The technological issues such as 100% reliability can be achieved by: (1) installing multiple antennas with different orientations per reader, (2) customizing the tag and antenna design for each material type and (3) installing multiple readers to increase readability of the tags.
The UWB utilizes multiple readers to identify the location of tags, but it requires careful installation of these readers at known locations.
The answer is that there are restrictions on the maximum output power of the readers that limit their interrogation zones, requiring multiple readers to cover the area [17].
As RFID technology matures, and pervades different aspects of our lives, the operation of multiple readers in proximity to each other is expected to grow significantly.
To evaluate the handling of multiple readers in imaging diagnostic accuracy systematic reviews-meta-analyses.
The deployment of multiple readers in close proximity brings forth new issues as well.
The prospect of multiple readers in an area operating in synchronized fashion using the same queries raises the question: Why not just use one reader with large enough power to read all tags in the area?
In the BLSync protocol, overlapped tags enjoy a better chance of being read and acknowledged since they could be read in the frames of multiple readers at the same time.
The solution of using synchronized multiple readers in a large area could be equivalent to use a single reader with a larger power, but the restriction in the maximum power allowed to the readers limits their interrogation zones, requiring for multiple readers to cover the area [34].
