With RF Edge Detection (without RFID)
We speak about 'detection distance' in this case.
When RF Edge Detection is enabled, the following recommendations are in place:
For the FL30R gate: a detection distance of 85 cm (2.8 ft) is recommended.
For the FL45R gate: a detection distance of 100 cm (3.3 ft) is recommended.
We recommend to have a RF label-free zone of more than 150 cm (4.9 ft.) from the center of the antenna
behind the antenna, and 100 cm (3.3 ft.) into the store.
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.
