Table 2: Performance Metrics
Performance Tuning Options
This section provides a set of options, based on high-level usecase characteristics,
allowing the reader performance to be optimized.
Table 3: Performance Tuning Options
Setting Description
Unique Tag Count Total number of unique tags found.
Total Tag Count Total number of tags read, including re-reads of the same tag. Also displays the
time during which those tags were read.
ReadRate/Sec Using the Total Tag Count metric, displays the average tags per second.
Setting Description
Read Power Control the amount of RF Power transmitted by the reader, to the antenna,
when reading. The RF power directly relates to the range at which the
reader can “see” tags, the higher the power, the longer the range.
Tag Population
Size
• Automatically adjust settings as tag population changes - Reader
dynamically adjusts optimization setting depending on the tag population it
detects in the field.
• Optimize for estimated number of tags in the field- If the tag population
size is relatively well known and consistent, performance can be increased by
optimizing for that size. In this case enter the approximate population size for
increased performance.
Read Distance vs.
Read Rate
• Maximum tag read rate - Performance is optimized for maximizing the speed
of tag to/from reader communications, which results in more tags being read
faster. OR
• Maximum Tag read distance - Performance is optimized for reading weaker,
harder to read tags.
Note: Mostly applicable to using Battery Assisted Passive Tags. Most Passive
Tag applications are range limited by the power output from the antenna,
not the reader's ability to "hear" a tag's response.
