RF installation requirements
The operation of RF technology is affected by both coupling issues (the antenna couples with other objects)
and by active interferers (other devices that transmit a signal around 8.2 MHz). Objects that cause coupling
effects could be windows, doors, metal framing around the checkout, etc. Interferers can be created by
another RF system, but also motors driving doors or roller shutters.
Take the following placement requirements into account when projecting the location of gates:
There should be a minimum distance of 20 cm (8 in.) between the center of the gate and the wall.
There should be a minimum distance of 200 cm (6.6 ft.) between 8.2 MHz tags and/or labels and the
nearest antenna. If this is not possible, the labels and tags can be stored in a metal box in the checkout.
In addition, when or are present:normal sliding doors
There should be a minimum distance of 40 cm (16 in.) between the center of the gate and the door.
