The RFID “Strike Zone”

During a recent RFID asset tracking project I was talking with a client about how we would set up a system to identify items stored within a secure warehouse cage as they were transported though a doorway. Items would sometimes be carried by hand, and at others brought through using a common pushcart.

In explaining how we would set up the required reader and antennas, I came upon a great visualization that everyone understood. The strike zone.

In the client’s scenario, the items to be tracked and the employee’s badge on a lanyard were tagged with UHF gen 2 tags. In this, and most similar situations, all of the tags of interest would be somewhere between shoulder and knee height. This included the ID badge, a hand carried item, or an item transported on top of or on the lower section of a transport cart.

Now, whenever I explain a similar RFID system to a client, I refer to the “Strike Zone” and the concept is immediately understood.

As a Baltimore O’s fan, these days it seems easier to find the “Strike Zone” for an RFID implementation than it does finding the strike zone over home plate at Camden Yards!
