Real-time Locator System (RTLS):

 

A technology where inventory containers, such as a pallet, are tagged with an “active’ RFID tag (meaning a tag with a battery that regularly broadcasts its identification). Labor and equipment can also be tagged. A series or readers collect those signals and triangulate them to identify the asset’s location. This can be useful if the WMS supports minimizing aisle congestion, identifying the right asset to assign a task to based on proximity, and/or to make sure the correct worker is interacting with the correct mobile robot through a “pairing” function using the RFID tags.
