Multifrequency Wireless Channel Measurements and Characterization in Large Indoor Office Environments

On the Road to 6G: Visions, Requirements, Key Technologies, and Testbeds

“…At the Tx side, a single omnidirectional antenna was used for all frequency bands channel measurements. In [537], a time domain channel sounder was used to conduct SISO and MIMO channel measurements in a large indoor office environment. For SISO channel measurements, two omnidirectional antennas were used as the transmitting and receiving antennas.…”

“…The ISAC channel sounders consist of two parts: communication channel sounding and sensing channel sounding. In [555], the authors conducted SISO and MIMO channel measurements in a mechanical and automobile workshop. The height of the Tx antenna is 4.5 m, which is approximately the height for the placement of wireless access points.…”

“…The height of the Rx antenna is 0.3 m and 1 m to simulate the communication scenarios of the auto guided vehicle and wireless switches. The detailed description of the time-domain channel sounder can be referred to [537]. In [556], a sensing channel measurement was conducted in an anechoic chamber by a THz ISAC channel sounder to verify the imaging accuracy of the sensing channel.…”
