The Impinj Speedway xPortal Gateway RFID Reader incorporates the industry-leading Speedway Revolution RFID reader and Impinj's Dual-Linear Phased Array (DLPA) antenna technology into a high performing, flexible, and cost-effective RFID portal solution. This system solves the size and mounting limitations of traditional portals with an attractive, light-weight, and low-profile unit. The xPortal's DLPA antenna technology utilizes beam switching and polarization attributes that are dynamically managed by the reader, providing consistent and broad coverage of the read zone. This xPortal RFID reader is ideal for monitoring tagged items, pallets, equipment, files, or people passing through doorways, hallways, or other zonal coverage areas.
