RFID Antenna
When attempting to utilize the RFID read functionality of the Falcon 5500 RFID unit it is important to note that the antenna is linearly polarized. This feature requires the tags to be similarly aligned in a planar field to optimize read range and efficiency.
Read Range
The Falcon 5500 RFID has a functional range of two to six feet. Greater read range distances are possible; however, efficiency and predictability of tag data collection will diminish beyond the recommended range. A reduction in func- tional range may result when attempting to read many tags simultaneously (several cases on a pallet) due to tag performance degradation. Tag perfor- mance will vary based upon class, application and environment.
Write, Kill, and Lock
Due to the emerging nature of RFID technologies, Write, Lock and Kill operations may sometimes behave erratically. Verifying the operation is strongly recommended, as the RFID module may not always return the correct status for these operations.
Proximity of Tags
Tags of similar antenna structure and size can obscure the ability to read multi- ple tags if they are “stacked” in the read plane. Multiple tag reading performs best when tags are spaced and positioned according to their intended use. A minimum of 4” spacing between tags is recommended.
Tag Types
•Class 0
•Class 1
•Class 1 Generation 2
PSC does not recommend or endorse a particular RFID tag type. It is recommended that you evaluate your environment and product to determine the optimum solution for your application.
