIMO is more economical than 4×4 MIMO due to high correlation. In order to identify the unique characteristics at the high frequency band, the measured channel parameters at 6.0-6.4 GHz are compared with those at 2.45 GHz. The comparison shows that the shortened wavelength of this higher frequency band results in a great difference of channel characteristics. Therefore, our measurement results provide new guidance for the design and development of the system working on 6.0-6.4 GHz band.
Key words: 6.0-6.4 GHz, multi-input multi-output (MIMO), channel measurement, channel characteristics
