3.1 Operation
The xSpan Gateway is a high performance RAIN RFID reader system with an integrated
phased array antenna. The phase array antenna supports thirteen beams organized into three
sectors. Each beam can be either horizontally or vertically polarized. An on-board processor
controls the beam direction, orientation and polarization. The system has the capability to
steer its antenna beam along a single axis to read RFID tags over a rectangular area and
detect item movement. The gateway can be mounted on a ceiling or a wall with power and
control through a Power over Ethernet (PoE) connection.
