This technique is utilized for examining wireless channel properties. Channel sounding is a popular field measurement technique for mmWave frequency bands as it is the instrument that provides an efficient impulse response or angular properties of the channel. The channel sounder is significant for mmWave-mMIMO channel modeling, test-bed, simulation and validation as it provides precise calibration, synchronism, resolution and susceptibility at reasonable system cost. The measurement requirements of the sounding approach depend upon the frequency and BW of the channel, the channel detection unit for multiple antennas, and whether the channel is static or dynamic to maintain the speed of the sounder.
Propagation Measurement-Based Wireless Channel Characterization and Modeling

In the design of digital wireless systems for operation with high-data rates, there is a need to not only know the transmission loss, but also the delay, frequency, and direction dispersion characteristics of the radio channels over which transmissions are planned. These characteristics are often estimated from measurements using test, or channel sounding, transmissions over radio channels typical of the type of channel associated with the wireless system of interest.

Work related to B-to-B channel analysis for UWB frequency range is carried out in Ref. [24,25,30–32]. B-to-B links for single-input-single-output (SISO) and multiple-input-multiple-output (MIMO) channels study have been reported in Ref. [30] using compact antennas. Textile-based cavity-backed substrate-integrated waveguide antennas have been studied for applications related to emergency and rescue [31]. B-to-B analysis in an anechoic chamber related to PL has been examined in the 2–8 GHz frequency using planar UWB antennas [24]. The impact of body mass index (BMI) has been studied in the 2–10-GHz frequency range using the MIMO array channel sounding system in an anechoic chamber to mainly capture variation in BMI effect on the propagation characteristics [32]. The study of B-to-B and off-B links over 5 m in an indoor environment is presented in Ref. [25] considering analysis related to various channel parameters.
