Sabre 1555 RFID & Bar Code Reader Programmer’s Reference Manual

Tag Filter Function
User-specified groups within a population of tags can be selected, read from, and/or
written to using the tag filter function commands.
Read/Write Performance
Read/write performance varies with RFID inserts, tags, and frequency configurations.
Read/Write Ranges
Write ranges are approximately 70% of the effective read ranges of the RFID inserts.
Read Range Examples
Read ranges are shown in Table E-4 for RFID inserts using frequency-hopping FCC
unlicensed operation reader and free space dipole tag.
For both the 2450- and 915-MHz units, the partial read zone is most affected by
environmental conditions (i.e., obstructions, metal structures), equipment factors (i.e.,
type of tag, number of tags), and variation from unit to unit.
The RFID tag read ranges for the 2450-MHz unit are shown in Figure E-1.
