Performance-Oriented UWB RTLS Decision-Making Approach

Round 1

Reviewer 1 Report

This paper provides advanced guidelines for UWB RTLS selection. The review covers UWB-related literature. However, the reviewer has the following concerns.

1. The authors have not conducted real-world experiments to evaluate the performance of the proposed system. They should set up a test bed and compare the localization accuracy in this test bed.

2. To evaluate the performance of the tracking algorithm, the authors should also give qualitative results to validate the performance of the reviewed approaches.

3. What is the configuration of the trial in object tracking? Are the reviewed algorithms tested in the same trial site?

Reviewer 2 Report

The article concerns the application of UWB technology in RTLS. The subject matter is up-to-date and desirable. The article is correctly written, and the literature analysis is exhaustive.

In table 1, the type of data fields are empty.

In Table 2, the results should be consistent, most of them refer to accuracy in m, there are also dBm and cm. This should be clarified and where these units come from.

Subsection “4.3.4 Software that will use the data captured” seems redundant and does not contribute much.

A large part of the article is an analysis of the literature, the original authors' contribution seems to be smaller than the descriptive part. This can be seen especially in subsection 5, which should include the authors' observations of the work and not another literature review. The article should be redrafted in order to emphasize the original contribution of the authors of the work. In its current form, it is more like a review article.

Reviewer 3 Report

This paper proposed a new approach for selection of UWB RTLS. The paper itself is well organized and illustrated. The only problem is that I don't see how much this new approach would contribute to the selection. I mean, there's no "experiments" (which makes sense given the topic) and no comparison. Could you show me how this new method would help (with an example, maybe)?
