Abstract
With the increased resolution and frame rates of video recordings, in combination with the current evolution towards video-on-demand streaming services and the user expecting ubiquitous wireless connectivity, it is necessary to design wireless communication systems that allow high-rate data transfer. The large bandwidths that are available in the mmWave frequency band allow such high data rates. In this paper, we provide an experimental and simulated indoor residential radio channel model at V-band frequencies and perform packet error rate and throughput measurements at 60 GHz using IEEE 802.11ad transceivers. We compare the path loss and throughput measurements to simulations using a network performance prediction tool. The path loss measurement results using an omnidirectional transmit antenna correspond well to generic indoor mmWave channel models. Double-directional path loss measurements show that generic models underestimate path loss of non-Line-of-Sight (NLOS) links. A ray-launching algorithm is designed and validated, and used for IEEE 802.11ad throughput estimation based on link budget calculations. The link budget underestimates the achieved throughput, when comparing to adaptive-rate MCS selection in a commercial transceiver, based on the measured signal-to-noise ratio. Packet error rate measurements confirm that, even for NLOS links, throughputs exceeding 1 Gbps are possible.

Wireless connectivity has become essential in our daily lives, and as the amount of internet traffic exponentially increases, e.g., due to high-definition and high-framerate video streaming, there is a need for high-throughput wireless communication systems

Summary
Wireless connectivity has become essential in our daily lives, and as the amount of internet traffic exponentially increases, e.g., due to high-definition and high-framerate video streaming, there is a need for high-throughput wireless communication systems. Channel models at mmWave frequencies for indoor environments are presented in [9,10,11,12,13,14,15,16,17,18,19,20]. Path loss (PL) and delay spread of the 60 GHz radio channel of a hospital environment are presented in [13], and are found to be lower than for other indoor environments such as an office room. Spatial and temporal characteristics of the 60 GHz indoor radio channel are provided in [18,19], confirming that only first-order and second-order reflections form relevant multipath components. In [37], it is shown that furniture in a residential environment greatly impacts the channel
