Behind the Door: Practical Parameterization of Propagation Parameters for IEEE 802.11ad Use Cases

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This is not an article but a communication.

The authors performed a series of propagation measurements in closed rooms.

These measurements raise many doubts. No information about materials present in the propagation path.

When examining the influence of people on propagation, at least the basic parameters should be provided, such as weight, height and gender. This affects the results obtained.

Why are physical phenomena such as diffraction ignored?

How the sidewalls of horn antennas were taken into account

How is the generator stability?

Reviewer 2 Report

Comments and Suggestions for Authors

The work presents a measurement campaign to assess the influence of directional antennas and presence of people at 60 GHz in an indoor scenario. The work is technically sound, it is well written, the quality of the figures is high, and the results are interesting. I have the following comments:

In section 4.1 the results of the static case are shown. However, in Table 1 results for the case with and without people are shown. Could you please clarify what is the configuration of the experiment explained in section 4.1.

In table 1 the difference between the angle of the LoS direction and the angle of the maximum received power is shown for the cases without people and with people. The presence of people affects to this difference, for example, for position 1 the difference is 103º when no people is in the environment and 25º when people is inside the scenario. What is the explanation for this fact?

Reviewer 3 Report

Comments and Suggestions for Authors

The paper presents an empirical measurement campaign of wireless channels within an office environment to assess power loss and angular distribution as an indoor base station serves indoor users, simulating the operation of an IEEE 802.11ad high-speed Wireless Local Area Network (WLAN) at 60 GHz. The focus of the study is on the impact of deviating from the LOS when using highly directional antennas. Additionally, the study explores scenarios with and without pedestrian movement in the vicinity of wireless terminals.

 

1. The authors should summarize the experimental setup and parameters and create a table for clarity.

2. It would be beneficial to include a Discussion section that addresses the issues and limitations encountered during the experiment, as well as suggestions for improvements. For instance, the paper does not discuss the impact of different materials' reflective characteristics or the effects of various shapes and sizes of obstacles on signal propagation.
