“…The femtocell operating scenario was retained. The channel sounder in [17] was used with a 500 MHz channel bandwidth and 1.2 kHz repetition rate to log a total of 30 data points covering line of sight, as well as one and two brick walls. The measurements are limited to a maximum of 33 m, due to the physical restrictions imposed by nearby buildings.…”

“…We derive a model that incorporates indoor signal attenuation as a key parameter, and also investigate the channel shadowing parameters, where results are conveniently obtained as a consequence of using the SVD method. We validate our proposed empirical models against those in [13] and against independently measured path loss data using the University of Durham's channel sounder described in [17].…”

“…The VNA can be employed in indoor measurements where the channel characteristics are assumed to be time-invariant for the duration of the sweep, or for CW measurements for the evaluation of narrowband transmissions. Wideband measurements with a large number of frequency samples requires long sweep times and can lead to a dispersed response due to movement [9]. In addition to the duration of the sweep, VNA's require the use of long cables since both the transmitter and receiver need to be connected to the same unit which reduces the range of the measurement or require an external amplifier to compensate for cable loss.…”

“…A custom designed sounder on the other hand can use separate transmitters and receivers and allow for outdoor cellular measurements as well as outdoor to indoor measurements and between floors. Such sounders use two different types of waveforms: continuous waveform with a Pseudo-Random Binary Sequence (PRBS) [41][42] [50] and frequency modulated continuous wave (FMCW) [9][51] [52]. Using a sliding correlator in a PRBS sounder or a heterodyne detector at the receiver in a FMCW sounder compresses the bandwidth of the detected signal thereby alleviating the data acquisition requirements.…”
